Although the "World Autism Day" has passed, the call for attention to autistic children continues. Professor Wu, director of the Children's Developmental Behavior Research Center of the School of Public Health of Harbin Medical University and president of Heilongjiang Autistic Children Rehabilitation Association, issued an appeal to let autistic children get out of loneliness. The 6-year-old boy is obviously slow in language development and can't open his mouth yet. He never communicates with his parents, but only focuses on his own world. He is particularly interested in remote control, clocks and other things, likes watching advertisements, and is willing to walk in circles on the ground. He has a good memory in some aspects, but his understanding ability is very low, and he often can't express his meaning. Autism is included in mental disability. Autism, also known as autism, is a widespread and serious developmental disorder of children, which is characterized by interpersonal communication disorder, abnormal communication, speech retardation, limited interest and activities, rigid and repetitive behavior. This disease usually manifests itself before the age of 3 and will have a lifelong impact on patients. At present, the etiology of autism is not clear, and it is speculated that it is related to many factors such as heredity, infection and immunity. It is an indisputable fact that childhood autism has now surpassed the prevalence of cerebral palsy and Down syndrome, and has developed from a rare disease in the past to a more common developmental disorder. Because of its particularity and seriousness, children with autism have aroused widespread concern in the whole society. At the beginning of 2007, China Disabled Persons' Federation explicitly listed autism as a mental disability. Early detection of children's abnormal autism children have several obvious manifestations, and parents and teachers should pay attention to it and find the abnormalities of these children as soon as possible. Social barriers: Autistic children like to play alone, are unwilling or don't know how to play with children, and can't participate in cooperative games. He often turns a deaf ear to most of his parents' demands, but he will happily carry out some instructions he is interested in, such as going to the streets, throwing garbage, eating cookies and so on. They look at parallax and are generally not afraid of strangers. I often hold my parents' hands and go somewhere when necessary, but I seldom take the initiative to seek their parents' care or comfort. Language barrier: This is the main reason for most autistic children to see a doctor. There are many forms of language barriers. Most children are backward in language development, usually unable to speak when they are two or three years old, or have language retrogression after normal language development; Some children have language ability, even too much language, but the language lacks communication, showing meaningless and repetitive rigid language, or talking to themselves. Imitation of speech and parroting are common, and personal pronouns such as "you, me and him" cannot be used correctly. Narrow interest and repetitive stereotyped behavior: Autistic children may not be interested in most children's favorite activities and things, but they show extraordinary enthusiasm for some special objects or activities, and thus show such repetitive stereotyped behaviors or actions, such as turning around, sniffing around, playing with switches, running back and forth and arranging toys and blocks, and dancing with their hands. They are also particularly attached to something, such as watching TV advertisements or weather forecasts repeatedly and listening to one or several special music, but they are usually not interested in cartoons. Others: About 70% of autistic children are mentally retarded, 20% are in the normal range, and about 10% are mentally abnormal. Some autistic children can show strong ability in some aspects, especially mechanical memory of numbers, routes, license plates, years and so on. Hyperactivity and distraction are obvious in most autistic children, and often become the main concern of parents and doctors, so they are often misdiagnosed as ADHD. In addition, autistic children generally have behaviors such as losing temper, attacking and self-injury, which may be related to incorrect parenting styles. "For children with autism, treatment and training before the age of 5 is the key. Early intervention can make about half of the children return to normal. " In Wu Shuo, at present, special education and training are mainly used in clinic, supplemented by drugs. How should parents treat autistic children in their daily lives?
