Schizotypal personality disorder: a current review

Area of Science:

• Psychiatry
• Clinical Psychology
• Neuroscience

Background:

• Schizotypal personality disorder (SPD) is clinically significant due to under-recognition, misdiagnosis, and functional impairment.
• SPD serves as a crucial intermediate phenotype for schizophrenia spectrum disorders, aiding research into related psychotic illnesses.

Purpose of the Study:

• To review recent findings on SPD, covering epidemiology, genetics, cognition, social-affective disturbances, and neurobiology.
• To examine treatment challenges and clinical recommendations for SPD.
• To identify future research directions for SPD.

Main Methods:

• Literature review of recent findings on schizotypal personality disorder.
• Synthesis of data on epidemiology, genetics, cognitive and social-affective impairments, and neurobiology.
• Analysis of treatment challenges and clinical management strategies.

Main Results:

• SPD is associated with significant functional impairment and cognitive deficits, particularly in working memory.
• Genetic and neurobiological factors contribute to SPD, linking it to schizophrenia spectrum disorders.
• Treatment remains challenging, necessitating tailored clinical approaches.

Conclusions:

• Further research into SPD's epidemiology, genetics, and neurobiology is essential.
• Improved diagnostic and treatment strategies are needed for effective clinical management of SPD.
• Understanding SPD is key to advancing the study and treatment of psychotic disorders.
