Abstract:
Objective\ To explore the risk factors of dementia induced by stroke.Methods\ 258 elder patients with stroke had been followed up for three months,including clinical neuropathy and neuropsychological tests.Multivariate noncondition stepwise Logistic model analysis was made after single variable analysis.Results\ There were 83 patients with dementia induced by stroke,175 patients without dementia after stroke.The morbidity was 32.2%.The following eight factors were associated with dementia i.e.,age,multiple lesions,left lesion,large area of cerebral hemorrhage or cerebral infarction,cerebral atrophy,hypertension,the history of stroke,and bilateral lesions.Conclusions\ Dementia induced by stroke is caused by multiple factors.It is closely correlated to numbers of cerebral lesions,the location of cerebral lesions and the size of brain tissue necrosis.The primary conditions of patients'cerebral function are also closely associated with the occurence of dementia.
