Definition: Autism is a general term for a group of complex disorders of brain development. These disorders are characterized, in varying degrees, by difficulties in social interaction, verbal and nonverbal communication and repetitive behaviours. In recent times all autism disorders were merged into one umbrella diagnosis of Autism spectrum disorders (ASD).
Symptoms and Treatment: Autism spectrum disorders (ASD) are characterized by social-interaction difficulties, communication challenges and a tendency to engage in repetitive behaviors. However, symptoms and their severity vary widely across these three core areas. Taken together, they may result in relatively mild challenges for someone on the high functioning end of the autism spectrum. Each child or adult with autism is unique so, each autism intervention plan should be tailored to address specific needs. Intervention can involve behavioral treatments, medicines or both. Many persons with autism have additional medical conditions such as sleep disturbance, seizures and gastrointestinal (GI) distress. Addressing these conditions can improve attention, learning and related behaviors.
Statistics: In China disease statistics were resulted as while behavioral treatment research often targets cognitive functioning and is beginning to show promise for improving outcome areas relating to core symptoms such as language, measurement issues in assessing improvements of core symptom severity must be addressed systematically before behavioral, pharmacological, or combined treatments can be rigorously tested through trials. Simultaneous to this (and noted above) is the continued search for neurochemical targets for drug intervention and biological predictors of response; and development of efficacious therapies not only for the core symptoms of autism, but also for associated morbidities, such as sleep disturbances, GI symptoms, and others.
