Background: The aim of this study was to characterise long-term neurological and neurocognitive sequelae after tick-borne encephalitis (TBE) in adults. Methods: 98 prospective consecutive TBE patients, classified by disease severity, were included. Immediate outcomes were evaluated with Glasgow Outcome Scale (GOS) and Rankin Scale (RS). After 6 and 18 months, long-term disability was evaluated using Modified Rankin Scale (MRS) and neurocognitive assessment was performed with Matrics Consensus Cognitive Battery (MCCB), measuring processing speed, attention/vigilance, working memory, verbal learning, visual learning, reasoning/problem solving and social cognition. The MCCB results were compared to healthy age, gender and education-matched controls. Results: Mild, moderate, and severe TBE was diagnosed in 53.1%, 38.8%, and 8.2% of cases, respectively. At discharge, 25.5% of the patients had major or moderate impairments (GOS) and various levels of disability in 34.7% (RS). Up to 18 months from the onset of TBE, over 20% remained with slight to moderate disability (MRS). GOS, RS and MRS scores correlated with disease severity. At 6 months after the onset, TBE patients scored significantly lower than controls in processing speed, verbal, and visual learning. Two latter domains were significantly more impaired in patients with mild TBE. Patients aged 18-39 performed significantly worse in attention/vigilance and working memory, whereas aged 60+ in verbal learning. A year later, significant improvement was observed in six of seven cognitive domains. Conclusions: Long-term neurological sequelae persist in a substantial proportion of TBE patients with significant impairment in several cognitive domains, especially in younger patients and even after mild TBE.

- Abstract
Cerebral stroke consequence assessment in patients with residual schizophrenia is a complex clinical scenario questioning both diagnostic and therapeutic strategies. Aim. To assess the structure of neurocognitive dysfunctions in patients with residual schizophrenia with pronounced negative symptoms depending on a history of cerebral stroke. Materials and methods. In the period of 2020-2023, a clinical examination of 47 patients of Zaporizhzhia Regional Clinical Psychiatric Hospital and Veselovsky Psychoneurological Boarding School with a diagnosis of residual schizophrenia (ICD-10: F20.5) was carried out. Study groups were formed: G1 - 9 patients with residual schizophrenia and the history of cerebral stroke; G2 - 36 patients with residual schizophrenia without the history of cerebral stroke. Results. The DSM-5 neurocognitive functioning assessment system was used in the study, based on which a protocol for rapid testing of neurocognitive functions adapted for patients with residual schizophrenia was developed. The group of patients with the history of cerebral stroke has demonstrated lower results in attention allocation (p ≤ 0.05). This group has also shown relatively poor results in planning (p ≤ 0.05), error correction (p ≤ 0.05), inhibition (p ≤ 0.05) and flexibility (p ≤ 0.05). As concerning verbal ability, worse results of expressive speech (p ≤ 0.05), grammar and syntax (p ≤ 0.05) have been revealed in the group of patients with the history of cerebral stroke. In terms of perceptual-motor functions, the gnosis task has been performed worse (p ≤ 0.05) by the group of patients with the history of cerebral stroke. Differences in emotion recognition and theory of mind were insignificant between groups. Conclusions. An original neurocognitive function assessment protocol adapted for the Ukrainian-speaking patient population with residual schizophrenia has been developed. The patient population with residual schizophrenia and the history of cerebral stroke or without it has been examined with the use of the developed protocol for the assessment of neurocognitive functions. According to the obtained results, patients with residual schizophrenia and the history of cerebral stroke have demonstrated worse cognitive performance compared to those without the history of stroke.

Type 1 diabetes mellitus (DM) is a common childhood endocrinopathy that can present with cognitive dysfunction (CD). PubMed, Cochrane Library, eLIBRARY.RU and Medscape databases were searched for Englishand Russian-language articles published from 2010 to 2023 using the following keywords: type 1 diabetes mellitus, children, cognitive dysfunction and diagnosis. Publications on CD in adult patients with type 1 DM were excluded from this review. In children with DM, the aetiology of CD is multifactorial and has the following confirmed risk factors: acute hypoglycaemia, chronic hyperglycaemia, early DM onset and pronounced diabetic ketoacidosis. CD manifests clinically with declined memory, attention, IQ scores, psychomotor reactions and cognitive flexibility. In children with an early disease onset (before the age of 6), CD manifestations are more pronounced. The neuropsychological methods considered part of the gold standard for CD diagnosis in children are: the Stroop Colour and Word Test, Benton Visual Retention Test, Wechsler Intelligence Scale for Children, and Wisconsin Card Sorting Test. The representative instrumental methods include magnetic resonance imaging, electroencephalography, diffusion tensor imaging, etc. They allow us to assess the anatomical and functional changes in the brain of children with type 1 DM. Laboratory-based methods can detect an increase in neurospecific proteins and inflammation markers, which indicates cerebral damage in patients with the disease. Further research is necessary on type 1 DM-associated CD in paediatric practice in order to improve the diagnostic criteria for this complication and its prevention methods.

