Effect of Antiplatelet Therapy on Cognition After Aneurysmal Subarachnoid Hemorrhage

Overview

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.
