Cognitive deficits may significantly worsen the quality of life after stroke.Our aim was to determine the frequency of dementia in a consecutive series of previously nondemented patients between the ages of 40 and 79 years at 3 months after a first ischemic stroke.Dementia is relatively frequent after a clinical first stroke in persons younger than 80 years, and aphasia is very often associated with poststroke dementia.If aphasic patients are not considered,it may be necessary to screen a very large number of subjects to collect an adequate sample of demented cases. |
