Abstract：Objective To investigate the influential factors of cognitive dysfunction in patients with aneurysmal subarachnoid hemorrhage(aSAH).Methods The clinical data of 268 patients with aSAH were analyzed retrospectively.Cognitive function was evaluated using the Montreal Cognitive Assessment(MoCA)at 6 and 12 months after onset,and the relevant factors affecting cognitive dysfunction were analyzed based on the presence or absence of cognitive impairment.Results There were 112 patients(41.79%)with cognitive dysfunction at postoperative 6 months and 53 patients(19.78%)with cognitive dysfunction at 12 months postoperatively.With the prolongation of postoperative time,the incidence of cognitive dysfunction gradually decreased.Statistical analysis showed that the preoperative Hunt-Hess grade＞Ⅲ,the modified Fisher grade＞Ⅱ,combined cerebral infarction and hydrocephalus were the influential factors of cognitive dysfunction in patients with aSAH.Conclusions The incidence of cognitive impairment is relatively high in aSAH patients.Patients with high preoperative Hunt-Hess grade,modified Fisher grade,cerebral infarction,and hydrocephalus aSAH may be more likely to have cognitive dysfunction.Patients with the above high-risk factors should be identified and clinically intervened as soon as possible to improve cognitive dysfunction.
