Single cerebral infarct dementia

Large-scale infarction of the brain tissue and single infarction of some important brain functional parts may show clinical manifestations of dementia. Large-area cerebral infarcts with a volume of more than 50 to 60 ml can cause most of the functions of one side of the frontal or temporal lobe or even the cerebral hemisphere to be damaged, and localized signs and dementia can occur. Dementia is related to the location of the lesion, and the thalamus, horn gyrus, frontal base, and limbic system are closely related to dementia. Bilateral thalamus and bottom thalamic lesions can form thalamic dementia, which is rare in clinical practice.
