Recent and ongoing advances in mapping and isolating human epilepsy ge
nes will: (i) modify the classification of the epilepsies; (ii) base a
ntiepileptic drug development on defined epilepsy mutations; and (iii)
spur the development of somatic cell and/or germ line therapy for the
fatal progressive myoclonus epilepsies and, eventually, the chronic g
eneralised and partial epilepsies. In the next century, advances in th
ese 3 areas will dramatically change the diagnostic, therapeutic and p
rognostic approach to patients with epilepsy, and will probably elimin
ate some genetic epilepsies within 2 or 3 generations.
