Poststroke Dementia among Older Adults
Stroke and dementia are major health problems affecting older people. Cerebrovascular disease is the second-leading cause of dementia after Alzheimer’s disease, the third- leading cause of death, and one of 10 leading causes of physical disability. In parallel with the increased prevalence of stroke in aging populations and the decline in mortality from stroke, the rate of diagnosed poststroke dementia has increased, causing a growing financial burden for health care systems. This article discusses the epidemiology, etiology, and determinants of poststroke dementia and outlines the search for a suitable treatment.
