Autism is a neurodevelopmental disorder characterized by social communication disorder, narrow range of interests or activities and repetitive stereotyped behavior. It is mainly manifested in different degrees of impairment of social skills and verbal communication skills, accompanied by certain behavioral and intellectual disorders. Experts from the Department of psychology of Tianjin Children's Hospital suggest that autism mostly begins in infancy, and developmental abnormalities and damage usually occur before the age of 3. The incidence of boys is significantly higher than that of girls, and the cause of autism is not clear. In life, if the child is found to have the following symptoms, he should go to the hospital for diagnosis in time. Social communication barriers This symptom is obvious. Children can't establish normal interpersonal relationship with others, and can't communicate with others normally. Generally, they lack friends and can't distinguish specific close and distant relationships. They treat their relatives with the same attitude as others, which are related to autism. In severe cases, it is impossible to establish normal partnerships with children of the same age, so there will be loneliness and autism. Single interests and hobbies Children will have a narrow range of interests and will not be interested in toys and games loved by normal people. Usually, some items that children don't like will show extensive interest. For example, I like to observe electric fans, bottle caps, etc., and may pay attention for a long time without boredom, but I have no interest in toys loved by normal people. These are also related to autism. Repeat the same thing People with autism usually have stereotyped behavior patterns. For example, you need to go to bed at a fixed time every day, and you like to take the same route when you go out. These behaviors are relatively rigid. If they are stopped, they usually show unhappiness, anxiety and even resistance. In addition, some children will repeatedly appear some stereotyped actions. Once these abnormal manifestations are found, we need to be vigilant against children suffering from autism. Little or no speech In the process of development, there will be language disorder, which is a common manifestation of the disease. In the process of the development of language barriers, there is usually a delay in language ability, and may still not speak at the age of two or three. With age, there may be silence, less language and low expression ability. (outlook new era)
