During a session, a small electromagnetic coil is positioned against your scalp. The coil delivers short, repetitive pulses that pass painlessly through the skull to stimulate the dorsolateral prefrontal cortex, the area of the brain responsible for mood regulation. In depression, this region is consistently shown to be underactive on functional brain imaging.
By restoring activity in that circuit over the course of treatment, TMS can shift the underlying neurobiology of depression. Improvement is gradual. Most patients notice changes in sleep, energy, or motivation within the first two to four weeks. A standard course runs 36 sessions, after which many patients require no maintenance.
At Better Balance Psychiatry, treatment is delivered using MagStim Horizon technology and supervised by board-certified psychiatrists in both our St. George and Cedar City offices.
