Obsessive-compulsive symptoms in schizophrenia: a review

Area of Science:

• Psychiatry
• Clinical Psychology

Background:

• Obsessive-compulsive symptom (OCS)/disorder (OCD) frequently co-occurs with schizophrenia.
• Understanding the prevalence and characteristics of OCS/OCD in schizophrenia is crucial for effective patient care.

Purpose of the Study:

• To systematically review the existing literature on the prevalence, symptom profile, and management of OCS/OCD in patients diagnosed with schizophrenia.

Main Methods:

• Conducted comprehensive electronic literature searches to identify relevant studies.
• Synthesized findings from studies reporting on OCS/OCD in various stages of schizophrenia.

Main Results:

• OCS/OCD is highly prevalent in schizophrenia patients across all disease phases, more so than in the general population.
• OCS/OCD symptom profiles in schizophrenia mirror those in isolated OCD. Co-occurrence correlates with increased schizophrenia symptom severity and poorer outcomes.
• Limited data exists on the efficacy of pharmacological and psychological interventions; some evidence suggests benefits from certain antipsychotics, antidepressants, and cognitive behavioral therapy.

Conclusions:

• OCS/OCD is a significant issue in schizophrenia, but high-quality evidence for specific management recommendations is scarce.
• Further research is needed to establish evidence-based treatment guidelines for OCS/OCD in schizophrenia.
