Abstract
The current project examined sleep, sleep/wake regularity, and cognition in college students diagnosed with depression and using serotonergic antidepressants and in those without a depression diagnosis. Forty participants either using antidepressants (n = 20, 24.75 ± 6.82 years) or without a depression diagnosis (n = 20, 21.70 ± 2.74 years) wore actigraphs for two consecutive weeks (14 days). Cognitive tasks were completed on day 1 (along with demographic surveys) and day 14. Effect sizes indicated that compared to non-clinically depressed peers, participants using antidepressants exhibited slightly greater wake after sleep onset (d = 0.36) and lower sleep efficiency (d = 0.40); however, these differences were likely not noticed by the sleeper. No sleep regularity or cognitive differences were present between groups. Within the antidepressant group, higher dosage predicted greater time in bed (R2 = 0.77), but less total sleep time (R2 = 0.86). The time of day that participants took their antidepressant exhibited differential effects on certain cognitive parameters, such as procedural reaction time and spatial processing, and interactions with years of antidepressant use were found. Self-reported wake episodes also predicted better reaction time and inhibition in the antidepressant group. This study is the first to demonstrate that sleep/wake regularity is comparable between people using antidepressants and non-clinically depressed human samples. For individuals using antidepressants, years of use, dosage, and time of day of use have predictive qualities for reaction times, spatial processing, and inhibition.

Case study of invalid to valid shift in cognitive performance following successful treatment of psychogenic nonepileptic seizure events. J Clin Exp Neuropsychol 2023; 45:1024-1038. [PMID: 38533868 DOI: 10.1080/13803395.2024.2335600] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2023] [Accepted: 02/06/2024] [Indexed: 03/28/2024]
Abstract
Patients with psychogenic nonepileptic seizure (PNES) who fail performance validity testing (PVT) may appear to produce non-valid cognitive profiles. Consequently, they may not get referred to treatment and events persist, with worsening disability and high resource utilization. As a result, we report pre- and post-treatment neuropsychological evaluation findings in a 59-year-old woman with a confirmed diagnosis of PNES established using video-EEG monitoring. At pre-treatment baseline neuropsychological evaluation, PNES events occurred weekly to daily. Performance was impaired across PVTs and across multiple cognitive domains. After behavioral intervention specific to PNES, these events substantially reduced in frequency to rare stress-induced flares. Post-treatment neuropsychological evaluation revealed marked improvement of most cognitive and behavioral scores from baseline, and valid PVT scores. We review predisposing, precipitating, and perpetuating factors for PNES and cognitive impairment in this case and discuss the patient's outcome from treatment. Effectively managing PNES events and dissociative tendencies while reducing unnecessary pharmacological interventions appears to have allowed this patient to function closer to her optimal state. This case illustrates the complexity of Functional Neurologic Disorder (FND) clinical presentation and challenges the assumption that suboptimal neuropsychological performance predicts poor treatment engagement and outcome. We showcase the reversibility of PNES and cognitive manifestations of FND using targeted psychotherapeutic interventions, which resulted in reduced disability and associated healthcare costs, as well as re-engagement in life.

J Affect Disord 2023; 322:258-266. [PMID: 36370912 DOI: 10.1016/j.jad.2022.11.016] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2022] [Revised: 09/08/2022] [Accepted: 11/06/2022] [Indexed: 11/10/2022]
Abstract
BACKGROUND Peripheral cytokines were found to be involved in the pathophysiology of neurocognition in individuals with major depressive disorder (MDD). However, whether there are sex differences in this association between cytokines and cognition in MDD remains unknown. Our aim is to examine sex differences in the relationship between plasma cytokines and cognition in MDD. METHOD One hundred and twenty-seven first episode drug naïve patients with MDD and sixty healthy controls (HCs) were recruited for present study. The MATRICS Consensus Cognitive Battery was administered to measure the cognition. Plasma concentrations of nineteen cytokines were measured using high sensitivity multiplex bead-based assays. RESULTS Both female and male patients with MDD had significant cognitive impairment in verbal learning and visual learning and had higher levels of a range of cytokines than HCs (all p < 0.05). Female patients performed worse in trail making (F = 4.442, p = 0.018) and had higher concentration of interleukin (IL)-4 (F = 7.775, p = 0.006) than males. In female MDD, a significant positive association between category frequency and level of IL-4 was observed (B = 8.040, p = 0.031). However, this association was not present in male MDD or HCs (p > 0.05). LIMITATION Present study used a cross-sectional design. CONCLUSION Female MDD patients had worse trail making performance and higher level of IL-4 than males. The elevated IL-4 in female MDD was positively associated with category fluency, suggesting that IL-4 may be involved in the pathophysiology related to specific cognitive domain in female MDD patients.

Ethanol and Medical Psychotropics Co-Consumption in European Countries: Results from a Three-Year Retrospective Study of Forensic Samples in Spain. TOXICS 2022; 11:toxics11010045. [PMID: 36668771 PMCID: PMC9862312 DOI: 10.3390/toxics11010045] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Revised: 12/13/2022] [Accepted: 12/28/2022] [Indexed: 05/14/2023]
Abstract
Ethanol and medical psychotropics (MPs) are legal psychoactive substances widely consumed in Western countries that are routinely detected in standard toxicological analyses at compulsory autopsies, and toxicokinetic interactions between these drugs have been described. However, studies assessing the consequences of this co-consumption are scarce in Europe. We performed a retrospective study on toxicological results from compulsory autopsies in Spain. Thirty-five legal psychotropics, including ethanol, were measured in blood samples from 380 decedents to assess the determinants of such co-consumption. MPs were detected in 42.4% of the subjects. Polypharmacy was frequent in our series (25%), being more frequent in men than in women. More than one-third of the decedents had detectable levels of ethanol, and a significant positive association between ethanol levels and age was evident. About one-third of MPs consumers were also co-consumers of ethanol. The simultaneous consumption of ethanol and MPs was higher in men than in women. Blood alcohol concentrations (BAC) were lower in men who consumed MPs. In polypharmacy deaths, there was a significant negative association between the number of MPs consumed and BAC in men (r = -0.097; p = 0.029). Our results showed a high prevalence of co-consumption of MPs and ethanol in the European population involved in medico-legal issues and suggest that toxicokinetic interactions may be lowering BAC in men. This is a very worrying result, as it could indicate that the legal blood ethanol limits set by legislation would not be appropriate for men on MPs treatment.

Abstract
BACKGROUND Electroconvulsive therapy (ECT) is an effective treatment for depression, mania, and refractory schizophrenia. Its tolerability profile is established for acute treatment, but less is known regarding the effects of longer treatment courses, particularly on cognitive performance. OBJECTIVES To assess the effect of the long-term ECT on cognition. METHODS We searched CINAHL, EMBASE, PsychInfo and Pubmed, for the period between January 1, 2010, and June 30, 2022, in English or French, for randomized controlled trials, prospective or retrospective studies of ECT continued for at least 2 months for the treatment of mood or schizophrenic disorders and which measured cognition before and at the end of treatment. Non-peer reviewed records were excluded. The Cochrane Risk of Bias tool was used to assess study quality. Classical meta-analyses, with heterogeneity statistics (tau2, I2) were complemented with three level-meta-analysis and Bayesian Meta-analyses. RESULTS Nine studies were included in the narrative and quantitative review. Controlled comparison at 6 months (k = 6, n = 334) and at 12 months (k = 3, n = 56), within-subject comparisons at 6 (k = 6, n = 218) and 12 months (k = 4, n = 147) showed no detrimental effect of maintenance or continuation ECT on cognition, with little to no heterogeneity. Bayesian analysis further confirmed that data better supported the no effects hypothesis. LIMITATIONS Insufficient data resulted in imprecision in estimates. CONCLUSIONS Continuation and maintenance ECT do not appear detrimental for cognitive performance. However, the low number of studies limit the interpretation of the results.

