Abstract
OBJECTIVE Evaluate whether traumatic brain injury (TBI) characteristics, age of injury, or recency of injury predicts the course of neurocognitive decline and/or increases conversion rates to mild cognitive impairment (MCI) or dementia. METHODS Data were obtained from the National Alzheimer's Coordinating Center for participants 50-85 years old with 3-5 visits from 2015 to 2022, with or without TBI history (TBI+ = 508; TBI- = 2,382). Groups were stratified by self-reported TBI history (i.e., single TBI without loss of consciousness [LOC], single TBI with LOC, multiple TBI without LOC, and multiple TBI with LOC), age of most recent TBI, and recency of TBI. Mixed linear models compared neuropsychological composite trajectories (executive functioning/attention/speed, language, memory, and global), co-varying for age, gender, education, apolipoprotein E4 status, race/ethnicity, and baseline diagnosis (normal aging n = 1,720, MCI n = 749, or dementia n = 417). Logistic binary regression examined MCI/dementia conversion rates. RESULTS There was a slightly higher frequency of MCI/dementia in those with multiple TBIs (50% to 60% with and without LOC, compared to 39% with no TBI) at baseline, but longitudinal trajectories were similar. TBI history, age of injury, or recency of injury did not impact neurocognitive trajectories or conversion rates to MCI/dementia (all p's > .01). CONCLUSIONS TBI history, regardless of injury characteristics, age of injury, or recency of injury, did not worsen neurocognitive decline or MCI/dementia conversion. Additional longitudinal research in more diverse cohorts with a wider range of TBI severity is needed to evaluate the specific factors and possible mechanisms in which TBI may increase dementia risk.

Abstract
Objective Early detection of cognitive impairment in the elderly is crucial for diagnosis and appropriate care. Brief, cost-effective cognitive screening instruments are needed to help identify individuals who require further evaluation. This study presents preliminary data on a new screening technology using automated voice recording analysis software in a Spanish population. Method Data were collected from 174 Spanish-speaking individuals clinically diagnosed as cognitively normal (CN, n = 87) or impaired (mild cognitive impairment [MCI], n = 63; all-cause dementia, n = 24). Participants were recorded performing four common language tasks (Animal fluency, alternating fluency [sports and fruits], phonemic "F" fluency, and Cookie Theft Description). Recordings were processed via text-transcription and digital-signal processing techniques to capture neuropsychological variables and audio characteristics. A training sample of 122 subjects with similar demographics across groups was used to develop an algorithm to detect cognitive impairment. Speech and task features were used to develop five independent machine learning (ML) models to compute scores between 0 and 1, and a final algorithm was constructed using repeated cross-validation. A socio-demographically balanced subset of 52 participants was used to test the algorithm. Analysis of covariance (ANCOVA), covarying for demographic characteristics, was used to predict logistically-transformed algorithm scores. Results Mean logit algorithm scores were significantly different across groups in the testing sample (p < 0.01). Comparisons of CN with impaired (MCI + dementia) and MCI groups using the final algorithm resulted in an AUC of 0.93/0.90, with overall accuracy of 88.4%/87.5%, sensitivity of 87.5/83.3, and specificity of 89.2/89.2, respectively. Conclusion Findings provide initial support for the utility of this automated speech analysis algorithm as a screening tool for cognitive impairment in Spanish speakers. Additional study is needed to validate this technology in larger and more diverse clinical populations.

Abstract
OBJECTIVE to establish a proof-of-concept and ascertain the reliability of an abbreviated 30-second (30s) phonemic fluency measure as a cognitive screening tool in older adults. METHODS in all, 201 English-speaking individuals with normal cognition (NC; n = 119) or cognitive impairment (CI; mild CI or dementia; n = 82) were administered a standard 60s phonemic fluency task (FAS/CFL) with discrete 30s intervals denoted. RESULTS for all letters, 30s trial scores significantly predicted 60s scores for the same letter, R2 = .7-.9, F(1, 200) = 850-915, p < .001. As with 60s total scores, 30s cumulative scores (for all three trials) were significantly different between NC and CI groups (p < .001). Receiver operating characteristic analyses showed that 30s total scores distinguished NC and CI groups as effectively (AUC = .675) as 60s total scores (AUC = .658). CONCLUSIONS these findings support the utility and reliability of a short-form phonemic fluency paradigm, as 30s performance reliably predicted 60s/trial totals and was equally accurate in distinguishing impaired/non-impaired groups.

Abstract
BACKGROUND Growing evidence suggests that intensive lowering of systolic blood pressure (BP) may prevent mild cognitive impairment (MCI) and dementia. However, current guidelines provide inconsistent recommendations regarding optimal BP targets, citing safety concerns of excessive BP lowering in the diverse population of older adults. We are conducting a pragmatic trial to determine if an implementation strategy to reduce systolic BP to <130 and diastolic BP to <80 mmHg will safely slow cognitive decline in older adults with hypertension when compared to patients receiving usual care. METHODS The Preventing Cognitive Decline by Reducing BP Target Trial (PCOT) is an embedded randomized pragmatic clinical trial in 4000 patients from two diverse health-systems who are age ≥ 70 years with BP >130/80 mmHg. Participants are randomized to the intervention arm or usual care using a permuted block randomization within each health system. The intervention is a combination of team-based care with clinical decision support to lower home BP to <130/80 mmHg. The primary outcome is cognitive decline as determined by the change in the modified Telephone Interview for Cognitive Status (TICS-m) scores from baseline. As a secondary outcome, patients who decline ≥3 points on the TICS-m will complete additional cognitive assessments and this information will be reviewed by an expert panel to determine if they meet criteria for MCI or dementia. CONCLUSION The PCOT trial will address the effectiveness and safety of hypertension treatment in two large health systems to lower BP targets to reduce risk of cognitive decline in real-world settings.

Abstract
OBJECTIVE The primary aim of this paper is to accelerate the number of randomized experimental studies of the reliability and validity in-home tele-neuropsychological testing (tele-np-t). METHOD We conducted a critical review of the tele-neuropsychology literature. We discuss this research in the context of the United States' public and private healthcare payer systems, including the Centers for Medicare & Medicaid Services (CMS) and Current Procedural Terminology (CPT) coding system's telehealth lists, and existing disparities in healthcare access. RESULTS The number of tele-np publications has been stagnant since the onset of the COVID-19 pandemic. There are less published experimental studies of tele-neuropsychology (tele-np), and particularly in-home tele-np-t, than other tele-np publications. There is strong foundational evidence of the acceptability, feasibility, and reliability of tele-np-t, but relatively few studies of the reliability and validity of in-home tele-np-t using randomization methodology. CONCLUSIONS More studies of the reliability and validity of in-home tele-np-t using randomization methodology are necessary to support inclusion of tele-np-t codes on the CMS and CPT telehealth lists, and subsequently, the integration and delivery of in-home tele-np-t services across providers and institutions. These actions are needed to maintain equitable reimbursement of in-home tele-np-t services and address the widespread disparities in healthcare access.

Abstract
OBJECTIVE The primary aim of this paper is to review evidence and clinical implications related to lifestyle activities associated with promoting brain and cognitive health. Our review targets four key lifestyle factors: physical activity and exercise, social engagement, cognitively stimulating activity, and consuming Mediterranean-style diets. METHOD We conducted a critical review of the lifestyle factor literature in the four domains listed earlier. We contextualize this literature review by translating findings, when possible, into evidence-based recommendations to consider when providing neuropsychological services. RESULTS There is significant current evidence supporting the role of physical activity and exercise, social engagement, cognitively stimulating activity, and consuming Mediterranean-style diets on positive brain and cognitive health outcomes. While some null findings are present in all four areas reviewed, the weight of the evidence supports the notion that engaging in these activities may promote brain and cognitive functioning. CONCLUSIONS Clinical neuropsychologists can have confidence in recommending engagement in physical activity, social activity, and cognitively stimulating activity, and adhering to a Mediterranean-style diet to promote brain and cognitive health. We discuss limitations in existing lifestyle factor research and future directions to enhance the existing evidence base, including additional research with historically underrepresented groups and individuals with neurological conditions.

