Abstract
BACKGROUND Previous studies have examined the direct relationship between metamemory and memory performance in young and older adults, but the results of these studies have been inconsistent. Therefore, we examined whether metamemory mediates the effects of age on memory performance. METHODS We examined episodic memory and working memory through computerized tasks performed by a lifespan sample of 1554 healthy adults. Seven metamemory traits were measured with the Metamemory in Adulthood (MIA) questionnaire. Separate structural equation modeling analyses were conducted to investigate potential metamemory mediators that intervened between age and the accuracy and speed of accessing information from episodic and working memory. RESULTS The use of internal or external strategies mediated the effects of age on episodic memory and spatial working memory performance. The perception of one's own memory capacity and the experience of anxiety when using memory functions mediated the effects of age on working memory performance in both domains. CONCLUSIONS Metamemory traits have the power to strengthen or weaken the course of episodic and working memory decline throughout adulthood.

Subjective vs informant-reported cognitive complaints have differential clinical significance in covert cerebral small vessel disease. CEREBRAL CIRCULATION - COGNITION AND BEHAVIOR 2023; 5:100182. [PMID: 37745893 PMCID: PMC10514088 DOI: 10.1016/j.cccb.2023.100182] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Revised: 07/30/2023] [Accepted: 09/04/2023] [Indexed: 09/26/2023]
Abstract
Objective Subjective cognitive complaints are common in patients with cerebral small vessel disease (cSVD), yet their relationship with informant evaluations, objective cognitive functions and severity of brain changes are poorly understood. We studied the associations of subjective and informant reports with findings from comprehensive neuropsychological assessment and brain MRI. Method In the Helsinki SVD Study, 152 older adults with varying degrees of white matter hyperintensities (WMH) but without stroke or dementia were classified as having normal cognition or mild cognitive impairment (MCI) based on neuropsychological criteria. The measures also included continuous domain scores for memory and executive functions. Cognitive complaints were evaluated with the subjective and informant versions of the Prospective and Retrospective Memory Questionnaire (PRMQ) and Dysexecutive Questionnaire (DEX); functional abilities with the Amsterdam Instrumental Activities of Daily Living Questionnaire (A-IADL); and depressive symptoms with the Geriatric Depression Scale (GDS-15). Results Subjective cognitive complaints correlated significantly with informant reports (r=0.40-0.50, p<0.001). After controlling for demographics, subjective and informant DEX and PRMQ were not related to MCI, memory or executive functions. Instead, subjective DEX and PRMQ significantly associated with GDS-15 and informant DEX and PRMQ with WMH volume and A-IADL. Conclusions Neither subjective nor informant-reported cognitive complaints associated with objective cognitive performance. Informant-evaluations were related to functional impairment and more severe WMH, whereas subjective complaints only associated with mild depressive symptoms. These findings suggest that awareness of cognitive impairment may be limited in early-stage cSVD and highlight the value of informant assessments in the identification of patients with functional impairment.

Pai M, Lu W, Chen M, Xue B. The association between subjective cognitive decline and trajectories of objective cognitive decline: Do social relationships matter? Arch Gerontol Geriatr 2023; 111:104992. [PMID: 36934694 DOI: 10.1016/j.archger.2023.104992] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 03/05/2023] [Accepted: 03/05/2023] [Indexed: 03/10/2023]
Abstract
OBJECTIVES We examine the association between subjective cognitive decline (SCD) and the trajectories of objective cognitive decline (OCD); and the extent to which this association is moderated by social relationships. METHODS Data come from waves 10 (2010) through 14 (2018) of the Health and Retirement Study, a nationally representative panel survey of individuals aged 50 and above in the United States. OCD is measured using episodic memory, and overall cognition. SCD is assessed using a baseline measure of self-rated memory. Social relationships are measured by social network size and perceived positive and negative social support. Growth curve models estimate the longitudinal link between SCD and subsequent OCD trajectories and the interactions between SCD and social relationship variables on OCD. RESULTS SCD is associated with subsequent OCD. A wider social network and lower perceived negative support are linked to slower decline in memory, and overall cognition. None of the social relationship variables, however, moderate the link between SCD and future OCD. CONCLUSION Knowing that SCD is linked to subsequent OCD is useful because at SCD stage, deficits are more manageable relative to those at subsequent stages of OCD. Future work on SCD and OCD should consider additional dimensions of social relationships.

