Autism in children and adolescents is a mental and psychological disorder that is becoming more prevalent and more important in modern society. Autism is characterized by an obsession with one’s own world and an unwillingness to interact with others. The complex nature of autism causes autism to be difficult to treat. The parents of autistic children in the family are very important, parents need to do the following: 1, the mother should pay attention to pregnancy health care, strengthen perinatal health care, and actively carry out eugenics work. Viral infections during pregnancy, pre-eclampsia, birth asphyxia and cesarean section can affect young children. Viral infections in mothers during pregnancy, especially in the first three months of pregnancy, can lead to abnormal fetal brain development and cause autism in children. For example, rubella virus, herpes simplex virus, influenza virus and cytomegalovirus can damage the central nervous system of the affected child and cause the disease. Therefore, pregnant women should be careful not to contract viruses during pregnancy, especially in the early stages of pregnancy. In early infancy, care should also be taken to avoid high fever convulsions, which can also cause brain damage. Parents should go to the hospital as soon as possible to see a specialist (child neuropsychiatry, psychology and health care specialist) to confirm the diagnosis of children suspected of having autism, and early diagnosis and early treatment is the key to success or failure. Since children with autism have different ages, clinical manifestations and functional impairments, treatment needs to be individualized. Before treatment, the doctor in charge and the parents will assess the child’s basic mental functions, such as language, social interaction, motor behavior and life skills, and then develop an individualized, structured and systematic treatment plan. 3. Breastfeeding is advocated because breast milk is rich in alkaline minerals that are beneficial to the child’s intellectual development. Older children should eat less sugar and more vegetables, fruits, grains and other “alkaline foods”. Pay attention to the “acid-base balance” of the diet, which is beneficial to the relative stability of the PH value in the body, so that various metabolic functions are coordinated, which in turn keeps the body and mind in a good state of health. Parents should let their children have more contact with the outside environment, participate in various exercises, and let them play, interact and learn together with children of the same age so that their personality and social adaptability can develop healthily. Once you find that your child shows signs of autism, you should consult a doctor for proper treatment and induction training. Although the cause of autism is unknown, effective treatment and prevention can be carried out. The main treatment measures include behavior therapy, education and training, such as language training, social training, sensory training, self-care training, and play activities, etc., supplemented by medication, but not every autism requires medication, and there is no special medicine for autism. During the treatment process, parents and therapists should cooperate closely and actively participate. With more teaching, more practice, constant reinforcement and long-term persistence, the child can make significant progress and the condition can be actively and effectively controlled.
