Key result
More pronounced paroxysmal activity on the EEG during electroconvulsive therapy was associated with a more favorable therapeutic effect.
Why the study?
Is more intensive paroxysmal activity on EEG during electroconvulsive therapy associated with a higher therapeutic response?
Is more intensive paroxysmal activity on EEG during electroconvulsive therapy associated with a higher therapeutic response?
More intensive paroxysmal activity on EEG during ECT is associated with a better therapeutic response, which may inform stimulus dosing.
EEG records of electroconvulsions were evaluated according to a five-point semiquantitative scale grading the intensity of the paroxysmal activity. A more favorable therapeutic effect of ECT was found to be associated with more pronounced paroxysmal activity on the EEG. The role of this finding for the dosage of energy in the convulsive stimulus is discussed.