Abstract
Objective diagnosis and prognosis in major depressive disorder (MDD) remains a challenge due to the absence of biomarkers based on physiological parameters or medical tests. Numerous studies have been conducted to identify functional magnetic resonance imaging‐based biomarkers of depression that either objectively differentiate patients with depression from healthy subjects, predict personalized treatment outcome, or characterize biological subtypes of depression. While there are some findings of consistent functional biomarkers, there is still lack of robust data acquisition and analysis methodology. According to current findings, primarily, the anterior cingulate cortex, prefrontal cortex, and default mode network play a crucial role in MDD. Yet, there are also less consistent results and the involvement of other regions or networks remains ambiguous. We further discuss image acquisition, processing, and analysis limitations that might underlie these inconsistencies. Finally, the current review aims to address and discuss possible remedies and future opportunities that could improve the search for consistent functional imaging biomarkers of depression. Novel acquisition techniques, such as multiband and multiecho imaging, and neural network‐based cleaning approaches can enhance the signal quality in limbic and frontal regions. More comprehensive analyses, such as directed or dynamic functional features or the identification of biological depression subtypes, can improve objective diagnosis or treatment outcome prediction and mitigate the heterogeneity of MDD. Overall, these improvements in functional MRI imaging techniques, processing, and analysis could advance the search for biomarkers and ultimately aid patients with MDD and their treatment course.

Abstract
Medical psychotropics are widely used and prescribed in developed countries. These medications may have an impairing effect on mood or perception and may induce harmful behaviors. Nevertheless, in Europe, studies on their importance from a medico-legal perspective are scarce. To fill this gap, we evaluate the determinants of these drugs in a retrospective study based on data obtained from forensic autopsies. Toxicological analyses were performed on 394 blood samples from compulsory autopsies at the Institute of Legal Medicine of Las Palmas. Of the samples, 41% (159) were positive for at least one psychotropic, with benzodiazepines being the most frequently detected (24.1%), followed by opiates and antidepressants. Benzodiazepines, opiates, and antidepressants were detected more frequently in men who suffered a violent death. More than 30% of the positive samples showed two or more drugs, suggesting a prevalence of polypharmacy among forensic autopsy subjects, with the most frequently combination found being benzodiazepines plus opiates (28.3% of positive samples). A combination of opiates plus antidepressants was also found in subjects involved in violent deaths. Our results suggest that more than 40% of the adult European population involved in medico-legal issues may be under the influence of legal psychotropics. The link between violent deaths and the use of medical psychotropics is particularly worrisome and indicates that these drugs should be carefully monitored in developed countries, in all forensic autopsies, in a similar way to illegal psychotropics.

Abstract
INTRODUCTION Neurocognitive tests are an integral component of sport-related concussion (SRC) workup. A history of psychiatric illness (HPI) is common among young athletes. Investigations of factors that influence athletes' baseline neurocognitive function are crucial for an accurate assessment of SRC. OBJECTIVE In this study, we aim to elucidate the effect of HPI and selective-serotonin reuptake inhibitor (SSRI) medication use on baseline neurocognitive performance in young athletes. METHODS We conducted a retrospective cross-sectional study of Immediate Post-Concussion Assessment and Cognitive Testing assessments. A total of 268 athletes with HPI and a control group of 6,364 athletes were included. The outcomes were total symptom score based on post-concussion symptom scale, verbal memory, visual memory, visual motor, reaction time, and impulse control scores with self-reported HPI status and SSRI use. RESULTS Athletes with HPI had an elevated symptom score in both univariate analysis (p < .0001) and multivariate analysis (p < .0001). HPI influence on visual memory score was not robust to multivariate analysis (p = .24). Athletes with HPI who reported SSRI medication use had the same baseline neurocognitive performance as other athletes with HPI. HPI influences athletes' baseline neurocognitive performance by elevating symptom scores. HPI does not alter any of the objective neurocognitive composite scores in contrast to previous work. CONCLUSIONS Clinicians should consider the impact of HPI on baseline neurocognitive performance during the assessment of a suspected SRC. Additional research is required to bolster our findings on SSRI use and ascertain the effects of other drug classes on baseline neurocognitive performance.

Abstract
Evidence suggests that psychopathic individuals display difficulties to adapt their behavior in accordance with the demands of the environment and show altered performance monitoring. Studies investigating the error-related negativity (ERN) and the error-positivity (Pe) as electrophysiological markers of error monitoring reported contradictory results for this population. To explain these discrepancies, we hypothesized that psychopathy dimensions influence electrophysiological outcomes. We predicted that individuals with impulsive-antisocial features would display abnormal ERN compared to individuals with interpersonal-affective features. A systematic review and meta-analysis of studies investigating ERN and Pe components were conducted. A factorial analysis was undertaken to investigate the role of psychopathy dimensions on ERN and Pe. Compared to controls, psychopathic individuals (n = 940) showed a reduced ERN and Pe amplitude. The factorial analysis indicates a dissociation regarding the construct of psychopathy. The models reported that psychopathic individuals related specifically to the interpersonal-affective dimension displayed normal ERN component and efficient error-monitoring, while psychopathic individuals with a marked impulsive-antisocial dimension display a decreased ERN component and altered performance monitoring.

Abstract
Background: Major depression is a psychiatric disorder characterized neuropsychologically by poor performance in tasks of memory, attention, processing speed, and executive function. The aim of this systematic review was to examine the evidence regarding the neuropsychological profile of people with major depression and to determine which of two explanatory models—the processing speed hypothesis or the cognitive effort hypothesis—has most empirical support. Methods: We searched three relevant databases and reviewed the reference lists of the articles retrieved. The results obtained with the Trail Making Test and the Stroop Color-Word Test were reviewed for 37 studies published between 1993 and 2020. Results: The empirical evidence supports both hypotheses: cognitive effort and processing speed, suggesting that depression is not only characterized by psychomotor slowing but also involves a specific deficit in executive function. Discussion: We discuss potentially relevant variables that should be considered in future research in order to improve knowledge about the neurocognitive profile of depression. The main limitation of this study derives from the considerable heterogeneity of participants with MD, which makes it difficult to compare and integrate the data.

Abstract
Background Treatment of pituitary pathology mostly does not result in complete recovery of impairment in cognitive functioning. The primary aim of the current study was to assess cognitive impairment in patients with stable replacement therapy for hypopituitarism during the last 6 months prior to inclusion. It was expected that patients showed subjective and objective subnormal scores on neuropsychological functioning. Methods Forty-two patients (40% men, 49 ± 15 years) treated for hypopituitarism conducted a neuropsychological test battery, including the Cognitive Failures Questionnaire (CFQ), 15-Word test (15-WT), Cambridge Neuropsychological Test Automated Battery (CANTAB) Motor Screening Task (MOT), Spatial Working Memory (SWM) and Affective Go/No-go (AGN). Results were compared to reference values of healthy norm groups. Results Male and female participants scored significantly worse on the CFQ (P < .01, d = 0.91-4.09) and AGN mean correct latency (P < .01, d = 1.66 and 1.29, respectively). Female participants scored significantly worse on 15-WT direct recall (P = .01, d = 0.66), 15-WT delayed recall (P = .01, d = 0.79), SWM total errors (P = .05, d = 0.41), SWM strategy (P = .04, d = 0.43), AGN errors of commission (P = .02, d = 0.56) and omission (P = .04, d = 0.41). Conclusion This study shows that subjective cognitive functioning is worse in patients treated for hypopituitarism compared to reference data. Also, female participants treated for hypopituitarism score worse on objective aspects of memory and executive functioning compared to reference data. Besides worse focus attention, this objective cognitive impairment was not found in male participants. It is recommended to conduct additional research, which focuses on the design and evaluation of a cognitive remediation therapy, aimed at compensation of impairments in different aspects of memory and executive functioning.

