The relationship between computerized quantitative EEG (QEEG) and intellectual, memory and psychornotor test performance was studied in a series of 52 patients suffering from a cardiac valvular disease. After controlling the effect of age, several signifcant positive correlations were found between verbal intellectual and memory performances and the alpha mean frequency, as well as the total mean frequency of the EEG activity. Non‐verbal performances were more closely related to age than to brain electrical activity. Of the single test, Vocabulary had the closest connection with the QEEG parameters. No lateral asymmetry was foundin the QEEG—test performance correlations. The alpha mean frequency appeared most promising in studying the QEEG—intelligence relationships.
