Deep TMS in a resistant major depressive disorder: a brief report

Background:

Repetitive transcranial magnetic stimulation (rTMS) has proven effective. Recently, a greater intracranial penetration coil has been developed.

Objective:

The studytested the efficacy of the coil in the treatment of resistant major depression.

Methods:

The studysample included seven patients suffering from major depression who were treated using Brainsway’s H1-coil connected to a Magstim rapid 2 stimulator. Deep TMS treatment was given to each patient in five sessions per week over a period of 4 weeks.Patients were treated with 120% intensity of the motor threshold and a frequency of 20 HZ with a total of 1,680 pulses per session.

Results:

A significant improvement in HDRS scores was found when high, but not low, stimulation intensity was used. Several cognitive improvements were evident, and no treatment-related serious adverse events were observed.

Conclusions:

This study provides additional evidence for the feasibility and safety of the twoH-coil designs (H1/H2). The H-coils offer a safe new tool with potential for both research and clinical applications for psychiatric and neurologicaldisorders associated with dysfunctions of deep brain regions.
