Abstract: In an attempt to specify the cognitive impairments associated with the poor verbal outcome usually described for epileptic aphasia, we investigated the verbal abilities and dichotic listening performances of five children with Landau and Kleffner Syndrome, several years after complete recovery of epilepsy. The five patients showed a specific impairment in the auditory verbal short-term memory involving the phonological processing system. Unilateral extinction of dichotic stimuli (contralateral to the epileptogenic focus) was also observed. These effects of unilateral extinction and reduced auditory verbal short term memory are seen as consequences of temporal cortex dysfunction.
