The exact cause of Asperger syndrome is not well understood. While it has high heritability, the underlying genetics have not been determined conclusively. Environmental factors are also believed to play a role. Brain imaging has not identified a common underlying condition. There is no single treatment, and the UK's National Health Service (NHS) guidelines suggest that "treatment" of any form of autism should not be a goal, since autism is not "a disease that can be removed or cured". According to the Royal College of Psychiatrists, while co-occurring conditions might require treatment, "management of autism itself is chiefly about the provision of the education, training, and social support/care required to improve the person's ability to function in the everyday world". The effectiveness of particular interventions for autism is supported by only limited data. Interventions may include social skills training, cognitive behavioral therapy, physical therapy, speech therapy, parent training, and medications for associated problems, such as mood or anxiety. Autistic characteristics tend to become less obvious in adulthood, but social and communication difficulties usually persist.