Neuropsychiatric Symptoms Exacerbate the Cognitive Impairments in Patients With Late-Life Depression. Front Psychiatry 2021; 12:757003. [PMID: 34867543 PMCID: PMC8639522 DOI: 10.3389/fpsyt.2021.757003] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2021] [Accepted: 10/21/2021] [Indexed: 12/27/2022] Open
Abstract
Background: Neuropsychiatric symptoms (NPS) and cognitive impairments are both common in patients with late-life depression (LLD). However, the relationship between NPS and cognitive functions in LLD patients remains unclear. The current study aims to explore the effects of NPS on cognitive impairments in LLD patients. Methods: Two hundred and sixty-two LLD patients and 141 normal controls (NC) were recruited. Exploratory factor analysis was used to extract factors from the Neuropsychiatric Inventory (NPI). Correlation, mediation, and moderation analyses were used to explore whether NPS exacerbated the cognitive impairments in LLD and whether NPS exhibited different effects on cognitive impairments in acute-state LLD (aLLD) and recovery-state LLD (rLLD). Results: Three main factors were extracted from the NPI, including emotional, behavioral, and psychotic factors. The patients with LLD exhibited worse cognition and higher NPI scores, and the scores of NPI-total and three extracted factors were negatively associated with cognitive scores. The mediation analyses exhibited that NPI-total and behavioral factor scores increase the difference in cognition scores between LLD and NC groups. The mediation analyses exhibited that behavioral factor score played a greater effect on impairing MMSE in the rLLD group than in the aLLD group. Additionally, behavioral factor score was in a trend to be negatively associated with Mini-Mental State Examination (MMSE) score changes at a one-year follow-up (p = 0.051). Conclusions: NPS, especially behavioral symptoms, exacerbate cognitive impairments in LLD and may contribute to residual cognitive impairment in rLLD patients. Early intervention for behavioral symptoms in LLD patients may be beneficial to their long-term clinical prognosis.

Abstract
RATIONALE The serotonergic system has been repeatedly linked to visual attention in general, but the effects of selective serotonin reuptake inhibitor (SSRI) on specific components of visual attention remain unknown. Changes in distinct perceptual and cognitive processes are not readily evident in most attention paradigms. OBJECTIVE In this study, we isolate basic components of visual attention to investigate potential effects of longer-term SSRI administration on non-emotional aspects of visual attention in healthy males. METHODS In a randomized double-blind placebo-controlled design, 32 young healthy males were tested on multiple attentional parameters, before and after a 3-week SSRI intervention with fluoxetine (40 mg daily) or placebo. Data were modeled with a computational theory of visual attention to derive independent estimates of five distinct components of visual attention. RESULTS The SSRI intervention selectively and significantly lowered the threshold for conscious visual perception. Specifically, we demonstrate that this improvement does not stem from a general increase in the speed of visual processing, as previously suggested, but specifically from a change in the perceptual threshold. CONCLUSIONS The study provides a novel description of the attentional dynamics affected by SSRI, while supporting previous findings on attentional effects of SSRI. Furthermore, it accentuates the utility of employing accuracy-based measures of attentional performance when conducting psychopharmacological research.

Abstract
OBJECTIVE Cognitive impairment is common among patients with major depressive disorder (MDD), but its pathological mechanism is complex and not fully understood. Evidence suggests that the kynurenine (KYN) pathway may be implicated in the pathophysiology of depression, but few studies have explored the association between the KYN pathway and cognitive impairment in MDD. Our aim was to examine the relationship between cognitive impairment and KYN pathway metabolites in patients with MDD. METHODS A total of 146 patients with MDD according to DSM-V and 72 healthy controls (HCs) were enrolled, and the severity of depressive symptoms using the 17-item Hamilton Depression Rating Scale (HAMD-17) and cognitive performance including speed of processing, working memory, visual learning and verbal learning were assessed. Blood samples were collected, and serum concentrations of tryptophan (TRP), kynurenine (KYN) and kynurenic acid (KYNA) were measured by liquid chromatography-tandem mass spectrometry. RESULTS In females with MDD, there was a significant negative association between the KYN level and verbal learning (B=-0.039, adjusted p = 0.018), and the KYN/TRP ratio was negatively correlated with speed of processing (B=-470.086, adjusted p = 0.029), verbal learning (B=-544.251, adjusted p = 0.002) and visual learning (B=-513.777, adjusted p = 0.004). Those associations were not present in male individuals with MDD or in HCs, except for a significant negative correlation between the KYNA/KYN ratio and category fluency (B=-0.373, adjusted p = 0.039) in female HCs. CONCLUSION Our results suggest that learning function and speed of processing in female MDD were associated with KYN serum level and the KYN/TRP ratio, potentially implicating the KYN pathway in the pathological mechanism of cognitive function in female MDD.

Abstract
RATIONALE Over-the-counter drugs containing Hypericum perforatum (H. perforatum) have been argued to improve memory and sustained attention. So far, these claims have not been supported in human studies. However, previous studies used rather high dosages, and little is known about the acute effect of small dosages. OBJECTIVE We evaluated whether an acute treatment with Remotiv 500 and Remotiv 250 (500 or 250 mg of H. perforatum quantified to either 1 or 0.5 mg of hypericin) improved memory and sustained attention, as well as mood and state anxiety in healthy adults. METHOD A single dosage, randomized, double-blind, placebo-controlled trial was conducted with 82 student participants (33 women). Each participant received placebo in one session and one of two dosages in the other session. Order of the sessions and dosage conditions were randomized between subjects. Participants completed a battery of tasks assessing short-term memory capacity and sustained attention. RESULTS A significant positive effect of Remotiv 250 on digit span (mean Cohen's d = 0.58; p = .01) was observed. By contrast, Remotiv 500 had a negative effect on digit span (mean d = - 0.48, p = 0.04). A similar effect emerged when factoring across tests of short-term memory. Both dosages improved mood (d = 0.60, p = .03). CONCLUSIONS The results indicate that acute treatment with small (250 mg) dosages of H. perforatum has a positive effect on the capacity of short-term verbal memory, and stress the importance of maintaining small dosages in nootropic applications.

Abstract
BACKGROUND Treatment-resistant depression (TRD) is a serious chronic condition disabling patients functionally and cognitively. Chronic vagus nerve stimulation (VNS) is recognized for the management of TRD, but few studies have examined its long-term effects on cognitive dysfunction in unipolar and bipolar resistant depression. OBJECTIVE The purpose of this study was to assess the course of cognitive functions and clinical symptoms in a cohort of patients treated with VNS for TRD. METHODS In 14 TRD patients with VNS, standardized clinical and neuropsychological measures covering memory, attention/executive functions, and psychomotor speed were analyzed prestimulation and up to 2 years poststimulation. RESULTS Vagus nerve stimulation patients significantly improved on cognitive and clinical measures. Learning and memory improved rapidly after 1 month of stimulation, and other cognitive functions improved gradually over time. Cognitive improvements were sustained up to 2 years of treatment. At 1 month, improvement in Montgomery-Åsberg Depression Rating Scale scores was not correlated with changes in any of the cognitive scores, whereas at 12 months, the change in Montgomery-Åsberg Depression Rating Scale score was significantly correlated with several measures (Stroop interference, verbal fluency, and Rey-Osterrieth Complex Figure delayed recall). CONCLUSIONS In recent years, a growing interest in cognitive dysfunction in depression has emerged. Our results suggest that chronic VNS produces sustained clinical and cognitive improvements in TRD patients, with some mental functions improving as soon as 1 month after the initiation of the VNS therapy. Vagus nerve stimulation seems a very promising adjunctive therapy for TRD patients with cognitive impairment.

