Pediatric autism is also known as autism. The incidence of autism has been increasing in recent years, which is why it has become a growing concern for medical professionals and parents. Pediatric autism has three main symptoms: social interaction disorders, verbal and nonverbal communication disorders, and narrow interests and stereotyped behaviors. The majority of children are seen by parents because they have a speech and language communication disorder. The interaction disorder is a core symptom of autism. The child lacks communication or communication skills with others, lacks eye contact with loved ones, does not like or know how to play with children, cannot participate in cooperative play, and generally rarely actively seeks parental care or comfort. The child has a particular interest and stereotypical behavior at some point, mainly in the form of stereotypical body movements and unusual ways of preferring objects and toys. Approximately 50% of children with autism have a combination of mental retardation and 50% have normal or exceptional intelligence. Most children with autism have sensory abnormalities, a fear or preference for certain sounds, a fear of certain visual images, or a preference to look at certain objects in a particular way. Also hyperactivity and distractibility are common in most children with autism. The ABC scale as a screening tool and the CARS scale as a diagnostic tool have been used in China to diagnose autism, and the treatment of autism is based on educational training, supplemented by psychotropic medication.
