New Onset Seizure Disorder Following Electroconvulsive Therapy.

Electroconvulsive therapy (ECT) is an effective treatment for many psychiatric illnesses including refractory depression, catatonia, bipolar disorder, and schizophrenia, along with neuropsychiatric diseases such as dementia and Parkinson's disease. The emergence of a seizure disorder after the initiation of ECT is a rare but severe occurrence. It can become challenging for clinicians to determine whether ECT should be continued. We present a case of a 73-year-old female with schizoaffective disorder who received a total of 173 ECT treatments over the course of five years for breakthrough psychosis due to medication nonadherence. After five years of treatment, she experienced her first episode of tonic-clonic seizure activity. We review the current evidence and discuss factors that should be considered when treating such an individual.
