Heart Rate Variability (HRV)-Guided Transcranial Direct Current Stimulation (tDCS)
Sponsor: NYU Langone Health
Summary
This technology development project will be informed and guided by initial data collection of human subject data. For this purpose, the investigators will recruit n=100 people with mild to moderate depression in a double-blinded, parallel-arm, sham-controlled data collection period administered at home and using the investigator's remotely supervised (RS) tDCS protocol. Enrolled participants will complete 10 days of 30-minute tDCS (2.0, DLPFC left anodal) using the RS-tDCS protocol. During each daily session, standard HR and impedance-based HR (i-HR), obtained from the tDCS headset, will be collected to identify a possible marker of response to tDCS in depression. Participants will be randomized 2:1 to active vs. sham tDCS.

Interventions
Active Transcranial Direct Current Stimulation (tDCS)
tDCS will be delivered using the 1x1 Mini CT tDCS device. For active tDCS, the device is programmed to ramp up to 2.0 mA (for 30 seconds), provide constant current throughout the session (29 minutes), and then ramp down (for 30 seconds) at the end. Participants will receive 10 sessions of tDCS over the course of this study on weekdays (M-F).
Sham Transcranial Direct Current Stimulation (tDCS)
Sham tDCS will be delivered using the 1x1 Mini CT tDCS device. For sham tDCS, the device is programmed to ramp up to 2.0 mA (for 30 seconds) followed by a ramp down (30 seconds), with no current delivery for 28 minutes, and then ramp up (for 30 seconds) and down (for 30 seconds) at the end. Participants will receive 10 sessions of sham tDCS over the course of this study on weekdays (M-F).
