It has been demonstrated in a young man who develops seizure activity during reading, talking, and writing that the characteristic myoclonic jaw jerks and electroencephalographic spike wave discharges are induced and maintained by movements of articulation and mastication and that visual and ocular movements have no significance in the pathogenesis of this disorder. No appreciable latency exists between the spike wave discharge and myoclonic jaw jerk suggesting that both are triggered by a common paroxysmal focus. These observations and others previously reported are discussed and possible pathogenetic mechanisms considered.
