MOTOR AND SOMATOSENSORIC EVOKED-POTENTIAL S IN THE DIAGNOSTIC OF IMMUNONEUROPATHIES

Proximal demyelinisation is a common pathophysiological feature in acu te inflammatory demyelinating polyneuritis, chronic inflammatory demye linating polyneuropathy and in multifocal motoric neuropathy. The diag nosis of this peripheral nerve disorder with classical electroneurogra phy is not always successful. We demonstrate the data of motor evoked potentials and somatosensoric evoked potentials as a diagnostic tool i n these immunneuropathies. Evoked potentials are more reliable than cl assical electroneurography. Motor evoked potentials are more sensitive than SEP. A proof of proximal demyelinisation is earlier possible wit h evoked potentials. We recommend the use of this diagnostic tool in p olyneuropathy.
