title: [Particular aspects of bioelectric brain activity in post-traumatic Korsakoff syndrome].
abstract: Thirty two patients, 21 with recurrent and 11 with chronic Korsakoff's syndrome of traumatic genesis, and 20 healthy subjects were studied, using visual and spectral coherent EEG analysis and investigation of three-dimensional localization of dipolar beta 1-activity sources (13-20 Hz EEG bands). In Korsakoff's syndrome, negative prognostic significance of a stable increase of EEG beta 1-activity coherence generated by a limited number of sources, preferably of frontal basal and stem localization, was found. In the context of clinical data, this EEG phenomenon may be related to inhibited state of corresponding cortical areas.
