Age effects on the neural correlates of successful memory encoding.

Event-related functional MRI (fMRI) was used to investigate the neural correlates of memory encoding as a function of age. While fMRI data were obtained, 14 younger (mean age 21 years) and 14 older subjects (mean age 68 years) made animacy decisions ...

Effects of acute tryptophan depletion on cognitive function in Alzheimers disease and in the healthy elderly.

BACKGROUND: The cholinergic system is profoundly impaired in senile dementia of Alzheimer type (SDAT) and replacement therapy produces only modest clinical benefits. The serotonergic system is also impaired and may contribute both to cognitive and ...

Neural correlates of retrieval processing in the prefrontal cortex during recognition and exclusion tasks.

Event-related fMRI was employed to contrast the neural activity elicited in prefrontal cortex during recognition memory and exclusion tests. The study phases preceding each memory test were identical, involving the presentation of study items (visually ...

Factor structure of a modified version of the wisconsin card sorting test: an analysis of executive deficit in Alzheimers disease and mild cognitive impairment.

In order to explore the factor structure of a modified version of the Wisconsin Card Sorting Test (mWCST) and to identify the dimensions of deficit in patients with Alzheimers disease (AD) and mild cognitive impairment (MCI), conventional mWCST scores in ...

Neurobehavioral functioning of persons with Parkinsons disease.

This study examines the neurobehavioral functioning of persons with Parkinsons disease (PD) using the Neuropsychology Behavior and Affect Profile (NBAP), a self-report version of the Neurobehavioral Rating Scale (NRS-Revised), and the Dysexecutive ...

Tracking cognitive functioning over time: ten-year longitudinal data from a community-based study.

Over 10 years, a community-based sample age 65> or = years, with a starting cohort size of 1,206, was assessed biennially with the Mini-Mental State Exam; the Consortium to Establish a Registry for Alzheimers Disease battery; Immediate and Delayed Recall ...

The effect of education on cognitive performances and its implication for the constitution of the cognitive reserve.

Some studies have suggested that people with a high educational level have a lower risk of developing dementia compared to people with a low educational level. This protective effect of education has been explained by the constitution of a cognitive ...

Frontotemporal dementia: paroxetine as a possible treatment of behavior symptoms. A randomized, controlled, open 14-month study.

Frontotemporal dementia (FTD) represents an important cause for degenerative disruption and is increasingly recognized as an important cause (up to 25%) of degenerative dementia among late-middle-age individuals. The serotoninergic system is tightly ...

Homocysteine: a marker for cognitive performance? A longitudinal follow-up study.

The present prospective study investigated whether elevated total serum homocysteine concentration is a risk factor for cognitive decline. The outcomes were compared to the possible relation between cognition and vitamin B12 or folic acid. Cognitive ...
