Study design
This study is a factorial randomized, placebo-control trial, including 2 groups: 'sertraline only' (sertraline + sham tDCS), and 'combined treatment' (sertraline + active tDCS). It is planned to recruit 20 subjects for each group, which results in all together 40 participants. Patients will take 12 tDCS sessions (30min for each session): first 10 consecutive sessions for two weeks (Monday to Friday), and then 2 follow-up sessions scheduled 2 and 4 weeks after the consecutive treatment. Both pharmacological and tDCS intervention will be started simultaneously on the first day of the treatment.
