Project Details

While low levels of serum vitamin D are common in patients with cognitive impairment and stroke, there has been little investigation on the associations between levels of vitamin D and post-stroke cognitive impairment. The aim of this study is to determine the relationship between vitamin D and post-stroke cognitive impairment. We hypothesize that low levels of vitamin D on admission would be significantly associated with lower cognitive functioning in post stroke subjects. A consecutive series of 100 first acute ischemic stroke patients (Mild stroke, NIHSS less than 5, no known cognitive impairment prior to the index stroke) will be recruited and followed up for one month. Serum levels of vitamin D will be measured within 24 hours of admission. All demographic characteristics (age, gender, marital status, economic status), level of stroke severity (National Institute of Stroke Severity Scale), stroke outcomes (modified Rankin score and Barthel Index), and cognitive functioning (MOCA) will be collected. In addition, 100 healthy subjects will be recruited as controls, with measurement of serum vitamin D levels taken and non-stroke related assessments administered (i.e., MOCA) for comparison.
