Transcranial magnetic stimulation (TMS) is a non-invasive therapeutic technique used to stimulate regions of the brain using magnetic pulses. Repeated TMS delivers sequences of pulses for multiple days in a row and is an approved treatment for several psychiatric conditions. Deep TMS (dTMS) is a new technique that uses modified magnetic Hesed coils (H-coils) to stimulate deeper regions of the brain and has been FDA- and Health Canada-approved for major depressive disorder (MDD), obsessive-compulsive disorder, smoking cessation, and anxious-depression in adults. For older adults (60+), traditional rTMS has also shown efficacy for MDD (60+) and one RCT has found benefit for the H1 dTMS coil, but no trials have examined the H4 and H7 coils in this population. This innovative pilot study will explore dTMS feasibility and tolerability (i.e., side effects, impacts on mental health and cognition) of these two dTMS coils (H4, targeting insula and H7, targeting anterior cingulate cortex) in older adults with depression. The pilot will provide critical preliminary data for a future trial comparing these novel interventions to the H1-coil and a sham stimulation control. There is sparse literature examining the effects of dTMS on cognition, as measured by neuropsychological testing, and brain activity, as measured by electroencephalogram (EEG), while comparing different dTMS H-coils. Therefore, a second feature of the design includes assessing both domains over the course of treatment. The results will lay the foundation for a future randomized controlled trial examining the efficacy and mechanisms of one or both of these novel forms of neurostimulation for MDD in older adults.
