Neurologische Universitätsklinik München, FRG.

We have investigated the effect of piracetam on photoparoxysmal responses in 3 patients with progressive myoclonus epilepsy. With doses of up to 10 g/day, elimination of photoparoxysmal responses was achieved in all 3 patients. Corresponding to EEG improvement, the clinical performance improved slightly in 2 patients and definitely in 1 patient when piracetam was added to their medication of valproate and clonazepam. According to our data, medical treatment of myoclonus with piracetam is justified particularly in myoclonus of cortical origin.

D002998	Clonazepam	An anticonvulsant used for several types of seizures, including myotonic or atonic seizures, photosensitive epilepsy, and absence seizures, although tolerance may develop. It is seldom effective in generalized tonic-clonic or partial seizures. The mechanism of action appears to involve the enhancement of GAMMA-AMINOBUTYRIC ACID receptor responses.	2H-1,4-Benzodiazepin-2-one, 5-(2-chlorophenyl)-1,3-dihydro-7-nitro-,Klonopin,Antelepsin,Rivotril,Ro 5-4023,Ro 54023
