What is cerebrovascular dementia?
Dementia is currently divided into four types: senile dementia, vascular dementia, mixed dementia and other dementias.
銆€銆€Cerebrovascular dementia refers to dementia caused by brain function of cerebrovascular disease.
Some reports say that the disease can account for 8-39% of all dementia, while in Japan it is often reported that cerebrovascular dementia is about 60%, it is also reported to be about 60%.
It can be seen that cerebrovascular disease causes dementia.
銆€銆€Cerebrovascular dementia is mainly caused by cerebral arteriosclerosis, multiple lacunar infarction or a single large-area cerebral infarction, and the more small infarcts, the less chance of dementia.
However, a moderately cerebral infarction or cerebral hemorrhage can sometimes cause dementia, especially when it occurs in the brain where it is closely related to the occurrence of dementia.
Therefore, the occurrence of cerebrovascular dementia is closely related to the size, location and location of cerebral infarction.
銆€銆€The general symptoms of cerebrovascular dementia are insomnia, nighttime snoring, worry, depression and emotional changes, strong crying or strong laughter, or accompanied by hallucinations, delusions, behavioral personality changes, unclean behavior, language disadvantages or mistakes, and memory impairment, smart low and so on.
銆€銆€The disease often has high blood pressure, a history of arteriosclerosis, and the condition progresses stepwise, that is, some brain function is missing in the early stage, while other brain functions still exist, such as memory impairment, but the judgment and understanding are still normal.
A small number of patients have insidious onset, progress slowly, and have no history of repeated strokes.
銆€銆€Regarding the diagnosis of the disease, the criteria set by the American Psychiatric Association in 1979 are: 1 Dementia patients with low consciousness, poor mental performance, memory loss, and at least some of the following abnormalities: abstract thinking, judgment, language, behavior andPersonality changes.
銆€銆€2 The course of disease progressed step by step, and early reports of “spot-like dementia” (ie, partial function loss, while other functions still exist).
銆€銆€3 focal neurological symptoms such as single limb weakness, pathological signs positive, deep reflex force or gait abnormalities.
銆€銆€4 From the medical history, physical examination or laboratory examination, there is evidence of obvious cerebrovascular disease, and it is considered to be the cause of the disease.
