In this randomized, single-blinded clinical trial, 58 patients with major depressive disorder were assigned to active and sham tDCS stimulation groups in a 1:1 ratio, and treatment responses were evaluated biweekly over six weeks.

Detailed Description

Patients were randomized to receive either real or sham-tDCS as well as anti-depressant drugs. tDCS was applied over the left (anode) and right (cathode) dorsolateral prefrontal cortex (DLPFC). Patients visited the hospital to get tDCS administrations 5 days a week for 2 weeks. They were evaluated every 2 weeks.

Primary Outcome Measures
NameTimeMethod
Hamilton Depression Scale (HAM-D)Change from Baseline Hamilton Depression Scale at 6 weeks

Hamilton Depression Scale was deployed by a trained psychiatrist at every visit.With a total of 17 questions, the overall score is rated from 0 to 34, and higher total scores indicate more severe depression symptoms

Secondary Outcome Measures
NameTimeMethod
Beck Depression Inventory (BDI)Weeks 0, 2, 4, and 6

The self-rated scale of the Beck Depression Inventory (BDI) was completed by participants. With a total of 21 questions, the score is rated from 0 to 33, and higher total scores indicate more severe depression symptoms.

Montgomery-Asberg Depression Rating ScaleWeeks 0, 2, 4, and 6

Montgomery-Asberg Depression Rating Scale was deployed by a trained psychiatrist at every visit. Higher MADRS score indicates more severe depression, and each item yields a score of 0 to 6. The overall score ranges from 0 to 60.

Beck Anxiety InventoryWeeks 0, 2, 4, and 6

Beck Anxiety Inventory was deployed by a trained psychiatrist at every visit. The BAI contains 21 questions, each answer being scored on a scale value of 0 (not at all) to 3 (severely). Higher total scores indicate more severe anxiety symptoms. The overall score ranges from 0 to 63.
