Autism is a developmental disability so it doesn't directly respond to medication but there can be accompanying psychiatric disabilities that do. A trained child psychiatrist would have a good understanding.
Childhood schizophrernia does exist but that sounds more like autism from what you are describing which is much more common. Only a psychiatrist can make a diagnosis but I'd perhaps seek a second opinion.
