[Psychiatric comorbidities and secondary emotional difficulties in Asperger syndrome].

People with developmental disorders frequently have psychiatric comorbidities and problematic emotional reactions and behaviors. We commonly calls these conditions "nizi-shougai (secondary difficulties)" in Japan. But there is no clear definition of "nizi-shougai", and it is impossible to distinguish "secondary difficulties" from the problems derived from Asperger syndrome itself. In this paper, I focus on psychiatric comorbidities and emotional difficulties of Asperger syndrome. Early detection and intervention for children with developmental disorders can prevent some kind of "secondary difficulties". Treatment for Asperger syndrome should be tailored to meet individual characteristics and needs.
