title: [Topodiagnostic ERA results at a female patient with multiple sclerosis in the brainstem (author's transl)].
abstract: At a female patient suffering from multiple sclerosis with demyelinisation mainly in the pontine and mesencephalic tegmentum, the five early potentials consisting of the compound action potential of the acoustic nerve (Pot. I) and the four brainstem potentials (Pot. II-V) as well as the slow evoked vertex-potential were registered. The threshold behaviour, the characteristic curve and the latency curve of all potentials were obtained, and thereby damages of the central acoustic pathways found out. A topodiagnostic is tried by means of the alterations of the peripheral and central ERA, and by means of the informations described in the literature. A control registration, carried out four weeks later, demonstrated an improvement of the diagnosis.
