Vascular dementia

Vascular dementia is characterized by a chronic progressive multifaceted impairment of cognitive function.

Loss of brain parenchyma is predominantly from cerebrovascular causes such as infarction and small-vessel changes.

Vascular dementia is the second most common cause of dementia in older people after Alzheimer disease.

A large overlap exists between vascular and Alzheimer disease and many patients have a mixed form of dementia.

Early aggressive treatment of vascular risk factors is suggested in order to prevent further cerebrovascular disease. Supportive care and management of behavioral and psychological symptoms are also important. Treatments aimed at improving cognitive symptoms have shown no clear benefit.

Vascular dementia is a chronic progressive disease of the brain bringing about cognitive impairment. The executive functions of the brain such as planning are more prominently affected than memory. Motor and mood changes are often seen early. The underlying damage occurs to both gray matter and white matter from predominantly vascular causes: that is, infarction, leukoaraiosis, hemorrhage, and small-vessel changes. Mixed dementia (vascular dementia with comorbid Alzheimer disease) is common.
