Doctors and psychologists diagnose ASD by evaluating the patient’s history and monitoring their behavior. Developmental pediatricians are medical doctors who have the training and experience to diagnose autism and other developmental difficulties. These professionals consider the medical and psychosocial elements of children’s behavior problems and offer counsel and treatment accordingly. Child psychiatrists are doctors who diagnose and treat many behavioral disorders in children. Psychiatrists contrast from psychologists in that they are licensed physicians and they can prescribe medication while psychologists cannot. Also, pediatric neurologists can diagnose autism as they are doctors who treat children with conditions caused by problems in their nervous system.
