List of investigations

Evoked Potentials

Evoked potentials are neurological investigations that assess how the nervous system responds to various stimuli. At CardioPrima, we perform:

• Auditory evoked potentials — to evaluate the response of auditory neural pathways to sound stimuli;
• Visual evoked potentials — to assess the response of the optic nerve and visual pathways to light stimuli.

Recommendations before the investigation

• Wash your hair before the appointment; hair should be clean and dry, without gel, hairspray, or oils.
• Have a good night’s rest before the test — sleep deprivation may affect the results.
• Wear comfortable clothing and avoid large or metal accessories around the head area.
• Bring with you:
  • a complete list of current medications,
  • recent neurological investigations (EEG, imaging studies, audiograms, ophthalmologic reports, if available),
  • the referral from your treating physician.
• For visual evoked potentials, if you wear glasses or contact lenses, bring them with you.
• For auditory evoked potentials, ensure earwax is removed if necessary.

What happens during the investigation

• Electrodes are placed on the scalp to record brain responses to stimuli.
• For visual evoked potentials, you will watch light patterns on a screen.
• For auditory evoked potentials, you will hear sounds or clicks through special headphones.
• The procedure is painless and involves no risks.

After the investigation

• You may immediately resume your daily activities.
• The results will be interpreted by a neurologist, who will provide conclusions and recommendations.
