[Evoked potentials in movement epilepsy (a report on 4 observations) (author's transl)].
A study of evoked potentials; visual (V.E.P.) auditory (A.E.P), and somatosensorial (S.E.P.) in 4 cases of movement epilepsy. Their correlation to clinical findings (provoking factors, control of the attacks), electroencephalographic and neuroradiological (scanner) data, shows that two types of information can be obtained: lesional and functional. Three types of modification can be described: a) the topographically limited changes in E.P. depend on lesional localization; b) the increase in amplitude of the late components and of the post-discharge of the E.P. ("paroxystical" aspect) appear to be a characteristic common to all epilepsies, whatever the mechanism; c) the abnormal exaggeration of the E.P. during voluntary movement seems to be a dynamic element peculiar to movement epilepsy. The information given by E.P.'s in some well-defined cases of epilepsy suggest that it is possible to draw conclusions from tests of the capacity for sensory-motor control to enable functional therapy of some attacks.
