The association of speech and language disorders with epilepsy is well
-known in children with acquired epileptic aphasia, involving such ent
ities as Landau-Kleffner syndrome (LKS), continuous spike wave in slow
wave sleep (CSWSS) epilepsy and benign partial epilepsy with centro-t
emporal spikes (BPECTS). The possible association between epilepsy and
a subgroup of children with developmental dysphasia is reported less
frequently. Lack of controlled prospective studies of sleep electroenc
ephalograms (EEG), and the use of medication, in children with develop
mental dysphasia, may deny appropriate treatment strategies to childre
n with severe developmental speech and language disorders.
