Abstract
As an exact description of the early stage of the Landau Kleffner Syndrome (LKS) is lacking, the present research has been undertaken in order to clarify this issue by studying data about sequence, duration and simultaneous appearance of the three characteristics of LKS: aphasia, epileptic manifestations and EEG-disturbances. Our results demonstrate a great variety in sequence and duration of the divers characteristics of LKS, indicating many pitfalls in diagnosing. The speech of the greater part of the children improved incompletely, while epileptic fits and EEG-abnormalities frequently disappeared in an earlier stage. Persistent severe language disorders can remain in failing to control clinical seizures and to normalize the EEG. The relation between seizure disorder (and EEG-abnormalities) and aphasia is not evident.
