Ministrokes may cause dementia, study suggests
Stroke is a leading cause of death and long-term disability in the United States.

Transient ischemic attacks, or "ministrokes," occur when an artery becomes briefly blocked by a blood clot. A ministroke is the same as a regular stroke - the only difference is that they last for a shorter period of time.

Existing research shows that anywhere between 25-30 percent of people who have experienced an ischemic stroke may go on to develop delayed vascular cognitive impairment or vascular dementia.;_c
