Vitamin D Status and Cognitive Performance of Post Stroke Patients

Abstract
Background: The prevalence of post-stroke cognitive impairment (PSCI) ranges from 20-80%. Some studies found that vitamin D deficiency was common in stroke patients, yet the relationship with cognitive performance remains unclear. The study aimed to investigate the relationship between levels of vitamin D and cognitive performance in post-stroke patients.Materials and Methods: This was a cross-sectional study with 20 post-ischemic stroke patients. Vitamin D levels were measured using enzyme-linked fluorescent assay (ELFA). The cognitive performance was assessed by computerized mini-mental state examination (MMSE) and clock drawing test (CDT). The relationship between vitamin D levels and cognitive tests were performed using paired T-test.Results: Vitamin D insufficiency (
