Multi-infarct dementia results from a series of small strokes affecting several brain regions. Stroke-related dementia involving successive small strokes causes a more gradual decline in cognition. [4] Dementia may occur when neurodegenerative and cerebrovascular pathologies are mixed, as in susceptible elderly people (75 years and older).
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]

Anything that affects brain function (including stroke or other conditions that compromise blood flow) can cause cognitive issues and even dementia. Vascular dementia can happen after a stroke ...
The vocabulary of diseases associated with Lewy pathology causes confusion. [15] Lewy body dementia (the umbrella term that encompasses the clinical diagnoses of dementia with Lewy bodies and Parkinson's disease dementia) differs from Lewy body disease (the term used to describe pathological findings of Lewy bodies on autopsy). [15]
More than one type of dementia, known as mixed dementia, may exist together in about 10% of dementia cases. [2] The most common type of mixed dementia is Alzheimer's disease and vascular dementia. [87] This particular type of mixed dementia's main onsets are a mixture of old age, high blood pressure, and damage to blood vessels in the brain. [15]
Heart problems can increase dementia risk, but a new study suggests that heparin, a common anticoagulant administered via injection, may help delay Alzheimer’s onset.
The fifth revision of the Diagnostic and Statistical Manual of Mental Disorders gives Lewy body disease as the causative subtype of dementia with Lewy bodies, and Parkinson's disease as the causative subtype of Parkinson's disease dementia. [10] Dementia with Lewy bodies is marked by the presence of Lewy bodies primarily in the cortical regions ...
