Levkovitz, Y., Sheer, A., Harel, E. V., Katz, L. N., Most, D., Zangen, A., & Isserles, M. (2011). Brain stimulation, 4(4), 266-274.
This study examined the effect of the BrainsWay® Deep TMS (Transcranial Magnetic Stimulation) H-coil stimulation on depressed patients, and evaluated separately the effect on depressive symptoms and on one of depression’s core symptoms – apathy. In the study, antidepressant medication treatment was ceased, and Deep Transcranial Magnetic stimulation was given 5 days a week, over 4 weeks. The study demonstrated that brain stimulation using the Deep TMS H-coil significantly alleviates depressive symptoms including apathy, but only if pre-treatment apathy was not very severe.
