Abstract

The apolipoprotein E4 allele (APOE4) associates with increased dementia risk, and hypertension may associate with mild cognitive deficits. We examined whether nondemented stroke patients with (1) a prestroke history of hypertension and (2) APOE4 were more cognitively impaired at 3 months after stroke. A total of 257 participants were genotyped and outcomes from neuropsychological evaluations analyzed using regression. Total Cambridge Assessment for Mental Disorders in the Elderly (CAMCOG) and speed of working memory significantly associated with hypertension. No outcomes significantly associated with APOE4. Subjects with prestroke hypertension had more impaired global cognition and slower access to information held in working memory.
