My son Kevin has been diagnosed with autism and schizo-affective disorder. I believe that much of his psychotic behavior is due to seizure disorder. Caren Haines has written an informative book called “Silently Seizing.” In the book Caren states that up to 70 percent of autistic people may have seizures. These are lodged deep in the brain and may not be apparent with an EEG. I will be writing a book review soon.
