What is Transcranial Magnetic Stimulation Therapy (TMS)?

Basically, in TMS, two helical magnetic fields are formed and small electrical activities occur in the region between these magnetic fields. When TMS is applied to predetermine areas related to mental illnesses, it provides clinical improvement by creating electrophysiological changes in these areas. During the application, the coil that forms the magnetic current is placed over the scalp at the point where the target brain region is located. It is applied over the scalp without any intervention to the body. According to the diagnosis of psychiatric disease, the target area and the severity of the magnetic current to be applied are determined.

In What Diseases Is TMS Used?

It is effectively applied by obtaining patient consent in depression and other mood disorders.

Today, TMS is the most common;

In depression,
in periods when drug use is limited such as pregnancy and postpartum period,
in addition to psychopharmacological treatment in treatment-resistant cases,
it is applied before interventional treatments (Electroconvulsive treatment, vagal nerve stimulation, etc.).

TMS also;

Anxiety Disorders
can also be applied in areas such as Auditory Assumptions in Schizophrenia,
Obsessive-Compulsive Disorder (for compulsive behaviours)
Addiction, Tinnitus (for cocaine addiction).

How Long Does TMS Treatment Take?

The effects of TMS vary according to the frequency, intensity, number of trains and pulse pattern of the stimulus instead of the application.

Treatment in TMS is divided into two main components: Acute Treatment and Maintenance Treatment.

Acute treatment lasts 15-30 sessions according to the severity of the disease. It is planned on a daily basis.

Maintenance treatment can change depending on the effect of the disease on the person. While some patients do not need maintenance treatment, some patients are planned to receive maintenance treatments once a week and once a month. In short, maintenance treatment depends entirely on the recurrence and severity of the disease after acute treatment.

A Brief History of TMS

  • The fact that Michael Faraday proved that electricity could be generated from magnetism in 1831 opened a new window in science and the foundations of generators were laid on this principle. tTMS technology is one of the results of this scientific window today.
  • In 1985, Anthony Barker et al. developed the TMS device. With the help of this device, stimulation was carried out in the brain, which could be observed by movement in the hands and feet.
  • The clinical use of tTMS (recurrent transcranial magnetic stimulation) was first approved in Canada in 2002.
  • Recurrent Transcranial Magnetic Warning (tTMS) received FDA approval for the treatment of recurrent Major Depressive Disorder in the psychiatric field in 2008.

As a result;

TMS is a frequently preferred treatment method by clinicians with no side effects and smiling clinical results.
