, also called subcortical vascular dementia, is a type of dementia caused by widespread, microscopic areas of damage to the deep layers of white matter in the brain. Most patients experience progressive memory loss and deterioration of intellectual abilities (dementia), urinary urgency or incontinence, and an abnormally slow, shuffling, unsteady pattern of walking, usually over a 5-10 year period. While there is no cure, the progression of Binswanger's disease can be slowed with healthy lifestyle choices. Treatment is symptomatic and supportive.
