Dysphagia, speech disorders and centrotemporal spikes-waves

Repeated paroxysmal oropharyngeal fits consisting of sialorrhea and speech arrest are described in a 5 year-4-month old patient. Investigations were initially oriented towards a laryngeal or a gastrointestinal disease. Electroencephalographic tracings showed repeated bilateral centrotemporal spikes-waves discharges which sometimes were associated with bilateral facial clonic contractions synchronous with anarthria and sialorrhea. Consciousness was preserved. Attacks were related with a cluster of fits of a partial epilepsy. Transient pseudo-bulbar palsy (anterior opercular syndrome) resulted from seizures: loss of identifiable speech, drooling with difficulties in swallowing, absence of palatal movements and of the gag reflex. Intellectual functions remained normal. Other investigations were all normal (CT scan, MRI, cytologic and immunological CSF studies). With common anticonvulsant drugs (Valproate and Carbamazepine) seizures resolved within a few weeks. These findings suggest that this particular epilepsy is an unusual type of benign partial epilepsy with centrotemporal (or Rolandic) spikes.
