Immediate Effects of DLPFC tDCS on Attention Bias

NCT05263440 · Status: WITHDRAWN · Phase: NA · Type: INTERVENTIONAL

Last updated 2025-02-05

No results posted yet for this study

Summary

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.

Conditions

Interventions

DEVICE

Transcranial direct current stimulation (tDCS)

Participants will complete a single 30 minutes tDCS session targeting the left DLPFC while sitting in a comfortable position. At the end of the tDCS session possible side effects experienced during the tDCS session will be recorded along with their intensity (rated using the visual analogue scale, 0-10) and duration. The session can be aborted at any time for any reason if the participant wishes.The MINDD STIM tDCS system is composed of a management component, treatment module, single-use sponge patches and supporting patches, a headband to hold in position the sponge patches, and 2 cables. A trained study technician will program the stimulation device through the management component setting to the following stimulation parameters:Stimulation intensity: 2.0 mA or 1.5 mA; Stimulation duration: 30 minutes;Ramp up duration: 30 seconds (beginning of stimulation);Ramp down duration: 30 seconds (end of stimulation)