Abstract
OBJECTIVE To investigate whether routine daily activities (RDA), non-prescribed exercise (Non-ERx), or prescribed exercise (ERx) were associated with recovery from sport-related concussion (SRC) in collegiate athletes. MATERIALS AND METHODS Data for this cross-sectional, retrospective chart review of collegiate athletes diagnosed with SRC (n = 285[39.6% female], age = 19.5 ± 1.4 years) were collected during the 2015-16 to 2019-20 athletic seasons. The independent variable was group (RDA, Non-ERx, ERx). Dependent variables included days from date of diagnosis to symptom resolution (Dx-SR) and SR to return to sport (SR-RTS). RESULTS Those in the Non-ERx group took nearly 1.3 times longer to achieve SR (IRR = 1.28, 95% CI: 1.11, 1.46) and, 1.8 times longer for RTS (IRR = 1.82, 95% CI: 1.11, 2.71) when compared to those in the RDA group. No other comparisons were significant. CONCLUSION Collegiate athletes in the Non-ERx group took approximately 1 week longer to achieve SR as compared to the RDA and ERx groups. Our findings suggest that if exercise is recommended following SRC, it must be clearly and specifically prescribed. If exercise parameters cannot be prescribed, or monitored, RDA appear to be similarly beneficial during recovery for collegiate athletes with concussion.

Abstract
OBJECTIVE To investigate the association between sport type (collision, contact, non-contact) and subsequent injury risk following concussion in collegiate athletes. MATERIALS AND METHODS This retrospective chart review of 248 collegiate athletes with diagnosed concussions (age: 20.0 ± 1.4 years; height: 179.6 ± 10.9 cm; mass: 79.0 ± 13.6 kg, 63% male) from NCAA athletic programs (n = 11) occurred between the 2015-2020 athletic seasons. Acute injuries that occurred within six months following concussion were evaluated. Subsequent injuries were grouped by lower extremity, upper extremity, trunk, or concussion. The independent variable was sport type: collision, contact, non-contact. A Cox proportional hazard model was used to assess the risk of subsequent injury between sport types. RESULTS Approximately 28% (70/248) of athletes sustained a subsequent acute injury within six months post-concussion. Collision sport athletes had a significantly higher risk of sustaining any injury (HR: 0.41, p < 0.001, 95% CI: 0.28, 0.62), lower extremity (HR: 0.55, p = 0.04, 95% CI: 0.32, 0.97), and upper extremity (HR: 0.41, p = 0.01, 95% CI: 0.20, 0.81) injuries following concussion. No differences between sport types were observed for other injuries. CONCLUSION Collision sport athletes had a higher rate of any subsequent injury, lower, and upper extremity injuries following concussion. Future research should focus on sport-specific secondary injury prevention efforts.

Abstract
BACKGROUND Traumatic brain injury (TBI) has been linked to multiple pathophysiological processes that could increase risk for Alzheimer's disease and related dementias (ADRD). However, the impact of prior TBI on blood biomarkers for ADRD remains unknown. OBJECTIVE Using cross-sectional data, we assessed whether a history of TBI influences serum biomarkers in a diverse cohort (approximately 50% Hispanic) with normal cognition, mild cognitive impairment, or dementia. METHODS Levels of glial fibrillary acidic protein (GFAP), neurofilament light (NFL), total tau (T-tau), and ubiquitin carboxy-terminal hydrolase-L1 (UCHL1) were measured for participants across the cognitive spectrum. Participants were categorized based on presence and absence of a history of TBI with loss of consciousness, and study samples were derived through case-control matching. Multivariable general linear models compared concentrations of biomarkers in relation to a history of TBI and smoothing splines modelled biomarkers non-linearly in the cognitively impaired groups as a function of time since symptom onset. RESULTS Each biomarker was higher across stages of cognitive impairment, characterized by clinical diagnosis and Mini-Mental State Examination performance, but these associations were not influenced by a history of TBI. However, modelling biomarkers in relation to duration of cognitive symptoms for ADRD showed differences by history of TBI, with only GFAP and UCHL1 being elevated. CONCLUSIONS Serum GFAP, NFL, T-tau, and UCHL1 were higher across stages of cognitive impairment in this diverse clinical cohort, regardless of TBI history, though longitudinal investigation of the timing, order, and trajectory of the biomarkers in relation to prior TBI is warranted.

Abstract
OBJECTIVE It has been suggested that sport-related concussion (SRC) occurs more commonly on natural grass compared with artificial turf in contact sports. As playing surface is a potentially modifiable risk factor, this study sought to identify differences in symptoms following SRC on these 2 surfaces in a sample of young American football players. DESIGN Prospective. SETTING Part of the multi-institutional North Texas Concussion Registry (ConTex) research project. PARTICIPANTS Ten-year-old to 24-year-old male American football players (n = 62) who had sustained a helmet-to-ground SRC and presented to a specialty concussion clinic within 14 days of injury. INDEPENDENT VARIABLES Helmeted impact with grass (n = 33) or artificial turf (n = 29). MAIN OUTCOME MEASURES Severity and number of symptoms endorsed on the Sport Concussion Assessment Tool 5th Edition (SCAT5) Symptom Evaluation at the time of initial clinical evaluation. RESULTS Both groups were similar in mean time since injury, concussion history, and history of headache, but the artificial turf group was slightly older, with a mean age of 14.6 versus 13.6 years (P = 0.039). Athletes who sustained a SRC on grass reported significantly higher mean total symptom severity scores (26.6 vs 11.6, P = 0.005) and total number of symptoms (10.3 vs 5.9, P = 0.006) compared with those who were injured on artificial turf. CONCLUSIONS This may be the first study to examine postconcussive symptoms after SRC as they relate to playing surface. This small sample of young American football players reported higher symptom severity scores and higher total number of symptoms after SRC on natural grass compared with artificial turf.

Abstract
Athletic programs are more frequently turning to computerized cognitive tools in order to increase efficiencies in concussion assessment. However, assessment using a traditional neuropsychological test battery may provide a more comprehensive and individualized evaluation. Our goal was to inform sport clinicians of the best practices for concussion assessment through a systematic literature review describing the psychometric properties of standard neuropsychological tests and computerized tools. We conducted our search in relevant databases including Ovid Medline, Web of Science, PsycINFO, and Scopus. Journal articles were included if they evaluated psychometric properties (e.g., reliability, sensitivity) of a cognitive assessment within pure athlete samples (up to 30 days post-injury). Searches yielded 4,758 unique results. Ultimately, 103 articles met inclusion criteria, all of which focused on adolescent or young adult participants. Test-retest reliability estimates ranged from .14 to .93 for computerized tools and .02 to .95 for standard neuropsychological tests, with strongest correlations on processing speed tasks for both modalities, although processing speed tasks were most susceptible to practice effects. Reliability was improved with a 2-factor model (processing speed and memory) and by aggregating multiple baseline exams, yet remained below acceptable limits for some studies. Sensitivity to decreased cognitive performance within 72 h of injury ranged from 45%-93% for computerized tools and 18%-80% for standard neuropsychological test batteries. The method for classifying cognitive decline (normative comparison, reliable change indices, regression-based methods) affected sensitivity estimates. Combining computerized tools and standard neuropsychological tests with the strongest psychometric performance provides the greatest value in clinical assessment. To this end, future studies should evaluate the efficacy of hybrid test batteries comprised of top-performing measures from both modalities.

Abstract
OBJECTIVE To investigate whether a functional decline in cognitive activities decades after moderate-to-severe traumatic brain injury (m-sTBI) might relate to injury features and/or lifetime health factors, some of which may emerge as consequences of the injury. DESIGN Secondary analysis of the TBI Model Systems National Database, a prospective, multi-center, longitudinal study of patients with m-sTBI. SETTING TBI Model Systems Centers. PARTICIPANTS Included were 732 participants rated on the cognitive subscale of the Functional Independence Measure (FIM Cognitive), a metric for everyday cognitive skills, across 3 time points out to 20 years (visits at 2-, 10-, and 20-year follow-ups; N=732). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURE(S) FIM Cognitive Scale. Injury characteristics such as timing and features pertaining to severity and health-related factors (eg, alcohol use, socioeconomic status) were examined to discriminate stable from declining participants on the FIM Cognitive Scale using logistic regression. RESULTS At 20 years post-injury, there was a low base rate of FIM Cognitive decline (11%, n=78), with most being stable or having meaningful improvement (89%, n=654). Older age at injury, longer duration of post-traumatic amnesia, and presence of repetitive seizures were significant predictors of FIM Cognitive decline in the final model (area under the curve=0.75), while multiple health-related factors that can represent independent co-morbidities or possible consequences of injury were not. CONCLUSION(S) The strongest contributors to reported functional decline in cognitive activities later-in-life were related to acute characteristics of m-sTBI and experiencing post-traumatic seizures. Future studies are needed integrating functional with performance-based cognitive assessments to affirm conclusions and identify the timeline and trajectory of cognitive decline.

