Patterns of prospective memory errors differ in persons with multiple sclerosis

ABSTRACT Introduction Prospective memory (PM) deficits have been documented in multiple sclerosis (MS). This study aimed to explore the specific types of errors made by persons with MS (PwMS), including differences between PwMS and healthy controls (HC) and PwMS who do and do not have impairments in processing speed and/or verbal learning and memory. Method PwMS (n = 111) and HC (n = 75) completed the Memory for Intentions Test (MIST), an objective measure of PM that has five types of errors that can be coded (PM failure, task substitution, loss of content, loss of time, and random errors). The number and types of PM errors were calculated for the overall MIST and six subscales, which break down performance by types of delay (2-Minute and 15-Minute), cue (Time and Event), and response (Verbal and Action). Impairment was defined as performing < 1.5 SD on either the Symbol Digit Modalities Test (SDMT) or Rey Auditory Verbal Learning Test (RAVLT). Bivariate analyses were used to examine group differences, with post-hoc pairwise comparisons with Bonferroni corrections. Results Nearly 93% of PwMS made at least one PM error, compared to 76% of HC (V = .24, p = .001). The most commonly made PM error by PwMS was loss of content errors (45.0%). PwMS made significantly more task substitution errors (26.4% vs. 7.6%, p < .001) and fewer loss of time errors (9.5% vs. 21.2%, p < .001) than HC. Impaired PwMS made more errors than non-impaired PwMS, specifically PM failures on time-based tasks. Conclusions PM errors are common in PwMS, particularly when there are longer delays and time-based cues. Not only do PwMS make more errors than demographically similar HC, but they exhibit different cognitive process failures.

Evaluation of Patients with Multiple Sclerosis in Terms of Memory, Attention, Executive Functions, Fine Motor Movement and the Association thereof with Magnetic Resonance Imaging Results

Aim: This study aimed to review cognitive function and fine motor skills in patients with multiple sclerosis (MS) and investigate the association with magnetic resonance imaging (MRI) results. Material and Methods: The study included 22 patients diagnosed with relapsing-remitting MS and 22 controls. Participants underwent neuropsychological tests, including the Stroop test, Rey auditory verbal learning test (RAVLT), line bisection test (LBT), serial reaction time test (SRTT), and finger tapping test (FTT). The relationship between severity of disease, MRI, and test performance was investigated. Results: It was determined that the patients were lateralized to the right in the LBT data, while the control group was lateralized to the left (p=0.024). On cognitive tests, there was no significant difference in Stroop test results (p=0.134), but the mean overall RAVLT of the patient group was significantly lower than that of the control group (p

Impact of Repetitive Transcranial Magnetic Stimulation on Cognitive and Psychiatric Dysfunction in Patients with Fibromyalgia: A Double-Blinded, Randomized Clinical Trial

Few randomized controlled trials have reported that repetitive transcranial magnetic stimulation (rTMS) has controversial results for managing multiple domains of fibromyalgia-related symptoms. This work aimed to evaluate the effect of low-frequency rTMS over the right dorsolateral prefrontal area (DLPFC) on the Fibromyalgia Impact Questionnaire (FIQ) concerning psychiatric and cognitive disorders. Forty-two eligible patients with fibromyalgia (FM) were randomized to have 20 sessions of active or sham rTMS (1 Hz, 120% of resting motor threshold with a total of 1200 pules/session) over the right DLPFC. All participants were evaluated at baseline, post sessions, and 3 months after sessions with the FIQ, Hamilton depression, and anxiety rating scales (HDRS and HARS), Montreal Cognitive Assessment (MoCA), Rey Auditory Verbal Learning Test (RAVLT), Tower of London test (TOL), the Trail Making, and Digit Span Tests. Both groups showed improvement in most rating scales at 1 and 3 months follow-up, with greater improvement in the active group, with significant correlation between FIQ cognitive rating scales, including RAVLT and TOL. Twenty sessions of low-frequency rTMS over the right DLPFC can improve FIQ scores regarding the psychiatric and cognitive symptoms of medicated patients with FM to a greater extent than sham. Changes in RAVLT and TOL correlated with changes in FIQ results.