Abstract
BACKGROUND This study examined the demographic and rehabilitation service variables affecting employment outcomes of people with affective disorders receiving services from U.S. state-federal vocational rehabilitation (VR) agencies. METHODS An ex post facto design, using data mining as a statistical analysis strategy, was used to analyze the Rehabilitation Services Administration Case Service Report (RSA-911) for the fiscal year 2011. The sample included 44,960 customers with affective disorders who were closed either as successfully employed (Status 26) or not employed (Status 28) by their VR agency. The dependent variable is employment outcome. The predictor variables include a set of personal characteristic variables and rehabilitation service variables. RESULTS The chi-squared automatic interaction detector (CHAID) data mining analysis results indicated that job placement services, on-the-job supports, and job search assistance services were significant predictors of successful employment outcomes for individuals with affective disorders. LIMITATIONS The study used data from the RSA-911 database. Causality cannot be inferred due to the use of archival data. CONCLUSIONS Employment should be viewed as a viable treatment outcome for individuals with affective disorders. Rehabilitation professionals should advocate for their clients to receive VR services, including job placement services, on-the-job supports, and job search assistance services in order to maximize their employment and mental health outcomes.

Abstract
Many patients with chronic psychotic disorders including schizophrenia (SZ) maintain meaningful levels of plasticity (i.e., capacity for change) within neurocognition-relevant brain mechanisms, as evidenced by gains in neurocognition and function after interventions such as targeted cognitive training. However, like many clinical features of these disorders, therapeutic responses in SZ are heterogeneous, and prospectively identifying treatment-sensitive individuals and individualized treatment modalities remains an unmet challenge. We propose that available plasticity in neurocognition-relevant brain mechanisms in individual SZ patients can be detected by gains in laboratory measures of early auditory information processing (EAIP) and auditory learning after a single challenge-dose of a pharmacologic agent; here, we present supportive data for this strategy with the non-competitive NMDA antagonist, memantine, and the psychostimulant, amphetamine. We describe a novel therapeutic model where this "challenge dose" strategy is used to prospectively identify a sensitive cohort of patients, and in these patients, a therapeutic response is elicited by pairing drug-enhanced EAIP and auditory learning with auditory-based targeted cognitive training.

Abstract
Prefrontal cortical executive functions comprise a number of cognitive capabilities necessary for goal directed behavior and adaptation to a changing environment. Executive dysfunction that leads to maladaptive behavior and is a symptom of psychiatric pathology can be instigated or exacerbated by stress. In this review we survey research addressing the impact of stress on executive function, with specific focus on working memory, attention, response inhibition, and cognitive flexibility. We then consider the neurochemical pathways underlying these cognitive capabilities and, where known, how stress alters them. Finally, we review work exploring potential pharmacological and non-pharmacological approaches that can ameliorate deficits in executive function. Both preclinical and clinical literature indicates that chronic stress negatively affects executive function. Although some of the circuitry and neurochemical processes underlying executive function have been characterized, a great deal is still unknown regarding how stress affects these processes. Additional work focusing on this question is needed in order to make progress on developing interventions that ameliorate executive dysfunction.

Abstract
OBJECTIVE Major depressive disorder (MDD) is common and associated with impaired functioning after traumatic brain injury (TBI). Few placebo-controlled antidepressant trials exist in this population. We evaluated the efficacy and tolerability of sertraline for MDD within 1 year of sustaining a TBI. SETTING Level I trauma center. PARTICIPANTS Adults with MDD within 1 year of hospitalization for complicated mild to severe TBI. DESIGN Randomized, double-blind, placebo-controlled trial. MAIN MEASURES Twelve-week treatment response on the 17-item Hamilton Depression Rating Scale. We also assessed symptom improvement and remission. RESULTS We randomized 62 participants: 32% sustained a severe TBI, 68% had significant anxiety, 63% had a history of prior MDD, and 69% had a history of alcohol or drug dependence. Depression significantly improved from baseline to 12 weeks in both treatment groups (P < .001). There were no significant differences between the sertraline and placebo groups over 12 weeks on depression severity, response, or remission. The sertraline group had significant improvement on speed of information processing compared with the placebo group (P < .006). CONCLUSION Sertraline monotherapy was not superior to placebo for MDD in people with post-acute complicated mild to severe TBI. Research is needed on the effectiveness of interventions that also address the significant psychosocial needs of this population.

Abstract
Little is known about age-related cognitive differences in autism spectrum disorder (ASD). However, given the overlap in cognitive impairments in ASD to those seen in typical aging, it is possible that adults with ASD will face even greater cognitive difficulties as they age. The current study used a cross-sectional design to examine age-related cognitive differences in adults with ASD and age and IQ-matched adults with typical development (age range 30-67 years). Results indicated that both age and diagnosis were related to poorer cognitive performance. However, adults with ASD exhibited pronounced age effects on measures related to executive functioning compared to adults with typical development, suggesting that aging in ASD may disproportionately affect specific cognitive processes.

Abstract
Major Depressive Disorders (MDD) patients may exhibit cognitive deficits and it is currently unclear to which degree treatment with antidepressants may affect cognitive function. Preclinical and clinical observations showed that vortioxetine (VORT, an antidepressant with multimodal activity), presents beneficial effects on aspects of cognitive function. In addition, VORT treatment increases adult hippocampal neurogenesis (AHN) in rodents, a candidate mechanism for antidepressant activity. Pattern separation (PS) is the ability to discriminate between two similar contexts/events generating two distinct and non-overlapping representations. Impaired PS may lead to overgeneralization and anxiety disorders. If PS impairments were described in depressed patients, the consequences of antidepressant treatment on context discrimination (CD) are still in its infancy. We hypothesized that VORT-increased AHN may improve CD. Thus, in an attempt to elucidate the molecular mechanism underpinning VORT treatment effects on CD, a rodent model of PS, the role of AHN and stress-induced c-Fos activation was evaluated in the adult mouse hippocampus. Chronic treatment with VORT (1.8 g/kg of food weight; corresponding to a daily dose of 10 mg/kg, 3 weeks) improved CD in mice. Interestingly, chronic treatment with VORT reversed ablation of AHN-induced delay in CD and freezing behavior. VORT treatment decreased stress-induced c-Fos activation in the dorsal but not ventral dentate gyrus. VORT treatment did not affect c-Fos activity in the hippocampus of mice with ablated neurogenesis. This study highlights a role of VORT in CD, which may be independent from AHN and hippocampal c-Fos activation. Further studies elucidating the mechanisms underlying VORT’s effects in CD could contribute to future strategies for alleviating the disease burden for individuals suffering from depression and/or anxiety disorders.

