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).
Yet again, in 1974 the term multi-infarct dementia was coined and all vascular dementia was grouped into one category. Because of this, the specific names of these types of this dementia, including Binswanger's disease were lost. [4]
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]
Dementia with Lewy bodies (DLB) is a type of dementia, a group of diseases involving progressive neurodegeneration of the central nervous system. [11] It is one of the two Lewy body dementias, along with Parkinson's disease dementia. [12] Dementia with Lewy bodies can be classified in other ways.
Red softening is one of the three types of cerebral softening. As its name suggests, certain regions of cerebral softening result in a red color. This is due to a hemorrhagic infarct, in which blood flow is restored to an area of the brain that was previously restricted by an embolism. This is termed a "red infarct" or also known as red ...
The normal life expectancy for 60 to 70 years old is 23 to 15 years; for 90 years old it is 4.5 years. [219] Following AD diagnosis it ranges from 7 to 10 years for those in their 60s and early 70s (a loss of 13 to 8 years), to only about 3 years or less (a loss of 1.5 years) for those in their 90s.
Older adults who have experienced a traumatic injury after a fall are 21 percent more likely to later receive a diagnosis of Alzheimer’s disease or another related dementia, a new study indicates.
CADASIL or CADASIL syndrome, involving cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy, is the most common form of hereditary stroke disorder, and is thought to be caused by mutations of the NOTCH3 gene on chromosome 19. [1]