The Color Trails Test (CTT) is a pencil-and-paper (P&P) neuropsychological test. The CTT is divided into two parts that assess sustained visual attention (Trails A) and divided attention (Trails B). The CTT can also be performed in a virtual reality setting (VR-CTT) introducing a wider spatial range of targets. In cases of multiple assessments, repeating the same CTT configuration can bias the results due to fatigue and learning effects. The aim of this study is to create five different short versions of the VR-CTT. The different forms were created by rotating or flipping the original targets spatial layout on one of the axes and by ending it at ball #13. Healthy young participants (N = 15) performed the shortened VR-CTT forms (in a counterbalanced order), the P&P CTT and the original VR-CTT. We found no difference between the completion times of the five forms (p > 0.2), and a significant difference between Trails A and B across all forms (p < 0.04). Additionally, there was no evidence of a learning effect between trials (p > 0.4). Moreover, the shortened VR-CTT forms showed correlations with the P&P CTT (p < 0.05) and with the original VR-CTT (p < 0.06). These findings suggest that all five forms have an equal level of difficulty and that the different forms managed to mitigate the learning effects reported for repeated testing of the same spatial layout. This opens the possibility of applying the shortened VR-CTT forms for research settings and sets the basis for developing it into a clinical diagnostics tool. [ABSTRACT FROM AUTHOR]

Background: The digit span test (DST) is one of the most widely used neuropsychological tools to measure two neurocognitive functions of working memory and attention. Objectives: This study aimed to collect Iranian normative data on DST and examine the association between three demographic variables and performance in DST. Materials & Methods: As part of the Iranian brain imaging database (IBID) project, the present study was conducted in 2017-2018 on three hundred normal people aged 20 to 70. They were recruited using convenience sampling in Tehran City, Iran. Each decade consisted of 60 participants, and the gender proportion was equal. Five decades of age, gender and education were the independent variables. The dependent variables were DST scores (the longest digit sequence and total digit span). Results: Age and education had a significant negative and positive correlation with both subtests (P=0.01), respectively; however, no significant correlation was observed between gender and DST scores (P>0.05). According to multivariate analysis of variance, the interaction of age, gender and education did not lead to a significant difference in the DST scores (P=0.309). In addition, The Tukey post hoc test showed that participants under 40 had significantly higher DST scores than older participants (P

Normal pressure hydrocephalus can be treated with ventriculoperitoneal shunt (VPS) placement, but no broadly implemented indication for VPS exists. Our protocol consists of physical therapy and occupational therapy practitioners administering validated tests of gait, balance, and cognition before and after lumbar drain placement. Specific tests include: Timed "Up & Go", Tinetti Gait and Balance Assessment, Berg Balance Scale, Mini Mental Status Exam, Trail Making Test Part B, and the Rey Auditory and Visual Learning Test. Minimal clinically important difference values for each test were determined from literature review. A retrospective review of patients treated under this protocol was performed. The primary outcomes were candidacy for VPS based on the protocol and patient-reported symptomatic improvement after VPS placement. A total of 48/75 (64%) patients received VPS. A total of 43/48 (89.6%) of those shunted reported improved symptoms at 6-week follow-up. However, 10/22 (45.5%) reported worsening symptoms at 1-year follow-up. The mean Tinetti score significantly increased after lumbar drain in patients who improved with VPS compared to the no shunt group (4.27 vs. −0.48, P < 0.001). A total of 6/33 (18%) patients with postoperative imaging had a subdural fluid collection identified and 3/49 (6%) had other complications, including 1 seizure, 1 intracerebral hemorrhage, and 1 stroke. Standardized assessment of gait, balance, and cognition before and after temporary cerebrospinal fluid diversion identifies patients with normal pressure hydrocephalus likely to benefit from VPS placement with a low complication rate. One year after VPS, approximately one half of patients had symptoms recurrence. [ABSTRACT FROM AUTHOR]

Background: Expedient diagnosis of incipient dementia is often hindered by time constraints in primary care visits, shortage of dementia specialists, and extended waitlists for comprehensive neuropsychological evaluations. Methods: We developed the Rapid Access Memory Program (RAMP) to improve access of neuropsychological services for older adults presenting to our institutional primary care clinics with concerns of cognitive decline. RAMP provides abbreviated neurocognitive assessment, same-day patient feedback, expedited reporting to referring providers, and is financially self-supported. Here, we describe development of RAMP and clinical outcomes from the first 3 years. Results: Of 160 patients seen, dementia was diagnosed in 30% and Mild Cognitive Impairment in 50%; Alzheimer's disease was the most common suspected etiology. New psychiatric diagnosis was made in about one-third (n = 54). Most frequent recommendations involved medication adjustments (initiating cholinesterase inhibitors, deprescribing anticholinergics), safety (driving, decision-making), and specialist referrals. Additionally, 27 (17%) subsequently enrolled in local research. Conclusions: Results support feasibility and utility of RAMP for connecting older adults in primary care with neuropsychological services. [ABSTRACT FROM AUTHOR]

- Abstract
INTRODUCTION: The contribution of neuropsychological assessments to risk assessment for incident dementia is underappreciated. METHODS: We analyzed neuropsychological testing results in dementia‐free participants in the Atherosclerosis Risk in Communities (ARIC) study. We examined associations of index domain–specific neuropsychological test performance with incident dementia using cumulative incidence curves and Cox proportional hazards models. RESULTS: Among 5296 initially dementia‐free participants (mean [standard deviation] age of 75.8 [5.1] years; 60.1% women, 22.2% Black) over a median follow‐up of 7.9 years, the covariate‐adjusted hazard ratio varied substantially depending on the pattern of domain‐specific performance and age, in an orderly manner from single domain language abnormalities (lowest risk) to single domain executive or memory abnormalities, to multidomain abnormalities including memory (highest risk). DISCUSSION: By identifying normatively defined cognitive abnormalities by domains based on neuropsychological test performance, there is a conceptually orderly and age‐sensitive spectrum of risk for incident dementia that provides valuable information about the likelihood of progression. Highlights: Domain‐specific cognitive profiles carry enhanced prognostic value compared to mild cognitive impairment.Single‐domain non‐amnestic cognitive abnormalities have the most favorable prognosis.Multidomain amnestic abnormalities have the greatest risk for incident dementia.Patterns of domain‐specific risks are similar by sex and race.

