HIF-1α is a hypoxia-inducible protein that regulates many cell and molecular processes, including those involved in angiogenesis and stem cell maintenance. Prior studies demonstrated constitutive HIF-1α stabilization in neural stem cells (NSCs) of the adult mouse SVZ, but its role there has not been elucidated. Here, we tested the hypothesis that HIF-1α(More)
Gestational alcohol exposure leads to a spectrum of neurological symptoms which range from severe mental retardation caused by high dose exposure, to subtle cognitive and neuropsychiatric symptoms caused by low-to-moderate doses. We and other investigators have demonstrated that exposure to moderate levels of alcohol throughout gestation leads to impaired(More)
OBJECTIVE The overall goal of our current study was to examine older adults' experience of Flow (i.e., subjective engagement) during the course of a home-based cognitive training program. MATERIALS AND METHODS In this study, participants took part in a home-based training program. They were randomized to one of the two training groups. One group played an(More)
Rates of mild cognitive impairment (MCI) have varied substantially, depending on the criteria used and the samples surveyed. The present investigation used a psychometric algorithm for identifying MCI and its stability to determine if low cognitive functioning was related to poorer longitudinal outcomes. The Advanced Cognitive Training of Independent and(More)
Objective: This study explored whether age moderated cognitive, symptom, and functional changes over a 12-week compensatory cognitive training (CCT) intervention for participants with severe mental illnesses. CCT focused on the cognitive domains of attention, learning, prospective memory, and executive functioning, often impaired in this population. Method:(More)
Exercise "stress tests" are widely used to assess cardiovascular function and to detect abnormalities. In line with the view of exercise as a stressor, the present study examined the relationship between cognitive function and cardiovascular activity before and after light physical exercise in a sample of 84 non-demented community-dwelling older adults.(More)
The objective of this study was to examine whether cognitive change and age predicted work outcome in the context of supported employment (SE) and compensatory cognitive training (CCT) in severe mental illness. Forty unemployed outpatients receiving SE (7 young [20-35 years], 15 middle-aged [36-50 years], and 18 older [51-66 years] patients) completed(More)
We investigated how race and verbal prompting interacted with age to predict age trajectories on a performance-based measure of everyday cognition. African American (n = 727) and White (n = 2052) older adults from the ACTIVE clinical trial were given the Observed Tasks of Daily Living (OTDL; a performance-based measure of medication(More)
OBJECTIVE This study investigated the effect of verbal prompting on elders' 10-year longitudinal change in everyday cognition. Differential effects of prompting associated with impaired cognitive status were also examined. METHOD At baseline, 2,802 participants (mean age = 73.6 years, mean education = 13.5 years) from the Advanced Cognitive Training for(More)
