The process involves placing an electromagnetic coil on the patient’s forehead and stimulating nerve cells with electric currents that can help to alter moods and alleviate depression. Unlike other forms of brain stimulation, TMS does not involve the insertion of electrodes or any other invasive procedure, and is therefore more comfortable for the patient. In contrast to other treatments that utilise electro-stimulation, it does not have a potential to cause seizures and can be carried out without the patient being chemically sedated.
The sessions normally last up to six weeks and can cause some mild effects that tend to improve after the first 2 weeks or so. These side effects include: itching of the forehead, headaches, muscular tingling and mild dizziness. Occasionally, the patient can experience more serious side-effects such as seizures, a sensation of mania and hearing loss – although these occurrences are very rare. The sessions generally last for around 40 minutes and can be performed in a doctor’s surgery, so the patient does not have to be hospitalised.
As with all procedures of this nature, before starting TMS treatment it is vital for patients to receive a medical assessment, as some health conditions can inhibit the practice being administered safely and effectively. Additionally, TMS can present certain risks if the patient is pregnant, or has any medical devices such as a pacemaker inserted into their body.
Whilst, it’s a relatively new treatment, it is gaining popularity within the mental health community, and can be effective when other treatment approaches have failed.