Abstract
OBJECTIVE Traumatic brain injury (TBI) history is associated with dementia risk, but it is unclear whether TBI history significantly hastens neurocognitive decline in older adults. METHOD Data were derived from the National Alzheimer's Coordinating Center (NACC) data set. Participants with a history of TBI (TBI +; n = 1,467) were matched to individuals without a history of TBI (TBI-; n = 1,467) based on age (50-97, M = 71.61, SD = 8.40), sex, education, race, ethnicity, cognitive diagnosis, functional decline, number of Apolipoprotein ε4 (APOE ε4) alleles, and number of annual visits (3-6). Mixed linear models were used to assess longitudinal neuropsychological test composite scores of executive functioning/attention/speed, language, and memory in TBI + and TBI- participants. Interactions between TBI and demographics, APOE ε4 status, and cognitive diagnosis were also examined. RESULTS Longitudinal neuropsychological functioning did not differ between TBI groups (p's > .001). There was a significant three-way interaction (age, TBI history, time) in language (F[20, 5750.1] = 3.133, p < .001) and memory performance (F[20, 6580.8] = 3.386, p < .001), but post hoc analyses revealed TBI history was not driving this relationship (all p's > .096). No significant interactions were observed between TBI history and sex, education, race/ethnicity, number of APOE ε4 alleles, or cognitive diagnosis (p's > .001). CONCLUSIONS Findings suggest TBI history, regardless of demographic factors, APOE ε4 status, or cognitive diagnosis, does not alter the course of neurocognitive functioning later-in-life in older adults with or without cognitive impairment. Future clinicopathological longitudinal studies that well-characterize head injuries and the associated clinical course are needed to help clarify the mechanism in which TBI may increase dementia risk.

Abstract
OBJECTIVE The mechanisms for traumatic brain injury (TBI) being a risk factor for Alzheimer's disease is unclear, and whether mild TBI (mTBI) may relate to decreased neural circuit functioning in the prodromal phase is unknown. This study examined whether a history of mTBI was associated with lower functioning of neural circuits, measured with neuropsychological tasks, in amnestic Mild Cognitive Impairment (aMCI). METHOD Twenty older adults (MAge = 71 years; 70% Male; 90% White) with aMCI were recruited to complete a detailed TBI interview and were classified based on the presence (mTBI+ n = 13) or absence (mTBI- n = 7) of past mTBI. Most mTBI+ participants (n = 11) had multiple mTBIs, and on average were 32 years from last injury. A comprehensive neuropsychological assessment was administered, and composite T-scores were calculated for the domains of attention, executive functioning, memory, and language. One-tailed T-tests were conducted to compare the means between groups. RESULTS No statistically significant differences (p's = 0.06-0.09) were found between the groups in memory (mTBI+ M = 38.11; mTBI- M = 33.19), executive function (mTBI+ M = 48.79; mTBI- M = 43.09), language (mTBI+ M = 48.12; mTBI- M = 43.09), or attention (mTBI+ M = 40.54; mTBI- M = 35.57). Nonetheless, medium effect sizes were seen for the mTBI+ group performing better than the mTBI- group on all composite scores (Cohen's d = 0.45-0.66). CONCLUSIONS A history of mTBI was not associated with poorer neuropsychological performance in aMCI, often a prodromal stage of Alzheimer's disease. While concerns about later-in-life effects from multiple mTBIs is prevalent, repetitive mTBI may not be related to lower neural circuit functioning in aMCI, though further evaluation with larger samples is needed.

Abstract
OBJECTIVE The long-term cognitive effects of traumatic brain injury (TBI) in military personnel remain unclear and need to be better understood. We assessed how cognitive performance was related to the remote history of TBI involving loss of consciousness (LOC) and blast injury (regardless of LOC) in veterans. METHOD Veterans (N = 101; age 42.8 ± 10.5 years; 10 Females) with a self-reported history of TBI and persistent cognitive symptoms were recruited. Effects of (1) the presence of LOC, (2) total number of TBIs with LOC (0, 1-2, >2), and (3) the presence of blast injury were examined on composite scores from tests of executive function (Trail-Making Test B, Color Word Interference), word retrieval (Boston Naming, Letter and Category Fluency), processing speed (Trail Making-A, Color Word Naming/Reading), and episodic memory (Rey-Auditory Verbal Learning Test-total learning and delayed recall), while controlling for age, sex, years of education, and total number of TBIs. RESULTS TBI with LOC was a significant predictor of executive function (p = 0.014) and processing speed (p = 0.014), with more episodes of LOC predicting lower functioning, but not of word retrieval or episodic memory (p > 0.1). Additionally, presence of a blast injury, regardless of LOC, did not predict differences in function on any of the composite measures. CONCLUSIONS Self-reported TBI history with LOC was associated with poorer executive function and processing speed. The findings further characterize the relationship between TBI history and long-term cognitive sequelae in veterans, particularly suggesting LOC can affect neural systems underlying executive function and processing speed.

Abstract
OBJECTIVE AcceXible is a new Artificial Intelligence (AI) tool that identifies speech biomarkers for cognitive impairment that was developed in Spain. Good sensitivity (85.7%) and specificity (92.8%) in distinguishing patients with mild cognitive impairment from individuals with normal functioning have been established with populations in Spain, and preliminary data are similar in the United States and the United Kingdom. In this study, we assessed transcription accuracy for Spanish speakers in the US originating from Latin American countries (LAC) and the effect it may have on the performance of Accexible's AI model. METHOD AcceXible involves participants completing several verbal tasks via computer interface, including Animal Naming (AN). Transcription accuracy for 16 Spanish-speaking patients from LAC in Texas was assessed by comparing data obtained from hand scoring of AcceXible AN to data from different customized expressive language transcription tools used in AcceXible's platform. The transcription tool was updated based on inconsistencies found. RESULTS AcceXible's customized transcription tool was initially found to miss 34% of total items on AN due to differences in vocabulary and pronunciation between LAC and Spain. The transcription tool was modified to recognize the LAC vocabulary and pronunciations, which resulted in 25.84% increased accuracy for an overall transcription accuracy of 91%. CONCLUSIONS AcceXible is a useful tool for efficiently assessing expressive language, and the current findings highlight the need to consider not just language, but also nationality when adapting tests across cultures.

Abstract
OBJECTIVE Resilience has been found to be a factor in concussion recovery, and the Brief Resilience Scale (BRS) has been validated as a measure of resilience in adults. Investigation of the BRS in adolescents with concussion and its relationship with current measures of anxiety, depression, and emotional symptoms may prove beneficial in further understanding emotional response to concussions in adolescents. METHOD Participants aged 12-17 who sustained a concussion (n = 1168) were evaluated within 30 days of injury at a North Texas Concussion Registry (ConTex) clinic. Participants completed the Brief Resilience Scale (BRS), the General Anxiety Disorder 7 scale (GAD-7), the Patient Health Questionnaire depression scale (PHQ-8), and the emotional cluster (feeling irritable, sad, nervous, and more emotional) of the Sport Concussion Assessment Tool 5th Edition Symptom Evaluation (SCAT5) at initial visit. Pearson's correlation coefficient (r) was used to determine the relationship between scores on these four measures. RESULTS Pearson correlations between BRS scores and scores from the other measures were modest but statistically significant: GAD-7 (r = -0.392, p < 0.001), PHQ-8 (r = -0.321, p < 0.001), and the emotional cluster of the SCAT5 (r = -0.301, p < 0.001). CONCLUSIONS Comparison of BRS score with GAD-7, PHQ-8, and the emotional cluster of the SCAT5 indicates that resilience may exhibit a modest inverse correlation with screening measures of anxiety, depression, and emotional symptoms, and thus a discrete factor for use in evaluating initial emotional response to concussion in adolescents.

Abstract
OBJECTIVE Evaluate if traumatic brain injury (TBI) characteristics, age of injury, or recency of injury is related to course of neurocognitive decline in aging and/or increases conversion rates to mild cognitive impairment (MCI) or all-cause dementia later in life. METHODS Data were obtained from the National Alzheimer's Coordinating Center for participants 50-85 years old with 3 to 5 visits from 2015-2022. Groups were stratified by: 1) self-reported TBI history (No TBI [n = 2382], Single TBI without loss of consciousness [LOC; n = 102], Single TBI w/LOC [n = 228], Multiple TBI without LOC [n = 36], and Multiple TBI w/LOC [n = 115]), 2) age of most recent TBI (No TBI [n = 2382], TBI = 65 years old [n = 76]), and 3) recency of TBI (no TBI [n = 2382], 15 years ago [n = 301]). Mixed linear models compared normed neuropsychological composite trajectories (executive functioning/attention/speed, language, memory, and overall), co-varying for age, gender, education, apolipoprotein E4 status, and baseline diagnosis (normal aging n = 1720, MCI n = 749, or dementia n = 417). Logistic binary regression examined MCI/dementia conversion rates. RESULTS Longitudinal neurocognitive trajectories in composite measures were similar among TBI groups (example figure below). Specific TBI history, age of injury, or recency of injury did not impact neurocognitive trajectories or conversion rates to MCI or dementia (all p's > 0.01). CONCLUSIONS TBI history, regardless of injury characteristics, age, or recency, did not worsen neurocognitive decline or MCI/dementia conversion. The mechanism and factors that increase dementia risk after TBI are unclear. Additional longitudinal research in carefully designed longitudinal cohorts is needed.

