Autism and Risperidone

Why do drug companies want to give Risperidone to children with autism instead of Valerian?


From Wikipedia:

“Risperidone (/rɨˈspɛərɨdn/ ri-spair-i-dohn) (trade name Risperdal, and generics) is an atypical antipsychotic drug which is mainly used to treat schizophrenia (including adolescent schizophrenia), schizoaffective disorder, the mixed and manic states associated with bipolar disorder, and irritability in people with autism.

Risperidone belongs to the class of atypical antipsychotics.[2] It is a dopamine antagonist possessing antiserotonergicantiadrenergic andantihistaminergic properties.”

My daughter has autism. I have speculated for a year or so now that she may have childhood onset schizophrenia as well as autistic symptoms. She is non-verbal, disorganized in thinking, irritable, and has mood swings.
