Currently, rehabilitation training is recognized at home and abroad as one of the most effective ways to improve the core symptoms of autism in children and to improve the quality of life of patients, with the goal of promoting language development, improving social interaction skills, and mastering basic life skills and learning skills. There is also psychotherapy, which aims to reinforce good behaviors, correct abnormal behaviors that affect education, training, social interaction and endanger oneself, such as stereotypical behaviors, aggressive behaviors, injurious behaviors and disabling behaviors, as well as symptoms that are accompanied by obvious psychotic symptoms, or threaten the safety of oneself or others, or interfere with the patient’s education and rehabilitation training, and affect daily life. Risperidone, for example, can improve psychotic symptoms such as wounding, aggressive and destructive behavior, hallucinations and delusions, and Ritalin can be used for autistic patients with combined attention deficit and hyperactivity symptoms.
