New Delhi, May 19 (ANI): Researchers have shown what happens to the brain when treated for depression known as repetitive transcranial magnetic stimulation (rTMS). The findings of the research were published in the 'American Journal of Psychiatry' by a collaborative effort across the Centre for Brain Health, including DMCBH researchers Dr Sophia Frangou, Dr Rebecca Todd, and Dr Erin MacMillan, as well as members of the UBC MRI Research Centre including Laura Barlow at the University of British Columbia. rTMS is a depression treatment typically used when other approaches -- such as medications -- haven't been effective for a patient. It is estimated that approximately 40 per cent of people with major depression do not respond to antidepressants. During an rTMS session, a device containing an electromagnetic coil is placed against a patient's scalp. The device then painlessly delivers a magnetic pulse that stimulates nerve cells in a region of the brain involved in mood control -- called the dorsolateral prefrontal cortex. Although proven to be effective, the mechanisms behind how rTMS affects the brain have not been well understood. (AK)
