Causes
By Mayo Clinic staffVascular dementia is most often caused by either a:
- Complete blockage of blood vessels in the brain. The complete blockage of an artery in the brain usually causes a stroke (infarction), but some blockages don't produce stroke symptoms. These "silent brain infarctions" increase a person's risk of vascular dementia. The risk increases with the number of infarctions experienced over time. One variety of vascular dementia is called multi-infarct dementia. Heart disease and irregular heart rhythms, such as atrial fibrillation, can increase your risk of stroke.
- Narrowing of the blood vessels in the brain. Vascular dementia also can occur without a complete blockage of an artery. Portions of the brain can be starved for oxygen and food by reduced blood flow from arteries narrowed by vascular disease.
Vascular dementia can also be caused by:
- Profoundly low blood pressure
- Brain damage caused by brain hemorrhage
- Blood vessel damage from such disorders as lupus erythematosus or temporal arteritis