Abstract
OBJECTIVE To compare mild cognitive impairment (MCI) and dementia conversion rates between global neuropsychological dispersion (GD) and traditional memory neuropsychological composite score (MComp) in participants with baseline evidence of cognitive decline but no diagnosis of MCI or dementia. METHODS Data from the National Alzheimer's Coordinating Center (NACC) for 364 participants with a CDR of 0.5, no initial diagnosis of MCI or dementia, and five visits were analyzed. GD was the intraindividual standard deviation across baseline normative (NACC norms) neuropsychological performance. MComp was the mean of the four verbal and visual memory normed scores. Multinomial logistic regression models fit statistics compared GD and MComp as predictors of conversion to MCI/dementia, adjusting for age, sex, race, ethnicity, ApoE4 status, and stratified by suspected etiology (Alzheimer's disease [ad] or no-ad). Lower Akaike Information Criteria (AIC) values indicate better model fit and predictions. RESULTS 37% progressed to MCI, and 47% to dementia by visit 5. 53% of these were suspected to have ad etiology, and 47% non-ad. MComp showed a better fit with significant predictions of MCI and dementia progression in both suspected ad (AIC: 351.77, p < 0.001) or non-ad etiology (AIC: 215.02, p < 0.004), versus GD was only significant for non-ad etiology (AIC: 385.74, p < 0.003). Better memory performance predicted a lower likelihood of conversion to non-ad MCI (B = -0.65, p = 0.003) and non-ad dementia (B = -1.33, p < 0.001). GD predicted eventual progression to non-ad dementia (B = 2.311, p = 0.004), but not non-ad MCI. CONCLUSION Traditional memory composite score may be a better predictor of MCI and dementia conversion than cognitive dispersion in individuals with early cognitive decline who do not yet meet MCI criteria.

Abstract
INTRODUCTION The risk reduction for Alzheimer's disease (rrAD) trial was a multisite clinical trial to assess exercise and intensive vascular pharmacological treatment on cognitive function in community-dwelling older adults at increased risk for Alzheimer's disease. METHODS Eligibility, consent, and randomization rates across different referral sources were compared. Informal interviews conducted with each site's project team were conducted upon study completion. RESULTS Initially, 3290 individuals were screened, of whom 28% were eligible to consent, 805 consented to participate (87.2% of those eligible), and 513 (36.3% of those consented) were randomized. Emails sent from study site listservs/databases yielded the highest amount (20.9%) of screened individuals. Professional referrals from physicians yielded the greatest percentage of consented individuals (57.1%). Referrals from non-professional contacts (ie, friends, family; 75%) and mail/phone contact from a site (73.8%) had the highest yield of randomization. DISCUSSION Professional referrals or email from listservs/registries were most effective for enrolling participants. The greatest yield of eligible/randomized participants came from non-professional and mail/phone contacts. Future trials should consider special efforts targeting these recruitment approaches. Highlights Clinical trial recruitment is commonly cited as a significant barrier to advancing our understanding of cognitive health interventions.The most cited referral source was email, followed by interviews/editorials on the radio, television, local newspapers, newsletters, or magazine articles.The referral method that brought in the largest number of contacts was email but did not result in the greatest yield of consents or eligible participants.The sources that yielded the greatest likelihood of consent were professional referrals (ie, physician), social media, and mail/phone contact from study site.The greatest yield of eligible/randomized participants came from non-professional contacts and mail/phone contact from a site.Findings suggest that sites may need to focus on more selective referral sources, such as using contact mailing and phone lists, rather than more widely viewed recruitment sources, such as social media or TV/radio advertisements.

Abstract
Objective: Persisting concussion symptoms may adversely affect return to work and functioning in daily activities. This study compared adults who were initially evaluated < 30 days versus those evaluated ≥ 30 days following a concussion at a specialty concussion clinic to determine if delayed initial evaluation is associated with persisting symptoms during recovery. Method: Participants (N = 205) 18 years of age and older who sustained a concussion and presented to a North Texas Concussion Registry (ConTex) clinic were evaluated at two time points: initial clinical visit and three-month follow-up. Participants provided medical history, injury related information, and completed the Sport Concussion Assessment Tool-5 Symptom Evaluation, Generalized Anxiety Disorder 7-item scale (GAD-7), and Patient Health Questionnaire (PHQ-8). Participants were divided into two groups: early and delayed evaluation (±30 days post injury). Results: Number and severity of concussion symptoms were similar between both groups at their initial clinical visit. However, linear regression models showed that a delayed clinical evaluation was associated with a greater number and severity of concussion symptoms along with greater aggravation of symptoms from physical and cognitive activity at three-month follow-up. Conclusions: Individuals who sought care at specialty concussion clinics regardless of previous care 30 or more days following their injury reported more serious persisting concussion symptoms at three month follow-up than those who sought care sooner. Education to improve adults' recognition of concussions when they occur and obtaining earlier clinical evaluation may represent important opportunities in promoting better recovery and reducing persisting concussion symptoms.

Abstract
OBJECTIVES Youth soccer participation, particularly among females, continues to grow worldwide. With the high incidence of sport-related concussion (SRC) in soccer, it is important to investigate if SRC occurs disproportionally by positions. Our hypothesis was to see no positional differences in SRCs, SRC-related characteristics, and outcomes among in female youth soccer athletes. METHODS Data were prospectively collected from participants at a single sports medicine institution between August 2015-April 2021. Female participants aged 8-18 diagnosed with SRC sustained during an organized soccer practice, scrimmage, or game were separated into 4 groups based on position: Forward, Midfielder, Defender, and Goalkeeper. Demographics, medical history, injury-related details, and outcomes were reviewed. A chi-square test or Fisher's exact test was used for categorical variables. Continuous variables were compared with Mann-Whitney or Kruskal-Wallis test. RESULTS Two hundred fourteen participants were included: 52 Forwards, 65 Midfielders, 63 Defenders, and 34 Goalkeepers. There were no significant differences between the groups in age, race, ethnicity, or previous concussion history. Differences in mechanism existed with Goalkeepers most commonly reporting Head to Body Part. Goalkeepers, which make up 1/11 of the total positions on the field, had a significantly higher proportion of SRCs compared to Field Positions. (9.1% vs 15.9%)At 3-month post-enrollment, there were no significant differences in reported symptoms or return-to-play between the different positions. CONCLUSION In youth female soccer players, goalkeepers sustained a higher proportion of sport-related concussions compared to field players based upon the composition of a soccer team. The mechanism of injury also differed among the different soccer positions. However, no differences in concussion characteristics, outcomes, or RTP were seen across the different soccer positions.

Abstract
OBJECTIVE In a retrospective cohort, we evaluated whether age beginning tackle football (ABTF) and more total years of playing football (TYPF) were associated with worse later-in-life neuropsychological change among older retired National Football League (NFL) players. METHOD Participants were 19 older NFL retirees aged 54-79, including 12 who returned for follow-up evaluation 15-51 months later. Mixed-linear models evaluated the association between ABTF/TYFP and baseline neuropsychological composite scores (executive functioning/attention/speed, language, memory), and neuropsychological composites over time. RESULTS ABTF and TYPF were not significantly associated with neuropsychological composites at baseline or over time (all p's > .05). There were no significant differences in neuropsychological performance between those ABTF <12 and ≥ 12 years old (all p's ≥ .475) or between those with TYPF <19 or ≥ 19 years played (median split; all p's ≥ .208). CONCLUSIONS Preliminary findings suggest that ABTF and TYPF does not worsen neurocognitive decline later-in-life among older NFL retirees.

Abstract
OBJECTIVE A variety of factors affect list learning performance and relatively few studies have examined the impact of word selection on these tests. This study examines the effect of both language and memory processing of individual words on list learning. METHOD Item-response data from 1,219 participants, Mage = 74.41 (SD = 7.13), Medu = 13.30 (SD = 2.72), in the Harmonized Cognitive Assessment Protocol were used. A Bayesian generalized (non)linear multilevel modeling framework was used to specify the measurement and explanatory item-response theory models. Explanatory effects on items due to learning over trials, serial position of words, and six word properties obtained through the English Lexicon Project were modeled. RESULTS A two parameter logistic (2PL) model with trial-specific learning effects produced the best measurement fit. Evidence of the serial position effect on word learning was observed. Robust positive effects on word learning were observed for body-object integration while robust negative effects were observed for word frequency, concreteness, and semantic diversity. A weak negative effect of average age of acquisition and a weak positive effect for the number of phonemes in the word were also observed. CONCLUSIONS Results demonstrate that list learning performance depends on factors beyond the repetition of words. Identification of item factors that predict learning could extend to a range of test development problems including translation, form equating, item revision, and item bias. In data harmonization efforts, these methods can also be used to help link tests via shared item features and testing of whether these features are equally explanatory across samples.

