title: Benign epilepsy of childhood with centrotemporal spikes.
abstract: Benign epilepsy of childhood with centrotemporal spikes (BECT) is the most common partial epilepsy syndrome in the pediatric age group, with an onset between age 3 and 13 years. The typical presentation is a partial seizure with parasthesias and tonic or clonic activity of the lower face associated with drooling and dysarthria. Seizures commonly occur at night and may become secondarily generalized. They are usually infrequent and may not require antiepileptic drugs but, if treated, they tend to be easily controlled. Children with BECT are neurologically and cognitively normal. The EEG shows characteristic high-voltage sharp waves in the centrotemporal regions, which are activated with drowsiness and sleep. In this typical form, BECT is easily recognized. However, atypical cases are common and the definition of BECT can become blurred. Although further investigations are not required in cases with typical clinical and EEG findings and normal neurologic examinations, neuroimaging studies may be required in atypical cases to rule out other pathology. The long-term medical and psychosocial prognosis of BECT is excellent, with essentially all children entering long-term remission by mid-adolescence.
