NCT06360991

Brief Summary

The primary purpose of this study is to investigate the effect of deep brain stimulation (DBS) implantation targeting the anteromedial region of subthalamic nucleus (amSTN), or nucleus accumbens (NAc), or bed nucleus of the stria terminalis (BNST), or ventral capsule/ventral striatum (VC/VS), or the ventral anterior limb of the internal capsule (vALIC) in patients with treatment-resistant obsessive-compulsive disorder (TR-OCD).

Outcome Measures

Primary Outcomes (1)

  • Yale-Brown Obsessive Compulsive Scale (Y-BOCS): the change from baseline to 1 year in the Y-BOCS total score.

    The Y-BOCS scale is a clinician-rated, 10-item scale, each item rated from 0 (no symptoms) to 4 (extreme symptoms), yielding a total possible score range from 0 to 40. The total score is usually computed from the subscales for obsessions (items 1-5) and compulsions (items 6-10). The results can be interpreted based on the total score: 0-7 is sub-clinical; 8-15 is mild; 16-23 is moderate; 24-31 is severe; 32-40 is extreme.

    1 year

Secondary Outcomes (9)

  • Yale-Brown Obsessive Compulsive Scale (Y-BOCS): remission, response, and partial response rate

    Week 2, Month 1, Month 3, Month 6, and Month 12

  • Hamilton Anxiety Scale (HAMA): the change from baseline to 2 weeks, 1 month, 3 months, 6 months, and 1 year in the HAMA total score.

    Week 2, Month 1, Month 3, Month 6, and Month 12

  • Hamilton Depression Rating Scale (HAMD-17): the changes of HAMD-17 scores and its subscales from baseline to 2 weeks, 1 month, 3 months, 6 months, and 1 year.

    Week 2, Month 1, Month 3, Month 6, and Month 12

  • Pittsburgh Sleep Quality Index (PSQI): the change of PSQI from baseline to Week 2, Month 1, Month 3, Month 6, and Month 1.

    Week 2, Month 1, Month 3, Month 6, and Month 12

  • Clinical Global Impression-Severity (CGI-S): the change from baseline to 2 weeks, 1 month, 3 months, 6 months, and 1 year in Clinical Global Impression-Severity (CGI-S)

    Week 2, Month 1, Month 3, Month 6, and Month 12

  • +4 more secondary outcomes

Study Arms (1)

treatment-resistant obsessive-compulsive disorder (TR-OCD).

EXPERIMENTAL

Patients will undergo bilateral DBS lead implantation.

Device: Deep brain stimulation (DBS)

Interventions

The DBS lead is stereotactically introduced into the target in the brain (vALIC, BNST, amSTN, VC/VS, or NAc) and fixed to the skull; the lead is then connected to a neurostimulator implanted subcutaneously in the subclavicular region.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:
