    Abstract:
    The EEG, visual and auditory evoked potentials were examined in 4 patients with aphasia-epilepsy. All the examined manifested focal discharges of high-amplitude acute waves, peaks and peak-wave complexes in the temporal leads on the left or on the side of assumed dominance according to speech. The same leads showed transformation of auditory and visual evoked potentials to peak-wave complexes. The intensity of epileptic focal discharges on the EEG correlated with the gravity of aphasia, whereas effective treatment bringing about suppression of epileptic discharges in the temporal parts favoured speech recovery. Obviously, speech disorders in patients with aphasia-epilepsy are caused by neurodynamic disorders of information transfer and processing in the speech zones of the temporal lobe.
