Does anyone know anything about the process? My son is on the NHS waiting list for ADHD. I was asviced to go private as NHS is quite long.. anyways went for private assesment and its come back that he does have ADHD. They want to medicate him, but im.worried incase they medicate him but NHS come and want to see him but hes medicated? Or do the NHS accept private assesments? Does anyone know how this works?
