What is TMS?
Transcranial magnetic stimulation or TMS is a non-invasive medical treatment that uses a magnetic field to stimulate nerve cells in the brain mainly for depression. However, recent studies show that TMS can cure a variety of mental disorders including addiction.
How does it work?
In this procedure, the electromagnetic coil is placed on the scalp of the patient near the forehead. The electromagnet delivers a magnetic pulse to stimulate nerve cells in the brain that involves regularization of the mood control and depression. TMS activates this region of the brain to reduce the activity associated with depression. It sends stimulation effects in the part of the brain linked with treating depression and mood improvement.
Treatment of depression is through repetitive magnetic pulse called r TMS or TMS. Depression is well treatable but a lot of people failed to achieve success using conventional medical treatments and therapies. TMS, on the other hand, is an effective alternative treatment for depression with fewer or no relapse at all. Unlike the other procedures including nerve stimulation or deep brain stimulation, TMS is a non-invasive and non-systemic treatment. As a non-systemic procedure, it does not cause any side effects of seizures or any sedation with anesthesia.
Patients with melancholic depression can also benefit from TMS. There are several studies suggesting on how to use TMS on specific disorders. Multicenter studies on efficacy for 6 weeks will test whether a longer period of stimulation is more effective in a controlled setting. While another research shows that a right-sided stimulation is more effective.
What to expect in a TMS session?
This medical procedure uses an electromagnetic coil extends with a high-intensity current that turned on and off in the coil through the discharge of a capacitor. This is a time-varying a magnetic field which lasts for about 100 – 200 microseconds. The strength is about 1.5 to 2 Tesla at the surface of the coil.
Healthcare professional conducts TMS as an outpatient basis in a clinic and it requires a series of treatment sessions to become more effective and preferably within five times a week for about four to six weeks. The attending doctor will conduct the procedure in the best place. Pacing the magnet on the head and best dose of magnetic energy will be given. Upon the first session of appointment, the patient will be placed in a treatment area where there is a wearing of earplugs, an electronic coil will also be placed in the forehead and switches off and repeated to produce stimulating pulses.
The tapping of the sounds will last in a few seconds and then pause for a while, the feeling sensation on the forehead called mapping. Doctors will then determine the right amount of magnetic energy that patients needed.
During the actual treatment, once a coil is placed on the forehead and dose is identified, now ready to start the procedure. Once settled in a comfortable chair wearing earplugs and the magnetic coil placed, health care professionals will turn the machine on. The patients will then hear a clicking sound or feel a light tapping on their forehead. The procedure will last about 40 minutes, patients will remain wide awake and alert the entire session. Patients may feel some mild discomfort during the treatment within the first week but will ultimately subside afterward.
The preparation of TMS should always be observed before applying to patients. TMS treatment is not for everyone, although relatively safe, there are pre-medical evaluation and tests. These include the following:
- Physical examination and doing laboratory tests or any other tests required to make sure that the r TMS is safe and in normal,
- have a psychiatric assessment to evaluate the mood of depression,
- any metal or implanted medical device in the body in some patients or people with metal implant device can have the procedure and due to strong magnetic field
Furthermore, it is recommended for the following persons who have aneurysm clip or coil, stents, implanted stimulators, implanted vagus nerve or deep brain stimulators, electrodes for brain monitoring, implanted electrode device such as a pacemaker, medication pump, and bullet fragments to undergo TMS.
After TMS treatment
After treatment, normal activities or daily works are normal once the patient was treated, such as driving and working in the offices and others. May different ways to perform its techniques may vary according to the studies for more effectiveness.
TMS effectiveness in depressed patients takes about several weeks of treatment depending upon the cooperation of each patient. Symptoms will drastically improve during and even after treatments. There are no significant signs of relapse. When undergoing the procedure, it involves continuing treatment until patients are symptom-free with the hope that will prevent relapses.
Depression improves clinically proven with TMS and if there is an episode or return of symptom it can be repeated again called re-induction. All the procedures and management will become helpful for the intervention to prevent and detect the depression or any other mood disorders.
