The current study sought to investigate the factor structure of the California Verbal Learning Test-Second Edition (CVLT-II) Short Form in a trauma-exposed sample. We used confirmatory factor analysis to test four competing models proposed by Donders in a study investigating the CVLT-II Standard Form. Consistent with Donders, a four-factor model consisting of Attention Span, Learning Efficiency, Delayed Memory, and Inaccurate Memory was supported. These results confirm the latent structure of the CVLT-II holds for the CVLT-II in its Short Form as well as in a trauma-exposed sample. Findings are particularly important, given previous research indicating attention span and learning efficiency may underpin memory complaints in trauma-exposed individuals.

Background: Mild cognitive function (MCI) is associated with a declined short-term memory (STM). This study compared STM between adults with MCI and normal cognition assessed by verbal memory vs visuospatial memory.
Methods: Sixteen subjects with MCI and 11 subjects with normal cognition gave their written consent to participate in the study which was approved by the North Texas Regional IRB.

Department of Psychiatry, University of California, San Diego, San Diego, CA, USA.
Background: Alzheimer's disease (AD) pathology (e.g., beta-amyloid plaques, tau neurofibrillary tangles) accumulates before the emergence of cognitive deficits that lead to a diagnosis of mild cognitive impairment (MCI) or dementia.

Background And Objectives: Moderate-to-severe traumatic brain injuries (TBI) have been reported to increase the risk of Alzheimer disease (AD). Whether mild TBI (mTBI) in veterans confers a similar increased risk of AD is less known. This study investigated early AD changes using CSF biomarkers in veterans with blast mTBI.

This study tested the hypothesis that healthy aging attenuates cognitive practice effects and, consequently, limits the familiarity-associated reductions in heart rate (HR) and breathing frequency (BF) responses during retesting. : Twenty-one cognitively normal older and younger adults (65 ± 2 vs. 26 ± 1 years old) participated in the study.

Background: Sleep disorders are common in people with multiple sclerosis (PwMS) and could contribute to cognitive dysfunction. However, effects of pathological sleep on cognitive domains are insufficiently characterized.
Objective: To evaluate associations between cognitive performance and polysomnographic (PSG)-based sleep disturbances in PwMS.
