Correlation between CSWS and aphasia in Landau-Kleffner syndrome: a study of three cases.
We report three typical cases of Landau-Kleffner syndrome with varied courses. The very frequent discharges in sleep EEGs, often showing the patterns of CSWS (continuous spike-waves during slow-wave sleep), either typical (spike-wave complex occupying over 85% of slow-wave sleep duration) or atypical (spike-waves occupying less than 85% of slow-wave sleep), were presented in all our cases. The CSWS seems correlated with aphasia in our cases. Since the disappearance of CSWS might be indicative of a lagged improvement in aphasia, we suggest that sufficiently long-term treatment with anticonvulsants and/or corticosteroids is worthwhile, if the EEG is improved significantly by this treatment.
