#1
REVIEW
Ro J Robotham, Randi Starrfelt
Face and word recognition have traditionally been thought to rely on highly specialised and relatively independent cognitive processes. Some of the strongest evidence for this has come from patients with seemingly category-specific visual perceptual deficits such as pure prosopagnosia, a selective face recognition deficit, and pure alexia, a selective word recognition deficit. Together, the patterns of impaired reading with preserved face recognition and impaired face recognition with preserved reading constitute a double dissociation...

BACKGROUND: There are some existing barriers posed by neuropsychological tests that interfere with the assessment of cognitive functioning by staff who work in long-term care facilities. The purpose of this study was to investigate the feasibility of assessing cognitive function through conversation. METHODS: A total of 100 care staff was randomly selected as participants. Each staff member evaluated cognitive function in one to three residents using the Conversational Assessment of Neurocognitive Dysfunction (CANDy), which is a screening test for dementia using conversation...

OBJECTIVE: Juvenile myoclonic epilepsy (JME) is the most common idiopathic generalized epilepsy syndrome. Neuropsychological, electrophysiological, and neuroimaging studies have led to the hypothesis that JME is related to dysfunction of frontal brain regions and mainly frontal thalamocortical networks. METHODS: We investigated possible microstructural white matter abnormalities of 20 patients with JME as compared with 20 healthy control subjects using diffusion tensor imaging (DTI)...

BACKGROUND: It has been suggested that men and women with Alzheimer's disease (AD) at comparable levels of global cognitive impairment perform differently on neuropsychological measures. Such differences may have practical implications for designing cognitive interventions that address symptoms of dementia. METHODS: We compared men (n = 86) and women (n = 96) with AD on tests of immediate and delayed prose memory, verbal fluency, semantic fluency, semantic memory, and confrontation naming...

OBJECTIVES: Cross-sectional and longitudinal evidence from largely non-Hispanic White cohorts suggests that positive psychosocial factors, particularly self-efficacy and social support, may protect against late-life cognitive decline. Identifying potentially protective factors in racial/ethnic minority elders is of high importance due to their increased risk of Alzheimer's disease. The overall goal of this study was to characterize cross-sectional associations between positive psychosocial factors and cognitive domains among Black, Hispanic, and White older adults...

BACKGROUND: Available treatment options for Parkinson's disease (PD) are primarily aimed at pharmacological and/or neurosurgical management of motor symptoms. However, many patients also experience chronic non-motor symptoms (NMS), including significant cognitive and mood changes. Currently, there is a gap in the neuropsychological literature regarding the efficacy of nonpharmacological treatment options for cognitive and mood changes in PD. OBJECTIVE: We sought to evaluate the efficacy and patient satisfaction of a pilot nonpharmacological intervention for alleviating NMS in patients with PD...

BACKGROUND: The coexistence of depression with mild cognitive impairment (MCI) seems to increase the risk of dementia. However, the explanations of that relationship have been inconsistent. We investigated cognitive profiles in patients with MCI with and without depression and whether changes in depression symptoms affect cognition longitudinally. METHODS: For the study, 161 patients with MCI were divided into a depressed group (D+) and a nondepressed group (D-)...

BACKGROUND: Neuropsychological changes that may occur due to the environmental and psychological stressors of prolonged spaceflight motivated the development of the Cognition Test Battery. The battery was designed to assess multiple domains of neurocognitive functions linked to specific brain systems. Tests included in Cognition have been validated, but not in high-performing samples comparable to astronauts, which is an essential step toward ensuring their usefulness in long-duration space missions...

INTRODUCTION: Drowning is a serious and frequently neglected public health threat. Primary respiratory impairment after submersion often leads to brain dysfunction. Depending on the period of global hypoxia (respiratory failure), clinical aspects of neurological dysfunction are evident on the first evaluation after the water rescue. Nowadays, many neuropsychological assessments after drowning are inconclusive, with some studies reporting only minor neurological or cognitive impairments...

The relationship between statins and cognition in Parkinson's disease (PD) is poorly understood. Analyses were performed to determine associations between statin use and cross-sectional and longitudinal cognitive performance in PD. Neuropsychological tests, medication logs, and ratings of functional abilities were collected from 313 PD participants longitudinally. At baseline, statin users (SU; N = 129) were older, more likely male, and had shorter PD duration than non-statin users (NSU; N = 184). In Cross-sectional analysis, SU performed better on global cognition, Trails B, semantic fluency, and phonemic fluency tasks...

Evaluating performance validity is essential in neuropsychological and forensic assessments. Nonetheless, most psychological assessment tests are unable to detect performance validity and other methods must be used for this purpose. A new Performance Validity Test (DETECTS - Memory Performance Validity Test) was developed with several characteristics that enhance test utility. Moreover, precise response time measurement was added to DETECTS. Two groups of participants (normative and simulator group) completed DETECTS and three memory tests from the Wechsler Memory Scale III...

BACKGROUND AND OBJECTIVES: Data suggest individuals with substance use disorders (SUD) have high rates of attrition from treatment and exhibit impairments on measures of executive functioning (EF). The primary aim of this pilot study was to investigate if EF is associated with attrition from a 1 month intensive outpatient program (IOP) for SUD, and examine the feasibility of implementing the project. METHODS: Baseline neurocognitive functioning was assessed by the Cambridge Neuropsychological Test Automated Battery (CANTAB) and the self-reported Behavior Rating Inventory of Executive Functioning (BRIEF-A) questionnaire...

BACKGROUND: Symptoms of autism spectrum disorder (ASD) and inattention (IA) are highly comorbid and associated with deficits in executive cognition. Cognitive deficits have been posited as candidate endophenotypes of psychiatric traits, but few studies have conceptualized cognitive deficits as psychiatric comorbidities. The latter model is consistent with a latent factor reflecting broader liability to neuropsychological dysfunction, and explains heterogeneity in the cognitive profile of individuals with ASD and IA...