Abstract
Importance Advocates of laparoscopic surgery argue that all inguinal hernias, including initial and unilateral ones, should be repaired laparoscopically. Prior work suggests outcomes of open repair are improved by using local rather than general anesthesia, but no prior studies have compared laparoscopic surgery with open repair under local anesthesia. Objective To evaluate postoperative outcomes of open inguinal hernia repair under general or local anesthesia compared with laparoscopic repair. Design, Setting, and Participants This retrospective cohort study identified 107 073 patients in the Veterans Affairs Surgical Quality Improvement Program database who underwent unilateral initial inguinal hernia repair from 1998 to 2019. Data were analyzed from October 2021 to March 2022. Exposures Patients were divided into 3 groups for comparison: (1) open repair with local anesthesia (n = 22 333), (2) open repair with general anesthesia (n = 75 104), and (3) laparoscopic repair with general anesthesia (n = 9636). Main Outcomes and Measures Operative time and postoperative morbidity were compared using quantile regression and inverse probability propensity weighting. A 2-stage least-squares regression and probabilistic sensitivity analysis was used to quantify and address bias from unmeasured confounding in this observational study. Results Of 107 073 included patients, 106 529 (99.5%) were men, and the median (IQR) age was 63 (55-71) years. Compared with open repair with general anesthesia, laparoscopic repair was associated with a nonsignificant 0.15% (95% CI, -0.39 to 0.09; P = .22) reduction in postoperative complications. There was no significant difference in complications between laparoscopic surgery and open repair with local anesthesia (-0.05%; 95% CI, -0.34 to 0.28; P = .70). Operative time was similar for the laparoscopic and open general anesthesia groups (4.31 minutes; 95% CI, 0.45-8.57; P = .048), but operative times were significantly longer for laparoscopic compared with open repair under local anesthesia (10.42 minutes; 95% CI, 5.80-15.05; P < .001). Sensitivity analysis and 2-stage least-squares regression demonstrated that these findings were robust to bias from unmeasured confounding. Conclusions and Relevance In this study, laparoscopic and open repair with local anesthesia were reasonable options for patients with initial unilateral inguinal hernias, and the decision should be made considering both patient and surgeon factors.

Abstract
Introduction Traumatic brain injury (TBI) may alter dementia progression, although co-occurring neuropsychiatric symptoms (NPS) have received less attention. Originally designed to evaluate behavioral disruption prior to dementia diagnosis, the mild behavioral impairment (MBI) construct relates NPS to underlying neural circuit disruptions, with probable relevance across the progression of neurodegenerative disease. Therefore, the MBI construct may represent a valuable tool to identify and evaluate related NPS both preceding diagnosis of all-cause dementia throughout the progression of disease, representing an important area of inquiry regarding TBI and dementia. This investigation sought to evaluate the effect of TBI on NPS related by the MBI construct in participants progressing from normal cognitive status to all-cause dementia. Methods Using National Alzheimer's Coordinating Center data, individuals progressing from normal cognition to all-cause dementia (clinician diagnosed) over 7.6 ± 3.0 years were studied to estimate prevalence of MBI domains in 124 participants with prior TBI history (57 with loss of consciousness [LOC] <5 minutes, 22 with LOC >5 min, 45 unknown severity) compared to 822 without. MBI domain prevalence was evaluated (1) prior to dementia onset (including only time points preceding time at dementia diagnosis, as per MBI's original definition) and (2) throughout dementia progression (evaluating all available time points, including both before and after dementia diagnosis). Results More severe TBI (LOC >5 minutes) was associated with the social inappropriateness MBI domain (adjusted odds ratio = 4.034; P = 0.024) prior to dementia onset, and the abnormal perception/thought content domain looking across dementia progression (adjusted hazard ratio [HRadj] = 3.703; P = 0.005). TBI (all severities) was associated with the decreased motivation domain looking throughout dementia progression (HRadj. = 1.546; P = 0.014). Discussion TBI history is associated with particular MBI profiles prior to onset and throughout progression of dementia. Understanding TBI's impact on inter-related NPS may help elucidate underlying neuropathology with implications for surveillance, detection, and treatment of behavioral concerns in aging TBI survivors. Highlights The mild behavioral impairment (MBI) construct links related neuropsychiatric symptoms (NPS) by probable underlying neural network dysfunction.Traumatic brain injury (TBI) with loss of consciousness (LOC) > 5 minutes was associated with pre-dementia social inappropriateness.TBI was associated with decreased motivation looking across dementia progression.TBI with LOC > 5 minutes was associated with abnormal perception/thought content.The MBI construct may be useful for examining related NPS across dementia progression.

Abstract
OBJECTIVE Determine if head-injury exposure relates to later-in-life cognitive decline in older National Football League (NFL) retirees. METHOD NFL retirees (aged 50+) with or without cognitive impairment underwent baseline (n = 53) and follow-up (n = 29; 13-59 months later) neuropsychological evaluations. Cognitively normal (CN) retirees (n = 26) were age- and education-matched to healthy controls (n = 26). Cognitively impaired (CI) retirees with mild cognitive impairment or dementia (n = 27) were matched to a clinical sample (CS) by age, sex, education, and diagnosis (n = 83). ANOVAs compared neuropsychological composites at baseline and over time between retirees and their matched groups. Regression models evaluated whether concussions, concussions with loss of consciousness (LOC), or games played predicted neuropsychological functioning. RESULTS At baseline, CN retirees had slightly worse memory than controls (MCN retirees = 50.69, SECN retirees = 1.320; MHealthy controls = 57.08, SEHealthy controls = 1.345; p = 0.005). No other group diferences were observed, and head-injury exposure did not predict neurocognitive performance at baseline or over time. CONCLUSIONS Head-injury exposure was not associated with later-in-life cognition, regardless of cognitive diagnosis. Some retirees may exhibit lower memory scores compared to age-matched peers, though this is of unclear clinical significance.

Abstract
Some children and adolescents have persistent concussion symptoms that extend beyond the typical 3-4 week recovery window. Our understanding about what to expect when recovery is atypical, particularly in elementary-age children, is incomplete because there are very few targeted studies of this age group in the published literature. Aims were to identify lingering symptoms that present at three months post-concussion and to determine what factors are associated with prolonged recovery in an elementary-age group. Participants were 123 children aged 5-10 years who were seen at specialized concussion clinics, divided into expected and late recovery groups. Parents rated concussion symptoms on a scale from the Sideline Concussion Assessment Tool-5 (SCAT-5). The most frequent symptoms were headache, irritability, feeling more emotional, and sensitivity to noise. Stepwise logistic regression determined that female sex and total symptom burden at initial visit, but not any specific symptom, predicted prolonged recovery. Clinicians are advised to carefully monitor children who report numerous symptoms after concussion, particularly when the concussed children are girls.

Abstract
Objective. Neuropsychological measures of processing speed have long been used as sensitive indices of cognitive functioning. Most of these commonly used tests are proprietary, and there is a need for brief, freely available tools that can be used in diverse clinical and research settings. The Southwestern Assessment of Processing Speed (SWAPS) is a 60-second digit-symbol transcription task developed as a brief alternative to commercially available coding tests. Demographically-corrected normative data are presented along with reliability and sensitivity/specificity values in older adults with and without cognitive impairment.Method. SWAPS data from 915 healthy aging individuals (NC) and 858 subjects with clinical diagnoses of mild cognitive impairment (MCI; n = 430) and Alzheimer's disease clinical syndrome (ADCS; n = 428) were obtained from the Texas Alzheimer's Research and Care Consortium (TARCC). TARCC participants represent ethnically and educationally diverse community-dwelling individuals age 50+.Results. SWAPS scores showed the expected associations with age, sex, and education, and the interaction between age and education were significant predictors of SWAPS scores. Test-retest reliability in NC was good, and the SWAPS distinguished impaired and non-impaired groups with adequate to excellent sensitivity and specificity for the primary analyses, with optimal cut-off points provided. Raw score- to uncorrected normalized T-scores and demographically-corrected SWAPS T-scores using regression-based norms are presented along with scoring programs for the calculation of each.Conclusions. The SWAPS is a brief, free, easily administered test with demographically-corrected regression-based norms and promising utility for detection of cognitive impairment and efficient assessment of processing speed.

