An evoked potential study is an auxiliary examination method with an important place in the complex diagnostic process and evaluation of central nervous system impairment, particularly in the assesment of demyelinating disorders. This is a highly sensitive method, which is capable to detect subclinical changes of nerve tract conduction. Despite its low specificity it remains commonly used as it is widely available, easily performed and reproducible, and repeatable. Evoked potentials are effective not only in diagnostics but also in monitoring motor, sensitive or cognitive deficit progression, and in assessing the treatment efficacy.
