Evidence suggests that physical activity (PA) is associated with the maintenance of cognitive function across the lifespan. In contrast, the apolipoproteinE-ε4 (APOE-ε4) allele, a genetic risk factor for Alzheimer's disease (AD), is associated with impaired cognitive function. The objective of this study was to examine the interactive effects of PA and(More)
The effect of physical activity (PA) on functional brain activation for semantic memory in amnestic mild cognitive impairment (aMCI) was examined using event-related functional magnetic resonance imaging during fame discrimination. Significantly greater semantic memory activation occurred in the left caudate of High- versus Low-PA patients, (P=0.03),(More)
OBJECTIVE Assessment of emotional functioning is important in sport-related concussion (SRC) management, although few standardized measures have been validated in this population, and appropriate normative data are lacking. We investigated the psychometric properties of the Brief Symptom Inventory-18 (BSI-18) in high school and collegiate athletes at risk(More)
Older adult apolipoprotein-E epsilon 4 (APOE-ε4) allele carriers vary considerably in the expression of clinical symptoms of Alzheimer's disease (AD), suggesting that lifestyle or other factors may offer protection from AD-related neurodegeneration. We recently reported that physically active APOE-ε4 allele carriers exhibit a stable cognitive trajectory and(More)
— The generative model of computer vision, along with local features represented by quantized Scale Invariant Feature Transform (SIFT) descriptors, are used to classify writers based on images taken of Arabic text documents. It is the first known application of the method to automated writer recognition. This statistically based approach does not exploit(More)