Abstract
Clinical neuropsychology has been a valuable asset to neurologic surgery, contributing to lateralization and localization of pathologic brain tissue, identification of eloquent cortex, and evaluation of postoperative neuropsychological functioning. Moreover, neuropsychologists provide empirically driven interventions aimed at supporting preparation and/or recovery of neurosurgery patients. Nonetheless, several challenges may limit the reliability, validity, and generalizability of the assessment data obtained and reduce the usefulness of other neuropsychological services provided. Specifically, linguistic, cultural, educational, and other biases associated with demographic characteristics can lead to a narrowed view of an individual's life experiences, which must be confronted to fulfill the mission of ensuring that all patients have access to care that is appropriate to their needs. Instead of perceiving these challenges as insurmountable barriers, such issues can be viewed as opportunities to catalyze change and foster innovation for the future of neuropsychological care in neurosurgical settings. In addition to reviewing the possible mechanisms of these obstacles, the current article offers tangible solutions at both a macro level (e.g., discipline-wide transformations) and micro level (e.g., individualized patient-centric approaches). Outlined are practical techniques to potentially improve consensus and standardization of methods, advance and globalize research, expand representativeness of measures and practices to serve diverse individuals, and increase treatment adherence through engagement of patients and their families.

Updated Review of the Evidence Supporting the Medical and Legal Use of NeuroQuant ® and NeuroGage ® in Patients With Traumatic Brain Injury. Front Hum Neurosci 2022; 16:715807.

Abstract
Over 40 years of research have shown that traumatic brain injury affects brain volume. However, technical and practical limitations made it difficult to detect brain volume abnormalities in patients suffering from chronic effects of mild or moderate traumatic brain injury. This situation improved in 2006 with the FDA clearance of NeuroQuant®, a commercially available, computer-automated software program for measuring MRI brain volume in human subjects. More recent strides were made with the introduction of NeuroGage®, commercially available software that is based on NeuroQuant® and extends its utility in several ways. Studies using these and similar methods have found that most patients with chronic mild or moderate traumatic brain injury have brain volume abnormalities, and several of these studies found-surprisingly-more abnormal enlargement than atrophy. More generally, 102 peer-reviewed studies have supported the reliability and validity of NeuroQuant® and NeuroGage®. Furthermore, this updated version of a previous review addresses whether NeuroQuant® and NeuroGage® meet the Daubert standard for admissibility in court. It concludes that NeuroQuant® and NeuroGage® meet the Daubert standard based on their reliability, validity, and objectivity. Due to the improvements in technology over the years, these brain volumetric techniques are practical and readily available for clinical or forensic use, and thus they are important tools for detecting signs of brain injury.

Abstract
Despite the importance of capturing problems with judgment and decision-making during neuropsychological evaluations of older adults, there are a limited number of validated measures and no informant rating scales. We developed an informant measure that captures compromised judgment related to safety, medical, financial, and social-ethical issues After item refinement and piloting in a memory disorders clinic, we utilized the Test of Practical Judgment-Informant (TOP-J-Informant) at two clinics in the Midwestern U.S., including 189 patient/informant dyads (mean age = 79.0, median years of education = 13, % female = 67.7) with various preclinical and clinical dementia conditions. We found psychometric support, including evidence for convergent, divergent, and criterion-related validity, and internal consistency. Importantly, we were able to discriminate between diagnostic groups in the expected direction. The TOP-J-Informant is brief (<5 minutes), easy to administer, and can reveal areas of concern related to poor judgment when administered in the context of a neuropsychological evaluation or clinic visit.

Abstract
The ability of remote research tools to collect granular, high-frequency data on symptoms and digital biomarkers is an important strength because it circumvents many limitations of traditional clinical trials and improves the ability to capture clinically relevant data. This approach allows researchers to capture more robust baselines and derive novel phenotypes for improved precision in diagnosis and accuracy in outcomes. The process for developing these tools however is complex because data need to be collected at a frequency that is meaningful but not burdensome for the participant or patient. Furthermore, traditional techniques, which rely on fixed conditions to validate assessments, may be inappropriate for validating tools that are designed to capture data under flexible conditions. This paper discusses the process for determining whether a digital assessment is suitable for remote research and offers suggestions on how to validate these novel tools.

