There are no meds for autism. Most psychiarists spend 15 minutes with the patient andwrite a refill. A psychologist specializes in diagnosing and teachi:ng coping skills. ADHD and psychosis are co-morbid disorders treatable with meds. Not everyone on the spectrum has them. A psychologist will spend 3 hours on an evaluation. An MD psychiatrist can see 12 patients in that time and bill accordingly. He will usually have an LCSW make the diagnosis anyway or worse an MS clinician under his employ. While he may sign the evaluation, it just isnt cost effective for him to actually perform it.
