Effect of Vitamin D Supplementation on Brain Waves in Female Major Depressive Disorder Patients With Hypovitaminosis D

Sponsor: Bangladesh Medical University

Summary

Major Depressive Disorder (MDD) is a common mood disorder characterized by persistent sadness, loss of interest and cognitive impairment. Emerging evidence suggests that vitamin D may exert neuroprotective and mood-regulating effects by influencing serotonin synthesis, modulating inflammation and supporting neuronal function. Vitamin D deficiency is frequently observed in MDD patients and has been linked to greater symptom severity and poorer treatment outcomes. Quantitative electroencephalography (QEEG) is a non-invasive tool for assessing brain electrical activity. Alterations in QEEG pattern such as increased theta and reduced alpha power have been reported in patients with MDD , reflecting disrupted cortical processing and emotional regulation. Although interest in the role of vitamin D in mental health is increasing, the direct effect of vitamin D supplementation on QEEG parameters in MDD patients with hypovitaminosis D is not well explored. This study aims to evaluate whether vitamin D supplementation can modulate brain wave activity in female patients with MDD and hypovitaminosis D. Therefore providing insight into its neurophysiological and therapeutic significance.
