Effect of Vitamin D Supplementation on Brain Waves in Female Major Depressive Disorder Patients With Hypovitaminosis D
Effect of Vitamin D Supplementation on Brain Waves in Female Major Depressive Disorder Patients With Hypovitaminosis D : A Quantitative Electroencephalogram Analysis
調査の概要
詳細な説明
Objective To evaluate the effect of vitamin D supplementation on quantitative EEG parameters in female MDD patients with hypovitaminosis D.
Methods This experimental study (self-controlled trial) will be conducted by the Department of Physiology, Bangladesh Medical University, Shahbagh, Dhaka from September 2025- August 2026. For this study, a total number of 39 female patients with MDD (age 20-40 years) will be enrolled as study participants according to selection criteria. DASS-21 scoring and baseline EEG will be recorded (pre vitamin D group). After that the participants will be supplemented vitamin D capsule (50,000IU/week) for 8 weeks. After completion of 8 weeks, DASS-21 scoring and EEG will be recorded and that will be designated as post vitamin D group.
To analyze brain electrical activities, the band power of alpha, beta, theta, and delta brainwaves will be measured using an EEG Data gathering Device, the EEG Traveler BrainTech 32+ CMEEG-01 from India. The BT40 analysis software will be used to perform power spectral analysis of the EEG Data. Mean ± SD will be used to express the Data. For statistical analysis, if data are normally distributed, to compare the mean values between the pre intervention and post intervention sessions, recorded as pre vitamin D group and post vitamin D group, paired- samples t test will be done. The P value of ≤0.05 will be accepted as statistically significant. SPSS for Windows (version 25) will be used for the statistical analysis.
The findings of this study are expected to provide quantitative evidence regarding the neurophysiological effects of vitamin D supplementation in female MDD patients with hypovitaminosis D.