Abstract
BACKGROUND Despite the current evidence of a high prevalence of forgetfulness in middle-aged individuals, and the evidence of a link between midlife memory complaints and biological changes in the brain, no previous study has yet investigated midlife forgetfulness in relation to risk of dementia in old age. AIMS We investigated whether midlife forgetfulness was an indicator of an increased risk of dementia in old age. METHODS We used data from 3,136 employed men and women who participated in the Danish Work Environment Cohort Study in 1990. These data were linked to Danish national registers. Participants were asked whether their closest relative had ever told them that they were forgetful. Incidence rate ratios (IRR) were estimated using Poisson regression analysis. RESULTS At baseline, 749 (24%) study participants were categorized as forgetful, and 86 (2.7%) participants were diagnosed with dementia during a total of 31,724 person-years at risk. After adjusting for sociodemographic factors, comorbidities, and work-related factors, midlife forgetfulness was associated with a higher risk of dementia (IRR = 1.82; 95% CI: 1.12-2.97). CONCLUSIONS This study is the first to investigate midlife forgetfulness and dementia, and the results suggest that midlife forgetfulness is an early indicator of an increased risk of dementia in old age.

Abstract
BACKGROUND Subjective memory complaints (SMCs) are incorporated into the diagnosis of mild cognitive impairment (MCI) and neurodegenerative dementias; however, the relative frequency of SMCs in cognitively intact older adults and those with different types of dementia is poorly understood. Similarly, the concordance between self- versus informant-reported SMCs has not been compared across different diagnostic groups. OBJECTIVE This study aimed to evaluate the frequency of self-reported (Objective 1) and informant-reported (Objective 2) SMCs in cognitively intact adults or those diagnosed with MCI or a neurodegenerative dementia. Agreement between participant and informant complaints was also evaluated (Objective 3). METHODS Baseline evaluation data were drawn from 488 participants (Mage = 70.49 years; Medu = 15.62 years) diagnosed as cognitively intact, non-amnestic MCI, amnestic single domain MCI, amnestic multi-domain MCI, possible/probable Alzheimer's disease, dementia with Lewy bodies, or frontotemporal dementia. Participants and their informants completed the Memory Assessment Clinic Questionnaire. RESULTS One-way ANCOVAs controlling for age, education, and depression revealed no group differences in severity of self-reported SMCs. In contrast, informant memory ratings followed the expected clinical pattern, with comparable and most impaired ratings given to participants with any dementia diagnosis, followed by those with any MCI diagnosis, followed by cognitively intact participants. There was inconsistent agreement between self- and informant-reported SMC ratings in any of the impaired groups. CONCLUSIONS Given greater diagnostic specificity and internal consistency of informant report, clinicians should weigh this information more heavily than self-report in the diagnostic process.

Abstract
AIM The present population-based study investigated the predictive ability of the Kihon Checklist (a self-reported frailty questionnaire) and the cognitive domain therein for incident long-term care need certification. This is the first large population-based study to investigate an association between the Kihon Checklist and the outcome measure, long-term care need certification. METHODS The study population consisted of community-dwelling citizens aged >65 years who responded to the Kihon Checklist in Kobe City. The Kihon Checklist is a simple 26-item questionnaire to identify frail citizens, including three items (Q18-20) on subjective cognitive function (the cognitive domain). RESULTS A total of 182 099 citizens were included for statistical analysis. The overall incidence of long-term care need certification was 1.6%, 3.5% and 5.4% at 1, 2 and 3 years. Associations were found between the Kihon Checklist questions and long-term care need certification. Furthermore, each unfavorable answer on the cognitive domain was associated with the risk for long-term care need (HR 1.493 for Q18, 1.285 for Q19, 1.321 for Q20, all P < 0.0001), independent of age, sex and other items on the Kihon Checklist. Also, after 3 years, as the number of unfavorable answers to the cognitive domain increased from 0 to 1, 2 and 3, the incidence of long-term care need certification progressively increased from 3.5% to 6.4%, 12.6% and 29.6%. CONCLUSIONS The Kihon Checklist, especially the cognitive domain therein, appears to be predictive of long-term care need in community-dwelling citizens, suggesting the potential utility of the questionnaire for early detection of high-risk individuals.

