Multi-infarct dementia (MID)

A form of dementia, also known as vascular dementia, caused by a number of strokes in the brain. These strokes can affect some intellectual abilities, impair motor and walking skills, and cause an individual to experience hallucinations, delusions or depression. The onset of MID usually is abrupt and often progresses in a stepwise fashion. Individuals with MID are likely to have risk factors for strokes, such as high blood pressure, heart disease or diabetes. MID cannot be treated; once nerve cells die, they cannot be replaced. However, risk factors can be treated, which may help prevent further damage.
