title: Degenerative progressive myoclonic epilepsy electrokymographic observations.
abstract: Clinical and pathological findings in two cases of degenerative progressive myoclonic epilepsy (PME) are described. The clinically difficult task of differentiating a "cerebellar" tremor from an action myoclonus is emphasized. Simultaneous electroencephalography and electrokymography was done, using capacity to ground transients for recording hand movements. This method was found useful in corroborating the cerebellar nature of the remaining disorder, after successful treatment of the myoclonic element with anticonvulsants.
