Risperdal was recently approved for treatment of aggression and mood lability with Autism. Unfortunately, for the psychiatric community it was nothing new. We have been using antipsychotics for treatment of the symptoms of autism for years. There is one positve however, there is hope that this might mean more pharmaceutical monies directed toward treatment of autism spectrum disorders.
Autism is a complex disorder that is confusing and poorly understood at the present. So far we know there are some complex genetics involved, there may be a predisposition that is triggered by something, (eg like MMR vaccine), there is a bowel connection with inflammatory bowel wall and frequent bowel issue like chronic constipation and there may be nutritional issues with casein, gluten intolerances and magnesium ?deficiency. At this point we have to address as many issues as we identify: sensory, dietary, bowel, communication, social, need for supplements, etc. Hopefully, in 5-10 years we'll look back and wonder why we had it all wrong and were grabbing at straws. We have to do the best we can with what we have.