Objectives. To study the features of and relationships between neuropsychological and metabolic indicators in patients with cognitive disorders (CD) of the Alzheimer's and vascular types of different severities Materials and methods. A total of 177 patients took part, including 85 with Alzheimer's disease (AD) and 92 with vascular CD (VCD). All patients underwent comprehensive neuropsychological examination; 18F-deoxyglucose positron emission tomography was performed in 17 patients with AD and 15 patients with VCD. Results. The greatest changes in patients with AD were noted in the mnestic domain, indicators being significantly different from those of patients with VCD even at the pre-dementia stage. Neurodynamic and dysregulatory disorders were predominant in patients with VCD. Patients with AD showed symmetrical bilateral decreases in metabolic activity in the parietal and temporal cortex, often in combination with marked hypometabolism in the hippocampal region. Patients with VCD showed areas of decreased metabolism in different locations and of different sizes, mainly in the projection of the basal ganglia and in the prefrontal and parietal areas of the cortex, as well as in the cingulate gyrus, providing indirect confi rmation of the mechanism of uncoupling of subcortical and cortical structures. In patients with AD, impaired metabolic activity in the hippocampal region correlated with impaired temporal and spatial orientation (ϱ = –0.54, p < 0.05) and memory impairment (ϱ = –0.71, p < 0.005). Hypometabolism of the parietal lobe cortex was linked with the total score on the Mini Mental State Examination (ϱ = –0.8, p < 0.001), the 10-word memory test (ϱ = –0.89, p < 0.001 and ϱ = –0.82, p < 0.001), visuospatial impairment (ϱ = –0.64, p < 0.01), and the categorical association test (ϱ = –0.73, p < 0.005). In patients with VCD, dysregulatory disorders correlated with hypometabolism in the thalamus (ϱ = –0.56, p < 0.05), prefrontal cortex (ϱ = –0.64, p < 0.05), and cingulate gyrus (anterior sections) (ϱ = –0.53, p < 0.05). Conclusions. The results obtained here indicate that there are differences in CD and cerebral metabolism between patients with AD and VCD. [ABSTRACT FROM AUTHOR]

BACKGROUND: Functional dyspepsia is a disorder of gut-brain interaction that has the potential to impact aviation performance. Proton pump inhibitors are well-tolerated but are only effective in one half of cases. Second-line treatments, including tricyclic antidepressants, are associated with drowsiness and are not routinely approved for use in aviators. We present a case of a Naval Flight Officer with functional dyspepsia who was successfully treated with amitriptyline and returned to flying status. CASE REPORT: A 23-yr-old male Naval Flight Officer presented with postprandial fullness and epigastric pain. His symptoms were refractory to trials of acid suppression and lifestyle modification. An extensive evaluation by Gastroenterology, including upper endoscopy, did not reveal an organic cause of his symptoms and he was diagnosed with functional dyspepsia. The patient's symptoms resolved with a trial of amitriptyline. Neuropsychological testing demonstrated no medication effect on cognitive performance. A waiver to resume flying duties on amitriptyline was submitted to the Naval Aerospace Medical Institute and was approved. DISCUSSION: We present the second known waiver issued in U.S. Naval aviation history for the use of amitriptyline to treat a gastrointestinal disorder. Amitriptyline is not commonly waived due to the potential for unacceptable cognitive side-effects in the flight environment. However, neuropsychological testing to assess for a possible medication effect on performance can be used to inform an aeromedical disposition and, in this case, allowed for a return to flight status.

Background: Practice effects on cognitive testing in mild cognitive impairment (MCI) and Alzheimer's disease (AD) remain understudied, especially with how they compare to biomarkers of AD. Objective: The current study sought to add to this growing literature. Methods: Cognitively intact older adults (n = 68), those with amnestic MCI (n = 52), and those with mild AD (n = 45) completed a brief battery of cognitive tests at baseline and again after one week, and they also completed a baseline amyloid PET scan, a baseline MRI, and a baseline blood draw to obtain APOE ɛ4 status. Results: The intact participants showed significantly larger baseline cognitive scores and practice effects than the other two groups on overall composite measures. Those with MCI showed significantly larger baseline scores and practice effects than AD participants on the composite. For amyloid deposition, the intact participants had significantly less tracer uptake, whereas MCI and AD participants were comparable. For total hippocampal volumes, all three groups were significantly different in the expected direction (intact > MCI > AD). For APOE ɛ4, the intact had significantly fewer copies of ɛ4 than MCI and AD. The effect sizes of the baseline cognitive scores and practice effects were comparable, and they were significantly larger than effect sizes of biomarkers in 7 of the 9 comparisons. Conclusion: Baseline cognition and short-term practice effects appear to be sensitive markers in late life cognitive disorders, as they separated groups better than commonly-used biomarkers in AD. Further development of baseline cognition and short-term practice effects as tools for clinical diagnosis, prognostic indication, and enrichment of clinical trials seems warranted.

In this fifth decade of the human immunodeficiency virus (HIV) epidemic, central nervous system (CNS) complications including cognitive impairment and mental health remain a burden for people with HIV (PWH) on antiretroviral therapy. Despite the persistence of these complications, which often co-occur, the underlying pathophysiology remains elusive and consequently treatments remain limited. To continue to grow our understanding of the underlying mechanisms of CNS complications among PWH, there is a need to reexamine our current approaches, which are now more than 2 decades old. At the 2021 National Institutes of Health-sponsored meeting on Biotypes of CNS Complications in PWH, the Neurobehavioral Working Group addressed the following: (1) challenges inherent to determining CNS complications; (2) heterogeneity in CNS complications; and (3) problems and solutions for examining integrated biotypes. The review below provides a summary of the main points presented and discussed by the Neurobehavioral Working Group at the meeting.

