动脉瘤性蛛网膜下腔出血后认知功能检查及损害特点

目的：检测动脉瘤性蛛网膜下腔出血后认知功能损害的发生率及损害程度。分析SAH对认知功能的影响。方法：对37例动脉瘤性蛛网膜下腔出血病人手术前进行了认知功能检查。检查内容包括算术、数字广度、数字符号、图画填充、视觉再生、词语流畅性测验、连线测验、简易精神状态检查等内容。结果：表现有认知功能损害者26人，总的发生率为70．3％。有一项损害者14人(37．8％)，二项损害及以上者12人(32．4％)。在所测验项目中．算术发生损害率为2．7％、数字广度为5．4％、数字符号为2．7％、填图项目为2．7％、视觉再生为48．6％、词语流畅性测验为(食品名称)27％和(日用品)18．9％、连线测验为(A)18．9％和(B)21．6％、MMSE为18．9％。结论：动脉瘤性蛛网膜下腔出血本身可引起认知功能损害，以图形记忆力、注意力、额叶功能损害为主。

Neuropsychological Evaluations and Cognitive Deficits in Patients with Aneurysmal SAH

Objective: To determine the frepuency and severity of cognitive impairments associated with aneurysmal subarachnoid hemorrhage. Methods: A series of 37 patients with aneurysmal subarachnoid hemorrhage were examined by means of a battery of cognitive tests before surgical treatment. Results: In 70.3% of the patients, one or more cognitive functions were impaired. Compared with normative data, 2.7% of patients showed impairment on arithmetic, digit symbal and picture complement respectively, 5.4% on digit span, 48.6% on Visual Reproduction , 27%(food) and 18.9% (ordinary tools) on verbal fluency test, 18.9%(part A) and 21.6% (part B) on trail-making test,?18.9% on MMSE (mini mental state examination). Conclusion: The patients have impressive cognitive deficits after aneurysmal subarachnoid hemorrhage. SAH patients were especially impaired in functions that are related to short-term memory, concentration capacity, and frontocortical functions.
