There are new treatments for people that do not repond to medication. I'm not sure the name however is based on magnetic frequencies to the brain. It does not have any side affects and it seems to work well. You would have to get online search where these treatments are offered. I'm in Florida and I believe its offered here in some hospital, not sure where. If nothing else work is worth trying it if offered in your area. Good Luck and God help you and you son.
