Transcranial magnetic stimulation is a non-invasive stimulation of the cerebral cortex, one of the latest tools that have incorporated the neurosciences, both for purposes of study and research, as therapeutics to treat various illnesses and neuropsychiatric disorders , including depression, anxiety, attention deficit, hyperactivity, autism, abnormal noise or tinnitus in the ear (s), posttraumatic stress, phantom pain in people who have suffered the amputation of limbs or central nervous system injuries, migraine headache, decreased libido, some cases of schizophrenia and epilepsy, and disorders of sleep, obsessive-compulsive, bipolar and uni and, among others.
Also, today is known to have neuroprotective effects that help, at least temporarily, to people affected by neurodegenerative diseases such as multiple sclerosis, Parkinson disease and the Alzheimer’s disease and that a very favourable impact on the modulation of the plasticity brain, which refers to the brain’s capacity to renew or reconnect neural circuits and thus acquire new skills and abilities and to preserve the memory.
Consists of the selective depolarization of these neurons in the neocortex or cerebral cortex, located between 1.5 and 2 cm below the skull, using pulsed magnetic intensities specific, unique or regular repetitive. This practice is called Transcraneana Repetitive Magnetic Stimulation or EMTr (for its initials in English, RTMS).
Depolarization due to the aforementioned principle of electromagnetic induction discovered by M. Faraday.
From the therapeutic perspective, there is already a large number of studies showing that the two aspects of magnetic stimulation Transcraneana, EMT and EMTr are the great virtues of being safe but not harmless, that it is effective but can be scheduled as safe, but several measures taken to ensure such security.
The main contraindications for that treatment has are: women in gestation period, children under six years, and people with pacemakers, electrodes or drug infusion pumps, or with metal plates, wires or screws in the head.
Moreover, some patients undergoing cortical stimulation is experiencing some side effects after application, which can be regarded as minor and transient, such as headache (headache), which can be mitigated with common analgesics. There are also reports that people suffering from epilepsy or take antidepressants epileptogenicos, might get to seizures during treatment with magnetic Transcraneanial stimulation.