Abstract
BACKGROUND Alcohol is a well-known risk factor in unintentional drownings. Whereas psychotropic drugs, like alcohol, may cause psychomotor impairment and affect cognition, no detailed studies have focused on their association with drowning. Finland provides extensive post-mortem toxicological data for studies on drowning because of its high medico-legal autopsy rates. METHODS Drowning cases, 2000 through 2009, for which post-mortem toxicological analysis was performed, came from the database of the Toxicological Laboratory, Department of Forensic Medicine, University of Helsinki, using the ICD-10 nature-of-injury code T75.1. The data were narrowed to unintentional drowning, using the ICD-10 external-injury codes V90, V92, and W65-74. Each drowning case had its blood alcohol concentration (BAC) and concentrations of other drugs recorded. Evaluation of the contribution of psychotropic drugs to drowning was based on their blood concentration by means of a 6-grade scale. RESULTS Among victims ≥15 years old, unintentional drownings numbered 1697, of which, 303 (17.9%) were boating-related and 1394 (82.1%) non-boating-related. Among these, 65.0% of boating-related and 61.8% of non-boating-related victims were alcohol-positive (=BAC ≥ 50 mg/dL). The male-to-female ratio in alcohol-positive drownings was 7.3. At least one psychotropic drug appeared in 453 (26.7%) drowning cases, with some victims' bodies showing up to 7 different drugs. Overall 70 different psychotropic drugs were detectable, with 134 (7.9%) cases both alcohol-negative and psychotropic-drug-positive, of these, 59 (3.5%) were graded 4 to 6, indicating a possible to very probable contribution to drowning. Our findings suggest that psychotropic drugs may play a significant role in drowning, in up to 14.5% of cases, independently or in association with alcohol. CONCLUSIONS Psychotropic drugs alone or in association with alcohol may be an overlooked risk factor in drowning, due to their effects on psychomotor function and cognition. Future studies should also address other mechanisms-for instance drug-induced long-QT syndrome-by which drugs may contribute to drowning.

Abstract
Individuals with an autism spectrum disorder (ASD) are thought to encounter planning difficulties, but experimental research regarding the mastery of planning in ASD is inconsistent. By means of a meta-analysis of 50 planning studies with a combined sample size of 1755 individuals with and 1642 without ASD, we aim to determine whether planning difficulties do exist and which factors contribute to this. Planning problems were evident in individuals with ASD (Hedges'g = 0.52), even when taking publication bias into account (Hedges'g = 0.37). Neither age, nor task-type, nor IQ reduced the observed heterogeneity, suggesting that these were not crucial moderators within the current meta-analysis. However, while we showed that ASD individuals encounter planning difficulties, the bias towards publishing positive findings restricts strong conclusions regarding the role of potential moderators.

Abstract
Neuropsychological research on adults with ADHD showed deficits in various aspects of attention. However, the majority of studies failed to explore the change of performance over time, so-called time-on-task effects. As a consequence, little is known about sustained attention performance of adults with ADHD. The aim of the present study was therefore to test the hypothesis of sustained attention deficits of adults with ADHD. Twenty-nine adults with ADHD and 30 healthy individuals were assessed on four 20-min tests of sustained attention, measuring alertness, selective attention, divided attention and flexibility. The deterioration of performance over time (time-on-task effects) was compared between patients with ADHD and healthy individuals to conclude on sustained attention performance. Compared to healthy individuals, patients with ADHD showed significant deficits of medium size in selective attention and divided attention. Furthermore, medium sustained attention deficits was observed in measures of alertness, selective attention and divided attention. This study supports the notion of sustained attention deficits of adults with ADHD.

Abstract
OBJECTIVES Baseline and post-concussion neurocognitive testing is useful in managing concussed athletes. Attention deficit hyperactivity disorder (ADHD) and stimulant medications are recognized as potential modifiers of performance on neurocognitive testing by the Concussion in Sport Group. Our goal was to assess whether individuals with ADHD perform differently on post-concussion testing and if this difference is related to the use of stimulants. METHODS Retrospective case-control study in which 4373 athletes underwent baseline and post-concussion testing using the ImPACT battery. 277 athletes self-reported a history of ADHD, of which, 206 reported no stimulant treatment and 69 reported stimulant treatment. Each group was matched with participants reporting no history of ADHD or stimulant use on several biopsychosocial characteristics. Non-parametric tests were used to assess ImPACT composite score differences between groups. RESULTS Participants with ADHD had worse verbal memory, visual memory, visual motor speed, and reaction time scores than matched controls at baseline and post-concussion, all with p ≤ .001 and |r|≥ 0.100. Athletes without stimulant treatment had lower verbal memory, visual memory, visual motor speed, and reaction time scores than controls at baseline (p ≤ 0.01, |r|≥ 0.100 [except verbal memory, r = -0.088]) and post-concussion (p = 0.000, |r|> 0.100). Athletes with stimulant treatment had lower verbal memory (Baseline: p = 0.047, r = -0.108; Post-concussion: p = 0.023, r = -0.124) and visual memory scores (Baseline: p = 0.013, r = -0.134; Post-concussion: p = 0.003, r = -0.162) but equivalent visual motor speed and reaction time scores versus controls at baseline and post-concussion. CONCLUSIONS ADHD-specific baseline and post-concussion neuropsychological profiles, as well as stimulant medication status, may need to be considered when interpreting ImPACT test results. Further investigation into the effects of ADHD and stimulant use on recovery from sport-related concussion (SRC) is warranted.

Abstract
Impaired cognitive function is increasingly recognized in COPD. Yet, the prevalence of cognitive impairment in specific cognitive domains in COPD has been poorly studied. The aim of this cross-sectional observational study was to compare the prevalence of domain-specific cognitive impairment between patients with COPD and non-COPD controls. A neuropsychological assessment was administered in 90 stable COPD patients and 90 non-COPD controls with comparable smoking status, age, and level of education. Six core tests from the Maastricht Aging Study were used to assess general cognitive impairment. By using Z-scores, compound scores were constructed for the following domains: psychomotor speed, planning, working memory, verbal memory, and cognitive flexibility. General cognitive impairment and domain-specific cognitive impairment were compared between COPD patients and controls after correction for comorbidities using multivariate linear and logistic regression models. General cognitive impairment was found in 56.7% of patients with COPD and in 13.3% of controls. Deficits in the following domains were more often present in patients with COPD after correction for comorbidities: psychomotor speed (17.8% vs 3.3%; P<0.001), planning (17.8% vs 1.1%; P<0.001), and cognitive flexibility (43.3% vs 12.2%; P<0.001). General cognitive impairment and impairments in the domains psychomotor speed, planning, and cognitive flexibility affect the COPD patients more than their matched controls.

Abstract
BACKGROUND Patients with heart failure (HF) have high rates of cognitive impairment and depressive symptoms. Depressive symptoms have been associated with greater cognitive impairments in HF; however, it is not known whether particular clusters of depressive symptoms are more detrimental to cognition than others. OBJECTIVE The aim of this study was to identify whether somatic and/or nonsomatic depressive symptom clusters were associated with cognitive function in persons with HF. METHODS Participants were 326 HF patients (40.5% women, 26.7% non-white race-ethnicity, aged 68.6 ± 9.7 years). Depressive symptoms were measured using a depression questionnaire commonly used in medical populations: the Patient Health Questionnaire-9. Somatic and nonsomatic subscale scores were created using previous factor analytic results. A neuropsychological battery tested attention, executive function, and memory. Composites were created using averages of age-adjusted scaled scores. Regressions adjusting for demographic and clinical factors were conducted. RESULTS Regressions revealed that Patient Health Questionnaire-9 total was associated with attention (β = -.14, P = .008) and executive function (β = -.17, P = .001). When analyzed separately, the nonsomatic subscale, but not the somatic symptoms subscale (P values ≥ .092), was associated with attention scores (β = -.15, P = .004) and memory (β = -.11, P = .044). Both nonsomatic (β = -.18, P < .001) and somatic (β = -.11, P = .048) symptoms were related to executive function. When included together, only the nonsomatic symptom cluster was associated with attention (β = -.15, P = .020) and executive function (β = -.19, P = .003). CONCLUSIONS Greater overall depressive symptom severity was associated with poorer performance on multiple cognitive domains, an effect driven primarily by the nonsomatic symptoms of depression. CLINICAL IMPLICATIONS These findings suggest that screening explicitly for nonsomatic depressive symptoms may be warranted and that the mechanisms underlying the depression-cognitive function relationship in HF are not solely related to sleep or appetite disturbance. Thus, interventions that target patients' somatic symptoms only (eg, poor appetite or fatigue) may not yield maximum cognitive benefit compared with a comprehensive treatment that targets depressed mood, anhedonia, and other nonsomatic symptoms.

