運動原性てんかん

抄録

Two cases with seizures induced by movement were presented and the nomenclature of this entity was discussed.
The clinical manifestations of the cases were characteristic and the peculiar seizures were induced by sudden voluntary movement without loss of consciousness, often associated with emotional excitement. Age of onset was six and eight years respectively. One case showed the athetoid-dystonia and the other the torsion spasm. Duration of the attacks was several seconds to one minute. Good response to anti convulsant medication was observed. In addtion to the seizures induced by movement, one case had a past history of afebrile grand mal attacks and another case showed psychomotor seizures.
The titles hitherto reported of this entity are divided into two groups: one is the name showing the form of the paroxysmal involuntary movement and the other is that showing the pathogenesis of the reflex epilepsy. The pathogenesis of the reflex epilepsy appeared to be confirmed through the exper ience of the cases with two types of seizures in one individual. Since this is a sort of reflex epilepsy, the name of “kinesigenic epilepsy” is preferable to “paroxysmal choreoathetosis”.
