In addition, the doctor may send the patient to a psychologist or psychiatrist to test reasoning, learning ability, memory, and attention span. Sometimes, multi-infarct dementia is difficult to distinguish from Alzheimer's disease. It is possible for a person to have both multi-infarct dementia and Alzheimer's disease, making it hard for the doctor to diagnose either. While no treatment can reverse damage that has already been done, treatment to prevent additional strokes is very important. High blood pressure, the primary risk factor for multi-infarct dementia, can be treated successfully.
Diabetes also is a treatable risk for stroke.
To prevent additional strokes, doctors may prescribe medicines to control high blood pressure, high cholesterol, heart disease, and diabetes. They will counsel patients about good health habits, such as exercising and avoiding smoking and drinking alcohol. The patient may require a special diet. Doctors sometimes prescribe aspirin or other drugs to prevent clots from forming in the small blood vessels. Drugs also can be prescribed to relieve restlessness or depression or to help the patient sleep better.
