Vitamin D3 effects on brain waves in men with epilepsy and low vitamin D
Effect of Vitamin D3 Supplementation on Brain Waves in Male Epileptic Patients With Hypovitaminosis D: A Quantitative Electroencephalogram Analysis
NA · Bangladesh Medical University · NCT07096414
This will test whether taking high‑dose vitamin D3 weekly for 8 weeks changes brain wave patterns in men (age 20–40) who have epilepsy and low vitamin D levels.

What this trial studies
This is a single‑site, self‑controlled pretest–posttest interventional trial enrolling 15 men with epilepsy, BMI 20–24 kg/m², on enzyme‑inducing antiepileptic drugs and with serum 25(OH)D <30 ng/mL. Baseline serum 25(OH)D and quantitative EEG (QEEG) band power (delta, theta, alpha, beta) will be recorded, then participants will receive oral vitamin D3 50,000 IU once weekly for 8 weeks. After 8 weeks the serum 25(OH)D and QEEG will be repeated and changes in band power will be compared within each participant. EEG data will be collected using the EEG Traveler BrainTech 32+ CMEEG-01 device and analyzed with BT40 software, and the study is conducted at Bangladesh Medical University in Dhaka.
Who should consider this trial
Good fit: Men aged 20–40 with a neurologist‑diagnosed epilepsy, BMI 20–24 kg/m², on enzyme‑inducing AEDs for 6 months–2 years, and with serum 25(OH)D <30 ng/mL, who are otherwise medically well, are ideal candidates.
Not a fit: Patients with absence seizures, those taking excluded AEDs (e.g., valproate, levetiracetam, lamotrigine), smokers, heavy alcohol users, or people with hypertension, thyroid disease, diabetes, or renal disease are excluded and unlikely to benefit from these specific results.
Why it matters
Potential benefit: If successful, correcting vitamin D deficiency could improve brain electrical activity in men with epilepsy and suggest a simple adjunctive approach to support neurological health.
How similar studies have performed: Some observational and mechanistic studies suggest vitamin D can affect neuronal excitability and seizure risk, but randomized or QEEG‑focused trials are limited and results are mixed.
