EEG DELTA BAND SPECTRAL POWER: DIFFERNECES BETWEEN UNILATERAL AND BILATERAL ECT SEIZURES

EEG was recorded from right and left frontal leads during bilateral (n=11) and unilateral (n=l4) ECTs. The seizure EEG was analyzed using East Fourier ′Transform and the spectral power oj the Delta (1-4 Hz) band was computed. The spectral power on both sides was similar in the bilateral ECT.

Sumario:EEG was recorded from right and left frontal leads during bilateral (n=11) and unilateral (n=l4) ECTs. The seizure EEG was analyzed using East Fourier ′Transform and the spectral power oj the Delta (1-4 Hz) band was computed. The spectral power on both sides was similar in the bilateral ECT. Unilateral ECT produced asymmetry in the early - (first 8 seconds after stimulus offset) and mid - (17-32 seconds after the stimulus offset) siezure phases; the spectral power was lower on the unstimulated hemisphere. Studies to elucidate the relevance of EEG delta band of the seizure to therapeutic potency of ECT are suggested.