The hippocampus as a structural and functional network epicentre for distant cortical thinning in neurocognitive aging

Alterations in grey matter (GM) and white matter (WM) are associated with memory impairment across the neurocognitive aging spectrum and theorised to spread throughout brain networks. Functional and structural connectivity (FC,SC) may explain widespread atrophy. We tested the effect of SC and FC to the hippocampus on cortical thickness (CT) of connected areas. In 419 (223 F) participants (agemean=73 ± 8) from the Alzheimer’s Disease Neuroimaging Initiative, cortical regions associated with memory (Rey Auditory Verbal Learning Test) were identified using Lasso regression. Two structural equation models (SEM), for SC and resting-state FC, were fitted including CT areas, and SC and FC to the left and right hippocampus (LHIP,RHIP). LHIP (β=-0.150,p=<.001) and RHIP (β=-0.139,p=<.001) SC predicted left temporopolar/rhinal CT; RHIP SC predicted right temporopolar/rhinal CT (β=-0.191,p=<.001). LHIP SC predicted right fusiform/parahippocampal (β=-0.104,p=.011) and intraparietal sulcus/superior parietal CT (β=0.101,p=.028). Increased RHIP FC predicted higher left inferior parietal CT (β=0.132,p=.042) while increased LHIP FC predicted lower right fusiform/parahippocampal CT (β=-0.97; p=.023). The hippocampi may be epicentres for cortical thinning through disrupted connectivity.

Assessment of memory deficits in psychiatric disorders: A systematic literature review

Memory deficits are observed across psychiatric disorders ranging from the prodrome of psychosis to common mental disorders such as anxiety, depression, and dissociative disorders. Memory deficits among patients recovering from psychiatric disorders could be directly related to the primary illness or secondary to the adverse effect of a treatment such as Electroconvulsive Therapy (ECT). The trouble in the meaningful integration of working-memory and episodic memory is the most commonly affected domain that requires routine assessments. An update on the recent trends of methods of assessment of memory deficits is the first step towards understanding and correcting these deficits to target optimum recovery. A systematic literature search was conducted from October 2018 to October 2022 to review the recent methods of assessment of memory deficits in psychiatric disorders. The definition of ‘Memory deficit’ was operationalized as ‘selective processes of memory, commonly required for activities of daily living, and affected among psychiatric disorders resulting in subjective distress and dysfunction’. We included 110 studies, most of them being conducted in western countries on patients with schizophrenia. Other disorders included dementia and mild cognitive impairment. Brief Assessment of Cognition in Schizophrenia, Cambridge Automated Neuropsychological Test Battery, California Verbal Learning Test, Trail Making Test Part A and B, Rey Auditory Verbal Learning Test, Wechsler Memory Scale, Wechsler Adults Intelligence Scale-IV were the most common neuropsychological assessments used. Mini-Mental State Examination and Montreal Cognitive Assessment were the most common bedside assessment tools used while Squire Subjective Memory Questionnaire was commonly used to measure ECT-related memory deficits. The review highlights the recent developments in the field of assessment of memory deficits in psychiatric disorders. Findings recommend and emphasize routine assessment of memory deficits among psychiatric disorders in developing countries especially severe mental illnesses. It remains interesting to see the role of standardized assessments in diagnostic systems given more than a decade of research on memory deficits in psychiatric disorders.

Toxic-Induced Encephalopathy Following Chemsex in a Young HIV-Positive Male: A Complex Case of Acute Cognitive Impairment with Anterograde Amnesia and Behavioral Alterations.

