Hi my son is so hard to handle he has ADHD the hyperactive impulsive type and he has ODD and sensory integration dysfunction. HE also over the past 6months starting saying he wanted to kill himself. He has been hospitalized for that and he started to hit his head against the wall. Sometimes he hits his chest face when hes upset about something. He also has a speech problem loves routine he social at times but cannot seem to make any friends he often will just tell them what he likes or whats going on instead of really sharing a conversation. He also hums and chews on his shirts or whatever he can find to put in his mouth. He has serious meltdowns multiple times a day. Hes very defiant and he hits his one year old brother, me, the babysitter and other kids. He also smiles when he is in trouble like he cant control his facial expressions. he does play with toys and just makes weird shooting sounds and he likes to run in circles sometimes for a while. I think there is something else wrong with my son. He going for an evaluation a childrens memorial hospital in chicago on july 30 I hope they can give me an answer because I know theres something else going on. His doctors have said possibly Pervasive Developmental Disorder (PDD)-not otherwise specified, aspergers, bi-polar disorder I feel overwhelmed and lost.
