Evoked potentials for evaluation of multiple sclerosis

The role of evoked potentials (EP) in the assessment of multiple sclerosis (MS) has changed over the last decade. This is largely due to progress in imaging techniques. But while MRI has a greater diagnostic sensitivity, EP remain a useful diagnostic tool in many clinical situations. Moreover, recent studies demonstrate the utility of EP for monitoring and predicting the course of the disease in patient groups, although not yet in individuals. For these purposes, EP show better results than conventional MRI. In the near future, new developments in electrophysiology, immunology and imaging may allow to differentiate between different subtypes of MS early in the course, and consequently to tailor therapeutic measures more precisely to the individual patients.