There is a critical need for accessible neuropsychological testing for basic research and translational studies worldwide. Traditional in-person neuropsychological studies are inherently difficult to conduct because testing requires the recruitment and participation of individuals with neurological conditions. Consequently, studies are often based on small sample sizes, are highly time-consuming, and lack diversity. To address these challenges, in the last decade, the utilization of remote testing platforms has demonstrated promising results regarding the feasibility and efficiency of collecting patient data online. Herein, we tested the validity and generalizability of remote administration of the Montreal Cognitive Assessment (MoCA) test. We administered the MoCA to English and Hebrew speakers from three different populations: Parkinson's disease, Cerebellar Ataxia, and healthy controls via video conferencing. First, we found that the online MoCA scores do not differ from traditional in-person studies, demonstrating convergent validity. Second, the MoCA scores of both our online patient groups were lower than controls, demonstrating construct validity. Third, we did not find differences between the two language versions of the remote MoCA, supporting its generalizability to different languages and the efficiency of collecting binational data (USA and Israel). Given these results, future studies can utilize the remote MoCA, and potentially other remote neuropsychological tests to collect data more efficiently across multiple different patient populations, language versions, and nations.

INTRACRANIAL hypertension , *COGNITIVE processing speed , *COGNITIVE testing , *COGNITION , *COGNITIVE analysis , *BODY mass index - Abstract
Background: Cognitive disturbance is not pathognomonic of idiopathic intracranial hypertension (IIH), and therefore is not routinely assessed unless it presents as a major complaint. Consequently, cognition has been slow to gain substantial traction in IIH-related research, despite its notable impact on a subset of patients. We completed a systematic review of the literature examining the neurocognitive profile of patients with IIH. Methods: A PRISMA compliant literature search was conducted in Ovid Medline, PubMed, PsycInfo, Embase, Web of Science, Cochrane, Cinahl, and Scopus databases. The initial query yielded 1376 unique articles. These articles were narrowed to those including empirical analyses of cognitive assessment in adult patients with IIH. Results: A final cohort of nine articles resulted, comprising the findings from 309 patients with IIH and 153 healthy control subjects. Although there was considerable variability in methodology particularly with respect to cognitive assessment, fairly consistent deficits were observed across studies in the domains of processing speed, working memory, sustained and complex attention, set-shifting, and confrontation naming. Body mass index and body weight were not associated with cognitive performance. Pertinent limitations of the literature were identified, most notably failure to report trial-level cognitive testing data, the need for more comprehensive testing batteries with less reliance on screening tools, and not controlling for variables that may impact cognition. Conclusions: A more complete understanding of the cognitive profile in patients with idiopathic intracranial hypertension could lead to the increased -relevance of cognitive screening in disease management, and therefore more appropriate neuropsychological referral, earlier identification of functional limitations, and targeted neurorehabilitation.

The pathophysiological development of Alzheimer's disease (AD) begins in the brain years before the onset of clinical symptoms. The accumulation of beta‐amyloid (Aβ) is thought to be the first cortical pathology to occur. Carrying one apolipoprotein E (APOE) ε4 allele increases the risk of developing AD at least 2–3 times and is associated with earlier Aβ accumulation. Although it is difficult to identify Aβ‐related cognitive impairment in early AD with standard cognitive tests, more sensitive memory tests may be able to do this. We sought to examine associations between Aβ and performance on three tests within three subdomains of memory, verbal, visual, and associative memory, to elucidate which of these tests were sensitive to Aβ‐related cognitive impairment in at‐risk subjects. 55 APOE ε4 carriers underwent MRI, 11C‐Pittsburgh Compound B (PiB) PET, and cognitive testing. A composite cortical PiB SUVR cut‐off score of 1.5 was used to categorise subjects as either APOE ε4 Aβ+ or APOE ε4 Aβ−. Correlations were carried out using cortical surface analysis. In the whole APOE ε4 group, we found significant correlations between Aβ load and performance on verbal, visual, and associative memory tests in widespread cortical areas, the strongest association being with performance on associative memory tests. In the APOE ε4 Aβ+ group, we found significant correlations between Aβ load and performance of verbal and associative, but not visual, memory in localised cortical areas. Performance on verbal and associative memory tests provides sensitive markers of early Aβ‐related cognitive impairment in at‐risk subjects. [ABSTRACT FROM AUTHOR]

Objective: To replicate a seven-factor model previously reported for the Delis–Kaplan Executive Function System (D-KEFS). Method: This study used the D-KEFS standardization sample including 1,750 non-clinical participants. Several seven-factor models previously reported for the D-KEFS were re-evaluated using confirmatory factor analysis (CFA). Previously published bi-factor models were also tested. These models were compared with a three-factor a priori model based on Cattell–Horn–Carroll (CHC) theory. Measurement invariance was examined across three age cohorts. Results: All previously reported models failed to converge when tested with CFA. None of the bi-factor models converged after large numbers of iterations, suggesting that bi-factor models are ill-suited to represent the D-KEFS scores as reported in the test manual. Although poor fit was initially observed for the three-factor CHC model, inspection of modification indices showed potential for improvement by including method effects via correlated residuals for scores derived from similar tests. The final CHC model showed good to excellent fit and strong metric measurement invariance across the three age cohorts with minor exceptions for a subset of Fluency parameters. Conclusions: CHC theory extends to the D-KEFS, supporting findings from previous studies that executive functions can be integrated into CHC theory. [ABSTRACT FROM AUTHOR]

