Pseudoseizures, also known as psychogenic seizures, are episodes of altered movement or behavior that resemble epileptic seizures but have no associated electroencephalogram (EEG) findings and no identifiable physiological cause. The episode lacks certain characteristic features of a true seizure but simulates a generalized tonic-clonic seizure. Less often, pseudoseizures mimic complex partial, atonic, myoclonic, or absence seizures. Unlike what occurs in a true tonic-clonic seizure, individuals report a marked degree of awareness during the seizure. The motor behaviors are also unusual, consisting of brief irregular clonic movements (e.g., thrashing and jerking). Unusual flapping, arching of the back, and pelvic thrusting can also be observed.
