Anxiety disorders frequently co-occur with schizophrenia, particularly obsessive-compulsive disorder and panic disorder. However, more research is needed to establish evidence-based treatments for these common comorbidities.

Area of Science:

  • Psychiatry
  • Clinical Psychology
  • Neuroscience

Background:

  • Anxiety symptoms are often overlooked in schizophrenia research due to diagnostic hierarchies.
  • Limited data exists on the prevalence and impact of anxiety comorbidities in schizophrenia patients.

Purpose of the Study:

  • To review current knowledge on anxiety comorbidity in schizophrenia.
  • To assess the prevalence, relevance, and treatment of anxiety disorders in schizophrenia.

Main Methods:

  • A comprehensive literature search was conducted on Medline from 1966 to July 2003.
  • Included studies focused exclusively on schizophrenia diagnoses and anxiety disorder comorbidities.

Main Results:

  • Obsessive-compulsive disorder (OCD) and panic disorder were the most frequently studied anxiety comorbidities in schizophrenia, appearing highly prevalent.

  • Posttraumatic stress disorder (PTSD) was the least studied anxiety comorbidity.
  • Limited high-quality treatment studies exist, with most suggesting conventional anxiety treatments offer some benefit.

    • Conclusions:

    • Anxiety comorbidities are common in schizophrenia, and conventional treatments may alleviate symptoms.
    • Further large-scale studies with rigorous methodologies are essential for evidence-based conclusions on anxiety treatment in schizophrenia.
