Primary reading epilepsy: therapeutic efficacy of clonazepam in one case

Primary reading epilepsy is a rare form of reflex epilepsy, in which reading is the specific stimulus evoking attacks. The authors report a case of an 18-year-old man who since the age of 17 presented myoclonic jaw jerking provoked exclusively by reading. In one episode, in which reading was not interrupted, jerks were followed by a generalized convulsive seizure. EEG with routine activating procedures was normal, while EEG recorded during reading showed bilaterally synchronous paroxysmal small-voltage spikes, more prominent in frontocentral regions, coinciding with jaw myoclonus. Complete clinical seizures control and EEG normalization were achieved with clonazepam 2 mg daily in a 24-month follow-up.
