Abstract:
There have been a few reports of intraictal cessation of electroencephalographic (EEG) activity during electroconvulsive therapy. We present a case of a gentleman with recurrent severe major depressive disorder, who had a "start-stop-start" phenomenon of EEG activity during his electroconvulsive therapy treatment. This brief intraictal arrest of activity demonstrates the importance of continued EEG monitoring to confirm the postictal termination phase.
