[Neurophysiologic control during treatment of cerebral ischaemia with danaden retard (author's transl)].

After a three month treatment with Danaden retard (Encephabol + nicotinic acid) a group of patients suffering from cerebral ischaemia showed (in contrast to an untreated group) a significant reduction of slow waves in the EEG, a significant improvement of the audiogram, a reduction of the optic and acoustic reaction time and of the peak latency of the visual evoked potentials.
