A new method for automatic integrative interpretation of the awake electroencephalogram (EEG) was developed. We first determined all the items necessary for EEG interpretation following the procedure that a qualified electroencepharographer (EEGer) goes through for the visual inspection of awake EEG, and then defined each item quantitatively. For the automatic interpretation, we determined specific EEG parameters for each item so that they can fit the graded judgment of the item by the qualified EEGer as closely as possible. Those specific EEG parameters were actually calculated from periodograms of the EEG time series. The automatic EEG interpretation system thus established was applied to the EEG data of 14 subjects, and the results were compared with those obtained through the visual interpretation by the EEGer. This automatic EEG interpretation was found to be in good agreement with the visual interpretation by the EEGer in most EEG records, The proposed method for automatic integrative interpretation of EEG can be used clinically as an assistant tool for neurologists and EEGers, and may be the first step for its clinical application to the hospital use.
