Abstract
An awake electroencephalographic (EEG) record, which consists of background EEG activity and paroxysmal abnormality such as spikes, gives significant information for clinical diagnosis. The interpretation of spikes is the most important item in the diagnosis of subjects with epileptic disorders. A method for automatic interpretation of awake background EEG was already been proposed by the authors. However, the existence or interpretation of the spikes was not considered in the previous method. In order to make the automatic EEG interpretation system a more effective tool on the clinical scene, a method of creating EEG spike reports based on results of an adaptive spike detection method developed in the past, was proposed and investigated. Parameters and rules for making report of EEG spikes were constructed by taking into account the method of visual inspection used by an electroencephalographer. Then, the proposed method was integrated with the method for automatic interpretation of awake background EEG. The proposed method was applied to the data acquired from 3 subjects, and satisfactory results were obtained as compared with those of visual inspection. The integrated system has achieved a total interpretation of awake EEG of both backgorund EEG and spikes in paroxysmal abnormality. The method will be a powerful tool for various clinical applications.
