Mendelian forms of benign myoclonic epilepsies where a chromosomal locus has been defined include (1) the autosomal dominant (AD) juvenile myoclonic epilepsy (JME) in chr. 6p11, (2) the autosomal dominant childhood absence epilepsy which evolves to JME in chr. 1p, (3) familial adult myoclonic epilepsy of Yasuda and Inazuki, and (4) possibly JME within the idiopathic generalized epilepsy susceptibility gene in chr. 8 reported by Zara et al (1995). Other myoclonic epilepsy syndromes with onset in the first year of life (Aicardi's Neonatal (Early) Myoclonic Encephalopathy, West's Syndrome, Dravet's Severe Myoclonic Epilepsy, and Dravet's Benign Myoclonic Epilepsy of Infancy), in early childhood (Lennox-Gastaut-Dravet Syndrome, Myoclonic Variant of Lennox Gastaut Dravet Syndrome, Myoclonic-Astatic Epilepsy of Doose, Benign Myoclonic Epilepsies (BME), or even in late childhood (Childhood Absence Epilepsy with myoclonias, vs. Myoclonic Absence Epilepsy) are probably genetically complex diseases. Amongst the progressive myoclonus epilepsy syndromes, specific mutations have already been defined in Unverricht Lundborg disease, ceroid lipofuscinoses 3 or Spielmayer Voight syndrome within Battens disease, sialidosis, dentadorubropallidoluysian atrophy and the mitochondrial syndrome MERRF. Most recently our laboratories established the locus for Lafora's disease in chr. 6q and results are speedily moving towards the definition of its mutation.

The author first reviews the definition of myoclonia as an epileptic crisis differentiated from tonic crises and infantile spasms. He reviews the prevalence and incidence found in bibliographic data, under the following headings 1. Early myoclonic encephalopathy or neonatal myoclonic encephalopathy 2. Early epileptic syndrome with bursts of suppression or Otahara's syndrome. 3. West's syndrome. 4. The benign myoclonic epilepsy syndrome of children. 6. Syndrome of myoclonic epilepsy in non-progressive encephalopathy. 7. Early myoclonic epilepsy of children or Dose's syndrome. 8. Lennox-Gastaut syndrome. 9. Syndrome of epilepsy with absences in children. 10. Myoclonic absence epilepsy syndrome. 11. Landau-Kleffner syndrome and the syndrome of continuous slow spike-and-wave epilepsy during slow sleep. 12. Photosensitive epilepsy. 13. Absence epilepsy in young patients. 14. Juvenile myoclonic epilepsy. 15. Syndrome of gran mal epilepsy on waking. 16. Progressive myoclonic epilepsies. The author reviews 6,450 cases, 408 patients who had myoclonic crises, that is 6.3%. The differences seen in this total group of patients were: the myoclonic crises which presented alone, myoclonic crises accompanied by simple typical absences, those initially accompanied by generalized tonic-clonic crises and those presenting typical absences, tonic-clonic generalized crises and myoclonus simultaneously. The course of the different groups is analyzed.
