What risks exist for the patient in undergoing evoked potential studies?

Evoked potential studies are painless, noninvasive, and without any significant risk. Somatosensory EP tests involve very mild electric shocks, usually felt as a tingling.


What is the purpose of evoked potential studies?

Nerves convey information to the body by sending electrical signals down the length of the nerve. These signals can be recorded by wires placed over the nerves on the surface of the skin, in a procedure called an evoked potential (EP) study.

What are auditory evoked potential studies used for?

Auditory evoked potentials are used to diagnose hearing losses. They can distinguish damage to the acoustic nerve (which carries signals from the ear to the brain stem) from damage to the auditory pathways within the brainstem.


What are evoked potential studies?

Evoked potential studies measure the electrical activity in the brain in response to specific stimuli, such as visual or auditory signals. They can provide valuable information about the function of the nervous system, including detecting abnormalities in sensory processing or tracking the progression of diseases like multiple sclerosis. These studies are non-invasive and can help diagnose conditions affecting the brain and nervous system.

What are somatosensory evoked potential studies used for?

Somatosensory evoked potentials record transmission of nerve impulses from the limbs to the brain, and can be used to diagnose nerve damage or degeneration within the spinal cord or nerve roots from multiple sclerosis, trauma, or other.


What is visual evoked potential?

Visual evoked potentials are used to diagnose visual losses due to optic nerve damage, especially from multiple sclerosis. They are also useful to diagnose "hysterical blindness," in which loss of vision is not due to any nerve damage.