A broadened clinical spectrum of concomitant complications emerges among the escalating incidence of substance use, particularly within the 'chemsex' context. This case exemplifies the profound neurotoxic repercussions and neurological risk of chemsex in a young HIV-positive male and addresses the multifaceted challenges of such evolving paradigms in substance utilization. After consuming cannabis, poppers, methamphetamine, and cocaine, a 28-year-old HIV-positive male exhibited significant neurological and cognitive impairment. The initial presentation included dysarthria and profound anterograde amnesia. Laboratory findings showed leukocytosis with a PCR of 3mg/dl - elevated cerebrospinal fluid protein levels with no cells. Urine toxicology returned positive for cannabis and amphetamines. A brain CT scan revealed bilateral and symmetrical hippocampi and pale globes hypodensity, indicative of toxic-metabolic encephalopathy. MRI further identified lesions in the globus pallidus, cerebellum, and hippocampi. Following the detection of toxic encephalopathy, Initial neuropsychological was performed screening using the Montreal Cognitive Assessment (MoCA), which highlighted immediate memory deficits. An in-depth neuropsychological assessment conducted 3weeks later included the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV), the Rey Auditory Verbal Learning Test (RAVLT), and tests for visuospatial skills, motor functions, and memory recall. The evaluations revealed pronounced anterograde amnesia, persistent long-term memory inconsistencies, and notable executive function challenges, detailed in Table 1. The detailed analysis of this case underpins the severe neurological consequences that can manifest from heavy substance use. Comprehensive diagnostic evaluations, including neuroimaging and neuropsychological assessments, are crucial in elucidating the full spectrum of substance-induced cognitive impairments. There is an urgent need for enhanced public awareness and preventative measures, especially in the context of chemsex, to bring forth multifaceted health, social, and government implications that modern society must adeptly navigate.

145 Encoding Brain Dynamics: Neuropsychological Test Scores as Predictors of iEEG Spectral Features in Epilepsy

INTRODUCTION: Intracranial EEG is a valuable tool for investigating the neural mechanisms underlying medically refractory epilepsy (MRE). Despite the advances made in understanding the condition, there is a lack of research exploring the relationship between iEEG data and neuropsychological test performance in MRE patients. METHODS: We performed a retrospective analysis of resting-state iEEG data from 70 MRE patients, extracting spectral features from 4.4 million 10-second time windows across 5201 electrodes. Using MATLAB and FieldTrip toolbox, we processed the data and used two brain atlases for probabilistic electrode assignment. Neuropsychological test scores were corrected for demographic factors. Relationships between preoperative neuropsychological test scores and spectral features were explored using nested hierarchical generalized linear mixed effects (GLME) models, focusing on the hippocampus. RESULTS: We found significant associations between neuropsychological tests and hippocampal power spectral densities (PSDs). Rey Auditory verbal learning test (RAVLT) recognition correct and short-term retention percentages were significantly associated with relative power (RP) in the beta-range (p &lt; 0.05, FDR-corrected). The Boston naming test and Trail Making Test (TMT)-A finishing time showed significant associations with high-beta/low-gamma PSD (p &lt; 0.05, FDR-corrected). TMT-B errors are positively correlated with delta/theta RP (p &lt; 0.05, FDR-corrected). CONCLUSIONS: Our study provides novel insights into the relationship between iEEG spectral features and neuropsychological test performance in MRE patients. The findings suggest that the heterogeneity in spectral features may explain relevant cognitive performance, highlighting the biological basis and circuits of neuropsychological testing.

Trajectories in depressive symptoms and midlife brain health

Depressive symptoms may either be a risk factor or prodromal to dementia. Investigating this association in midlife may help clarify the role of depression in cognitive aging. We aimed to identify trajectories in depressive symptoms in early to mid-life and related cognitive and brain outcomes in midlife. This study includes 3944 Black and White participants (ages 26−45 years at baseline) from the Coronary Artery Risk Development in Young Adults (CARDIA) study with 20 years of follow-up. Depressive symptoms were assessed using the Center for Epidemiological Studies Depression scale at five time points over 20 years. Growth mixture modeling (GMM) was used to identify depressive symptom trajectories. Participants completed a neuropsychological battery 20 years after baseline, including the Digit Symbol Substitution Test (DSST), Rey-Auditory Verbal Learning Test (RAVLT), Stroop Test, Montreal Cognitive Assessment (MoCA), and category and letter fluency tests. A sub-sample of participants (n = 662) underwent brain magnetic resonance imaging (MRI) to characterize gray matter volumes and white matter hyperintensities (WMHs). We identified four classes of depressive symptom trajectories: a “declining” class (n = 286, 7.3%) with initially high symptoms and subsequent decline, a class with consistently high symptoms (“steady high”; n = 264, 6.7%), a class with late increases in symptoms (“increasing”; n = 277, 7%), and a class with consistently low symptoms (“steady low”; n = 3117, 79.0%). The steady high and the increasing classes had poorer performance on all cognitive tests, while the declining class had poorer performance on the DSST, verbal fluency, and MoCA. Compared to the steady low symptom class, the steady high class had lower volumes in the entorhinal cortex (β: −180.80, 95% CI: −336.69 to −24.91) and the amygdala (β: −40.97, 95% CI: −74.09 to −7.85), the increasing class had more WMHs (β: 0.55, 95% CI: 0.22 to 0.89), and the declining class was not significantly different in any brain measures. Trajectories in depressive symptoms in young to mid-adulthood show distinct cognitive and brain phenotypes in midlife. Steady high depressive symptoms may represent a group that is at risk for dementia, whereas increasing symptoms in midlife may be associated with white matter damage.