Vascular cognitive impairment (VCI) encompasses a wide range of conditions, including cognitive impairment associated with stroke or vascular brain injury, mild vascular cognitive impairment, and vascular dementia (VD). Knowledge of language impairment associated with VD is far less extensive than that of Alzheimer's disease. Although not prevalent in VD, impairment in language skills has been reported. A better understanding of the neurolinguistic features associated with the different presentations of VD could facilitate medical diagnosis. In this article, we report data on language impairment in VD, with particular attention to their primary or secondary functional origin. To better appreciate this functional origin, we also outline the main characteristics of impairment in other cognitive functions. Key elements that should be considered in the speech-language assessment of individuals with possible or proven VD are also highlighted. [ABSTRACT FROM AUTHOR]

Cognitive impairment and post-concussive symptoms (PCS) represent hallmark sequelae of pediatric mild traumatic brain injury (pmTBI). Few studies have directly compared cognition as a function of PCS status longitudinally. Cognitive outcomes were therefore compared for asymptomatic pmTBI, symptomatic pmTBI, and healthy controls (HC) during sub-acute (SA; 1–11 days) and early chronic (EC; approximately 4 months) post-injury phases. We predicted worse cognitive performance for both pmTBI groups relative to HC at the SA visit. At the EC visit, we predicted continued impairment from the symptomatic group, but no difference between asymptomatic pmTBI and HCs. A battery of clinical (semi-structured interviews and self-report questionnaires) and neuropsychological measures were administered to 203 pmTBI and 139 HC participants, with greater than 80% retention at the EC visit. A standardized change method classified pmTBI into binary categories of asymptomatic or symptomatic based on PCS scores. Symptomatic pmTBI performed significantly worse than HCs on processing speed, attention, and verbal memory at SA visit, whereas lower performance was only present for verbal memory for asymptomatic pmTBI. Lower performance in verbal memory persisted for both pmTBI groups at the EC visit. Surprisingly, a minority (16%) of pmTBI switched from asymptomatic to symptomatic status at the EC visit. Current findings suggest that PCS and cognition are more closely coupled during the first week of injury but become decoupled several months post-injury. Evidence of lower performance in verbal memory for both asymptomatic and symptomatic pmTBI suggests that cognitive recovery may be a process separate from the resolution of subjective symptomology.

Almost 10 years ago Prichard et al. (2013) published a literature review on consistency of handedness. They described how consistency of handedness, typically measured by the Edinburgh Handedness Inventory (EHI), predicted outcomes in memory and decision-making paradigms better than direction of handedness. In the last 10 years, new research has extended these findings and added new theoretical perspectives. The goal of this short form review is to highlight and summarize some of these more intriguing findings and to encourage researchers in the fields of memory and decision making to incorporate handedness as a variable in future research.

Civil litigation involving the forensic neuropsychiatric evaluation of a personal injury case requires an assessment of damages and causation. The expert witness is obliged to integrate data from three critical sources of information: the review of records; the results of neuropsychological testing; and the findings from the clinical examination. In civil litigation involving a personal injury claim, the expert witness can be expected to address causation and prognosis of any neuropsychiatric damages. We discuss the undertaking of a forensic neuropsychiatric evaluation, psychiatric disorders often encountered in personal injury litigation, provide case vignettes and describe a number of special types of forensic neuropsychiatric evaluations, for example, Workers' Compensation, VA Disability and Social Security Disability.

Objective: This study was designed to evaluate the effect of limited English proficiency (LEP) on neurocognitive profiles. Method: Romanian (LEP-RO; n = 59) and Arabic (LEP-AR; n = 30) native speakers were compared to Canadian native speakers of English (NSE; n = 24) on a strategically selected battery of neuropsychological tests. Results: As predicted, participants with LEP demonstrated significantly lower performance on tests with high verbal mediation relative to US norms and the NSE sample (large effects). In contrast, several tests with low verbal mediation were robust to LEP. However, clinically relevant deviations from this general pattern were observed. The level of English proficiency varied significantly within the LEP-RO and was associated with a predictable performance pattern on tests with high verbal mediation. Conclusions: The heterogeneity in cognitive profiles among individuals with LEP challenges the notion that LEP status is a unitary construct. The level of verbal mediation is an imperfect predictor of the performance of LEP examinees during neuropsychological testing. Several commonly used measures were identified that are robust to the deleterious effects of LEP. Administering tests in the examinee's native language may not be the optimal solution to contain the confounding effect of LEP in cognitive evaluations. [ABSTRACT FROM AUTHOR]

Deficits in episodic verbal memory are commonly observed in persons with HIV (PWH) disease, in whom they are characterized by dysregulation of the executive aspects of encoding and retrieval and adversely impact everyday functioning. Deficits in episodic visual memory are also apparent in PWH, but we know less about their cognitive architecture. This study used the Boston Qualitative Scoring System (BQSS) for the Rey-Osterrieth Complex Figure (ROCF) to examine visual learning and recall in 43 individuals without HIV and 141 PWH who completed a full research neuropsychological, psychiatric, and medical assessment. A mixed model covarying for education and estimated verbal IQ showed that participants with HIV-associated neurocognitive disorders (HAND) performed worse than PWH without neurocognitive disorders and HIV- participants at comparable medium-to-large effect sizes across the Copy, Immediate, and Delayed trials of the BQSS-ROCF, suggesting a primary encoding deficit. A component process analysis of the BQSS-ROCF Copy Trial revealed that participants with HAND had specific difficulties with configural accuracy, cluster accuracy, and cluster placement. Within the PWH sample, measures of motor coordination and executive functions emerged as independent predictors of BQSS-ROCF Copy Trial performance. Findings extend prior research by showing that HAND may be associated with a primary encoding deficit for complex visuomotor learning and memory tasks that is driven by a combination of visuospatial, motor, and executive difficulties.

