Deep Brain Stimulation Clinical Trial
Official title:
Efficacy and Safety of Combo-stim Deep Brain Stimulation for Treatment-refractory Mental Disorders: a Multi-center, Single Arm, Prospective, Open-label, Extendable Study
This is a multi-center, single arm, prospective, open-label, extendable study for the efficacy and safety of combo-stim deep brain stimulation for treatment-refractory mental disorders (obsessive-compulsive disorder, schizophrenia, bipolar with depression, anorexia nervosa, gambling disorder and adult autism).
Total of 18 subjects from Shanghai Mental Health Center who fit inclusion and don't fit exclusion criteria are recruited to undergo neurosurgical implantation of combo-stim DBS in bilateral nucleus accumbens (NAcc) and anterior limb of internal capsule (ALIC) on a certain date, the DBS system will be turned on for stimulation and parameters adjusted 7-14 days after implantation, treatment purposes are evaluated after system has been turned on for 8-24 weeks. Primary efficacy is evaluated by change in Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Positive and Negative Syndrome (PANSS), Montgomery-Asberg Depression Rating Scale (MADRS), Body Mass Index (BMI), Autism Behavior Checklist (AuBC) score and longest consecutive days without gambling within one month. Safety is evaluated by adverse events (AE) and device-related adverse events (ADE), serious adverse events (SAE) and serious device-related events (SADE), device deficiencies (DD) and device malfunction, physical examination and vital signs, laboratory examination, electrocardiogram (ECG), imaging examination, scale evaluation and early drop out ratio due to AE. ;
