#1
Annie L Shelton, Kim Cornish, Joanne Fielding
Carriers of a FMR1 premutation allele (between 55 and 199 CGG repeats) are at risk of developing a wide range of medical, psychiatric and cognitive disorders, including executive dysfunction. These cognitive deficits are often less severe for female premutation carriers compared to male premutation carriers, albeit similar in nature. However, it remains unclear whether female premutation carriers who exhibit executive dysfunction also report verbal learning and memory deficits like those of their male counterparts...

INTRODUCTION: Assessment of episodic memory has been traditionally used to evaluate potential cognitive impairments in senior adults. Typically, episodic memory evaluation is based on personal interviews and pen-and-paper tests. This article presents the design, development and a preliminary validation of a novel digital game to assess episodic memory intended to overcome the limitations of traditional methods, such as the cost of its administration, its intrusive character, the lack of early detection capabilities, the lack of ecological validity, the learning effect and the existence of confounding factors...

Prenatal alcohol exposure can impact both brain development and neurobehavioral function, including verbal learning and recall, although the relation between verbal recall and brain structure in this population has not been examined fully. We aimed to determine the structural neural correlates of verbal learning and recall in youth with histories of heavy prenatal alcohol exposure using a region of interest (ROI) approach. As part of an ongoing multisite project, subjects (age 10-16 years) with prenatal alcohol exposure (AE, n = 81) and controls (CON, n = 81) were tested using the CVLT-C and measures of cortical volume, surface area, and thickness as well as hippocampal volume were derived from MRI...

There are many tests of learning and memory; however, not all yield analogous results and thus are not interchangeable. This study examined the relationship between the California Verbal Learning Test-Second Edition (CVLT-II) and the Buschke Selective Reminding Test (SRT) in a stroke population. Data from stroke inpatients (N = 102) referred for rehabilitation were collected from medical records. Both tests were administered, as part of a larger neuropsychological assessment. Analyses were conducted on Z-scores from the List Total, Learning, and Long Delay Free Recall (LDFR) subscales of the two tests...

BACKGROUND: Cognitive function in people with multiple sclerosis (PwMS) is associated with gender differences and the use of smoked/ingested cannabis. OBJECTIVE: The objective of this report is to explore a possible gender-cannabis interaction associated with cognitive dysfunction in PwMS. METHODS: A retrospective analysis was undertaken of cognitive data collected from 140 PwMS. A general linear model was conducted to determine gender and cannabis effects on processing speed (SDMT), verbal (CVLT-II) and visual (BVMT-R) memory, and executive functions (D-KEFS), while controlling for age and years of education...

This study examined the role of injury-related variables, socioeconomic disadvantage, and preexisting conditions on verbal learning and memory in a sample of children with traumatic brain injury (TBI). We also explored the mediating effect of processing speed and working memory. One hundred children aged 7-16 years (M = 13.46, SD = 2.78) completed a neuropsychological assessment between 1-12 months post injury. Hierarchical multiple regression analyses were conducted on domains comprising the four-factor model of the California Verbal Learning Test-Children's Version (CVLT-C)...

BACKGROUND: Subtle age-related cognitive decline may be associated with the capacity to remain engaged in mental, physical, and social activities. Informant reports of cognitive decline potentially provide additional information to psychometric tests on change in everyday cognitive function relevant to activity engagement. OBJECTIVE: To investigate relations between decline in everyday cognitive function as assessed by informant report and activity engagement in community-dwelling older adults...

Converging evidence indicates that the prefrontal cortex is critically involved in executive control and that executive dysfunction is implicated in schizophrenia. Reduced dopamine D2/D3 receptor binding potential has been reported in schizophrenia, and the correlations with neuropsychological test scores have been positive and negative for different tasks. The aim of this study was to examine the relation between dopamine D2/D3 receptor levels with frontal and temporal neurocognitive performance in schizophrenia...

