Summary: we previously found that electrical stimulation in the anterior limb of the internal capsule/bed nucleus of the stria terminalis (ic/bst) alleviates depressive symptoms in severe treatment-resistant obsessive-compulsive disorder (ocd) patients. Here we tested the hypothesis that electrical stimulation in either ic/bst or in the inferior thalamic peduncle (itp) effectively reduces depressive symptoms in treatment-resistant major depressive disorder (trd). In a double-blind crossover design, the effects of electrical stimulation at both targets were compared in trd patients. The 17-item hamilton depression rating scale (ham-d) was the primary outcome measure. During the first crossover, patients received ic/bst stimulation versus no stimulation in random order (2? 1 weeks). During the second crossover (3? 2 months), patients received ic/bst versus itp versus no stimulation. Patients and evaluators were blinded for stimulation conditions. All patients (n = 7) were followed up for at least 3 years (3? 8 years) after implantation. Six patients completed the first crossover and five patients completed the second. During the first crossover, mean (s. D. ) ham-d scores were 21. 5 (2. 7) for no stimulation and 11. 5 (8. 8) for ic/bst stimulation. During the second crossover, ham-d scores were 15. 4 (7. 5) for no stimulation, 7. 6 (3. 8) for ic/bst stimulation and 11. 2 (7. 5) for itp stimulation. The final sample size was too small to statistically analyze this second crossover. At last follow-up, only one patient preferred itp over ic/bst stimulation. Two patients, with a history of suicide attempts before implantation, committed suicide during the follow-up phases of this study. Our data indicate that, in the long term, both itp and ic/bst stimulation may alleviate depressive symptoms in patients suffering from trd. Reported events: pli 10: an unknown number of patients with deep brain stimulation (dbs) leads bilaterally targeting the internal capsule/bed nucleus of the stria terminalis (ic/bst) and the inferior thalamic peduncle (itp) for treatment resistant depression (trd) experienced cognitive/behavioral adverse events that were reportedly stimulation induced. Under stimulation of the ic/bst the authors reported: 1 instance of intrusive thoughts about violent suicide; 1 instance of hearing the voice of their deceased sister; 1 instance of a feeling of derealization; 1 instance of disruption of social skills; 1 instance of increased impulsivity; and 2 instances of concentration difficulties. Under stimulation of the itp the authors reported: 1 instance of obsessive counting; and 1 instance of compulsive stealing. Pli 20: a patient who received 4 dbs leads bilaterally targeting the ic/bst and the itp for trd reportedly had a surgery/device related adverse event relating to their leads being? Conversely labelled? Resulting in the itp being stimulated when they expected the ic/bst to be stimulated. This reportedly led to an additional surgical procedure. Pli 30: a patient with dbs leads bilaterally targeting the ic/bst and the itp for trd experienced damage of the internal capsule electrode. This reportedly led to an additional surgical procedure. Pli 40: a patient with dbs leads bilaterally targeting the ic/bst and the itp for trd experienced an infection around the stereotactic frame attachment site. Pli 50: 2 patients with dbs leads bilaterally targeting the ic/bst and the itp for trd experienced an infection around the implantable neurostimulator (ins). This reportedly led to an additional surgical procedure. Pli 60: a patient with dbs leads bilaterally targeting the ic/bst and the itp for trd experienced sleep apnea that was reportedly induced by stimulation of the itp. Pli 70: a patient with dbs leads bilaterally targeting the ic/bst and the itp for trd experienced urinary retention that was reportedly induced by stimulation of the ic/bst. The authors reported that patients were eventually implanted with model 37612 activa rc's, however the original ins models were not stated. They also reported patients 1-5 received 3387 and patients 6-7 received 3389 model leads. It was not possible to ascertain any additional specific device information from the article or to match the reported event with any previously reported event.
