Dereistic Disorder, also known as Dereism is a proposed sub-type of the Pervasive Developmental Disorders. Major characteristics attributed to the condition are symptoms of psychosis (hallucinations and delusions) combined with problems empathizing, mild pragmatic deficits and a past history of extreme oppositional behavior during early childhood.

Insight
Dereistic Disorder is not recognized by the DSM-5 or ICD-10, the two main classification systems for mental disorder. A person with Dereism often retain insight on all their symptoms and can easily identify divergent behaviors. They might also create interpersonal relationships with peers at school but may have difficulties voluntarly sharing their interests.

Teenagers with dereism may met criteria for Autism Spectrum Disorder but symptoms are too mild to be considered as such. It may or may not exist as a separate condition from Autism.
