Well now the picture gets more complicated. I thought we were dealing with just a developmental problem. Then came the sinusitis and Chiari. Now today I found out that my 4.5 y.o son has ventricular septal defect and tricuspid and mitral insufficiency. Can anything else go wrong with the poor kid? He was showing so much improvement on Risperdal and Adderall. With the news stories about Adderall though, I am scared to give him any more. I forgot to ask the P.A. about it on the phone, but I can't take the risk. Hopefully the Risperdal will help enough in school. I just thank God we got referred to this current dr.(genetic spec.) and found all this out!