Abstract
OBJECTIVE Hoarding disorder (HD) is an often incapacitating psychiatric illness associated with a wide range of neurocognitive abnormalities. Some prior neuropsychological studies have found executive dysfunction in HD, but no clear pattern has emerged. One potential reason for discrepant results in previous studies might be the inclusion of patients on psychotropic and other medications that can affect neurocognitive performance. Therefore, we examined neurocognitive functioning in medication-free HD patients. We also added a novel investigation of implicit learning, which has been found to be abnormal in obsessive-compulsive disorder (OCD) and related disorders. METHOD Twenty-six participants meeting the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5; American Psychiatric Association, 2013) diagnostic criteria for HD and 23 normal controls were administered a battery of neuropsychological tests and symptom rating scales. All participants were free of psychotropic medications for at least 6 weeks prior to the study. RESULTS HD participants showed no significant differences from normal controls on measures of verbal memory, attention, or executive functioning, including response inhibition, planning, organization, and decision making. However, HD participants demonstrated a trend toward less implicit learning and greater use of explicit learning strategies during perceptual categorization compared to normal controls. HD participants who used an implicit strategy performed significantly worse than controls who used an implicit strategy. Hoarding symptom severity was not associated with neurocognitive performance. CONCLUSIONS HD patients may have a tendency to use explicit rather than implicit learning strategies for perceptual categorization but perform as well as normal controls on many other neurocognitive measures. Future studies should assess unmedicated participants and examine test strategies, not just outcomes.

Abstract
Agomelatine is a potent agonist at melatonergic 1 and 2 (MT1 and MT2) receptors and an antagonist at serotonin-2C (5HT-2C) receptors. It was suggested that psychotropic effects of agomelatine is associated with its melatonergic and serotonergic effects. In this study, we aimed to evaluate the effects of agomelatine alone or in combination with ritanserin (5HT-2A/2C antagonist) on memory and learning. Male Balb-C mice (25–30 g) were used, and all drugs and saline were administrated by intraperitoneal (i.p.) route 30 min prior to evaluating retention time. Whilst agomelatine was administered at the doses of 1, 10 and 30 mg/kg, ritanserin was administered at the doses of 0.1, 1 and 10 mg/kg. To evaluate memory function, passive avoidance test was used. On the first day, acquisition time and on the second day (after 24h), retention time of mice were recorded. To evaluate the synergistic activity, only the least doses of agomelatine and ritanserine were used, that is, 1 and 0.1 mg/kg, respectively. Scopolamine (1 mg/kg) was used as a reference drug, so it was combined with drug groups. Our results show that 5HT-2A/2C receptor antagonist ritanserin (1 and 4 mg/kg, i.p.) and agomelatine (10 and 30 mg/kg, i.p.) improve memory deficit induced by scopolamine, whilst a synergistic interaction is observed between ritanserin and agomelatine (0.1 mg/kg and 1 mg/kg, i.p., respectively) when they were administered at their ineffective doses. According to our findings, we concluded that agomelatine improves memory deficit and thus improves the effect of agomelatine arises from its 5HT-2C receptor antagonist activity.

Abstract
OBJECTIVES Baseline and post-concussive neurocognitive testing is useful in managing concussed athletes. The Concussion in Sport Group has postulated that the use of psychotropic medications is a modifying factor in the management of sport-related concussion. About 7% of US adolescents are prescribed psychotropics in a given year. Our aim was to investigate whether psychotropic medication use or psychiatric illness is associated with differences in baseline neurocognitive test scores. METHODS From 2007 to 2012, over 7000 athletes underwent pre-participation baseline neurocognitive testing using the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) battery. Following application of inclusion and exclusion criteria, athletes' self-reported medication lists were reviewed and: 1) classified as psychotropic or not and 2) subclassified. Group subclassification yielded: 1) use of any psychotropic medication, 2) psychostimulant use, 3) antidepressant use and 4) self-reported history of depression and/or anxiety without psychotropic use. Each group was matched, by sex, age, body mass index, education level and concussion history with athletes who were not reportedly prescribed psychotropic medications or did not report a depression/anxiety history, respectively. Each group's baseline ImPACT scores were compared to matched controls. RESULTS The use of prescribed psychotropic medications without regard to subclass had no effect on baseline ImPACT composite scores among athletes ages 13-25. However, athletes reportedly prescribed psychostimulants displayed significantly lower visual motor speed scores (32.8 vs 37.1, p = 0.030) and slower reaction times (0.65 vs 0.60, p = 0.044) than non-users. In contrast, antidepressant users displayed significantly faster reaction times (0.58 vs 0.61, p = 0.029). Those reporting a history of depression/anxiety, not treated with psychotropics, displayed significantly lower visual memory (70.4 vs 75.2, p = 0.010) and higher symptom scores (8.83 vs 4.72, p = 0.005). CONCLUSIONS This pilot study suggests that self-reported psychotropic medications are associated with differences in baseline ImPACT test scores, which appear dependent on medication subclass. Our preliminary results support the inclusion of psychotropic medications, specifically psychostimulants and antidepressants, as well as history of depression/anxiety as potential concussion modifiers.

Abstract
Recent research in bipolar disorder (BD) points to the relevance and persistence of cognitive deficits even in euthymia. Up to now, the mechanisms behind why some bipolar patients (BP) do not reach their former level of cognitive performance and psychosocial functioning while others remit completely, are not understood. In this study we aimed to identify a "cognitive deficit" vs. "non-deficit" subgroup within BD by using an extensive neuropsychological test battery. The test performance of 70 euthymic outpatients (BD-I and II, recruited as a sample of convenience from our bipolar disorder programme) was compared to 70 matched, healthy controls (HC). Furthermore, we investigated the association between demographic/clinical variables and the cognitive performance of BP. As expected, our sample of euthymic BP performed significantly worse than HC in psychomotor speed, divided attention, working memory, verbal memory, word fluency and problem solving. However, 41.4% of the patients did not have any neurocognitive deficits at all, and whether or not a patient belonged to the non-deficit group was not influenced by disease severity. Instead, our results demonstrate that patients suffering from persistent sleep disturbances and sub-threshold depressive symptomatology show more severe cognitive dysfunctions. In addition, antipsychotic treatment and comorbid anxiety disorder were associated with cognitive deficits. In sum, these results suggest that a major part of cognitive impairment is due to current symptomatology, especially sleep disorder and sub-syndromal depression. Rigorous treatment of these symptoms thus might well improve cognitive deficits and, as a consequence, overall functioning in BD.

