Psychogenic nonepileptic seizures (PNES) are episodes of seizure-like symptoms that are not associated with epileptiform discharges on electroencephalogram (EEG). They can be remarkably difficult to distinguish from epileptic seizures: both may involve alterations in mental status and behavior; sensory or perceptual disturbances; as well as simple or complex motor patterns [1]. The diagnosis of PNES may be suggested by: (i) Failure of multiple anticonvulsants (ii) “seizures” triggered by stress and other triggers atypical for epilepsy (iii) lack of incontinence or injury such as tongue biting during events.
