my son is 2 1/2 yrs old,diagnosed with global dev delay,he goes through these spells of screaming and constantly hurting himself and anyone around him,he has turned real mean,they have him on
risperdal,lorazapham,clonazepam,and haldol,the only one that seemed to have a little effect was the clonazepam,but its still to early to know on that one since they just started it yesterday,.