Abstract
Subject motion is a well-known confound in resting-state functional MRI (rs-fMRI) and the analysis of functional connectivity. Consequently, several clean-up strategies have been established to minimize the impact of subject motion. Physiological signals in response to cardiac activity and respiration are also known to alter the apparent rs-fMRI connectivity. Comprehensive comparisons of common noise regression techniques showed that the "Independent Component Analysis based strategy for Automatic Removal of Motion Artifacts" (ICA-AROMA) was a preferred pre-processing technique for teenagers and adults. However, motion and physiological noise characteristics may differ substantially for older adults. Here, we present a comprehensive comparison of noise-regression techniques for older adults from a large multi-site clinical trial of exercise and intensive pharmacological vascular risk factor reduction. The Risk Reduction for Alzheimer's Disease (rrAD) trial included hypertensive older adults (60-84 years old) at elevated risk of developing Alzheimer's Disease (AD). We compared the performance of censoring, censoring combined with global signal regression, non-aggressive and aggressive ICA-AROMA, as well as the Spatially Organized Component Klassifikator (SOCK) on the rs-fMRI baseline scans from 434 rrAD subjects. All techniques were rated based on network reproducibility, network identifiability, edge activity, spatial smoothness, and loss of temporal degrees of freedom (tDOF). We found that non-aggressive ICA-AROMA did not perform as well as the other four techniques, which performed table with marginal differences, demonstrating the validity of these techniques. Considering reproducibility as the most important factor for longitudinal studies, given low false-positive rates and a better preserved, more cohesive temporal structure, currently aggressive ICA-AROMA is likely the most suitable noise regression technique for rs-fMRI studies of older adults.

Abstract
INTRODUCTION Lingering concussion symptoms can negatively impact a child's well-being, yet variability in recovery is poorly understood. To aid detection of those at risk for prolonged symptom duration, we explored postconcussion mood and sleep symptoms as predictors of recovery time in adolescent athletes. METHOD We utilized analyses designed to control for potentially confounding variables, such as concussion severity indicators and premorbid psychiatric history. Participants included 393 adolescent athletes (aged 12-18 years) evaluated in outpatient concussion clinics within 2 weeks after injury. Provider-documented date of symptom resolution was obtained via medical record review. Survival analysis for recovery time was conducted in the total sample, and separately for males and females using prior medical history (psychiatric disorder, prior concussion), injury-related factors (loss of consciousness, post-traumatic amnesia [PTA], concussion symptom severity), and psychological symptoms (General Anxiety Disorder-7 Item Scale, Patient Health Questionnaire-8 Item Depression Scale, Pittsburgh Sleep Quality Index) collected at initial clinic visit. RESULTS PTA, concussion symptoms, and sleep quality were associated with recovery in the total sample (HRs = 0.64-0.99, ps < .05). When analyzed by sex, only concussion symptoms were associated with recovery for females (with females reporting greater symptom severity than males), while for males PTA and greater depression symptoms were significant predictors of recovery (HRs = 0.54-0.98, ps < .05). CONCLUSIONS These findings identified differences in symptom presentation between sexes, particularly for mood symptoms, and suggest that assessment of postconcussive symptoms is useful in helping to identify individuals at risk for longer recovery. Continued exploration of post-injury psychological difficulties in athletes is warranted for better concussion management.

Abstract
OBJECTIVE Accurate assessment of balance recovery throughout treatment of a sport-related concussion is imperative. This study examined differences in balance from diagnosis to return-to-play initiation in adolescent patients post-concussion. Second, this study investigated the extent to which the Balance Error Scoring System (BESS) correlated with center-of-pressure (COP) measures. METHODS Forty participants performed the BESS while standing on a force platform such that COP data were obtained simultaneously. Spatial and velocity COP-based measures were computed for the double-stance conditions. RESULTS BESS scores and COP-based measures indicated improved balance performance between visits. Specifically, 62.5/65.0% of participants exhibited improved firm/foam BESS final scores, respectively, and 56.4-71.8% exhibited improved COP-based measures. However, once normative ranges were referenced to identify maintained performance, the percentage of participants who substantially improved differed from initial findings (BESS: 2.5/7.5%, COP: 48.7-69.2%). Additionally, positive correlations between balance measures were primarily found at diagnosis (r=0.33-0.53), while only three correlations were maintained at return-to-play initiation (r=0.34-0.39). CONCLUSIONS BESS scores successfully identified poor balance performance at diagnosis when symptoms were most pronounced, but failed to accurately depict performance once balance impairment, indicated by COP-based measures, became less apparent. Further work is needed to implement more advanced balance assessments into clinical environments.

Abstract
Purpose: Investigate the association of initial symptoms, mechanism of concussion, and emotional state with symptoms of stress reported during recovery from concussion in high school students. Methods: Concussed High School students (n = 183) aged 13–18 were evaluated within 30 days of injury at a North Texas Concussion Registry (ConTex) clinic with 71% (n = 130) sport-related. Subjects completed a medical history, the Sport Concussion Assessment Tool-5 Symptom Evaluation (PCSS), General Anxiety Disorder (GAD-7), and Patient Health Questionnaire-8 (PHQ-8) at initial visit. At three-month follow-up subjects completed the PTSD Checklist for DSM-5 (PCL-5). A linear regression was conducted predicting total scores on the follow up PCL-5. Predictors included initial Total PCSS Symptom Score, GAD-7, PHQ-8, sex, mechanism of injury (sport vs non-sport) and history of treatment for anxiety/depression. Results: A multiple regression model predicting participant’s total PCL-5 score at three month follow-up (R2 = 0.40, p < 0.001) included PHQ-8 (β = 0.34, p < 0.001), GAD-7 (β = 0.20, p = 0.016), history of treatment for depression (β = 0.17, p = 0.015), severity of initial symptoms (β = 0.15, p = 0.045) and mechanism of injury (β = −0.14, p = 0.018). There was no significant difference in PCL-5 scores between sport vs non-sport injury groups. Conclusions: Pre-existing depression and higher levels of self-reported anxiety and/or depression at time of injury may be associated with increased symptoms of stress during concussion recovery. Severity of initial symptoms and mechanism of injury may also be related to feelings of stress during recovery. Further investigations should include baseline measure of stress prior to injury.

Abstract
Abstract
Purpose: Demographic adjustments (e.g., age, sex, race/ethnicity) to neuropsychological tests can assist clinical interpretation and avoid false-positive diagnoses of cognitive impairment. The issue of “race” as a criterion for normative adjustment has been highlighted in recent cases among former NFL players. We examined the impact of different normative reference comparisons on neuropsychological scores among cognitively normal Black and White NFL retirees. Methods: Cognitively normal Black (n = 20) and White (n = 20) retirees were age- and education-matched. Measures of attention (Digit Span), processing speed (Coding, TMTA), memory (ROCFT, CVLT), language (FAS, Animals, BNT), and executive function (TMTB) were examined. Independent samples t-tests (using p < 0.01) were conducted between raw and normative scores of Black and White retirees that adjusted for 1) age/education (Mitrushina); 2) age/education/sex (NACC); and 3) age/education/sex/race (Heaton, MOANS/MOAANS). An additional ANCOVA evaluated group differences controlling for baseline estimated IQ. Results: Raw scores differed between groups on TMTB, Coding, and BNT. Mitrushina normative data showed differences on TMTB (p = 0.007) and BNT (p < 0.001). NACC normative data showed differences on the BNT (p < 0.001). ANCOVA (controlling for IQ) of raw scores between groups differed on the BNT (p = 0.002). Heaton and MOANS/MOAANS normative scores did not reveal differences between groups on any test. Conclusions: As expected, the use of different neuropsychological norms influences findings across different sociodemographic groups to various degrees, depending on the test. The underlying contributors to group differences using “race” as a proxy need to be disentangled and understood. Cautious use of demographically-adjusted norms as interpretive guidelines is warranted until these factors are identified.

Abstract
OBJECTIVE Ventriculoperitoneal (VP) shunting is commonly used to treat normal pressure hydrocephalus (NPH). Assessment of cognition and balance pre- and post-lumbar drain (LD) can be used to provide objective metrics which may help determine the potential benefit of VP shunting. The aim of this investigation was to determine which measures identify clinical change as a result of a LD trial and to develop recommendations for standard NPH clinical assessment procedures. METHODS The Berg Balance Scale (BBS) and a brief battery of commonly used neuropsychological tests pre- and post-LD (MMSE, trail making test, animal fluency, Hopkins Verbal Learning Test - Revised, and digit span) were administered to 86 patients with a diagnosis of NPH. Subjects were divided into groups based on whether or not clinical change was present, and thus, VP shunting was recommended post-LD, and predictors of group membership were examined. RESULTS Significant improvements (p < 0.05) were seen on the BBS and Trail Making Part B in the VP shunt-recommended group, with no other significant changes over time in either group. Regression analyses found that VP shunt recommendation was accurately predicted for 80% of the sample using the BBS score alone, with accuracy increasing to 85% when Trails B was added. CONCLUSIONS Scores from the BBS and Trails B were most likely to change in those chosen to undergo VP shunting post-LD. Given that the typical clinical presentation of NPH includes gait disturbance and cognitive impairment, it is recommended that a standard pre-/post-LD evaluation include the BBS and trail making test.