Comparison of cognitive functions in individuals with primary psychosis and substance-induced psychotic disorders

ABSTRACT Background Cognitive dysfunctions are common in patients with primary psychosis disorder (PPD) and substance-induced psychotic disorder (SIPD), and this problem is very important in the course of their treatment and relapse. The present research was done to study the cognitive functions in the patients suffering from PPD compared to the patients with SIPD. Methods In this analytical study, the study population included all patients admitted to Farabi Hospital, Kermanshah, Iran, diagnosed with PPD and SIPD, whose cognitive functions were compared using the Rey Auditory Verbal Learning Test (RAVLT), Symbol Digit Modalities Test (SDMT) and Verbal Fluency Test (VFT). Results Only the mean number of words in the first list that the patient was unable to identify (Miss) distinguished the two groups in terms of the mean RAVLT scores. Due to the number of accurate answers in the SDMT and the speed of visual search, there was no discernible difference between the PPD and SIPD groups. The results showed a significant difference between the two groups due to the total number of correct VFT word in two parts of letters and categories. Conclusion The results of the present study can be used in the treatment and rehabilitation of PPD and SIPD patients.

Cognitive profile in cerebral small vessel disease: comparison between cerebral amyloid angiopathy and hypertension-related microangiopathy

Cerebral amyloid angiopathy (CAA) is recognized as a cause of cognitive impairment, but its cognitive profile needs to be characterized, also respect to hypertension-related microangiopathy (HA). We aimed at comparing difference or similarity of CAA and HA patients’ cognitive profiles, and their associated factors. Participants underwent an extensive clinical, neuropsychological, and neuroimaging protocol. HA patients (n = 39) were more frequently males, with history of vascular risk factors than CAA (n = 32). Compared to HA, CAA patients presented worse performance at MoCA (p = 0.001) and semantic fluency (p = 0.043), and a higher prevalence of amnestic MCI (46% vs. 68%). In univariate analyses, multi-domain MCI was associated with worse performance at MoCA, Rey Auditory Verbal Learning Test (RAVLT), and semantic fluency in CAA patients, and with worse performance at Symbol Digit Modalities Test (SDMT) and phonemic fluency in HA ones. In multivariate models, multi-domain deficit remained as the only factor associated with RAVLT (β = − 0.574) in CAA, while with SDMT (β = − 0.364) and phonemic fluency (β = − 0.351) in HA. Our results highlight different patterns of cognitive deficits in CAA or HA patients. While HA patients’ cognitive profile was confirmed as mainly attentional/executive, a complex cognitive profile, characterized also by deficit in semantic memory, seems the hallmark of CAA patients.

Machine Learning Predicts Conversion from Normal Aging to Mild Cognitive Impairment Using Medical History, APOE Genotype, and Neuropsychological Assessment.

Identifying individuals at risk for mild cognitive impairment (MCI) is of urgent clinical need. This study aimed to determine whether machine learning approaches could harness longitudinal neuropsychology measures, medical data, and APOEɛ4 genotype to identify individuals at risk of MCI 1 to 2 years prior to diagnosis. Data from 676 individuals who participated in the 'APOE in the Predisposition to, Protection from and Prevention of Alzheimer's Disease' longitudinal study (N = 66 who converted to MCI) were utilized in supervised machine learning algorithms to predict conversion to MCI. A random forest algorithm predicted conversion 1-2 years prior to diagnosis with 97% accuracy (p = 0.0026). The global minima (each individual's lowest score) of memory measures from the 'Rey Auditory Verbal Learning Test' and the 'Selective Reminding Test' were the strongest predictors. This study demonstrates the feasibility of using machine learning to identify individuals likely to convert from normal cognition to MCI.