Abstract
Background. Psychiatric consultation is necessary for all patients with intentional poisoning and its reliability depends on the proper function of patients' memory performance. This study aimed to determine the possible memory impairment following acute TCAs' poisoning. Materials and Methods. In this cross-sectional study, patients with acute TCAs poisoning were allocated to two groups of severe poisoning (with coma, seizures, cardiac arrhythmias, hypotension, and a wide QRS complex) and mild-to-moderate poisoning according to their clinical presentation at the time of hospital admission. All patients underwent memory performance test both immediately and 24 hours after their initial consciousness after admission, using Wechsler Memory Scale (WMS-IV). Results. During the study period, 67 TCA-poisoned patients (aged, 20-64 years) were evaluated, of which 67.2% were female. The mean memory scores of patients immediately and 24 hours after the initial consciousness were 31.43 ± 9.02 and 50.62 ± 9.12, respectively (P < 0.001). Twenty-four hours after the initial consciousness, memory score was statistically correlated with the amount of ingested drug and the intoxication severity. Conclusion. Following the recovery from somatic symptoms of acute TCA poisoning, patients may still suffer from memory impairment and it seems that this time is not suitable for performing a reliable psychiatric consultation.

Abstract
OBJECTIVE Bariatric surgery is associated with improved cognitive function, although the mechanisms are unclear. Elevated inflammation is common in obesity and associated with impaired cognition. Inflammation decreases after bariatric surgery, implicating it as a possible mechanism for cognitive improvement. The objective of this study was to examine whether reduced inflammation is a possible mechanism for postoperative cognitive improvement in bariatric surgery patients. METHODS Participants were 77 bariatric surgery patients who completed cognitive testing before surgery and 1 year postsurgery. Cognitive domains assessed were attention/executive function, language, and memory. High-sensitivity C-reactive protein (CRP) was assessed at both time points. RESULTS Patients exhibited preoperative cognitive impairment, although improvements 1 year postsurgery were seen in both attention/executive function (mean [M; standard deviation {SD}]baseline = 53.57 [8.68] versus M (SD)follow-up= 60.32 [8.19]) and memory (M [SD]baseline= 44.96 [7.98] versus M [SD]follow-up= 51.55 [8.25]). CRP was elevated at baseline and fell into the normative range postsurgery (M [SD]baseline= 0.9 [0.7] versus M [SD]follow-up= 0.2 [0.3] mg/dl). Preoperative CRP was not associated with baseline cognitive function (β values = -0.10 to 0.02) and changes in CRP also did not correspond to changes in cognition postsurgery (β values = 0.02-0.11; p values > .05 for all domains). A trend was detected for smaller improvements in memory among participants with elevated baseline CRP (>0.30 mg/dl) versus those with normal levels (group × time: p = .083). CONCLUSIONS Improvements in high-sensitivity CRP were not associated with postoperative cognitive benefits. Future studies are needed to explore other inflammatory markers and potential mechanisms of cognitive improvement after bariatric surgery, including improved glycemic control and neurohormone changes.

Abstract
Patients with major depressive disorder (MDD) are known to present with cognitive deficits; however, the presence of these deficits in the remitted state have been inconsistent. One of the most important factors potentially contributing to inconsistencies between studies may be the influence of medications. To explore the influence of antidepressants on cognitive performance in remitted MDD, we evaluated memory and executive functions using Wechsler Memory Scale-Revised and Stroop Color and Word Test, and compared performance among 50 medicated (29 treated with tricyclic antidepressants [TCA], 21 treated with selective serotonin reuptake inhibitors or serotonin noradrenalin reuptake inhibitors) and 19 medication-free MDD patients and 31 controls. The results showed that all 3 MDD groups had significantly lower performance for verbal memory compared with controls. Both medicated groups showed significantly lower performance for visual memory compared with controls; however, the medication-free group did not differ from controls. For the executive function, only the TCA group showed a significantly lower performance compared with controls. These results suggest that cognitive impairment remained even in remitted patients with MDD, however, part of this impairment may be influenced by class-specific antidepressant side effects.

Abstract
Mutations in the structural protein dystrophin underlie muscular dystrophies characterized by progressive deterioration of muscle function. Dystrophin-deficient mdx mice are considered a model for Duchenne muscular dystrophy (DMD). Individuals with DMD are also susceptible to mood disorders, such as depression and anxiety. Therefore, the study objectives were to investigate the effects of the tricyclic antidepressant amitriptyline on mood, learning, central cytokine expression and skeletal muscle inflammation in mdx mice. Amitriptyline-induced effects (10 mg kg(-1) daily s.c. injections, 25 days) on the behaviour of mdx mice were investigated using the open field arena and tail suspension tests. The effects of chronic amitriptyline treatment on inflammatory markers were studied in the muscle and plasma of mdx mice, and mood-associated monoamine and cytokine concentrations were measured in the amygdala, hippocampus, prefrontal cortex, striatum, hypothalamus and midbrain. The mdx mice exhibited increased levels of anxiety and depressive-like behaviour compared with wild-type mice. Amitriptyline treatment had anxiolytic and antidepressant effects in mdx mice associated with elevations in serotonin levels in the amygdala and hippocampus. Inflammation in mdx skeletal muscle tissue was also reduced following amitriptyline treatment as indicated by decreased immune cell infiltration of muscle and lower levels of the pro-inflammatory cytokines tumour necrosis factor-α and interleukin-6 in the forelimb flexors. Interleukin-6 mRNA expression was remarkably reduced in the amygdala of mdx mice by chronic amitriptyline treatment. Positive effects of amitriptyline on mood, in addition to its anti-inflammatory effects in skeletal muscle, may make it an attractive therapeutic option for individuals with DMD.

Abstract
Neither pain, nor depression exist as independent phenomena per se, they are highly subjective inner states, formed by our brain and built on the bases of our experiences, cognition and emotions. Chronic pain is associated with changes in brain physiology and anatomy. It has been suggested that the neuronal activity underlying subjective perception of chronic pain may be divergent from the activity associated with acute pain. We will discuss the possible common pathophysiological mechanism of chronic pain and depression with respect to the default mode network of the brain, neuroplasticity and the effect of antidepressants on these two pathological conditions. The default mode network of the brain has an important role in the representation of introspective mental activities and therefore can be considered as a nodal point, common for both chronic pain and depression. Neuroplasticity which involves molecular, cellular and synaptic processes modifying connectivity between neurons and neuronal circuits can also be affected by pathological states such as chronic pain or depression. We suppose that pathogenesis of depression and chronic pain shares common negative neuroplastic changes in the central nervous system (CNS). The positive impact of antidepressants would result in a reduction of these pathological cellular/molecular processes and in the amelioration of symptoms, but it may also increase survival times and quality of life of patients with chronic cancer pain.

Abstract
Over more than a century of research has established the fact that sleep benefits the retention of memory. In this review we aim to comprehensively cover the field of "sleep and memory" research by providing a historical perspective on concepts and a discussion of more recent key findings. Whereas initial theories posed a passive role for sleep enhancing memories by protecting them from interfering stimuli, current theories highlight an active role for sleep in which memories undergo a process of system consolidation during sleep. Whereas older research concentrated on the role of rapid-eye-movement (REM) sleep, recent work has revealed the importance of slow-wave sleep (SWS) for memory consolidation and also enlightened some of the underlying electrophysiological, neurochemical, and genetic mechanisms, as well as developmental aspects in these processes. Specifically, newer findings characterize sleep as a brain state optimizing memory consolidation, in opposition to the waking brain being optimized for encoding of memories. Consolidation originates from reactivation of recently encoded neuronal memory representations, which occur during SWS and transform respective representations for integration into long-term memory. Ensuing REM sleep may stabilize transformed memories. While elaborated with respect to hippocampus-dependent memories, the concept of an active redistribution of memory representations from networks serving as temporary store into long-term stores might hold also for non-hippocampus-dependent memory, and even for nonneuronal, i.e., immunological memories, giving rise to the idea that the offline consolidation of memory during sleep represents a principle of long-term memory formation established in quite different physiological systems.