Abstract
Mounting evidence suggests that amyloid-β (Aβ) and vascular etiologies are intertwined in the pathogenesis of Alzheimer's disease (AD). Blood-oxygen-level-dependent (BOLD) signals, measured by resting-state functional MRI (rs-fMRI), are associated with neuronal activity and cerebrovascular hemodynamics. Nevertheless, it is unclear if BOLD fluctuations are associated with Aβ deposition in individuals at high risk of AD. Thirty-three patients with amnestic mild cognitive impairment underwent rs-fMRI and AV45 PET. The AV45 standardized uptake value ratio (AV45-SUVR) was calculated using cerebral white matter as reference, to assess Aβ deposition. The whole-brain normalized amplitudes of low-frequency fluctuations (sALFF) of local BOLD signals were calculated in the frequency band of 0.01-0.08 Hz. Stepwise increasing physiological/vascular signal regressions on the rs-fMRI data examined whether sALFF-AV45 correlations were driven by vascular hemodynamics, neuronal activities, or both. We found that sALFF and AV45-SUVR were negatively correlated in regions of default-mode and visual networks (precuneus, angular, lingual and fusiform gyri). Regions with higher sALFF had less Aβ accumulation. Correlated cluster sizes in MNI space (r ≈ -0.47) were reduced from 3018 mm3 to 1072 mm3 with stronger cardiovascular regression. These preliminary findings imply that local brain blood fluctuations due to vascular hemodynamics or neuronal activity can affect Aβ homeostasis.

Abstract
BACKGROUND Life expectancy (LE) following Alzheimer's disease (AD) is highly variable. The literature to date is limited by smaller sample sizes and clinical diagnoses. OBJECTIVE No study to date has evaluated predictors of AD LE in a retrospective large autopsy-confirmed sample, which was the primary objective of this study. METHODS Participants (≥50 years old) clinically and neuropathologically diagnosed with AD were evaluated using National Alzheimer's Coordinating Center (N = 1,401) data. Analyses focused on 21 demographic, medical, neuropsychiatric, neurological, functional, and global cognitive predictors of LE at AD dementia diagnosis. These 21 predictors were evaluated in univariate analyses. Variables found to be significant were then entered into a forward multiple regression. LE was defined as months between AD diagnosis and death. RESULTS Fourteen predictors were significant in univariate analyses and entered into the regression. Seven predictors explained 27% of LE variance in 764 total participants. Mini-Mental State Examination (MMSE) score was the strongest predictor of LE, followed by sex, age, race/ethnicity, neuropsychiatric symptoms, abnormal neurological exam results, and functional impairment ratings. Post-hoc analyses revealed correlations of LE were strongest with MMSE ≤12. CONCLUSION Global cognitive functioning was the strongest predictor of LE following diagnosis, and AD patients with severe impairment had the shortest LE. AD patients who are older, male, white, and have more motor symptoms, functional impairment, and neuropsychiatric symptoms were also more likely have shorter LE. While this model cannot provide individual prognoses, additional studies may focus on these variables to enhance predictions of LE in patients with AD.

Abstract
Few studies have examined an association between mild traumatic brain injury (mTBI) and Alzheimer's disease (AD). For this reason, we compared an AD dementia group with an mTBI history (n = 10) to a matched AD control group (n = 20) on measures of cognitive function, cerebral glucose metabolism, and markers of amyloid and tau deposition. Only a trend and medium-to-large effect size for higher phosphorylated and total tau was identified for the mTBI group. A history of mTBI may be associated with greater tau in AD, indicating a potential pathway for increasing risk for AD, though further evaluation with larger samples is needed.

Abstract
OBJECTIVE There is limited information regarding neurocognitive outcomes of right unilateral ultrabrief pulse width electroconvulsive therapy (RUL-UB ECT) combined with pharmacotherapy in older adults with major depressive disorder. We report longitudinal neurocognitive outcomes from Phase 2 of the Prolonging Remission in Depressed Elderly (PRIDE) study. METHOD After achieving remission with RUL-UB ECT and venlafaxine, older adults (≥60 years old) were randomized to receive symptom-titrated, algorithm-based longitudinal ECT (STABLE) plus pharmacotherapy (venlafaxine and lithium) or pharmacotherapy-only. A comprehensive neuropsychological battery was administered at baseline and throughout the 6-month treatment period. Statistical significance was defined as a p-value of less than 0.05 (two-sided test). RESULTS With the exception of processing speed, there was statistically significant improvement across most neurocognitive measures from baseline to 6-month follow-up. There were no significant differences between the two treatment groups at 6 months on measures of psychomotor processing speed, autobiographical memory consistency, short-term and long-term verbal memory, phonemic fluency, inhibition, and complex visual scanning and cognitive flexibility. CONCLUSION To our knowledge, this is the first report of neurocognitive outcomes over a 6-month period of an acute course of RUL-UB ECT followed by one of 2 strategies to prolong remission in older adults with major depression. Neurocognitive outcome did not differ between STABLE plus pharmacotherapy versus pharmacotherapy alone over the 6-month continuation treatment phase. These findings support the safety of RUL-UB ECT in combination with pharmacotherapy in the prolonging of remission in late-life depression.

Abstract
OBJECTIVE The purpose of this study was to assess cerebral blood flow (CBF) and its association with self-reported symptoms in chronic traumatic brain injury (TBI). PARTICIPANTS Sixteen participants with mild to severe TBI and persistent self-reported neurological symptoms, 6 to 72 months post-injury were included. For comparison, 16 age- and gender-matched healthy normal control participants were also included. MAIN MEASURES Regional CBF and brain volume were assessed using pseudo-continuous Arterial Spin Labeling (PCASL) and T1-weighted data respectively. Cognitive function and self-reported symptoms were assessed in TBI participants using the national institutes of health (NIH) Toolbox Cognition Battery and Patient-Reported Outcome Measurement Information System respectively. Associations between CBF and cognitive function, symptoms were assessed. RESULTS Global CBF and regional brain volumes were similar between groups, but region of interest (ROI) analysis revealed lower CBF bilaterally in the thalamus, hippocampus, left caudate, and left amygdala in the TBI group. Voxel-wise analysis revealed that CBF in the hippocampus, parahippocampus, rostral anterior cingulate, inferior frontal gyrus, and other temporal regions were negatively associated with self-reported anger, anxiety, and depression symptoms. Furthermore, region of interest (ROI) analysis revealed that hippocampal and rostral anterior cingulate CBF were negatively associated with symptoms of fatigue, anxiety, depression, and sleep issues. CONCLUSION Regional CBF deficit was observed in the group with chronic TBI compared to the normal control (NC) group despite similar volume of cerebral structures. The observed negative correlation between regional CBF and affective symptoms suggests that CBF-targeted intervention may potentially improve affective symptoms and quality of life after TBI, which needs to be assessed in future studies.

Abstract
PURPOSE In 2003, randomized trials demonstrated potentially improved outcomes when local instead of general anesthesia is used for inguinal hernia repair. Our study aimed to evaluate how the use of local anesthesia for this procedure changed over time following the publication of the trials' level 1 evidence. METHODS We used the 1998-2018 Veterans Affairs Surgical Quality Improvement Program database to identify adults who underwent open, unilateral inguinal hernia repair under local or general anesthesia. Our primary outcome was the percentage of cases performed under local anesthesia. We used a time-series design to examine the trend and rate of change of the use of local anesthesia. RESULTS We included 97,437 veterans, of which 22,333 (22.9%) had hernia surgery under local anesthesia. The median age of veterans receiving local anesthesia remained stable at 64-67 years over time. The use of local anesthesia decreased steadily, from 38.2% at the beginning year to 15.1% in the final year (P < 0.0001). The publication of results from randomized trials (in 2003) did not appear to increase the overall use or change the rate of decline in the use of local anesthesia. Overall, we found that the use of local anesthesia decreased by about 1.5% per year. CONCLUSION The utilization of local anesthesia for inguinal hernia repair in the VA has steadily declined over the last 20 + years, despite data showing equivalence or superiority to general anesthesia. Future studies should explore barriers to the use of local anesthesia for hernia repair.

