The COVID-19 pandemic has illuminated a need for accessible, home-based therapies for mental health. In an era of social distancing, lockdowns, and declining global mental health, one promising candidate is transcranial Direct Current Stimulation (tDCS). tDCS is a non-invasive, portable, targeted brain stimulation technique that uses electrical currents to modulate cortical excitability. It has been heavily explored as a treatment for major depressive disorder (MDD) and other mental health issues in recent years. However, before such a treatment may become widespread, certain research questions must be addressed, and safety outcomes must be thoroughly evaluated. This article aims to provide a brief overview of tDCS, the COVID-19 pandemic’s impact on mental health, and tDCS’ potential to be used in such a situation. The article also explores some of the drawbacks and challenges that lie in the way of tDCS being normalized as a mental health therapeutic.
