Evoked Potential Tests

Within the most innovative and cutting-edge techniques that exist in Spain, our hospitals use the most advanced diagnostic tools. This is one of the most standardised techniques in Europe and the United States to determine the response to hundreds of stimuli.

Consider coming to Spain when there are any of the following conditions: Multiple sclerosis, hearing loss, optic neuritis or head trauma.

Treatment characteristics

Evoked potentials are diagnostic tests dedicated to study the electrical activity of the neurons to detect if there is any dysfunction in the nervous system.

Auditory – checks the correct response of the nervous system to auditory impulses or stimuli.

Somatosensory – checks the correct response of the nervous system to touch impulses or stimuli.

Visual – checks the correct response of the nervous system to visual impulses or stimuli

For any of the three types, the technicians connect a series of electrodes to monitor your “reactions” to the stimuli. They usually last between 30 and 40 minutes.

For auditory test, you will need to wear headphones that emit different types of sounds.

For visual test, you will need to look at a surface where the technician project lights of different intensities and flashes.

For somatosensory test, the technician will place electrodes on your feet or hands or near the areas to be studied. The electricity will pass through the electrodes and stimulate the nerves.

The tests are done to diagnose in order to treat pathologies associated with the nervous system such as:

  • Optic neuritis (inflammation of the optic nerve that causes loss of vision).
  • Multiple Sclerosis.
  • Hypoacusis (hearing loss).
  • Head injuries.
  • Spinal cord or brain stem injuries

You only need to stay in Spain long enough to have the test done and obtain the results to start the treatment. No recovery is required
