title: [Environmental factors in Asperger syndrome].
abstract: This paper reviews what is currently known about the environmental factors in Asperger syndrome that is a neurodevelopmental disorder of genetic origins. Its characteristics tend to occur in families of those with the syndrome. The rate of complications during pregnancy or the neonatal period in the patients with Asperger syndrome was about the same as that in the control group. It is true that their involvement in their outer world could not influence the core social deficits very much. But it might facilitate the appearance of the second symptoms such as dissociation, anxiety, depression, persecutory delusion as well as antisocial behavior including serious criminal acts.
