问题     Autism (自闭症) is a lifelong developmental disorder that affects the ways a person communicates and relates to other people. The range and intensity of disability vary widely, but all individuals affected by autism have difficulty in communication, learning and social skills. Autism usually manifests during the first three years of life. Impaired social interaction is the hallmark symptom. Many people affected by autism do not have even one friend. This is very stressful to them and to their families. Individuals affected by autism may also exhibit repeated body movements, unusual responses to people or attachments to objects, resistance to changes in routine, and extreme sensory sensitivity. This commonly includes severe reactions to noise and touch, may contribute to increased levels of anxiety and often means that significant levels of supervision are required. There is no definitive cause or cure, but specialized interventions can give individuals affected by autism the tools they need to lead full and productive lives.
    There are many different myths surrounding autism in the world. Here are some of the truths about it. Autism is not rare. The latest statistics indicate 1 in 165 Canadians is affected by autism, an increase of over 600%in the past ten years. What was once viewed as a rare disorder is now recognized as the most common neurological disorder affecting children. It is not an emotional disturbance, but a neurodevelopmental disorder. Parents do not cause autism. It’s not the fault of poor parenting. However, parents do need support to manage difficult behaviors with structure and consistency.
    People do not "grow out" of autism. With early intervention and good educational programs, progress may be significantly larger. The autistic needs to be learning, living and working in settings where there is ample opportunity to communicate and interact with others who have the skills they need.
    Although no specific cause of autism is known, current research links it to biological or neurological differences in the brain that may begin during pregnancy and shortly after birth. Research suggests there may be a genetic base to many cases of the disorder and is currently focused on several specific genes.