Cognitive assessment to optimize prediction of functional outcome in subacute hip fracture: a short-term prospective study.

Cognitive impairment is a long-known negative prognostic factor after hip fracture. Cognition is usually screened by a single easy-to-administer bedside tool, but recent studies have shown that screening tests may be not enough to rule out cognitive impairment with an unfavorable prognostic role. Unfortunately, data on outcome prediction by further cognitive assessments is sparse. We focused on patients with subacute hip fracture defined cognitively intact or mildly impaired on the screening evaluation performed by the Short Portable Mental Status Questionnaire (SPMSQ). We hypothesized that each of 3 further cognitive tests could independently predict activities of daily living, with optimal prediction of function obtained by performing all three the tests. Short-term prospective study. Rehabilitation ward. Inpatients with subacute hip-fracture. Three cognitive tests were performed on admission to rehabilitation in the patients who made ≤4 errors on the SPMSQ: Montreal Cognitive Assessment (MoCA), Rey Auditory Verbal Learning Test (RAVLT, immediate and delayed recall) and Frontal Assessment Battery (FAB). We assessed activities of daily living by the Barthel index. Successful rehabilitation was defined with a Barthel Index Score ≥85. Each of the three cognitive tests assessed before rehabilitation significantly predicted the Barthel index scores measured at the end of the rehabilitation course in our sample of 280 inpatients. However, only the MoCA score retained its significant predictive role when the scores from the three tests were included together as independent variables in a multiple regression model, with adjustments for a panel of potential confounders (P=0.007). The adjusted odds ratio to achieve successful rehabilitation for a seven-point change in MoCA score was 1.98 (CI 95% from 1.02 to 3.83; P=0.042). Contrary to our hypothesis, MoCA but not RAVLT and FAB retained the prognostic role when the scores from the three tests were evaluated together as potential predictors of functional ability in activities of daily living. In the presence of a normal (or mildly altered) score on the SPMSQ in subacute hip fracture, MoCA scores improve prediction of activities of daily living and should be routinely performed.

Associations of Polycystic Ovary Syndrome With Indicators of Brain Health at Midlife in the CARDIA Cohort.

Polycystic ovary syndrome (PCOS) is a common reproductive disorder associated with an adverse cardiometabolic profile early in life. Increasing evidence links cardiovascular risk factors, such as diabetes and hypertension, to accelerated cognitive aging. However, less is known about PCOS and its relationship to brain health, particularly at midlife. Our goal was to investigate possible associations between PCOS and midlife cognitive function and brain MRI findings in an ongoing prospective study. We used data from the Coronary Artery Risk Development in Young Adults (CARDIA) study, a geographically diverse prospective cohort study of individuals who were 18-30 years at baseline (1985-1986) and followed for 30 years. We identified women with PCOS from an ancillary study (CARDIA Women's study (CWS); n = 1,163) as those with elevated androgen levels and/or hirsutism in conjunction with symptoms of oligomenorrhea. At year 30, participants completed cognitive testing, including the Montreal Cognitive Assessment, Rey Auditory Verbal Learning Test (RAVLT) (verbal learning and memory), Digit Symbol Substitution Test (processing speed and executive function), Stroop test (attention and cognitive control), and category and letter fluency tests (semantics and attention). A subset completed brain MRI to assess brain structure and white matter integrity. Multivariable linear regression models estimated the association between PCOS and outcomes, adjusting for age, race, education, and study center. Of the 1163 women in CWS, 907 completed cognitive testing, and of these, 66 (7.1%) met criteria for PCOS (age 54.7 years). Women with and without PCOS were similar for age, BMI, smoking/drinking status, and income. At year 30, participants with PCOS performed lower (mean z score; 95% CI) on Stroop (-0.323 (-0.69 to -7.37); p = 0.008), RAVLT (-0.254 (-0.473 to -0.034); p = 0.002), and category fluency (-0.267 (-0.480 to -0.040); p = 0.02) tests. Of the 291 participants with MRI, 25 (8.5%) met PCOS criteria and demonstrated lower total white matter fractional anisotropy, a measure of white matter integrity (coefficient (95% CI) -0.013 (-0.021 to -0.005); p = 0.002), though not abnormal white matter. Our results suggest that women with PCOS have lower cognitive performance and lower white matter integrity at midlife. Additional research is needed to confirm these findings and to determine potential mechanistic pathways including potential modifiable factors.