Although commonly interpreted as a marker of episodic memory during neuropsychological exams, relatively little is known regarding the neurobehavior of "total learning" immediate recall scores. Medial temporal lobes are clearly associated with delayed recall performances, yet immediate recall may necessitate networks beyond traditional episodic memory. We aimed to operationalize cognitive and neuroanatomic correlates of total immediate recall in several aging syndromes. Demographically-matched neurologically normal adults (n=91), individuals with Alzheimer's disease (n=566), logopenic variant primary progressive aphasia (PPA) (n=34), behavioral variant frontotemporal dementia (n=97), semantic variant PPA (n=71), or nonfluent/agrammatic variant PPA (n=39) completed a neurocognitive battery, including the CVLT-Short Form trials 1-4 Total Immediate Recall; a majority subset also completed a brain MRI...

INTRODUCTION: It has been demonstrated that bipolar disorder (BD) is often accompanied by cognitive deficits across all subdomains including verbal memory, attention and executive functioning. Cognitive deficits are observed both during episodes of mania or depression, as well as during the euthymic phase. It has been proposed that chronic immune-mediated inflammation in the central nervous system results in alterations in neural structures that subserve cognitive function. Kynurenine is an intermediate in the inflammatory cascade and can be peripherally measured to proxy inflammatory activity...

Objective: Memory assessment plays an important role in the diagnosis of neurodegenerative disorders. Several tests, such as the California Verbal Learning Test (CVLT), have been developed for this purpose, yet a variety of different factors can affect one's performance on such tests, the most important of which are demographic and cultural variables. The present study examined the norming process performed on the CVLT-revised and aimed to devise a new test, the Shiraz Verbal Learning Test (SVLT), to better meet the needs of speakers of Persian...

OBJECTIVE: Aging is often associated with declines in episodic memory. Reliable tracking of memory requires assessment instruments that are stable over time to better understand changes potentially attributable to neurodegenerative disease. While prior studies support the test-retest reliability of memory instruments over brief intervals, follow-up testing in clinical settings typically occurs at least one-year later. The present study evaluated the long-term test-retest reliability of the California Verbal Learning Test - second edition (CVLT-2), a widely used measure of episodic learning and memory...

BACKGROUND: Verbal memory (VM) impairment is prominent in bipolar disorder (BD) and is linked to functional outcomes. However, the intricacies of VM impairment have not yet been studied in a large sample of BD patients. Moreover, some have proposed VM deficits that may be mediated by organizational strategies, such as semantic or serial clustering. Thus, the exact nature of VM break-down in BD patients is not well understood, limiting remediation efforts. We investigated the intricacies of VM deficits in BD patients versus healthy controls (HCs) and examined whether verbal learning differences were mediated by use of clustering strategies...

Word-list learning tasks are among the most important and frequently used tests for declarative memory evaluation. For example, the California Verbal Learning Test-Children's Version (CVLT-C) and Rey Auditory Verbal Learning Test provide important information about different cognitive-neuropsychological processes. However, the impact of test length (i.e., number of words) and semantic organization (i.e., type of words) on children's and adolescents' memory performance remains to be clarified, especially during this developmental stage...

OBJECTIVE: Cognitive impairment is prevalent and related to functional outcome in schizophrenia, but a significant minority of the patient population overlaps with healthy controls on many performance measures, including declarative-verbal-memory tasks. In this study, we assessed the validity, clinical, and functional implications of normal-range (NR), verbal-declarative memory in schizophrenia. METHOD: Performance normality was defined using normative data for 8 basic California Verbal Learning Test (CVLT-II; Delis, Kramer, Kaplan, & Ober, 2000) recall and recognition trials...

Objective: Recall and recognition memory abilities are known to decline with increasing age, yet much of the evidence stems from studies that used simple measures of total target recall or recognition. The California Verbal Learning Test-Second Edition (CVLT-II) includes a new measure of recall discriminability that is analogous to recognition discriminability. These discriminability measures yield more thorough assessments of recall and recognition by accounting for intrusion and false positive errors, respectively...

OBJECTIVE: The identification of a biomarker with prognostic value is an unmet need in multiple sclerosis (MS). The objective of this study was to investigate a possible association of HLA genotype with disease status and progression in MS, based on comprehensive and sensitive clinical and magnetic resonance imaging (MRI) parameters to measure disease effects. METHOD: A total of 118 MS patients (79 females, 39 males) underwent HLA typing. Patient MS status was assessed at two time points in a 2-year interval, based on clinical scores (including EDSS, MSSS, T25FW, 9-HPT, SDMT, BVMT, CVLT-II) and MRI evaluations...
