Autism, or loneliness, is a disorder that is difficult to return to normal, can be partially restored with treatment, and usually has a poor prognosis without effective intervention. Autism is a mental developmental disorder, which is difficult to cure. After early and reasonable rehabilitation training and education and other treatments, some autistic people can recover their living ability as they grow older, but due to the different severity of the disease, the timing of the treatment and other factors, there are individual differences, and can not determine the specific recovery time. If autistic people do not receive early and effective treatment, it may affect language development and interpersonal communication, and in adolescence, it is easy to develop irritability, depression, and even self-injury and aggressive behavior. Diagnosed autism should be actively treated under the guidance of a doctor to avoid delaying the condition.