Trajectories of cognitive decline in different domains prior to AD onset in persons with mild cognitive impairment

ObjectivesTo explore the trajectories and the change-points of global and five domain-specific cognitive functions before the onset of Alzheimer's disease (AD). MethodsData was retrieved from the Alzheimer's Disease Neuroimaging Initiative with follow-up from 2005 to 2022. Participants with mild cognitive impairment (MCI) at baseline and those who progressed to AD during follow-up were included. The time of AD onset was defined as the visit time when participant was first diagnosed as AD during follow-up. Global and five domain-specific cognitive functions (immediate memory, visuospatial ability, language, processing speed and executive function) were assessed by Mini-Mental State Examination, Immediate recalling trials of Rey Auditory Verbal Learning Test, Clock Drawing Test, Animal Fluency Test, Part A and B of Trail Making Test, respectively. Their trajectories and change-points before AD onset were explored by generalized additive mixed models and piecewise linear regression models, respectively. Results349 participants were diagnosed as MCI at baseline and converted to AD during follow-up, who were included in this study. They had been visited on an average of 4.6 times (SD = 2.1, range = 2.0–13.0), with a total of 1593 visits. Their mean baseline age and AD onset age were 74.4 (SD = 6.4, range = 60.0–88.4) and 77.0 (SD = 6.8, range = 60.5–94.7) years, respectively. Baseline age and educational year were significantly associated with global cognitive, immediate memory, language and executive function. Men presented better global cognitive function (β = 0.54, p < 0.05) but poorer immediate memory (β = −1.72, p < 0.05) than women. Immediate memory and visuospatial ability showed the earliest change-points at 4 years before the onset of AD (Note as T-4years), followed by language (T-3.5years), executive function (T-2.5 years), processing speed (T-2.0 years), and finally the global cognitive function (T-1.5years). ConclusionsThe trajectories of the six neuropsychological scores were non-linear and showed deterioration in functions over time. Immediate memory and visuospatial ability showed the earliest change-points prior to AD onset.

Exploring the Association Between Physical Activity and Cognitive Function Among People Living with Dementia.

Physical activity preserves cognitive function in people without dementia, but the relationship between physical activity and cognitive domains among people living with dementia is unclear. The objective of this study was to explore the association between physical activity and cognition domains among people living with dementia. Participants living with dementia in residential care facilities (complete case analysis: n = 24/42) completed a battery of cognitive tests (global cognition: Montreal Cognitive Assessment; executive function: Trail-Making Test, Digit Span Forward Test; perception and orientation: Benton Judgement of Line Orientation Test; language: Boston Naming Test; learning and memory: Rey Auditory Verbal Learning Test; complex attention: Digit Symbol Substitution Test). Participants wore an actigraphy monitor on their non-dominant wrist over seven days. We conducted a linear regression for total physical activity (independent variable) with race (white/black), fall risk (Morse Fall Scale), and the number of comorbidities (Functional Comorbidities Index) as covariates, and cognitive tests as variables of interest. Participants were primarily male (75%), white (87.5%), and 50%had unspecified dementia (Alzheimer's disease: 33%). Greater physical activity was associated with poorer global cognition, better executive function, and better learning and memory (ps <  0.05). Physical activity was not related to visuospatial perception, language, or complex attention. Physical activity may preserve executive function and learning and memory among people living with dementia. Wandering is more common in later stages of dementia, which may explain greater physical activity observed with lower global cognition. Regularly assessing physical activity may be useful in screening and monitoring cognitive changes.

