Cabello-Rangel et al., 2023. Journal of Global Health Neurology and Psychiatry

Depressive symptoms reduced by more than 30% in 70% of the patients after 3 weeks of tDCS treatment.
The reduction of symptoms was maintained ´at one month after treatment conclusion.
Using Sooma tDCS, 30-minute sessions were conducted for 5 consecutive days a week, for a total of 15 sessions.
A 2mA stimulus was applied with the anode over the left lateral prefrontal cortex and the cathode over the right supraorbital region.
tDCS was found to be effective as an adjunct to pharmacological treatment.
