I have another comment here that explains how this may happen and why blasting EMFs in your brain will do the same thing.
If I had ADHD the first thing I would try is B6 in the form of P5P: https://pubmed.ncbi.nlm.nih.gov/24321736/
There are many genetic and environmental causes to ADHD though, so I am in no way saying that a B6 issue is a cure all. But if you have high Homocysteine it could be a sign you need B6.
