**9. Personality disorder as a developmental disorder**

A not insignificant number of personality disorders are developmental disorders. This will require further research. One example is schizoid personality disorder. Another is paranoid personality disorder and, another, borderline personality disorder. Obsessive compulsive personality disorder could be also included in this group. There's quite a good case for narcissistic personality disorder to be included. An older term, anankastic personality disorder [39], could also be included. Many individuals with psychopathy have a developmental disorder, and a group of these have been called criminal autistic psychopathy [40]. There is a clear overlap between psychopathy and autism spectrum disorders. This is despite some research showing that persons with psychopathy have good theory of mind skills, while persons with autism don't. Nevertheless, more recent research has shown that particularly persons with high IQ can have good theory of mind skills while, at the same time, having autism.