Abstract
BackgroundSubjective cognitive decline (SCD) is the sense of deterioration in cognitive functioning in terms of memory, executive function, attention, etc. SCD is reported by nearly 70% of the population. Very intensive research on the predictive role of SCD in the development of dementia and determinants SCD did not bring common solutions. For exploration of the phenomenon, studies were undertaken in order to identify: a) on the basis of which factors a high level of SCD can be predicted, and b) whether these factors have similar prognostic value for two types of SCD, i.e. concerning executive function (SED) and memory (SMD).Participants and procedureThe study involved 274 Polish people aged 18 to 84 years (M = 53.23, SD = 16.8). For the evaluation of SCD three methods were used: memory self-assessment scales (ProCog and MARS), and an executive functions self-assessment scale (DEX-S). Subtests of the WAIS-PL to assess cognitive function were used, and GDS-15 or BECK II to assess the severity of depressive mood. In the first stage, two separate cluster analyses (k-means method) were performed: the first related to the results of the memory self-assessment scale (ProCog and MARS), the second to the subjective difficulty of executive functions (DEX-S). In step II a logistic regression analysis of the forward selection with the likelihood ratio and interaction effects was performed – separately for the two types of self-reports.ResultsThe results indicate that higher depressed mood increases the likelihood of both the SMD and SED. Higher efficiency attention-al processes reduce the possibility of formulating the SED, and higher efficiency of the delayed memory, abstract thinking, or certain aspects of language functions reduces the possibility of SMD.ConclusionsThere are two independent mechanisms of SCD – emotional and cognitive.

Abstract
This study examines (1) whether subjective memory problems (SMP) influence perceived emotional support from and frequency of contact with family and friends; and, (2) the extent to which this relationship is moderated by gender, education, and functional limitations. We use the 2014 wave of the Health and Retirement Study, a nationally representative panel survey of adults aged 51 and over in the United States. While SMP does not affect perceived emotional support for younger group (YG; aged 51-64), in older group (OG; aged 65+), SMP is associated with reduced perceived support from friends. Also, SMP is predictive of fewer writing-based contact with children and friends among OG but not among YG. Lastly, we find that the effect of SMP on support from children is contingent upon activity of daily living (YG) and gender (OG), while the effect of SMP on writing-based contact with both children and friends is contingent upon education (YG only).

Abstract
OBJECTIVES Although subjective cognitive complaints (SCC) are an integral component of the diagnostic criteria for mild cognitive impairment (MCI), previous findings indicate they may not accurately reflect cognitive ability. Within the Alzheimer's Disease Neuroimaging Initiative, we investigated longitudinal change in the discrepancy between self- and informant-reported SCC across empirically derived subtypes of MCI and normal control (NC) participants. METHODS Data were obtained for 353 MCI participants and 122 "robust" NC participants. Participants were classified into three subtypes at baseline via cluster analysis: amnestic MCI, mixed MCI, and cluster-derived normal (CDN), a presumptive false-positive group who performed within normal limits on neuropsychological testing. SCC at baseline and two annual follow-up visits were assessed via the Everyday Cognition Questionnaire (ECog), and discrepancy scores between self- and informant-report were calculated. Analysis of change was conducted using analysis of covariance. RESULTS The amnestic and mixed MCI subtypes demonstrated increasing ECog discrepancy scores over time. This was driven by an increase in informant-reported SCC, which corresponded to participants' objective cognitive decline, despite stable self-reported SCC. Increasing unawareness was associated with cerebrospinal fluid Alzheimer's disease biomarker positivity and progression to Alzheimer's disease. In contrast, CDN and NC groups over-reported cognitive difficulty and demonstrated normal cognition at all time points. CONCLUSIONS MCI participants' discrepancy scores indicate progressive underappreciation of their evolving cognitive deficits. Consistent over-reporting in the CDN and NC groups despite normal objective cognition suggests that self-reported SCC do not predict impending cognitive decline. Results demonstrate that self-reported SCC become increasingly misleading as objective cognitive impairment becomes more pronounced. (JINS, 2018, 24, 842-853).

