It is a non-invasive procedure that consists of stimulating the cerebral cortex in order to treat various diseases and neuropsychiatric disorders. The process involves placing an electromagnetic coil on the scalp and subsequently emitting painless magnetic pulses to stimulate neurons in brain regions that control mood.

Here are some disorders that can be treated with repetitive transcranial magnetic stimulation:

Postpartum depression.
Neuropathic pain.
Anorexia.
Anxiety.
Epilepsy.
Schizophrenia.
Fibromyalgia
Rehabilitation after suffering a stroke.
Tinnitus.
Bipolarity.
Depression and post-traumatic stress.
Borderline personality and obsessive-compulsive disorder.

Once your physical condition has been assessed, your doctor will analyze your clinical history and request laboratory tests to define if you are a candidate to receive this treatment, whose sessions last approximately 25 minutes for a period of three to four weeks, depending on the pathology. At the end of each session, you will be able to perform your usual activities immediately.

It is a safe procedure, but in some cases it can cause some mild to moderate side effects, such as:

Headache and lightheadedness.
Seizures.
Burning and discomfort in the stimulated area.
Tingling and slight spasms.

At the Neurophysiology Clinic we are prepared to offer you the most advanced neurophysiological tests to diagnose the various pathologies that affect your nervous system, which represent a quantitative, reproducible, and generally non-invasive measure that enriches the neurological examination, providing an interaction platform and support in the diagnosis and treatment of neurologically affected patients.

The tests we perform include all the tools of a comprehensive neurophysiology service:

Electroencephalogram.
Electromyography.
Evoked potentials.
Outpatient polysomnography.
Hospital polysomnography.
Transcranial doppler.
Neuro-otology tests.
Otoacoustic emissions.
Intraoperative monitoring.
Magnetic stimulation.
