Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

We intend to investigate whether deep transcranial magnetic stimulation (DTMS), a novel brain stimulation technique, is effective for treating major depression. We hypothesize that 4 weeks of DTMS will be associated with significant improvements in depressive and anxious symptoms without significant side effects.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The aim of this pilot study is to assess, naturalistically, the effectiveness of deep transcranial magnetic stimulation (DTMS) in a sample of subjects with treatment-resistant depression. To do this, enrolled depressed outpatients will be assigned to receive 4 weeks of daily DTMS and will be evaluated at baseline and during week 5. We hypothesize that treatment with DTMS will be associated with significant clinical improvements in depressive and anxious symptoms, and will be well tolerated.

Deep Transcranial Magnetic Stimulation (DTMS)

DTMS will be administered according to the following parameters: 18 Hz in 84 trains of 2 seconds duration, with 20 seconds inter-train interval (3,024 pulses per session) at 120% of the resting motor threshold.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Presence of a current major depressive disorder (according to the DSM-IV-TR) that has not improved after ≥ 1 but ≤ 5 adequate antidepressant trial(s) in the current episode
* Baseline score ≥ 15 on the QIDS-C
* Stable medication regimen (\> 4 weeks)

Exclusion Criteria

* Psychotic features in the current episode
* Lifetime history of psychotic disorders and/or bipolar I or II disorders
* Substance or alcohol abuse/dependence in the past 6 months
* Lifetime history of a major neurological disease (e.g., Parkinson's, stroke)
* Uncontrolled medical disease (e.g., cardiovascular, renal)
* Pregnancy and/or lactation
* Presence of a specific contraindication for DTMS (e.g., personal history of epilepsy, metallic head implant)
* Hearing loss
* Personal history of abnormal brain MRI findings
