I have Seizures and delusions related to my Autism. This is a related link on autism use of ritalin and psychosis.
“Using high doses of methylphenidate has been reported to cause serious complications, such as psychosis, seizure, liver damage, and cardiovascular side effects. Previous studies have suggested that psychotic symptoms may be found following methylphenidate consumption in patients with ADHD.” Google
