Hello Sharon, sorry about what you are going through, my son had severe seizures for many years, I was blessed, he had activity on both sides of the brain and after puberty, nada.. I had heard of this and prayed for it and was blessed,

Praying for you for strength endurance and some relief from the issues a hand, praying for your son to find an answer soon, sure wish I had magical words, all I have is prayers and a long distance
