My difficult child is BiPolar (BP) & has been on Risperdal for about nine months. He has really been doing well on it as far as behaviors and NO big rages. Other than weight gain issues, he has tolerated this medication well. The last couple of months he has been complaining that his legs feel really weird. He has trouble discribing what they feel like but he is really bothered by it. He say his legs don't want to work. He lays on the floor hitting his legs with his fists then starts getting very aggitated and the behavior gets ugly. BUT...alot of times this is when he's bored or tired. Today while grumping on the floor, complaining about his legs and everything in his life that sucks...I suggested that he call a friend and invite him over. "oh! okay". An hour later he is on the couch with his friend playing his gameboy. I asked how his legs are feeling and he says they're better. Hmmmmmm...Has anyone else experienced this leg thing? One more question...The psychiatrist might want to change my difficult child from Risperdal, because of a big weight gain issue, to Abilify? Is Abilify a good medication for Bipolar children?
