It accounts for 50% of all dementias in Japan, 20% to 40% in Europe and 15% in Latin America. 25% of people with stroke develop new-onset dementia within one year of their stroke. One study found that in the United States, the prevalence of vascular dementia in all people over the age of 71 is 2.43%, and another found that the prevalence of the ...

Binswanger's disease, also known as subcortical leukoencephalopathy and subcortical arteriosclerotic encephalopathy, [1] is a form of small-vessel vascular dementia caused by damage to the white brain matter. [2] White matter atrophy can be caused by many circumstances including chronic hypertension as well as old age. [3]
The pattern of cognitive impairment in DLB is distinct from other dementias, such as AD; the MMSE mainly tests for the memory and language impairments more commonly seen in those other dementias and may be less suited for assessing cognition in the Lewy body dementias, where testing of visuospatial and executive function is indicated.
