What is transcranial magnetic stimulation (tms) or brain stimulation (tmu) therapy?

The brain is an organ that works with electrical impulses emitted by neurons. In some cases or diseases, there are disturbances in electrical stimulation in different parts of the brain. Transcranial magnetic stimulation (TMS) or stimulation (TMS) treats these disorders externally by intervening. What is the mechanism of action of TMS, how is it applied? TMS is applied 2-3 cm above the skull with the help of a coil. With the magnetic field effect it creates, it activates the electric current in the cerebral cortex and thus depolarizes the neurons. TMS has different effects when applied at different frequencies. High frequency TMS causes excitation (excitation) and low frequency TMS causes inhibition (slowing) in the area where it is applied. In repetitive TMS, magnetic pulses come in a rapid series. In different diseases, the place, intensity and time interval of stimulation are adjusted. Where is TMS used? TMS can be used in many different psychiatric and neurological diseases. Studies conducted on patients with major depression have shown the effectiveness of TMS studies applied at high frequency to the left prefrontal cortex in the treatment of depression. TMS has FDA (American Food and Drug Administration) approval for the treatment of depression. It also has FDA approval as an effective treatment method in drug-resistant migraine diseases. Apart from depression, it is also used effectively in many psychiatric disorders.

In addition to anxiety disorders, it is very effective in hyperactivity and attention disorder. It can be used safely in childhood due to the absence of side effects. It has been found to be very effective in neurological diseases such as Parkinson’s, Alzheimer’s, essential tremor, aphasia and tinnitus and is widely used. It has also been reported to be very effective in reducing strength losses, speech delays and neuropathic pain after stroke and bleeding.


Depression can be seen in 15% of mothers during pregnancy and in the early postpartum period. Treatment becomes difficult, especially since the drugs given for depression during pregnancy are harmful to the baby. In addition to motivational interviews to be determined according to the severity of the mother’s symptoms, cognitive behavioral studies, TMS applied as a somatic treatment can help patients during pregnancy and puerperium.


During TMS application, patients do not feel any pain. Current safety protocols adjust the amount of stimulation relative to an individual’s motor threshold.
