Evoked Potentials in Istanbul – New City Clinic

Evoked Potentials in Istanbul: overview

Evoked potential tests measure the brain’s electrical response to harmless stimuli given to the eyes, ears or nerves in the arms and legs. Visual evoked potentials (VEP) assess the visual pathway, brainstem auditory evoked responses (BAEP) the hearing pathway, and somatosensory evoked potentials (SEP) the sensory pathways. In multiple sclerosis (MS), optic neuritis and some other nervous system conditions, they add information to MRI findings. The tests are painless and done as an outpatient.

Who is it for?

Evoked potentials suit people being assessed for multiple sclerosis, optic neuritis or unexplained visual, hearing or sensory symptoms, together with an MRI.

Types of evoked potential test

Depending on the question, one or more tests are performed:

  • VEP: you look at a changing pattern on a screen
  • BAEP: clicks are played through headphones
  • SEP: small pulses are given to nerves at the wrist or ankle

Recovery

Most consultations and tests are outpatient, so you can return to daily life the same day. A sleep study and long video-EEG recordings involve a night in hospital.

What you should know

  • Most tests are painless; needle EMG can cause brief mild discomfort
  • You may feel tired after a sleep-deprived EEG; do not drive that day
  • In an emergency such as sudden weakness, slurred speech or a seizure, go to your nearest emergency department

Every medical procedure carries risk. Your physician will explain the risks specific to you during your examination.

Frequently asked questions

What is evoked potentials?

Evoked potential tests measure the brain’s electrical response to harmless stimuli given to the eyes, ears or nerves in the arms and legs. Visual evoked potentials (VEP) assess the visual pathway, brainstem auditory evoked responses (BAEP) the hearing pathway, and somatosensory evoked potentials (SEP) the sensory pathways. In multiple sclerosis (MS), optic neuritis and some other nervous system conditions, they add information to MRI findings. The tests are painless and done as an outpatient.

How many days do I need for the consultation and tests?

Most consultations and tests are completed in 1–3 days. A sleep study takes one night, and video-EEG can take several hours or a few days; the exact length is given to you in writing.

For an EEG, your hair should be clean and free of oil; before an EMG, do not apply cream to your arms and legs. Do not stop your medicines – bring a list with you. Any special preparation is sent to you in writing beforehand.

Who reviews the results?

Recordings are made by an electroneurophysiology technician; they are reviewed and reported by a neurologist.
