Motor impairment in normal aging, clinically possible Parkinsons disease, and clinically probable Parkinsons disease: longitudinal evaluation of a cohort of prospective brain donors.

This study presents data on the antemortem evaluations of a cohort of individuals registered in a brain donation program. Clinical evaluation determined that many individuals were unaware they had clinical signs of Parkinsons disease (PD) (rest tremor, ...

Individual differences in working memory within a nomological network of cognitive and perceptual speed abilities.

It has become fashionable to equate constructs of working memory (WM) and general intelligence (g). Few investigations have provided direct evidence that WM and g measures yield similar ordering of individuals. Correlational investigations have yielded ...

The role of medial temporal lobe structures in implicit learning: an event-related FMRI study.

The medial temporal lobe (MTL) has been associated with declarative learning of flexible relational rules and the basal ganglia with implicit learning of stimulus-response mappings. It remains an open question of whether MTL or basal ganglia are involved ...

Cognitive activity and incident AD in a population-based sample of older persons.

BACKGROUND: Participation in cognitively stimulating activities is hypothesized to be associated with risk of AD, but knowledge about this association is limited. METHODS: A biracial community in Chicago was censused, persons aged 65 years and older were ...

Cognitive procedural learning in patients with fronto-striatal lesions.

Previous studies on the role of prefronto-striatal loop systems for cognitive procedural learning (PL) brought inconsistent results. To examine whether the integrity of the dorsolateral prefrontal loop is indispensable for normal cognitive PL, we ...
