title: [EEG pattern during treatment of parkinsonism with L-dopa].
abstract: The authors studied the dynamics of EEG changes in 27 patients treated with L-dopa. The records obtained before treatment were compared with those made during treatment and with the clinical manifestations. In 8 cases the EEG pattern was normal before treatment and 6 of them improved (three-fourths of this subgroup). In 19 cases the EEG pattern was abnormal and 10 of them improved (about 50%). Some intensification of temporal episodic complexes in EEG records was observed during treatment without concomitant changes of clinical manifestations. In 2 cases with slowed down background activity in initial records psychic disturbances of hallucinatory obnubilation type developed requiring withdrawal of treatment. This psychotic reaction was characterized in EEG with increased intensity of generalized slowing down of EEG activity.
