Childhood autism is mainly based on behavioral training, and there are no effective oral medications or surgical treatments available. Childhood autism is mainly treated with behavioral training, such as ABA therapy, or Applied Behavioral Analysis, which is a physiologically based intervention therapy that promotes interpersonal relationships, develops life and learning skills, and is effective for autism. The core part of ABA is the task breakdown technique, and there are 4 steps in a typical task breakdown technique: instructions from the trainer, the child’s response, the response to the child’s response, and the pause. There are other home training methods for autism in children, and it is recommended to visit a hospital in time for treatment under the guidance of a doctor.
