The evaluation and research process of cognitive impairment after aneurysmal Subarachnoid Hemorrhage / 医学研究生学报

Rupture of an intracranial aneurysm causes subarachnoid hemorrhage (SAH) occuring with a frequency of six to eight per 100 000, and has high morbidity and mortality. Cognitive dysfunction is the most common neurologic impairment after subarachnoid hemorrhage (SAH). Neuropsychological testing has been used to detect subtle cognitive impairment after SAH. However, the specific tests used often vary, and a test battery generates multiple scores that difficult to summarize and interpret. Also, detailed neuropsychological testing is invaluable for characterizing the extent and nuances of cognitive impairment in individuals. This article reviews the evaluation of cognitive impairment to further explore the mechanism and treatment.
