Aphasia, depression, and non-verbal cognitive impairment in ischaemic stroke.

Aphasia, depression, and cognitive dysfunction are common consequences of stroke, but knowledge of their interrelationship is limited. This 1-year prospective study was designed to evaluate prevalence and course of post-stroke aphasia and to study its psychiatric, neurological, and cognitive correlates. We studied a series of 106 consecutive patients (46 women and 60 men, mean age 65.

Auditory P300 event related potential in minor ischemic stroke.

Objective: Various degenerative cerebral diseases and even depression may cause abnormalities of the cognitive event related potentials (ERPs). We conducted the present study to elucidate the effects of ischemic stroke on the P300 ERP component.

Material And Methods: We recorded the P300 wave using an auditory oddball paradigm in 38 consecutive brain infarct patients with mild neurological deficits at 3 and 12 months post-stroke, and in 29 healthy control subjects.

Poststroke depression correlates with cognitive impairment and neurological deficits.

Background And Purpose: The prevalence of poststroke depression is known to be high, but the knowledge of its neuropsychological correlates is limited. This 12-month prospective study was designed to evaluate the natural history of poststroke depression and to study its neuropsychological, clinical, and functional associates.

Methods: We studied a series of 106 consecutive patients (46 women and 60 men, mean age 65.
