Evoked Potential Testing
The doctors supported by Northern Neuroscience provide advanced Evoked Potential (EP) testing to assess the function of the nervous system. The expert doctors we support use these tests to diagnose and monitor a variety of neurological conditions, ensuring accurate and effective patient care.
What is Evoked Potential Testing?
Evoked Potential (EP) testing measures the electrical activity in the brain in response to specific sensory stimuli. These tests help evaluate the pathways of the visual, auditory, and sensory systems, providing valuable information about the functioning of the nervous system.
Types of Evoked Potential Tests
The doctors we support We offer several types of EP tests, each designed to assess different sensory pathways:
- Visual Evoked Potentials (VEP): Measures the response of the visual system to visual stimuli, commonly used to diagnose optic neuritis and other visual pathway disorders.
- Brainstem Auditory Evoked Potentials (BAEP): Assesses the auditory pathways from the ears to the brainstem, useful in diagnosing hearing loss and brainstem disorders.
- Somatosensory Evoked Potentials (SSEP): Evaluates the response of the sensory pathways to stimuli, aiding in the diagnosis of spinal cord and peripheral nerve disorders.
Who Might Need Evoked Potential Testing?
EP testing is recommended for individuals experiencing:
- Visual disturbances or loss of vision
- Hearing impairments or unexplained hearing loss
- Symptoms suggesting multiple sclerosis or other demyelinating diseases
- Unexplained sensory deficits or neuropathy
What to Expect During the Tests with your doctor
- Preparation:
- No special preparation is usually required
- Continue taking your usual medications unless instructed otherwise
- Ensure you are well-rested before the test
- During the Tests:
- You will be seated or lying down comfortably
- Electrodes will be placed on your scalp and other relevant areas
- Specific sensory stimuli will be presented, such as visual patterns, auditory clicks, or small electrical pulses to the skin
- The test typically takes 30-60 minutes, depending on the type and number of EP tests being performed
- After the Tests:
- Once the test is complete, the electrodes will be removed, and you can resume normal activities
- Your specialist will analyse the recordings and provide a detailed report to your referring doctor
- The results will help guide further diagnostic and treatment decisions
