Long-Term Risk of Dementia Among Survivors of Ischemic or Hemorrhagic Stroke.

ABSTRACT:

Background and purpose

Stroke is a risk factor for dementia, but the risk of dementia after different stroke types is poorly understood. We examined the long-term risk of dementia among survivors of any first-time stroke and of first-time ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage.