- Abstract
• What is the primary question addressed by this study? How accurate are self-assessments of cognitive performance and do they vary across different cognitive assessment strategies and human immunodeficiency virus and mild cognitive impairment (MCI) status. • What is the main finding of this study? No effects of human immunodeficiency virus status were found for cognitive performance or self-assessment of performance. MCI status was associated with poorer performance on testing and overestimations in self-assessments. • What is the meaning of the finding? Both MCI+ and MCI- participants misestimated their performance. Thus, cognitive challenges can only be validly confirmed with performance-based assessments, although comparing performance to self-assessments may identify important individual-level challenges. Self-assessment of cognitive abilities can be an important predictor of clinical outcomes. This study examined impairments in self-assessments of cognitive performance, assessed with traditional neuropsychological assessments and novel virtual reality tests among older persons with and without human immunodeficiency virus (HIV) and mild cognitive impairment (MCI). One hundred twenty-two participants (82 persons with HIV; 79 MCI+) completed a traditional neuropsychological battery, DETECT virtual reality cognitive battery, and self-reported their general cognitive complaints, depressive symptoms, and perceptions of DETECT performance. Relationships between DETECT performance and self-assessments of performance were examined as were the correlations between general cognitive complaints and performance. These relations were evaluated across HIV and MCI status, considering the associations of depressive symptoms, performance, and self-assessment. We found no effect of HIV status on objective performance or self-assessment of DETECT performance. However, MCI+ participants performed worse on DETECT and traditional cognitive tests, while also showing a directional bias towards overestimation of their performance. MCI- participants showed a bias toward underestimation. Cognitive complaints were reduced compared to objective performance in MCI+ participants. Correlations between self-reported depressive symptoms and cognitive performance or self-assessment of performance were nonsignificant. MCI+ participants underperformed on neuropsychological testing, while overestimating performance. Interestingly, MCI- participants underestimated performance to approximately the same extent as MCI+ participants overestimated. Practical implications include providing support for persons with MCI regarding awareness of limitations and consideration that self-assessments of cognitive performance may be overestimated. Similarly, supporting older persons without MCI to realistically appraise their abilities may have clinical importance. [ABSTRACT FROM AUTHOR]

Digital voice recordings can offer affordable, accessible ways to evaluate behavior and function. We assessed how combining different low-level voice descriptors can evaluate cognitive status. Using voice recordings from neuropsychological exams at the Framingham Heart Study, we developed a machine learning framework fusing spectral, prosodic, and sound quality measures early in the training cycle. The model's area under the receiver operating characteristic curve was 0.832 (±0.034) in differentiating persons with dementia from those who had normal cognition. This offers a data-driven framework for analyzing minimally processed voice recordings for cognitive assessment, highlighting the value of digital technologies in disease detection and intervention.

Objective: We investigated the diagnostic accuracy of the Clock Drawing Test (CDT) in discriminating Mild Cognitive Impairment (MCI) and dementia from normal cognition. Additionally, its clinical utility in predicting the transition from normal cognition to MCI and dementia over the course of several years was explored. Method: In total, 1037 older adults (633 women) who completed the CDT in a baseline assessment were drawn from the population-based HELIAD cohort. Among these, 848 participants were identified as cognitively normal, 142 as having MCI and 47 with dementia during the baseline assessment. Of these individuals, 565 attended the follow-up assessment (mean interval: 3.21 years). ROC curve and binary logistic regression analyses were performed. Results: The CDT exhibited good diagnostic accuracy for the discrimination between dementia and normal cognition (AUC =.879, SN =.813, SP =.778, LR+ = 3.66, LR- =.240, <.001, d = 1.655) and acceptable diagnostic accuracy for the discrimination between dementia and MCI (AUC=.761, SN=.750, SP=.689, LR+ = 2.41, LR- =.362, p <.001, d = 1.003). We found limited diagnostic accuracy, however, for the discrimination between MCI and normal cognition (AUC =.686, SN =.764, SP =.502, LR+ = 1.53, LR- =.470, p <.001, d =.685). Moreover, the CDT significantly predicted the transition from normal cognition to dementia [Exp(B)= 1.257, p =.022], as well as the transition from MCI to normal cognition [Exp(B) = 1.334, p =.023] during the longitudinal investigation. Conclusions: The CDT is a neuropsychological test with acceptable diagnostic accuracy for the discrimination of dementia from MCI and normal cognition. Furthermore, it has an important predictive value for the transition from normal cognition to dementia and from MCI to normal cognition. [ABSTRACT FROM AUTHOR]

Objectives: Dementia assessment includes cognitive and behavioral testing with informant verification. Conventional testing is resource-intensive, with uneven access. Online unsupervised assessments could reduce barriers to risk assessment. The aim of this study was to assess the relationship between informant-rated behavioral changes and participant-completed neuropsychological test performance in older adults, both measured remotely via an online unsupervised platform, the Brain Health Registry (BHR).Design: Observational cohort study.Setting: Community-dwelling older adults participating in the online BHR. Informant reports were obtained using the BHR Study Partner Portal.Participants: The final sample included 499 participant-informant dyads.Measurements: Participants completed online unsupervised neuropsychological assessment including Forward Memory Span, Reverse Memory Span, Trail Making B, and Go/No-Go tests. Informants completed the Mild Behavioral Impairment Checklist (MBI-C) via the BHR Study Partner portal. Cognitive performance was evaluated in MBI+/- individuals, as was the association between cognitive scores and MBI symptom severity.Results: Mean age of the 499 participants was 67, of which 308/499 were females (61%). MBI + status was associated with significantly lower memory and executive function test scores, measured using Forward and Reverse Memory Span, Trail Making Errors and Trail Making Speed. Further, significant associations were found between poorer objectively measured cognitive performance, in the domains of memory and executive function, and MBI symptom severity.Conclusion: These findings support the feasibility of remote, informant-reported behavioral assessment utilizing the MBI-C, supporting its validity by demonstrating a relationship to online unsupervised neuropsychological test performance, using a previously validated platform capable of assessing early dementia risk markers.

