Transcranial magnetic stimulation (TMS treatment) is an internationally approved and non-invasive procedure offering hope to people with difficult to treat depression or chronic depression. In Australia, TMS is still considered as a research project.
It is designed to stimulate the prefrontal cortex, specifically the “dorsolateral prefrontal cortex”, known for it connection to the limbic system. The latter is the part of the brain responsible for a number of functions related to feelings, and other symptoms of mood disorder, including depression.
Magnetic fields are used in TMS to stimulate the brain's cortex. It is designed to stimulate the prefrontal cortex which is responsible for a number of functions related to feelings, and other symptoms of mood disorder, including depression. Studies have evaluated the role of TMS in the treatment of depression since the mid-1990s. These studies have clearly shown that TMS is more effective than a placebo type of stimulation, especially in patients who have not responded well to antidepressant medication treatment.
