Electroconvulsive therapy (ECT) has been used to treat severe treatment-resistant major depressive disorder. Multiple psychotropic medications are usually prescribed in high doses prior to or concomitantly with ECT. Little is known about the interaction of ECT with psychotropic medications. ECT is known to induce seizures, but its tendency to induce absence seizures is not. We present a case of a 44-year-old female, on multiple psychotropic medications, who had frequent atypical absence seizures for many days after ECT. Electroencephalography (EEG) confirmed atypical absence seizures by the presence of typical 2.5 to 3 Hz generalized sharp and slow waves with disorganized background activity.
