Multi-infarct dementia (MID)

Question

Quizplus · Accepted Answer

Multi-infarct dementia (MID) is caused by problems with blood flow to the brain, specifically through repeated small strokes or a major stroke. This can result in damage to the brain tissue and cognitive decline. It is considered a type of vascular dementia, which is the second most common cause of dementia after Alzheimer's. While the progression of MID can vary, it is considered irreversible. There is no evidence to suggest that it is caused by a virus. Some studies suggest that the cerebral cortex may be affected more severely in MID than in Alzheimer's, although this can also vary depending on the individual case.
