Caregiver for a 38 year old young man , Mike , having retardation with autism. 6 mos. ago he developed bahavorial disorders , puts his arms over his head and wiggles his fingers , face turns reddish and he often screams very loud while rambling on verbally. he has also recently began hitting / tapping me , Joe , with his fist. just this morning he hit his mother while she was trying to calm him down during one of his episodes. I love him dearly. His mother has some dimentia so my hands are full. plus I m on kidney dialysis :( Can you recommend a lite drug for Mikie. He has no other current health issues. I removed him from a pre-diebetic problem by lowering his body weight from 225 lbs. down to 115 lbs. in just a year. his primary says he s one healthy guy. THX , Joe Gerst
