Depression in Older Adults 12 Months After Traumatic Brain Injury: A TRACK-TBI Study.

Objective: To investigate depression at 12 months after traumatic brain injury (TBI) in older adults compared with younger adults.

Design: Prospective longitudinal cohort study of persons with medically documented mild, moderate, and severe TBI at 12 months postinjury.

Setting: Eighteen participating Level 1 trauma centers in the United States.

The relationship of cognitive change over time to the self-reported Ascertain Dementia 8-item Questionnaire in a general population.

Objective: The aim of the study was to examine the relationship between longitudinally assessed cognitive functioning and self-reported dementia status using the Ascertain Dementia 8-item questionnaire (AD8) in a national population-based sample.

Methods: The analysis included 14,453 participants from the REasons for Geographic and Racial Differences in Stroke study. A validated cutoff of ≥2 symptoms endorsed on the AD8 (administered 10 years after enrollment) represented positive AD8 status.

The relationship of longitudinal cognitive change to self-reported IADL in a general population.

This study examined the relationship between cognitive change and instrumental activities of daily living (IADL) in a large, national, population-based sample. Cognitive change was assessed via verbal fluency, word list learning (WLL), and word list delayed recall (WLD). Incident cognitive impairment was defined by change in Six-Item Screener (SIS) status over a period of 10 years.

Utilization of the Patient Competency Rating Scale in an epileptic and non-epileptic veteran population.

Differentiating between epilepsy and psychogenic non-epileptic events (PNEE) can be difficult given similar presentations. PNEE is often misdiagnosed, resulting in unwarranted treatment with anti-epileptic drugs (AED). While the gold standard for differentiating PNEE from epilepsy is video EEG (VEGG) monitoring, self-reported symptomology has also been shown to discriminate between epilepsy and PNEE with high accuracy, particularly in cases where VEEG is difficult to obtain or when there are no observed events during extended monitoring.

Olfactory ability in normal pressure hydrocephalus as compared to Alzheimer's disease and healthy controls.

Objectives: Normal pressure hydrocephalus (NPH) is a treatable neurological disorder that appears in older adults, lacks specific diagnostic criteria, and resembles symptoms seen in Alzheimer's disease (AD). Presently, differentiating NPH from AD in the early stages of symptom presentation remains difficult. This study established whether olfactory testing may be useful in this regard.

Stroke Symptoms With Absence of Recognized Stroke Are Associated With Cognitive Impairment and Depressive Symptoms in Older Adults With Diabetes.

Self-reported stroke symptoms may represent unrecognized cerebrovascular events leading to poorer cognitive and mental health. We examined relationships between stroke symptoms, cognitive impairment, and depressive symptoms in a high-risk sample: 247 adults aged ≥65 with diabetes. Stroke symptoms were assessed using the Questionnaire for Verifying Stroke-free Status, cognitive impairment was measured with the modified Telephone Interview for Cognitive Status, and depressive symptoms were measured using the 15-item Geriatric Depression Scale.

Social anxiety and social cognition: the influence of sex.

Current theoretical models predict a negative relationship between social anxiety and performance on measures of social cognition, yet there appears to be relatively little research that directly examines this relationship and the potential interaction of sex. Two samples of undergraduates self-reporting either a high (n=27; 59% female) or low (n=29; 62% female) level of social anxiety on the abbreviated Social Phobia and Anxiety Inventory completed two social cognition measures: the Reading the Mind in the Eyes Test (Eyes Test) and The Awareness of Social Inference Test-Parts 2 and 3). A multivariate analysis of variance revealed a significant group by sex interaction on overall social cognition performance.
