Vascular dementia (VaD) can be defined as a dementia syndrome likely to be the consequence of lesions of the brain, vascular in origin, irrespective of their ischemic, hemorrhagic or hypoxic nature. Six subtypes (1) multi-infarct dementia, (2) strategic single infarct dementia, (3) small-vessel disease with dementia, (4) hypoperfusion dementia, (5) hemorrhagic dementia and other VaD, have been proposed, indicating the broad clinical spectrum of this disorder. Major determinants of the dementia syndrome are (i) stroke characteristics--i.e., lacunar infarcts, localization in the left hemisphere and/or in strategic regions--, (ii) white matter changes frequently seen in stroke patients, especially in those who have lacunes or deep hemorrhages, represent a strong predictor for risk of dementia--and (iii) associated Alzheimer pathology--Alzheimer and vascular lesions are frequently associated. Finally, it should also be considered the role of the summation of various lesion types, since many cases of dementia occurring in stroke patients are multifactorial.

D015140	Dementia, Vascular	An imprecise term referring to dementia associated with CEREBROVASCULAR DISORDERS, including CEREBRAL INFARCTION (single or multiple), and conditions associated with chronic BRAIN ISCHEMIA. Diffuse, cortical, and subcortical subtypes have been described.

D015161	Dementia, Multi-Infarct	Loss of higher cortical functions with retained awareness due to multiple cortical or subcortical CEREBRAL INFARCTION. Memory, judgment, attention span, and impulse control are often impaired, and may be accompanied by PSEUDOBULBAR PALSY; HEMIPARESIS; reflex abnormalities, and other signs of localized neurologic dysfunction.

D020300	Intracranial Hemorrhages	Bleeding within the SKULL, including hemorrhages in the brain and the three membranes of MENINGES. The escape of blood often leads to the formation of HEMATOMA in the cranial epidural, subdural, and subarachnoid spaces.

D020521	Stroke	A group of pathological conditions characterized by sudden, non-convulsive loss of neurological function due to BRAIN ISCHEMIA or INTRACRANIAL HEMORRHAGES. Stroke is classified by the type of tissue NECROSIS, such as the anatomic location, vasculature involved, etiology, age of the affected individual, and hemorrhagic vs. non-hemorrhagic nature.
