A stroke also can happen when a blood vessel in the brain bursts. The main causes of strokes are untreated high blood pressure, high blood cholesterol, diabetes, and heart disease. Of these, the most important risk factor for multi-infarct dementia is high blood pressure. It is rare for a person without high blood pressure to develop multi-infarct dementia. Currently there is no treatment for MID that can reverse the damage that has already occurred.
Treatment focuses on prevention of additional brain damage by controlling high blood pressure.
Treatment is based on control of symptoms.
