Who qualifies for deep brain stimulation for OCD? Data from a naturalistic clinical sample

Area of Science:

• Neuroscience
• Psychiatry
• Neurosurgery

Background:

• Obsessive-compulsive disorder (OCD) is a debilitating mental health condition.
• Some patients with severe OCD do not respond to standard treatments.
• Neurosurgical interventions like deep brain stimulation are considered for refractory cases.

Purpose of the Study:

• To determine the proportion of treatment-seeking OCD patients meeting neurosurgery selection criteria.
• To assess the feasibility of current neurosurgical candidate screening in a naturalistic clinical setting.

Main Methods:

• Utilized baseline data from the NIMH-supported Brown Longitudinal OCD Study.
• Included adult patients with OCD undergoing treatment.
• Analyzed diagnostic information, symptom severity, and treatment histories.

Main Results:

• Only 2 out of 325 adult OCD patients met the contemporary neurosurgery screening criteria.
• The low proportion suggests current criteria may be too restrictive or require refinement.

Conclusions:

• Current neurosurgery selection criteria identify a very small subset of severe OCD patients.
• New clinical trial models and refined entry criteria are needed for neurosurgical interventions in OCD.
• Further research is essential to optimize treatment pathways for refractory OCD.
