The EEG symmetry of 65 patients with different kinds of cerebrovascular disorders was analyzed using the Polarity Coincidence Correlation Coefficient (PCC) and the Signal Energy Ratio (SER) measurements. Significant differences were found between the pathology group and a control group of normal subjects for both measures. A discriminant function was applied for both values with an overall accuracy of 80%. It is concluded that since the method does not require an experienced electroencephalographer it may be useful for the diagnosis of cerebrovascular pathology and for screening purposes.
