The effect of vitamin D supplementation on the brain mapping and behavioral performance of children with ADHD: a double-blinded randomized controlled trials.

What Was Tested

This randomized controlled trial looks at Vitamin D, K2, Magnesium and Zinc.

This study aimed to investigate the concomitant effects of Vitamin D3 supplementation and Neurofeedback on children with ADHD.

Why It Was Studied

Attention deficit hyperactivity disorder (ADHD) is one of the common neurodevelopmental diseases that are accompanied with EEG pattern changes and Low levels of 25-hydroxyvitamin D [25(OH)D].

Neurofeedback provides a feedback signal to alleviate brain wave abnormalities and offers an alternative therapy for ADHD.

Who Took Part

The age groups tagged for this paper are children, both men and women.

This study was implemented on children with an established diagnosis of ADHD who received multisession Neurofeedback therapy.

How the Study Was Run

In design terms this was a randomized, double-blind and placebo-controlled study.

Because people in this Vitamin D, K2, Magnesium and Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Blinding on both sides kept the participants and researchers unaware of who received Vitamin D, K2, Magnesium and Zinc.

A placebo (an inactive look-alike) gave the Vitamin D, K2, Magnesium and Zinc group a baseline to be compared against.

The background rhythm was measured using quantitative EEG both before and at the end duration of the therapy.

What Was Measured

Attention deficit hyperactivity disorder (ADHD) is one of the common neurodevelopmental diseases that are accompanied with EEG pattern changes and Low levels of 25-hydroxyvitamin D [25(OH)D].