Abstract
BACKGROUND Increased stride time variability has been associated with memory impairment in mild cognitive impairment. Subjective memory impairment (SMI) is considered the earliest clinical stage of Alzheimer's disease (AD). The association between increased stride time variability and SMI has not been reported. OBJECTIVE This study aims to examine the association of stride time variability while performing single and dual tasking with SMI in cognitively healthy individuals (CHI). METHODS A total of 126 CHI (15 without SMI, 69 with SMI expressed by participants, 10 with SMI expressed by participant's relative, and 32 with SMI expressed by both participants and their relatives) were included in this cross-sectional study. The coefficient of variation (CoV) of stride time and walking speed were recorded under usual condition and while counting backwards. Age, gender, body mass index, number of drugs taken daily, use of psychoactive drugs, fear of falling, history of previous falls, and walking speed were used as covariates. RESULTS The multiple linear regression models showed that greater CoV of stride time while counting backwards, but not while single tasking, was associated with a participant's relative SMI (p = 0.038). CONCLUSION This study found a specific association between SMI expressed by a participant's relative and a greater CoV of stride time (i.e., worse performance) while dual tasking, suggesting that the association between gait variability and memory may be present in the earliest stages of memory impairment. Thus, gait variability under dual-task in individuals with SMI expressed by their relatives can be a potential biomarker of AD.

Abstract
OBJECTIVE The last 25 years have seen profound changes in neurocognitive rehabilitation that continue to motivate its evolution. Although the concept of nervous system plasticity was discussed by William James (1890), the foundation for experience-based plasticity had not reached the critical empirical mass to seriously impact rehabilitation research until after 1992. The objective of this review is to describe how the emergence of neural plasticity has changed neurocognitive rehabilitation research. METHOD The important developments included (a) introduction of a widely available tool that could measure brain plasticity (i.e., functional MRI); (b) development of new structural imaging techniques that could define limits of and opportunities for neural plasticity; (c) deployment of noninvasive brain stimulation to leverage neural plasticity for rehabilitation; (d) growth of a literature indicating that exercise has positively impacts neural plasticity, especially for older persons; and (e) enhancement of neural plasticity by creating interventions that generalize beyond the boundaries of treatment activities. Given the massive literature, each of these areas is developed by example. RESULTS The expanding influence of neural plasticity has provided new models and tools for neurocognitive rehabilitation in neural injuries and disorders, as well as methods for measuring neural plasticity and predicting its limits and opportunities. Early clinical trials have provided very encouraging results. CONCLUSION Now that neural plasticity has gained a firm foothold, it will continue to influence the evolution of neurocognitive rehabilitation research for the next 25 years and advance rehabilitation for neural injuries and disease.

Abstract
OBJECTIVE The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) has been used extensively for clinical care and in research for patients with mild cognitive impairment and Alzheimer's disease (AD); however, relatively few studies have evaluated the relationship between RBANS performance and AD imaging biomarkers. The purpose of the current study was to evaluate the association between a relatively new amyloid positron emission tomography imaging biomarker and performance on the RBANS. METHODS Twenty-seven nondemented community-dwelling adults over the age of 65 underwent 18F-Flutemetamol amyloid- positron emission tomography imaging, along with cognitive testing using the RBANS and select behavioral measures. Partial correlation coefficients were used to identify relationships between the imaging and behavioral markers. RESULTS After controlling for age and education, amyloid deposition and RBANS Indexes of Immediate Memory, Delayed Memory, and Total Scale score were significantly correlated (p's < .001, r's = -.73 to -.77, d's = 2.13-2.39), with greater amyloid burden being associated with lower RBANS scores. The Delayed Memory Index was particularly highly associated with 18F-Flutemetamol binding (r2 = .59, p < .001, d = 2.39). Neither 18F-Flutemetamol binding nor RBANS performance was significantly correlated with levels of depression, subjective cognitive difficulties, or premorbid intellect. CONCLUSIONS Because of the limited use of amyloid imaging in clinical settings due to high cost and lack of reimbursement, these findings suggest that in particular RBANS Delayed Memory Index may be a cost-efficient tool to identify early signs of AD pathology, and its use may enlighten clinical decision-making regarding potential progression to dementia due to AD.

