Stereotactic ablation surgery for treatment-resistant obsessive-compulsive disorder: Technical evolution, clinical...

Area of Science:

• Neurosurgery
• Psychiatry
• Neurology

Background:

• Obsessive-compulsive disorder (OCD) is a prevalent and disabling psychiatric condition.
• Treatment-resistant OCD poses a significant clinical challenge, with many patients unresponsive to standard therapies.
• Stereotactic ablation surgery is an established neurosurgical intervention for severe OCD, targeting implicated neural circuits.

Purpose of the Study:

• To systematically review the technological advancements in stereotactic ablation for OCD.
• To evaluate the mechanisms, efficacy, and safety of various stereotactic ablation techniques.
• To provide a framework for future physical interventions in severe OCD management.

Main Methods:

• Systematic review of stereotactic ablation technologies.
• Analysis of radiofrequency ablation, laser interstitial thermal therapy, radiosurgery, and focused ultrasound.
• Evaluation of underlying mechanisms, therapeutic efficacy, and safety profiles.

Main Results:

• Stereotactic ablation techniques have evolved significantly over time.
• These interventions demonstrate efficacy in alleviating OCD symptoms by disrupting specific neural circuits.
• Safety profiles and potential risks associated with each technique are detailed.

Conclusions:

• Stereotactic ablation provides a valuable option for severe, treatment-resistant OCD.
• Understanding the evolution and outcomes of these techniques is crucial for clinical decision-making.
• Further development aims to enhance the safety and effectiveness of physical interventions for OCD.