ADAPTATION OF REY AUDITORY VERBAL LEARNING TESTFOR INDONESIA: ITS VALIDITY AND RELIABILITY

Rey’s Auditory Verbal Learning Test (RAVLT) assesses different as- pects of verbal memory and learning. This test is often used in clinical, educational, and selection contexts. We adapted the Geffen et al’ ver- sion for Indonesia and here we present sychometric properties. We tested the validity via its seven recall trials (A1 to A7), based on theore- tical constructs (e.g. the presence and recency effect) via analyses of variance and factor analyses and the test’s reliability via e.g. correlation analyses and Cronbach’s alpha. The objective of the research was to study the psychometric properties of Rey Auditory Verbal Learning Test which were adapted from Geffen et al’s to Indonesian version.Two groups of healthy participants with varying ages (16-80) and edu- cation (from Elementary school to postgraduate alumni) included 492 persons for the validation, and 50 for the test-retest reliability part of the study with a 6–14-day interval. We tested the validity via its seven recall trials, based on theoretical constructs, and factor analyses. The test’s reliability via Cronbach’s alpha test, and test-retest.The recall scores increased over trials A1 to A5. The expected position effect, primacy, and recency were found for A1 to A5. Factor analysis that the Rey Auditory Verbal Learning Test revealed three memory con- structs. The word “ibu (mother)” caused an anomaly in the position effect of the 15 words. Both Cronbach’s Alpha and the test-retest corre lations increased from low A1 to satisfying A7. Carry-over results were found in the retest.The Indonesian version of the Rey Auditory Verbal Learning Test is valid based on the recall related to the position of the words, the three clusters describing the memory of all seven trials. The score of relia- bility is only moderate for the recall score, it might be due to the test- retest procedure.

Feasibility of Remote Administration of the Uniform Data Set-Version 3 for Assessment of Older Adults With Mild Cognitive Impairment and Alzheimer's Disease.

Assess the feasibility and concurrent validity of a modified Uniform Data Set version 3 (UDSv3) for remote administration for individuals with normal cognition (NC), mild cognitive impairment (MCI), and early dementia. Participants (N =93) (age: 72.8 [8.9] years; education: 15.6 [2.5] years; 72% female; 84% White) were enrolled from the Wake Forest ADRC. Portions of the UDSv3 cognitive battery, plus the Rey Auditory Verbal Learning Test, were completed by telephone or video within ~6months of participant's in-person visit. Adaptations for phone administration (e.g., Oral Trails for Trail Making Test [TMT] and Blind Montreal Cognitive Assessment [MoCA] for MoCA) were made. Participants reported on the pleasantness, difficulty, and preference for each modality. Staff provided validity ratings for assessments. Participants' remote data were adjudicated by cognitive experts blinded to the in person-diagnosis (NC [N =44], MCI [N =35], Dementia [N =11], or other [N =3]). Remote assessments were rated as pleasant as in-person assessments by 74% of participants and equally difficult by 75%. Staff validity rating (video = 92%; phone = 87.5%) was good. Concordance between remote/in-person scores was generally moderate to good (r= .3 -.8; p< .05) except for TMT-A/OTMT-A (r= .3; p> .05). Agreement between remote/in-person adjudicated cognitive status was good (k= .61-.64). We found preliminary evidence that older adults, including those with cognitive impairment, can be assessed remotely using a modified UDSv3 research battery. Adjudication of cognitive status that relies on remotely collected data is comparable to classifications using in-person assessments.

Examining the Utility of a Multiple Group Membership Intervention for Alleviating the Effects of Age-Based Stereotype Threat on Older adults’ Memory Performance

ABSTRACT This study examined the effectiveness of a multiple group membership intervention for reducing the negative effects of age-based stereotype threat (ABST) on older adults’ objective memory performance and subjective memory concerns. Healthy older adults (N = 68) were randomly allocated to an ABST + threat-removal (ABST+TR) or ABST + active-control (ABST+AC) condition. After activating ABST, the ABST+TR condition completed a group-listing task and the ABST+AC condition completed a meal-listing task. Participants then completed the Rey Auditory Verbal Learning Test (RAVLT) and Everyday Memory Questionnaire – Revised. One significant difference was found in memory performance between conditions; specifically, after controlling for age, gender, and number of items listed, those in the ABST+TR condition performed significantly better on the RAVLT memory interference trial. Further, listing a greater number of group memberships was associated with better memory performance in the ABST+TR condition. No significant difference was found in subjective memory concerns between the ABST+TR condition and the ABST+AC condition. Overall, the current findings indicated that raising the salience of multiple group memberships offered limited protection for older adults’ cognitive test performance in the context of ABST.