Previous research has suggested that up to 45% of people develop clinically significant depressive symptoms post-COVID. This study sought to determine frequency, symptom profile, and clinical correlates of depression post-COVID.Methods: Seventy-five participants who had recovered from COVID-19 underwent neurocognitive, psychiatric, medical, and cognitive testing/screening. The primary measures of interest in this report included the Patient Health Questionnaire (PHQ-9), a 9-item depression-screening tool, and the Endicott Quality of Life Enjoyment and Satisfaction Questionnaire.Results: One-third of study participants screened as positive on the PHQ-9 for clinically significant depression, with the most commonly reported symptom being fatigue, followed by sleep disturbance and poor concentration. Also reported were decreased satisfaction in employment, sexual life, and mood. Depressed patients described greater illness severity during COVID-19 infection and subjective cognitive impairment, which was not found on neurocognitive testing. The only significant predictor of depression was COVID-19 illness severity.Limitations: A significant portion of participants was a clinical population with specific post-COVID complaints and was predominately comprised of white females. Formal psychiatric evaluation was not performed.Conclusion: Many individuals may experience depression after COVID-19 infection, with symptoms appearing to be predominately somatic in nature and correspond with COVID-19 illness severity.Keywords: COVID-19, depression, quality of life, neuropsychological testing

Purpose of reviewWhile traditional neuropsychological tests are the gold standard in screening for HIV-related cognitive impairment, computerized neuropsychological assessment devices (CNADs) offer an alternative to these time- and resource-intensive batteries and may prove to be particularly useful for remote assessments or longitudinal monitoring. This review seeks to describe the benefits, limitations, and validity of CNADs in the evaluation of HIV-associated neurocognitive disorder (HAND).Recent findingsWe identified eight CNADs that have undergone validity testing for cognitive impairment in the setting of HIV. Included among these are batteries that have been modeled after the traditional neuropsychological exam, as well as others that implement new technologies, such as simulated reality and daily ecological assessments in their testing. Currently, these digital batteries do not yet have the ability to supplant gold standard neuropsychological tests in screening for HAND. However, many have the potential to become effective clinical screening tools.

There is a critical need for accessible neuropsychological testing for basic research and translational studies worldwide. Traditional in-person neuropsychological studies are inherently difficult to conduct because testing requires the recruitment and participation of individuals with neurological conditions. Consequently, studies are often based on small sample sizes, are highly time-consuming, and lack diversity. To address these challenges, in the last decade, the utilization of remote testing platforms has demonstrated promising results regarding the feasibility and efficiency of collecting patient data online. Herein, we tested the validity and generalizability of remote administration of the Montreal Cognitive Assessment (MoCA) test. We administered the MoCA to English and Hebrew speakers from three different populations: Parkinson’s disease, Cerebellar Ataxia, and healthy controls via video conferencing. First, we found that the online MoCA scores do not differ from traditional in-person studies, demonstrating convergent validity. Second, the MoCA scores of both our online patient groups were lower than controls, demonstrating construct validity. Third, we did not find differences between the two language versions of the remote MoCA, supporting its generalizability to different languages and the efficiency of collecting binational data (USA and Israel). Given these results, future studies can utilize the remote MoCA, and potentially other remote neuropsychological tests to collect data more efficiently across multiple different patient populations, language versions, and nations.

The challenge to find the best predictors of conversion from Mild Cognitive Impairment (MCI) to Alzheimer’s disease (AD) has been ongoing at least for the last decade. Nonetheless, clinicians still lack, to date, a robust predictive tool for identifying individuals who will go through this conversion. In this narrative review, we reported the sensitivity and specificity of biomarkers and neurocognitive assessment in predicting the progression from MCI to AD. Given that biomarkers do not necessarily provide a better predictive accuracy as showcased by the numbers in this study, cognitive tests seem like a more cost-effective, less invasive, and easily accessible option. They also offer the added benefit of measuring functional cognitive impairment. However, it remains clear that efforts are still needed to come up with more accurate, sensitive, and specific predictors.

BackgroundThe Direct Assessment of Functional Status (DAFS) is the only instrument validated in Brazil that assesses functionality directly with the patient. However, this clinical tool takes a long time to be administered. This limits its use in hospitals and outpatient clinics that require brief assessment instruments. Additionally, we need to count with a direct assessment because the number of older adults living alone is increasing and we thus lack reliable informants.ObjectiveThis study aimed to present the development and content validity evidence of a direct complex functionality test for older adults, the Brief Instrument for Direct Functionality Assessment (BIDFA).MethodA total sample of 30 older adults and eight expert judges took part in the study stages. The BIDFA construction stages were: (1) literature review of functionality instruments; (2) development of seven ecological tasks to evaluate the performance of daily complex activities with the older adults; (3) content analysis by eight expert judges; (4) pilot study with 30 older adults; (5) the ecological analysis of items; (6) focus group analysis; and (7) final version of the BIDFA.ResultsThe BIDFA had evidence of content validity with an agreement index of 96.5%. The final version of BIDFA was left with six domains of complex functionality divided into semantic memory and time orientation; shopping skills; executive attention, math and finance skills; organization; planning and procedural memory; and problem-solving. The complex functionality score by BIDFA ranges from 0 to 100 points.ConclusionThe BIDFA was found to have good content validity by the expert judges and by the ecological analysis of the items by the older adults. The new instrument is expected to help assess the functional status of older adults, in an abbreviated context including complex functionality demands, with a wider range of total and subdomain scores.

