A Clinical Study on Cerebral Dysfunction in the Elderly Diabetic Patients with Cerebral Infarction

Objective:To explore the character of the cerebral function, intelligence and memory in the elderly type 2 diabetes mellitus patients with cerebral infarction. Methods:With testing of Halstead Reitan Battery Revised in China〔HRB(A)-RC〕, Wechsler Adult Intelligence Scale Revised in China(WAIS-RC)and Wechsler Memory Scale Revised in China(WMS-RC), we measured the cerebral function in 45 elderly type 2 diabetes mellitus patients with cerebral infarction and 60 cerebral infarction patients without diabetes mellitus and 45 normal subjects without cerebral infarction served as control. We also analysed the effect of the infarction size, numbers and region on cerebral function damage. Results:The scores of the elderly type 2 diabetes mellitus patients with cerebral infarction in most part were significantly lower than that of the cerebral infarction patient without diabetes mellitus and the controls; The patients who have large cerebral infarction size and are subcortex infarction were liable to induce cerebral dysfunction than the small and the cortex infarction(P0.05),especially in basal nuclei, paraventricular and thalamus. There is no significant difference between the more and the one cerebral infarction size(P0.05). Conclusion:The elderly type 2 diabetes mellitus patients with cerebral infarction could induce more obvious cerebral dysfunction.
