Following procedures for our validated protocol, participants will receive training on the use of study tDCS device and pre configured laptop computer. The device will be programmed to deliver either active or sham tDCS (all study personnel and participants will be blinded), and operated with unlock codes provided by the study technician daily to release one session. Once trained, and following an initial in-clinic baseline tDCS tolerability test and initial treatment session, participants will use the equipment to complete the remaining sessions from their home using our tele medicine platform. Remote supervision will be provided using HIPAA secure online video conference with the study technician following clearly-defined operational procedures. Participants will be monitored to determine if any predefined "stop" criteria are met using VSee software, a telemedicine software. Additionally, Team Viewer software will allow study technicians to troubleshoot any computer issues, to initiate the video conference on behalf of participants, and to remotely supervise the entire tDCS session.