Association Between Sleep Quantity and Quality in Early Adulthood With Cognitive Function in Midlife.

Growing evidence supports an association between sleep quality and risk of dementia. However, little is known about whether objectively measured sleep duration and quality influence cognition in midlife, a period of importance for understanding the direction of the association between sleep and dementia. We examined the association between sleep duration and quality, measured when participants were in their mid-30s to late 40s, and midlife cognition assessed 11 years later among Black and White adults. As part of the Coronary Artery Risk Development in Young Adults cohort study, sleep duration and quality were assessed objectively using wrist actigraphy and subjectively by Pittsburgh Sleep Quality Index (PSQI) at 2003-2005. During 2015-2016, we evaluated midlife cognition using the Digit Symbol Substitution Test (DSST), Stroop test, Rey Auditory Verbal Learning Test, Montreal Cognitive Assessment (MoCA), and Letter Fluency and Category Fluency tests. We used multivariable logistic regression to examine the association between sleep parameters and poor cognitive performance, which was defined as a score that was >1 SD below the mean score. The 526 participants (58% women and 44% Black) had a mean age of 40.1 ± 3.6 years at baseline, a mean sleep duration of 6.1 ± 1.1 hours, and mean sleep fragmentation index (calculated as the sum of the percentage of time spent moving and the percentage of immobile periods ≤1 minute) of 19.2 ± 8.1%, and 239 (45.6%) participants reported poor sleep as defined by a PSQI global score of >5. After adjustment for demographics, education, smoking, body mass index, depression, physical activity, hypertension, and diabetes, those in the highest vs lowest tertile of sleep fragmentation index had over twice the odds of having poor cognitive performance (>1 SD below the mean) on the DSST (odds ratio [OR] = 2.97; 95% CI 1.34-6.56), fluency (OR = 2.42; 95% CI 1.17-5.02), and MoCA test (OR = 2.29; 95% CI 1.06-4.94). The association between sleep fragmentation and cognitive performance did not differ by race or sex. Objective sleep duration or subjective sleep quality was not associated with cognition in midlife. Actigraphy-measured high sleep fragmentation rather than sleep duration was associated with worse cognition among middle-aged Black and White men and women. Sleep quality is important for cognitive health even as early as midlife.

Disrupted brain structural networks associated with depression and cognitive dysfunction in cerebral small vessel disease with microbleeds

Emerging evidence highlights cerebral microbleeds (CMBs) as hallmarks of cerebral small vessel disease (CSVD) underlying depression and cognitive dysfunction. This study aimed to reveal how depression and cognition-related white matter (WM) abnormalities are topologically presented, and the network-level structural disruptions associated with CMBs in CSVD. We used probabilistic diffusion tractography and graph theory to investigate brain WM network topology in CSVD patients with (n = 64, CSVD-c) and without (n = 138, CSVD-n) CMBs and 90 healthy controls. Then we evaluated the Pearson's correlations between disrupted network metrics and neuropsychological parameters. For global topology, the CSVD-c group exhibited significantly decreased global (Eglob) and local (Eloc) efficiency and increased shortest path length compared with the controls, while no significant difference was found between the CSVD-c and CSVD-n groups. For regional topology, although all groups showed highly similar hub distributions, compare with control group, the CSVD-c group exhibited significantly decreased nodal efficiency mainly in the bilateral supplementary motor area (SMA), median cingulate gyrus (DCG) and right orbital middle frontal gyrus, while the CSVD-n group showed significantly decreased nodal efficiency only in the right SMA. Notably, Eglob, Eloc and nodal efficiency of the right anterior cingulate gyrus, DCG, middle temporal gyrus and left insula showed significantly negative correlations with depression score, significantly positive correlations with Rey auditory verbal learning test and symbol digit modalities test scores in CSVD-n group, as well as significantly negative correlations with Stroop color-word test scores in CSVD-c group. The WM networks of CSVD patients are characterized by decreased global integration and local specialization, and decreased nodal efficiency highly related to depression and cognitive dysfunction in the attention, default mode network and sensorimotor regions. These findings provide new insight into the neurobiological mechanisms of CSVD and concomitant affective and cognitive disorders.
