血管性痴呆与脑梗塞部位及促发因素相关性探讨

本文报道24例血管性痴呆(其中基底节6例、丘脑7例、内囊6例、左皮层大面积及皮质下基底节4例,左侧额叶1例)。多发性梗塞灶19例,单发性梗塞灶5例,梗塞灶少者1个,多者8个,平均为4个梗塞灶。1年内复发者12例,2～3年复发10例,5年以上复发2例,其中2次以上发病占90%。所有血管性痴呆全部有脑萎缩,且呈中央性萎缩。并就脑梗塞部位,反复发作性及多灶性梗塞、脑萎缩等成因相互关系进行探讨。

The relationship between cerebrovascular dementia & the location and some ontributing factors of cerebro infarction

24 Patients with Vascular dementia were investigated in the present study, which included 19 cases with Multiinfarct foci and 5 cases with mono-infarct focus. The number of infarct focus was from 1 to 8, and 4 foci in average. Among the patients, 12 relapsed within 1 year, 10 within 2-3 years and 2 after more than 5 years. The cases with two times or more of recurrence were 90%. All the patients with vascular dementia showed central brain atrophy. Such factors as the location recurrence and multiplle foci of brain infarction as well as brain atrophy and their relationship to dementia were discussed.
