The cluster A personality disorders include paranoid, schizoid, and schizotypal personality disorders. The main characteristic of this cluster is the phenomenological similarity between the experience and behavior of the so-called odd or eccentric personality disorders and the symptoms of schizophrenia. In this article, we discuss the phenomenology and clinical course of schizoid and schizotypal personality disorders. Additionally, the most recent neurobiological findings related to both personality disorders are presented, taking neuropsychological results into consideration. Finally, we review the psychopharmacological and/or psychotherapeutic treatment of these disorders and discuss some possible directions for future research.
