Why the study?
Although electroconvulsive therapy generally does not cause prolonged seizures, cases of prolonged seizures have been reported, while other reports describe successful use for refractory status epilepticus and encephalitis symptoms.
Electroconvulsive therapy acts as a double-edged sword, with potential to cause prolonged seizures while also demonstrating efficacy in treating refractory status epilepticus and encephalitis symptoms.
ECT rarely induces epilepsy; leaves open mechanisms of occasional prolonged seizures after ECT.
Electroconvulsive therapy (ECT) is a widely used therapeutic option of drug-refractory psychiatric disorders. ECT treats psychiatric symptoms by inducing brief controlled seizures through electrical stimulation, but ECT does not generally cause prolonged seizures or epilepsy. However, several studies have reported cases of prolonged seizures after ECT. This review aimed to determine the mechanism of epileptogenesis with neurobiological changes after ECT. Contrary to epileptogenesis by ECT, several cases have reported that ECT was successfully applied for treatment of refractory status epilepticus. In addition, ECT might be applied to hyperkinetic movement and psychiatric symptoms of encephalitis. We also investigated the anticonvulsant mechanism of ECT and how it controls encephalitis symptoms.
