Question: why does people have autisum

Keywords:

  1. Autism is a lifelong developmental disability that affects how a person makes sense of the world around them. This causes difficulties with the way they communicate with and understand other people.

    Autism is a spectrum condition which means that people with it are affected to a greater or lesser extent, though they all share certain difficulties. Some people with autism are able to live relatively independent lives but others may have accompanying learning disabilities and need a lifetime of specialist support.

    Asperger syndrome is a form of autism. People with Asperger syndrome are often of average or above average intelligence. They have fewer problems with speech but may still have difficulties with understanding and processing language.

    The causes of autism are still being investigated. Many experts believe that the pattern of behaviour from which autism is diagnosed may not result from a single cause. There is strong evidence to suggest that autism can be caused by a variety of physical factors, all of which affect brain development.

    There is evidence to suggest that genetic factors are responsible for some forms of autism. Scientists have been attempting to identify which genes might be implicated in autism for some years.

    Autism is likely to have multiple genes responsible rather than a single gene. The difficulty of establishing gene involvement is made harder by some genes working together and how they are affected by their environment. It isn’t possible therefore to create a genetic test for autism at the moment.
