Acquired aphasia in childhood with seizure disorder: a heterogeneous syndrome.
The authors report six children with acquired aphasia of unknown etiology. The clinical picture was clearly different from that seen in the usual childhood aphasias and resemble other cases initially reported as "syndrome of acquired aphasia with convulsive disorder". All had associated paroxysmal EEG abnormalities, and 5 have had clinical seizures. The language disorder has improved or remained stationary and no other neurological signs have developed. Our review of the literature and the study of our personal cases show no uniform clinical picture in these children. Three different clinical patterns seem to emerge. The first group show rapid onset and recovery of aphasia, frequent fluctuations in the severity of the language deficit typical of so-called epileptic aphasia. These children appear to have a better prognosis. The second group show worsening of the aphasic deficit after repeated seizures or episodes of aphasia. In the third group progressive deficit in language comprehension (auditory agnosia) with a variable degree of recovery and rare or no clinical seizures. The possible significance of the EEG abnormalities has been discussed and the importance of the aphasia on general behavior and the problems of differential diagnosis have been stressed.
