What Is Transcranial Magnetic Stimulation? :
Transcranial magnetic stimulation is normally abbreviated to TMS. Essentially, this treatment works by delivering short pulses of magnetic energy (which are generated by a hand held device that contains an electro-magnetic coil) to specific brain regions. It is a non-physically invasive therapy and the smallish, relatively simple device is merely guided over the relevant areas of the patient’s head by the doctor.
Research has already shown that the treatment can significantly reduce depressive symptoms in patients and early indicators are that it may also be of benefit to individuals suffering from the effects of trauma.
In order to help you visualize the simplicity of the procedure, imagine a hair-dryer being moved over the head – the only difference is that, rather than warm air being delivered,essentially painless, magnetic pulses are delivered instead.
HOW DOES TMS WORK?
I have already stated that the procedure is essentially painless (although some patients report that it has induced in them a headache) so the magnetic pulses are delivered whilst the patient is fully conscious. The procedure generally takes about twenty minutes. The magnetic pulses work by altering the way in which the brain cells communicate with each other (or, to put it more technically, the electrical firing between the brain’s neurons is altered) in the specific brain regions at which the treatment is directed. Research into the treatment has so far suggested that it may:
POSSIBLE SIDE EFFECTS OF TMS :
Unfortunately, TMS cannot be administered to those individuals who have been fitted with a pacemaker (or, for that matter, have had any other metal implanted in their body). Also, it cannot be administered to those who suffer from epilepsy in most cases.
In rare cases, TMS may induce seizures or manic episodes.
Anyone considering the treatment should discuss it with their doctor.
