Therapeutic repetitive transcranial magnetic stimulation (rTMS) is a non-invasive procedure designed to treat various mental health disorders by stimulating specific areas of the brain. This treatment is particularly focused on addressing conditions where certain brain regions exhibit abnormal activity levels. For example, individuals suffering from depression often have reduced activity in the left prefrontal cortex, which rTMS aims to target and stimulate. The procedure involves the application of a magnetic field generated by an electrical current, which is delivered through a wire held against the scalp. This magnetic field penetrates the skin and skull, inducing a current in the brain that activates nearby nerve cells, similar to how direct electrical stimulation would work on the cortical surface. The rTMS treatment is tailored to the individual’s specific needs, including the targeted brain area, treatment duration, and application method, ensuring the most effective therapeutic outcome. The therapy is known to influence the brain's biochemistry, neuronal firing patterns, and neurotransmitter levels, such as serotonin, which are crucial in managing mental health disorders. The precision of rTMS can be enhanced through the use of stereotactic MRI reference, allowing for accurate targeting within a few millimeters. Each session of rTMS treatment is carefully delivered and managed, contributing to a comprehensive approach to mental health care.
