Summary

This review covers biological treatments for obsessive-compulsive disorder (OCD), including serotonin reuptake inhibitors (SRIs) and strategies for treatment-resistant OCD. It also discusses matching treatments to patient symptom clusters and managing medication duration.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Pharmacology

Background:

  • Obsessive-compulsive disorder (OCD) has two primary evidence-based treatments: exposure and response (ritual) prevention (EX/RP) and pharmacotherapy with serotonin reuptake inhibitors (SRIs).
  • This article, the third in a series, focuses on the biological treatment modalities for OCD.

Purpose of the Study:

  • To review the efficacy of serotonin reuptake inhibitors (SRIs) as monotherapy for OCD.
  • To discuss strategies for managing treatment-resistant OCD using various pharmacological and somatic therapies.
  • To explore patient-treatment matching based on symptom clusters and provide guidance on maintenance and termination of treatment.

Main Methods:

  • Review of existing literature on the efficacy of SRIs (clomipramine and SSRIs) for OCD monotherapy.

Related Experiment Videos

  • Discussion of treatment-resistant OCD strategies, including combination therapies, augmentation, and intravenous clomipramine.
  • Examination of other somatic therapies such as electroconvulsive therapy, neurosurgery, and transcranial magnetic stimulation.

    • Main Results:

    • Evidence supports the efficacy of clomipramine and SSRIs as monotherapy for OCD.
    • Various strategies exist for treatment-resistant OCD, including combining EX/RP with SRIs, combining different antidepressants, augmentation, and alternative somatic therapies.
    • Research is ongoing regarding optimal treatment selection based on symptom clusters and management of long-term treatment.

    Conclusions:

    • SRIs are a cornerstone of biological treatment for OCD.
    • A range of options are available for treatment-resistant OCD, requiring careful consideration of individual patient factors.
    • Further research is needed to refine treatment selection, duration, and discontinuation protocols for OCD.
