Vitamin D Status and Cognitive and Functional Outcomes in Patients With Traumatic Brain Injury

Abstract

The purpose of this literature review is to explore the associations between vitamin D status and cognitive and functional outcomes in patients with traumatic brain injury who present in the outpatient or rehabilitation setting. The findings from 3 observational studies showed that while vitamin D deficiency is prevalent in this population, the associations between vitamin D status and cognitive and functional outcomes are not consistent. Limited evidence suggests that patients with traumatic brain injury in the outpatient or rehabilitation setting have increased incidence of vitamin D deficiency and, as such, may benefit from monitoring of laboratory assays and supplementation as needed.
