Primary reading epilepsy

Abstract
Patients with primary reading epilepsy complain of a sensation of jaw snapping or jaw opening when reading. Such symptoms are most likely to develop when the patient reads aloud or when the reading material requires concentration. A generalized seizure is likely to occur if he persists in reading once the myoclonic jaw movements appear. These patients do not have seizures under any other circumstances, and their neurologic examinations are normal. Their electroencephalograms are normal during the resting state but may show diffuse paroxysmal activity when jaw-opening movements are provoked. In this paper, the clinical features of two further cases of primary reading epilepsy have been described. We have speculated regarding the pathogenesis of the syndrome and emphasized the role which repetitive proprioceptive impulses may play.
