Transcranial Magnetic Stimulation, or TMS, is a revolutionary new procedure that has taken on the field of depression treatment by storm. It has produced many amazing results in cases where traditional forms of treatment such as medication and therapy have not helped. So what exactly is transmagnetic stimulation and TMS therapy, and what does it do? Read on to learn more about the procedures and effects of TMS therapy as well as how it works.

What Can I Expect During TMS Therapy?
So what exactly can the patient expect during the transcranial magnetic stimulation procedure? The doctor usually performs this procedure while the patient is awake and seated in a chair. Near the patient’s left prefrontal cortex, front side of the scalp, or any area where a lack of functional and metabolic activity is found in the depressed patient, a device with an electromagnet coil is placed. For about 40 minutes the device is held in place while a steady electric current is passed through this part of the brain, causing nerve cells, or neurons, in the brain to send electrical impulses. A chemical reaction is then triggered by these impulses, which over time helps to lift the patient’s mood. Typically 30 sessions of TMS therapy is recommended, generally given five times per week for four to six weeks. Since this type of pulse generally only reaches about 2 inches into the brain, the doctor can target the specific portion of the brain they want to treat. Side effects then have a much lesser chance for occuring (as it tends to with other procedures) thanks to the precision that is achieved with TMS.
Types of Transcranial Stimulation
There are a few different types of transcranial magnetic stimulation treatment that are available to our patients as part of depressive treatment. The first type is Repetitive Transcranial Magnetic Stimulation (rTMS), which uses more intense electric pulses. rTMS is generally used for patients who have unipolar depression. During rTMS an electromagnetic coil is held against the patient’s left side of the scalp and short pulses of electromagnetic waves are conducted through the coil. The repeating magnetic pulses cause small electrical currents that stimulate nerve cells in the targeted region of the brain. Each rTMS session generally lasts 30 to 60 minutes, does not require sedation or anesthesia, and the strength of the currents is similar to those in an MRI scan. The other type of TMS therapy is Deep transcranial magnetic stimulation, or dTMS, and is a relatively novel method of stimulating deeper, larger brain regions. Specialized coils called H coils are utilized in this procedure, and reach about 2 inches beneath the surface of the skull. These coils are designed to target different brain areas. A person wears a cushioned helmet during a dTMS session, which generates brief magnetic fields, similar to those in MRI scans.
