Home-based Transcranial Direct Current Stimulation (tDCS) for Treatment of Attention-deficit/Hyperactivity Disorder (ADHD)
Massachusetts General Hospital
Summary
The investigators are investigating whether home-based tDCS over the course of four weeks can improve ADHD symptom severity and improve dysexecutive functioning (cognitive control). Further, the investigators are investigating whether there is a dose-dependent response to tDCS.
Description
This mechanistic clinical trial will be the first of its kind to assess the clinical and cognitive efficacy of tDCS, and its relationship to physiological target engagement. It will also provide critical knowledge about tDCS dosing in a therapeutic context (i.e. 30 days of daily tDCS). Last, it will assess the feasibility and acceptability of home-based neuromodulation therapies for ADHD, reducing the most significant obstacle for the implementation of devices therapies (i.e. daily visits to the hospital for several weeks) and facilitating access to advanced therapeutics to a large population…

Interventions
- Device2 mA transcranial direct current stimulation (tDCS)
tDCS is a non-invasive neuromodulatory technique that has previously demonstrated the ability to transiently modulate cognitive domains in both healthy and psychiatric populations. In the 2mA condition, the investigators will assist the administration of a 2mA current stimulation from the device.
- Device1 mA transcranial direct current stimulation (tDCS)
tDCS is a non-invasive neuromodulatory technique that has previously demonstrated the ability to transiently modulate cognitive domains in both healthy and psychiatric populations. In the 1mA condition, the investigators will assist the administration of a 1mA current stimulation from the device.
- DeviceSham transcranial direct current stimulation (tDCS)
tDCS is a non-invasive neuromodulatory technique that has previously demonstrated the ability to transiently modulate cognitive domains in both healthy and psychiatric populations. In the sham condition, the investigators will assist the administration of a sham stimulation from the device.
