No Association between Serum 25-Hydroxyvitamin D<sub>3</sub> Level and Performance on Psychometric Tests in NHANES III

Abstract

Lower 25(OH)D levels were not associated with impaired performance on various psychometric measures. While it remains to be seen if chronic exposure to low 25(OH)D levels alters brain function in the long term, this cross-sectional study suggests that 25(OH)D levels do not influence neurocognitive performance.
