Effect of Antiplatelet Therapy on Cognition After Aneurysmal Subarachnoid Hemorrhage

Effect of Antiplatelet Therapy on Cognition After Aneurysmal Subarachnoid Hemorrhage

Deficits in memory, executive function, and language are common cognitive sequelae of aneurysmal subarachnoid hemorrhage (aSAH). Previous study demonstrated that post-treatment antiplatelet therapy reduced risk for delayed cerebral ischemia caused by aSAH. However, the effect of antiplatelet therapy on cognition after aSAH is unclear. The aim of this study was to assess the effect of antiplatelet therapy on cognition after aSAH.

Inclusion Criteria:

• 1. Patients with SAH in whom the aneurysm was proven by conventional angiography; 2. Baseline Hunt-Hess grade I-III; 3. patients received endovascular treatment

Exclusion Criteria:

• 1. Hunt-Hess grade IV-V; 2. Non-aneurysmal SAH; 3. Dementia in other diseases; 4. Lacking of 6-8 month MoCA evaluation.