Abstract
BACKGROUND Adult survivors of childhood cancer are at risk for long-term morbidities, which may be managed pharmacologically. Psychoactive medication treatment has been associated with adverse effects on specific neurocognitive processes in non-cancer populations, yet these associations have not been examined in adult survivors of childhood cancer. PROCEDURE Outcomes were evaluated in 7,080 adult survivors from the Childhood Cancer Survivor Study (CCSS) using a validated self-report Neurocognitive Questionnaire. Multivariable logistic regression models were used to calculate odds ratios (OR) and 95% confidence intervals (CI) for neurocognitive impairment using demographic and treatment factors and survivors' report of prescription medication use. RESULTS Controlling for cranial radiation, pain, psychological distress, and stroke/seizure, use of antidepressant medications was associated with impaired task efficiency (OR = 1.80, 95% CI = 1.47-2.21), organization (OR = 1.83, 95% CI = 1.48-2.25), memory (OR = 1.53, 95% CI = 1.27-1.84), and emotional regulation (OR = 2.06, 95% CI = 1.70-2.51). Neuroleptics and stimulants were associated with impaired task efficiency (OR = 2.46, 95% CI = 1.29-4.69; OR = 2.82, 95% CI = 1.61-4.93, respectively) and memory (OR = 2.08, 95% CI = 1.13-3.82; OR = 2.69, 95% CI = 1.59-4.54, respectively). Anticonvulsants were associated with impaired task efficiency, memory, and emotional regulation, although survivors who use these medications may be at risk for neurocognitive impairment on the basis of seizure disorder and/or underlying tumor location (CNS). CONCLUSIONS These findings suggest that specific psychoactive medications and/or mental health conditions may be associated with neurocognitive function in adult survivors of childhood cancer. The extent to which these associations are causal or indicative of underlying neurological impairment for which the medications are prescribed remains to be ascertained.

Abstract
Prior research has suggested that depression is characterized by impaired cognitive control. The present study sought to investigate internal cognitive control impairments related to emotional information and task settings in clinical depression (MDD, major depressive disorder). Internal cognitive control was operationalized as switching between internally held mental representations that required continuous updating in working memory and measured with the Internal Shift Task (IST). The results showed that MDD individuals were characterized by a general switching impairment. This switching impairment was neither influenced by the task-relevance of emotional information, nor influenced by the valence of the faces within the emotion condition. The impairment in cognitive control reflected in general switching impairments was related to rumination, a specific cognitive symptom and important risk factor of depression. The results of this study offer new insights into the relationship between depression and impaired cognitive control with potential clinical implications, informing treatment and prevention programmes.

Abstract
Neuropsychological impairment is prominent in patients with depression, but it is unclear whether deficits persist after clinical response. This study aimed to investigate neuropsychological functions in the course of the illness. Depressive patients were investigated in the acute state and after clinical response using an extensive neuropsychological test battery. After clinical response, there was only a partial improvement in learning and memory and there were no changes regarding working memory, executive functions, and attention. Transient impairments in visual learning and memory suggest a depression-related state effect. The continuing deficits in attention, working memory, and executive function might be considered a trait marker.

Abstract
Sleep related symptoms of depression include sleep fragmentation, early morning awakening, decreased rapid eye movement (REM) sleep latency, increased REM density, and more negative dream content. Most tricyclic antidepressants (ADs) increase total sleep time and decrease wake time after sleep onset, while many selective serotonin reuptake inhibitors (SSRIs) have an opposite effect. However, almost all ADs prolong REM sleep latency and reduce the amount of REM sleep. Case reports and research data indicate a strong effect of ADs on dream recall and dream content. We performed a systematic review (1950 to August 2010) about ADs impact on dreaming in depressive patients and healthy volunteers. Twenty-one clinical studies and 25 case reports were eligible for review and document a clear AD effect on dreaming. The major finding, both in depressed patients and in healthy volunteers, is a decrease of dream recall frequency (DRF) under ADs. This is a rather consistent effect in tricyclic ADs and phenelzine, less consistently documented also for SSRIs/serotonin norepinephrine reuptake inhibitors (SNRIs). Tricyclic ADs induce more positive dream emotions. Withdrawal from tricyclic ADs and from the monoamine oxidase inhibitors phenelzine and tranylcypromine may cause nightmares. Intake and even more withdrawal of SSRIs/SNRIs seem to intensify dreaming, which may be experienced in different ways; a potential to cause nightmares has to be taken into account. Though there are clear-cut pharmacological effects of ADs on DRF and dream content, publications have been surprisingly scarce during the past 60 years. There is evidence of a gap in neuropsychopharmacological research. AD effects on dreams should be recognized and may be used in treatment.

Abstract
Driving a car is vital for the functional autonomy of patients to take part in activities of daily living. Both psychopathologic symptoms and psychopharmacologic treatment may impair driving ability. This article provides a systematic review of published studies (1980-2011) on commonly prescribed newer antidepressants and driving performance. A total of 21 studies could be included in the review, indicating that there is a lack of controlled patient studies. Investigations on newer antidepressants were frequently undertaken in healthy subjects focusing on acute or subchronic effects of application, predominately in young male participants, with dosages usually given in an ambulatory setting. No data, according to selection criteria, were found with respect to agomelatine, duloxetine, bupropion and viloxazine. There is evidence that the SSRIs (citalopram, escitalopram, fluoxetine, fluvoxamine, sertraline, paroxetine) and the SNRI venlafaxine have no deleterious effects on driving ability. Acute use of mirtazapine does produce impairments that diminish to some degree when given as a nocturnal dose and cannot be seen after repeated dosing in healthy controls. Patients obviously benefit from treatment with newer antidepressants; however, at least a subgroup does not reach performance level of healthy subjects. More patient studies are needed that elaborate specific relationships between clinical subtypes of the illness and response to different antidepressants, considering course and duration of illness, co-morbidities and not least neuropsychological and neurobiological characteristics.

Correlations between Stroop task performance and white matter lesion measures in late-onset major depression. Psychiatry Res 2012; 202:142-9. [PMID: 22703621 DOI: 10.1016/j.pscychresns.2011.12.009] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2011] [Revised: 10/18/2011] [Accepted: 12/18/2011] [Indexed: 10/28/2022]
Abstract
Cerebral white matter lesions (WMLs) are believed to play an important role in a subset of patients with late-onset depression by affecting the white matter connectivity in circuitries essential for mood and cognition. In this study we used diffusion tensor imaging-based (DTI-based) tractography to assess white matter fiber tracts affected by deep WMLs (DWMLs) in patients with late-onset major depression and age- and gender-matched controls. Tractography outcome, illustrated as pathways affected by DWMLs, was analyzed for associations with cognitive performance on the Stroop Test (ST). The patients (n=17) performed significantly worse on the ST than the controls (n=22). Poor performance on the ST correlated with higher lesion load. Regression analysis showed a significant correlation between poor performance on the ST and tracts affected by DWMLs in multiple brain areas in the control group, but very sparse correlation in the patient group. Our results suggest that DWMLs play an important role in the cognitive performance of controls,whereas their influence in depressed patients is overruled by additional, state-dependent factors. Future focus on the tract-specific localization of WMLs using DTI tractography may reveal important associations between neuroconnectivity and clinical measures.
