Fitness effects on the cognitive function of older adults: a meta-analytic study.

A meta-analytic study was conducted to examine the hypothesis that aerobic fitness training enhances the cognitive vitality of healthy but sedentary older adults. Eighteen intervention studies published between 1966 and 2001 were entered into the ...

Suppression of contour perception by band-limited noise and its relation to nonclassical receptive field inhibition.

Band-spectrum noise has been shown to suppress the visual perception of printed letters. The suppression exhibits a specific dependence on the spatial frequency of the noise, and the frequency domain of most effective inhibition has been related to the ...

A space-variant filter model of texture segregation: parameter adjustment guided by psychophysical data.

This article presents a space-variant version of a standard spatial filter model of texture segregation of the "back-pocket" type (i.e., two filter layers with an intermediate pointwise nonlinearity). The model was tested with psychophysical data from ...

Familial dementia with Lewy bodies with an atypical clinical presentation.

The authors report a case of a 64-year-old male with Alzheimers disease (AD) and dementia with Lewy bodies (DLB) pathology at autopsy who did not manifest the core symptoms of DLB until very late in his clinical course. His initial presentation of early ...

Effects of cognitive challenge on gait variability in patients with Parkinsons disease.

Attention plays an important role in the gait disturbances of patients with Parkinsons disease (PD); however, the effects of "dual tasking" on fall risk and gait instability have not been well studied. The authors tested the hypothesis that gait ...

Long-term effects of donepezil on P300 auditory event-related potentials in patients with Alzheimers disease.

The P300, one of the cognitive event-related potentials (ERPs) of the cerebral cortex, reflects the functioning of the neurochemical system involved in cognitive processes. We investigated clinical significance of the components of auditory P300 ERPs, in ...

Smoking and cognitive performance in the community elderly: a longitudinal study.

This prospective study investigated the association between smoking and cognitive performance in a community of nondemented elderly subjects aged 65 or older. All subjects were categorized as current smokers, former smokers, or never smokers. The ...

Prospective study of alcohol consumption and risk of dementia in older adults.

CONTEXT: Alcohol consumption has been associated with complex changes in cerebral vasculature and structure in older adults. How alcohol consumption affects the incidence of dementia is less clear. OBJECTIVE: To determine the prospective relationship of ...

Association of ADHD and conduct disorder--brain electrical evidence for the existence of a distinct subtype.

BACKGROUND: To evaluate the impact of psychopathological comorbidity with oppositional defiant/conduct disorder (ODD/CD) on brain electrical correlates in children with attention deficit hyperactivity disorder (ADHD) and to study the pathophysiological ...

The neural basis of individual differences in working memory capacity: an fMRI study.

Using fMRI, neural substrates of verbal working memory were investigated with respect to differences in working memory capacity. Listening-span test (LST), Listen, and Remember conditions were performed. Two subjects groups were selected: those who had ...
