TMS utilizes a device that generates a magnetic field which passes through the scalp and skull to reach targeted brain regions. The magnetic field is created by passing an electrical current through a coil, which generates a changing magnetic field to modulate the impacted brain region.

The specific brain regions targeted are determined based on the individual’s symptoms and diagnosis. The most common target area for depression is the left prefrontal cortex, associated with mood regulation.

The TMS device delivers repetitive magnetic pulses to a targeted brain area. These pulses are administered in short bursts or trains, and treatment sessions usually last between 3 to 30 minutes.

The magnetic pulses induce electrical currents in the brain, which can modulate neuronal activity. The exact mechanisms are not fully understood, but it is believed that TMS helps regulate the activity of specific brain circuits associated with mental health conditions.

TMS is thought to influence neuroplasticity, the brain’s ability to reorganize and form new connections. It may also impact the release of neurotransmitters, such as serotonin, dopamine, and norepinephrine, which play a role in brain regulation.

Treatment of depression using TMS may require multiple sessions within a day or daily treatment for several weeks. Generally, clients can receive daily treatments for approximately 20 to 30 sessions over several weeks. Alternatively, accelerated protocols can provide 6-10 treatments daily for five consecutive days. The treatment plan may differ depending on the individual’s response, requirements, and the recommendations of the treatment team.
