The type of vascular dementia and symptoms of
Dementia caused by cerebrovascular disease called vascular dementia. Cerebrovascular diseases including cerebral infarction, cerebral hemorrhage, subarachnoid hemorrhage. Cerebrovascular disease is the most common cause of atherosclerosis, there are rare blood disease, collagen disease, vascular malformations. Common clinical vascular dementia types are:

    (1) Multi-infarct dementia: the most common type. Is due to lesions caused by multiple infarct dementia and other disorders can affect the cerebral cortex, subcortical and basal ganglia. Often clinical hypertension, arteriosclerosis, recurrent brain disease, and each left more or less after onset of neurological and mental symptoms, add up and eventually become a comprehensive, serious mental decline.

    (2) a large area infarct dementia: a large area in patients with cerebral infarction, and often died in the acute phase, a small number of patients remaining alive in varying degrees of neuropsychiatric abnormalities, including dementia, loss of work and life skills.
    (3), subcortical arteriosclerotic encephalopathy (Binswager disease): a result of arteriosclerosis, diffuse white matter lesions occur, but there dementia. Clinical features of smart decreased, gait disorder, urinary incontinence, difficulty swallowing, drinking water, choking, slurred speech and so on.

    (4) special parts of infarct induced dementia: is infarct though not large, but located in an important bearing on cognitive function parts, which leads to aphasia, memory impairment, visual barriers. 

    (5), hemorrhagic dementia: chronic subdural hematoma, subarachnoid hemorrhage, cerebral hemorrhage can produce vascular dementia

Dementia patients have a history of cerebrovascular disease, such as the onset of stroke or transient ischemic attack history, there are limitations of the nervous system symptoms or signs, confirmed damage to the nervous system, coupled with now more popular CT or MRI examination of the positive results, in line with for the limitations of early dementia, advanced dementia progressed to a comprehensive mental retardation, as well as the volatility characteristics of course and so on, diagnosis of vascular dementia is not difficult, difficult is early detection.

For early detection, it should be right where hypertension, cerebral arteriosclerosis, cerebrovascular disease patients, for memory and intelligence were investigated for early detection, early treatment, the sooner the better.
