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.

Recent research has unveiled and confirmed the deleterious age-related changes of the immune system which result in diminished ability of older adults to effectively respond to pathogens and infection. This degradation is defined by the term immunosenescence. Immunosenescence can also bring with it reduced vaccine efficacy. In an era where the population of older adults is growing exponentially, it is apparent why such dysfunction is concerning. Adding even more pertinence is the COVID-19 pandemic. Since March of 2020, older adults across the globe have borne witness to the disproportional effects of COVID-19 infection on their mortality rates versus younger adults and children. In order to bring the pandemic to an end, the global population must be inoculated. However, concerns have been raised about the effectiveness of the COVID-19 vaccines on the elderly. This article aims to provide a brief overview of immunosenescence, the COVID-19 pandemic, and what research has shown thus far about vaccine efficacy for older adults. As well, potential methods to combat immunosenescence will be explored.
