Moving on: autism and movement disturbance.

Many authors have reported on the presence of movement disturbance symptoms in some individuals with autism. Typically, these symptoms have been seen as peripheral to autism or as belonging to a co-occurring syndrome. Some have dismissed these symptoms as having no apparent impact on the presence of behaviors defined as the core characteristics of autism. In this article we considered the relation between symptoms of movement disturbance and symptoms of autism and included our speculative and exploratory analyses of shared symptoms. The analyses point out the difficulties posed by current definitions of autism. We proposed that symptoms of movement disturbance can affect a person's experience of life and how he or she may be perceived by others.
