Abstract Objective To study the subtypes and developing features of post-hemorrhagic stroke dementia.Methods Eligible cases were collected by following-up and neuropsychological tests,and their subtypes were divided into possible AD and VaD in terms of NINCDS-ADRDA and NINDS-AIREN respectively. The incidence time between the two subtypes, as well as between the operation group and non-operation group were then analyzed.Results According to the Kaplan-meier analysis,the mean incidence time of possible AD was (17.19±2.20) months,95%CI(12.89~21.50); and that of possible VaD was (27.53±2.09)months,95%CI(23.43~31.62).The difference between the two subtypes was significant(χ2=6.71,P<0.05).Conclusions The presentation of post-hemorrhagic stroke dementia varies in terms of neuropsychological test significantly shifting from possible AD-type to VaD-type. The average developmental time of AD-type is earlier than that of VaD-type. Operation doesn't affect the development of post-hemorrhagic stroke dementia.

1.2 方法 脑中风后痴呆的诊断依据的是国际疾病分类标准(第十次修订版)[3]。痴呆按神经心理学表现分亚型为可疑AD型和VaD型,分别依据的是美国国立神经病学、语言障碍和卒中研究所-阿尔茨海默病及相关疾病协会(national institute of neurological and communicative disorders and stroke; alzheimer's disease and related disorders association,NINCDS-ADRDA)标准[4]和美国国立神经病及卒中研究所-瑞士神经科学国际研究会(national institute of neurological disorders and stroke,association inter-nationale pourla rechercheetl Enseignement enneuro-sciences,NINDS-AIREN)标准[5]。记录两亚型发展为痴呆的时间,比较手术组和非手术组可疑AD型和VaD型PSD病程发展的差别,并绘制了两者的生存分析曲线。
