This prospective pilot study will recruit 25 female participants, ages 18-45 (inclusive), with mild to severe depression (based on BDI-II score range 14-19 for mild and 29-63 for severe) to determine if a single-session of tDCS can alter negative attention bias. The primary objective is to study if single-session tDCS will affect attention bias in depression and is not meant to treat depression. Subjects may or may not be receiving treatment for mild-severe depression.
This research is being done to test if the investigators can modify or reduce negative attention bias in depression following a single session of transcranial direct current stimulation (tDCS) over the left anodal dorsolateral prefrontal cortex (DLPFC) in patients with mild to severe depression. The study will consist of a single-session tDCS session administered onsite at the Johns Hopkins University (JHU). After the consent process, participants will complete the study (approximately one hour in duration) with the guidance of a research associate.