Abstract
Introduction In patients with Alzheimer's disease (AD) and mild cognitive impairment, structural changes in the retina (i.e., reduced thicknesses of the ganglion cell and retinal nerve fiber layers and inclusion bodies that appear to contain beta-amyloid protein [Ab]) have been previously reported. We sought to explore whether anatomic retinal changes are detectable in the preclinical stage of AD. Methods A cross-sectional study (as part of an ongoing longitudinal cohort study) involving 63 cognitively normal adults, all of whom have a parent with AD and subjective memory complaints. We compared neocortical amyloid aggregation (florbetapir PET imaging) to retinal spectral domain optical coherence tomography (SD-OCT) markers of possible disease burden. Retinal biomarkers, including the number and surface area of retinal inclusion bodies and the thickness of retinal neuronal layers, were compared across groups with high vs. low neocortical beta-amyloid load. Results The surface area of inclusion bodies increased as a function of cortical amyloid burden. Additionally, there was a trend toward a selective volume increase in the inner plexiform layer (IPL; a layer rich in cholinergic activity) of the retina in Aβ+ relative to Aβ− participants, and IPL volume was correlated with the surface area of retinal inclusion bodies. Discussion These initial results suggest that retinal imaging may be a potential cost-effective and noninvasive technique that can be used to identify those at-risk for AD. Layer-specific changes in the IPL and their association with surface area of inclusion bodies are discussed as a possible reflection of early inflammatory processes associated with cholinergic disruption and concurrent Ab accumulation in the neocortex.

Abstract
O traumatismo cranioencefálico (TCE) pode acarretar mudanças no cotidiano e prejuízos social laboral comunicativo e cognitivo (dificuldades atencionais mnemônicas e executivas). Este estudo buscou caracterizar a ocorrência de déficits neuropsicológicos após o TCE em uma amostra de adultos e verificar se há impacto do nível de severidade do trauma no desempenho cognitivo dos pacientes. Participaram 96 adultos divididos em dois grupos: TCE leve (n=39) e grave (n=57). A gravidade do trauma foi classificada pela Escala de Coma de Glasgow pela duração da perda de consciência. ou pela amnésia pós-traumática. Não houve diferença nas variáveis sociodemográficas idade e escolaridade entre os grupos. Para a comparação entre grupos quanto a ocorrência de déficits neuropsicológicos. utilizou-se o Qui-quadrado. Tarefas verbais e visuoespaciais de funções executivas habilidades linguísticas. mnemônicas verbais compuseram uma bateria neuropsicológica flexível.Os pacientes com TCE leve tiveram menos déficits comparados aos com TCE grave (erros e categorias completadas do Wisconsin Teste de Classificação de Cartas; erros da parte B do Teste Hayling; e na interferência pró e retroativa do teste de aprendizagem verbal de Rey). A severidade do trauma parece diferenciar indivíduos no desempenho de memória episódica no contexto de maior sobrecarga de informações novas e no controle da interferência entre memórias; o mesmo se aplica às funções de flexibilidade e inibição. Fazse necessário um maior investimento em ações de políticas públicas de saúde priorizando intervenção neurognitiva remediativa e métodos de prevenção para acidentes relacionados a lesões traumáticas com alta ocorrência de sequelas.

Abstract
INTRODUCTION Three (18)F-labeled radiopharmaceuticals have been Food and Drug Administration-approved for the identification of cortical amyloidosis in clinical settings. Although there has been strong debate among professionals as to the ethical and social consequences of disclosing such information, increasing numbers of participants are being recruited into secondary prevention trials for which they are likely to, and/or desire to, receive their positron emission tomography (PET) imaging results. METHODS Healthy older adults (n = 63, mean age = 62 years) enrolled in a preclinical Alzheimer's disease (AD) biomarkers trial, and 11 requested disclosure of PET amyloid imaging results to their treating neurologist, per institutional review board-approved study protocol. These individuals completed a follow-up psychoeducational program and structured interviews to assess impact of disclosure on several key psychological factors. RESULTS Four of 11 subjects demonstrated increased amyloid aggregation and reported that they were not surprised, particularly given their family histories and subjective memory concerns. All indicated that they had shared this information with pertinent significant others; they were satisfied with their level of social support, and the imaging results had motivated them to change their lifestyle by exercising more, changing their diet, and planning ahead. Amyloid-positive participants showed little change in levels of depressive, anxiety, and stress symptoms, subjective sense of memory impairment, or on measures of intrusion, avoidance, and hyperarousal, and reported risk of self-harm. DISCUSSION Disclosure of PET amyloid status did not significantly impact mood, subjective sense of memory impairment, or perceived risk of developing AD; nor was this associated with significant emotional impact, irrespective of actual amyloid burden status. Those subjects with increased amyloid burden were more likely than those without significant amyloidosis to make positive changes to their lifestyle (e.g., engaging in more exercise and changing their diet).
