Objectives: To investigate maintenance of training effects of a novel brain plasticity-based computerized cognitive training program in older adults after a 3-month no-contact period.; Design: Multisite, randomized, controlled, double-blind trial with two treatment groups.; Setting: Communities in northern and southern California and Minnesota.; Participants: Four hundred eighty-seven community-dwelling adults aged 65 and older without diagnosis […]
Comparing registration methods for mapping brain change using tensor-based morphometry
Measures of brain changes can be computed from sequential MRI scans, providing valuable information on disease progression for neuroscientific studies and clinical trials. Tensor-based morphometry (TBM) creates maps of these brain changes, visualizing the 3D profile and rates of tissue growth or atrophy. In this paper, we examine the power of different nonrigid registration models […]
Memantine effects on verbal memory in fragile X-associated tremor/ataxia syndrome (FXTAS): A double-blind brain potential study

Older FMR1 premutation carriers may develop fragile X-associated tremor/ataxia syndrome (FXTAS), a neurodegenerative disorder manifesting cognitive deficits that often subsequently progress to dementia. To date, there is no specific treatment available for FXTAS. Studies have demonstrated the premutation-associated overactivation of glutamatergic receptors in neurons. Memantine, a NMDA receptor antagonist approved for treatment of Alzheimer’s disease, […]
Detecting frontotemporal dysfunction in ALS: utility of the ALS Cognitive Behavioral Screen (ALS-CBS)

Schulz, Paul E.,
Katz, Jonathan S.
Up to half of patients with ALS develop cognitive impairment during the course of the illness. Despite this, there is no simple tool for screening patients in the clinical setting. This study examines the sensitivity, specificity and accuracy of the ALS Cognitive Behavioral Screen (ALS-CBS). We administered the measure to 112 ALS patients, including 31 […]
Walking stabilizes cognitive functioning in Alzheimer’s disease (AD) across one year

Mungas, D.,
Chui, H.,

Hewett, L.,
Cotman, C.W.
AD is a public health epidemic, which seriously impacts cognition, mood and daily activities; however, one type of activity, exercise, has been shown to alter these states. Accordingly, we sought to investigate the relationship between exercise and mood, in early-stage AD patients (N=104) from California, over a 1-year period. Patients completed the Mini-Mental State Examination […]

Importance: Persons with type 2 diabetes mellitus (T2DM) are at increased risk for decline in cognitive function, reduced brain volume, and increased white matter lesions in the brain. Poor control of blood pressure (BP) and lipid levels are risk factors for T2DM-related cognitive decline, but the effect of intensive treatment on brain function and structure […]
Video-based coping skills to reduce health risk and improve psychological and physical well-being in Alzheimer’s disease family caregivers

Vendittelli, Analise P.,
Hutchins, Tiffany C.,
Williams, Redford B.
Objective: To determine whether video-based coping skills (VCS) training with telephone coaching reduces psychosocial and biological markers of distress in primary caregivers of a relative with Alzheimer’s disease or related dementia (ADRD).; Methods: A controlled clinical trial was conducted with 116 ADRD caregivers who were assigned, alternately as they qualified for the study, to a […]

Objective: To determine the long-term tolerability and efficacy of donepezil in patients with vascular dementia (VaD).; Methods: International, multicentre, open-label, 30-week extension study of two 24-week, randomised, double-blind, placebo-controlled studies. Participants were ambulatory adults (59% female; mean age, 74.7 +/- 0.3) with a diagnosis of possible or probable VaD and without a diagnosis of Alzheimer’s […]