Abstract
INTRODUCTION Recovery and return to play are important milestones for athletes who sustain sport-related concussions (SRC). Several factors have been shown to influence resolution of post-concussion related symptoms (PCS), but resilience, a trait that reflects the ability to overcome adversity, is another factor that may influence recovery. The aim of this study was to determine the relationship of resilience with resolution of symptoms during recovery in adolescents and young adults following SRC. METHOD This prospective study is part of the North Texas Concussion Registry (ConTex). Subjects (N = 332) aged 13 to 25 years who sustained a SRC within 10 days of presenting to clinic were evaluated at two time points: initial clinical visit and three-month follow-up. Resilience was measured by the self-report Brief Resilience Survey (BRS) and PCS by the Sport Concussion Assessment Tool-5 Symptom Evaluation Post-Concussion Symptom Scale (PCSS). Recovery was determined by self-reported return to sports/physical activity and percent back to normal. RESULTS Repeated measures ANCOVA and linear regression models showed that lower resilience ratings at initial visit were associated with a greater number and severity of PCSS symptoms along with higher levels of anxiety and depression symptoms during recovery from SRC. At three months, subjects with lower initial resilience ratings were less likely to report feeling back to normal and had greater aggravation of symptoms from physical and cognitive activity even when they had returned to sports/physical activity. CONCLUSIONS Lower resilience was associated with greater symptoms and delayed recovery from SRC. Results suggest that resilience may be another important factor to address in recovery from SRC. Future research is needed to examine the extent to which resilience measured after SRC reflects pre-injury characteristics and to better inform the development of interventions to promote resilience during recovery.

BACKGROUND Cerebral blood flow (CBF) is sensitive to changes in arterial CO2, referred to as cerebral vasomotor reactivity (CVMR). Whether CVMR is altered in patients with amnestic mild cognitive impairment (aMCI), a prodromal stage of Alzheimer disease (AD), is unclear. OBJECTIVE To determine whether CVMR is altered in aMCI and is associated with cognitive performance. METHODS Fifty-three aMCI patients aged 55 to 80 and 22 cognitively normal subjects (CN) of similar age, sex, and education underwent measurements of CBF velocity (CBFV) with transcranial Doppler and end-tidal CO2 (EtCO2) with capnography during hypocapnia (hyperventilation) and hypercapnia (rebreathing). Arterial pressure (BP) was measured to calculate cerebrovascular conductance (CVCi) to normalize the effect of changes in BP on CVMR assessment. Cognitive function was assessed with Mini-Mental State Examination (MMSE) and neuropsychological tests focused on memory (Logical Memory, California Verbal Learning Test) and executive function (Delis-Kaplan Executive Function Scale; DKEFS). RESULTS At rest, CBFV and MMSE did not differ between groups. CVMR was reduced by 13% in CBFV% and 21% in CVCi% during hypocapnia and increased by 22% in CBFV% and 20% in CVCi% during hypercapnia in aMCI when compared to CN (all p < 0.05). Logical Memory recall scores were positively correlated with hypocapnia (r = 0.283, r = 0.322, p < 0.05) and negatively correlated with hypercapnic CVMR measured in CVCi% (r = -0.347, r = -0.446, p < 0.01). Similar correlations were observed in D-KEFS Trail Making scores. CONCLUSION Altered CVMR in aMCI and its associations with cognitive performance suggests the presence of cerebrovascular dysfunction in older adults who have high risks for AD.

Abstract
BACKGROUND Central arterial stiffness and brain hypoperfusion are emerging risk factors of Alzheimer's disease (AD). Aerobic exercise training (AET) may improve central arterial stiffness and brain perfusion. OBJECTIVE To investigate the effects of AET on central arterial stiffness and cerebral blood flow (CBF) in patients with amnestic mild cognitive impairment (MCI), a prodromal stage of AD. METHODS This is a proof-of-concept, randomized controlled trial that assigned 70 amnestic MCI patients into a 12-month program of moderate-to-vigorous AET or stretching-and-toning (SAT) intervention. Carotid β-stiffness index and CBF were measured by color-coded duplex ultrasonography and applanation tonometry. Total CBF was measured as the sum of CBF from both the internal carotid and vertebral arteries, and divided by total brain tissue mass assessed with MRI to obtain normalized CBF (nCBF). Episodic memory and executive function were assessed using standard neuropsychological tests (CVLT-II and D-KEFS). Changes in cardiorespiratory fitness were measured by peak oxygen uptake (VO2peak). RESULTS Total 48 patients (29 in SAT and 19 in AET) were completed one-year training. AET improved VO2peak, decreased carotid β-stiffness index and CBF pulsatility, and increased nCBF. Changes in VO2peak were associated positively with changes in nCBF (r = 0.388, p = 0.034) and negatively with carotid β-stiffness index (r = -0.418, p = 0.007) and CBF pulsatility (r = -0.400, p = 0.014). Decreases in carotid β-stiffness were associated with increases in cerebral perfusion (r = -0.494, p = 0.003). AET effects on cognitive performance were minimal compared with SAT. CONCLUSION AET reduced central arterial stiffness and increased CBF which may precede its effects on neurocognitive function in patients with MCI.

Abstract
Abstract
Objective
Concussion symptoms are non-specific and various symptom inventories are influenced by sex, even in the absence of injury. The Texas Postconcussion Symptom Inventory (TPSI) is a new 66-item concussion-related symptom measure with three empirically-derived indices (Cognitive, Neuropsychiatric, and Somatic). We evaluated if symptom reporting on the TPSI related to sex in a large, mixed clinical sample.
Methods
A diverse clinical sample (N = 319, ages 17–92, M = 48.75), including patients with seizure disorders, dementias, and head injuries, completed the TPSI. Symptom reporting profiles between females (55%) and males (45%) were compared using profile analysis with age as a covariate.
Results
Although females (M = 20.62, 95% CI [18.91, 22.26]) and males (M = 19.14, 95% CI [17.32, 21.04]) endorsed higher scores on the Cognitive index (Possible Range = 0–52), no significant differences on symptom reporting patterns were seen between the groups on the Cognitive (p = 0.24) or Neuropsychiatric (p = 0.56) Indices. However, a significant difference was found on the Somatic index (Possible Range = 0–34), with females (M = 13.06, 95% CI [11.99, 13.94]) reporting higher scores [t(318) = 2.78, p < 0.01, partial η2 = 0.02] than males (M = 10.98, 95% CI [10.01, 12.17]).
Conclusions
In this preliminary study, results indicated sex differences in reporting concussion-associated symptoms on the TPSI across a variety of clinical conditions. Similar to prior studies, females reported more somatic symptoms yet were similar in their reports of Cognitive and Neuropsychiatric symptoms. Because baseline data is rarely available when evaluating concussions in clinical settings, future research aims are to develop normative data stratified by sex and investigate the utility of the TPSI within a concussion cohort.

Abstract
Our study aims were to identify the frequency of continued play following sport-related concussion (SRC), defined as continuing athletic activity on the same day following a suspected SRC, characteristics associated with continued play, and whether continued play was associated with worse outcomes. A prospective study of participants ages 13-18 years diagnosed with SRC at a pediatric sports medicine clinic over a 4-year period was conducted. A comparison was performed between athletes who reported continued play following SRC (PLAY) and those who did not (NO PLAY). Of 441 participants, 231 (52.4%) were in the PLAY group. The PLAY group recalled less severe balance problems from the day of injury (p = 0.02), but reported greater symptoms of trouble falling asleep, concentrating, and remembering at their initial clinic visit (p < 0.05). There was no difference in recovery time between groups. Greater symptom severity score at the initial clinic visit and longer time to presentation were associated with prolonged recovery in both groups (p < 0.01). In conclusion, more than half of the athletes in this sample continued to play on the same day following SRC. Our results indicate the need for a heightened focus on education and additional efforts to reduce continued play following SRC in adolescents.

Abstract
PURPOSE OF THE REVIEW Older adults with major depressive disorder are particularly vulnerable to MDD-associated adverse cognitive effects including slowed processing speed, decreased attention, and executive dysfunction. The purpose of this review is to describe the approach to a clinical neuropsychological evaluation in older adults with MDD. Specifically, this review compares and contrasts neurocognitive screening and clinical neuropsychological evaluation procedures and details the multiple components of the clinical neuropsychological evaluation. RECENT FINDINGS Research has shown that neurocognitive screening serves a useful purpose to provide an acute and rapid assessment of global cognitive function; however, it has limited sensitivity and specificity. The clinical neuropsychological evaluation process is multifaceted and encompasses a review of available medical records, neurobehavioral status and diagnostic interview, comprehensive cognitive and clinical assessment, examination of inclusion and diversity factors as well as symptom and performance validity, and therapeutic feedback. As such, the evaluation provides invaluable information on multiple cognitive functions, establishes brain and behavior relationships, clarifies neuropsychiatric diagnoses, and can inform the etiology of cognitive impairment. Clinical neuropsychological evaluation plays a unique and critical role in integrated healthcare for older adults with MDD. Indeed, the evaluation can serve as a nexus to synthesize information across healthcare providers in order to maximize measurement-based care that can optimize personalized medicine and overall health outcomes.