Objective: The comparison of baseline neuropsychological test results with post-concussion neuropsychological test results is a common practice to assess the aftermath of a sport-related concussion. The effectiveness of this approach is compromised when invalid baseline test performances occur. The present study was designed to assess the prevalence of invalid baseline test results of high school athletes, using the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT). Method: A large sample of 8938 high school athletes' baseline test data were examined, including the four ImPACT Composite scores and three sets of embedded invalid indices: five ImPACT Invalidity Indicators, four ImPACT sandbagging red flags, and two ImPACT sandbagging subtest flags. Results: There were 8394 (93.91%) Valid scorers, who failed no Invalidity Indicators; 544 (6.09%) Invalid scorers, who failed at least one Invalidity Indicator, 2718 (30.41%) Red Flag scorers, who had at least one Red Flag score; and 4154 (46.47%) Subtest Flag scorers, who had at least one Subtest Flag score. Of the entire sample, 4485 (54.65%) failed at least one of the invalid indices. Conclusions: As in prior studies of high school athletes, the Invalidity Indicators identified a low portion (6.09%) of the athletes with invalid baseline test results, while other invalidity measures found 30.41% to 46.48% of the athletes producing questionable test results. The high rate of invalid test findings suggested in this research calls for greater efforts to improve the accuracy of baseline test results. [ABSTRACT FROM AUTHOR]

Objective: While assessment of performance validity is essential to neuropsychological evaluations, use of performance validity tests (PVTs) in an epilepsy population has raised concerns due to factors that may result in performance fluctuations. The current study assessed whether specificity was maintained at previously suggested cutoffs in a confirmed epilepsy population on the Warrington Recognition Memory Test (WRMT) – Words and Test of Memory Malingering (TOMM). Method: Eighty-two confirmed epilepsy patients were administered the WRMT-Words and TOMM as part of a standardized neuropsychological evaluation. Frequency tables were utilized to investigate specificity rates on these two PVTs. Results: The suggested WRMT-Words Accuracy Score cutoff of ≤42 was associated with a specificity rate of 90.2%. Five out of the 8 individuals falling below the Accuracy Score cutoff scored 42, suggesting specificity could be further improved by slightly lowering the cutoff. The WRMT-Words Total Time cutoff of ≥207 seconds was associated with 95.1% specificity. A TOMM Trial 1 cutoff of <40 was associated with 93.9% specificity, while the established cutoff of <45 on Trial 2 and the Retention Trial yielded specificity rates of 98.6% and 100.0%, respectively. Conclusions: Our findings demonstrate acceptable performance on two PVTs in a select confirmed epilepsy population without a history of brain surgery, active seizures during testing, and/or low IQ, irrespective of various factors such as seizure type, seizure lateralization/localization, and language lateralization. The possible presence of interictal discharges were not controlled for in the current study, which may have contributed to reduced PVT performances. [ABSTRACT FROM AUTHOR]

TEST validity , *ITEM response theory - Abstract
Objectives: Data from neurocognitive assessments may not be accurate in the context of factors impacting validity, such as disengagement, unmotivated responding, or intentional underperformance. Performance validity tests (PVTs) were developed to address these phenomena and assess underperformance on neurocognitive tests. However, PVTs can be burdensome, rely on cutoff scores that reduce information, do not examine potential variations in task engagement across a battery, and are typically not well-suited to acquisition of large cognitive datasets. Here we describe the development of novel performance validity measures that could address some of these limitations by leveraging psychometric concepts using data embedded within the Penn Computerized Neurocognitive Battery (PennCNB). Methods: We first developed these validity measures using simulations of invalid response patterns with parameters drawn from real data. Next, we examined their application in two large, independent samples: 1) children and adolescents from the Philadelphia Neurodevelopmental Cohort (n = 9498); and 2) adult servicemembers from the Marine Resiliency Study-II (n = 1444). Results: Our performance validity metrics detected patterns of invalid responding in simulated data, even at subtle levels. Furthermore, a combination of these metrics significantly predicted previously established validity rules for these tests in both developmental and adult datasets. Moreover, most clinical diagnostic groups did not show reduced validity estimates. Conclusions: These results provide proof-of-concept evidence for multivariate, data-driven performance validity metrics. These metrics offer a novel method for determining the performance validity for individual neurocognitive tests that is scalable, applicable across different tests, less burdensome, and dimensional. However, more research is needed into their application. [ABSTRACT FROM AUTHOR]

Depressed patients report more severe cognitive impairment than is detectable by neuropsychological tests because they may underestimate their cognitive performance. Alternatively, it is possible that cognitive impairment primarily occurs under everyday life conditions as referred to in most questionnaires. The aim of the present study is to investigate the validity of self-reports in patients with major depression in order to better understand the pronounced impairment in self-reports. We investigated 58 patients with major depression and 28 heathy control participants. We administered the "Screen for Cognitive Impairment in Psychiatry" (SCIP) to assess cognitive performance, the "Questionnaire for Cognitive Complaints" (FLei), and the newly developed scale for "Self-Perception of Cognitive Performance in everyday life and test settings" to ask for the self-assessed cognitive performance in everyday life and in a test situation more specifically. Depressed patients showed an inferior test performance and reported much more general everyday life related cognitive problems compared to healthy participants. When asked more specifically for their cognitive performance in the test-situation compared to others and compared to everyday life, they did not report more test-related and everyday life related impairment than healthy participants did. Results might be influenced by comorbidity. These results have implications for the assessment of subjective cognitive performance of depressed patients and shed light on the negative effects of general versus more specific recall of autobiographical information. • Depressed patients showed an inferior test performance. • They reported much more general everyday life related cognitive problems. • Development of a novel scale to ask specifically for own test performance • When asked more specifically they do not over-report cognitive deficits.
