Transcranial Direct Current Stimulation (tDCS) in Young Individuals with Major Depressive Disorder: a Literature Review and Feasibility Study

NCT06518642 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 8

Last updated 2024-11-27

No results posted yet for this study

Summary

Objectives: (1) To assess the therapeutic effects of tDCS on improving depressive symptoms in young individuals with Major Depressive Disorder (MDD), relative to sham stimulation ; and (2) to evaluate the tolerability, and feasibility of tDCS in young individuals with Major Depressive Disorder, to explore the feasibility for a scale-up study.

Hypothesis: 1) we hypothesize the tDCS stimulation of the dorsolateral prefrontal cortex (dLPFC) will reduce symptoms of depression more than sham stimulation, demonstrated by significant difference in change of Hamilton Depression Rating Scale (HDRS) and 2) tDCS active stimulation of the dLPFC will be tolerable and feasible among patients with MDD, as demonstrated by minimal adverse effects measured in the Adverse Events Questionnaire, adherence (with reasons of drop out), their motivation and enjoyment to participate in the study .

DEVICE

Sooma tDCS portable device - active stimulation

Treatment followed common tDCS protocol upon considering safety and tolerability, comprising five consecutive sessions in five days of 30-minute 2 mA tDCS. We utilized the Soterix Medical tDCS device (Soterix Medical, New York, NY, USA, Model 1x1 tDCS-CT) in the research lab and the Sooma Oy device (Sooma Depression Therapy Comfort, Helsinki, Finland) for patient self-administration.Sooma provided two of their portable tDCS devices for a brief period, including one customized sham device.Due to the limited availability of the Sooma devices, participants were randomly allocated to either the Sooma or. Due to the limited availability of the Sooma devices, participants were randomly allocated to either the Sooma or the Soterix device based on availability during their initial session. A current of 2 mA was applied with the anode positioned left DLPFC, corresponding to area F3 in the international 10-20 system. The cathode (reference electrode) was applied at the right dPLFC, F4.

DEVICE

Sooma tDCS portable device - sham stimulation

Sooma provided two of their portable tDCS devices for a brief period, including one customized sham device for effective blinding, distinguishable only by serial number and managed by an external data manager following the randomization sequence.To ensure blinding to the participant and their caregiver, at the beginning of the stimulation sessions, participants receiving both the active and sham stimulation would experience a ramp-up in current from 0 to 2 mA, and then the current would ramp down to 0 mA for participants receiving sham stimulation. Participants were told that they may experience sensations such as tingling, headache, or mild burning during the first 30-60 seconds of the stimulation session but that they may subside afterwards as they got used to it. In other words, participants would not be able to tell if diminishing of side effects were due to habituation (active tDCS) or ramping down of current (sham tDCS).
