Multi-infarct dementia (MID) is a common cause of memory loss in the elderly mainly affects elderly people with arteriosclerosis (hardening of the arteries). An individual having a silent stroke may not even know it is happening, but over time, as more areas of the brain are damaged and more small blood vessels are blocked, the symptoms of MID begin to appear. They may be caused by poor diet, lack of sleep, or too many medicines, for example. Feelings of loneliness, boredom, or depression also can cause forgetfulness The term refers to a group of syndromes caused by different mechanisms all resulting in vascular lesions in the brain. The term dementia describes a medical condition that is caused by changes in the normal activity of very sensitive brain cells.
These changes in the way the brain works can affect memory, speech, and the ability to carry out daily activities. Vascular lesions can be the result of diffuse cerebrovascular disease or focal lesions (or a combination of both, which is what is observed in the majority of cases). Since the diseases often occur together, making a single diagnosis of one or the other is even more problematic.
Multi Infarct Dementia Causes
Multi-infarct dementia is a form of dementia caused by large numbers of small blood clots (emboli) in the brain that starve the brain cells of oxygen. Dementia is caused by degeneration in the cerebral cortex including death of brain cells, conditions that impair the vascular or neurologic structures of the brain. Multi-infarct dementia is not caused directly by the deposits of atherosclerotic plaque in the blood vessels of the brain, but by a series of strokes that leave areas of dead brain cells (infarction). This occurs when atherosclerotic plaques facilitate the formation of blood clots (thrombi) that block off the small blood vessels and prevent localized areas of the brain from receiving nutrients and oxygen from the blood flow that supplies them.
Multi Infarct Dementia Symptoms

Multi Infarct Dementia treatment
Multi Infarct Dementia can be treatment. If you have cardiac irregularities as well, powerful anticoagulants are necessary such as warfarin or phenindione. The dementia itself is untreatable and the patient may eventually need constant care. The person should be in a pleasant, comfortable, non-threatening, physically safe environment for diagnosis and initial treatment. Hospitalization may be required for a short time. The underlying causes should be identified and treated as appropriate. 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. Every condition known to increase the risk of arteriosclerosis or blood clots also increases the risk of multi-infarct dementia. These are:
