Psychogenic nonepileptic spells (PNES) are paroxysmal movements or sensory events that resemble epileptic seizures but lack corresponding ictal electrographic changes. A confirmed diagnosis of PNES is only accomplished via video electroencephalogram (vEEG) monitoring. Prior to diagnosis, patients are often assessed with neurodiagnostic imaging and their conditions treated with anticonvulsant medications, both of which are of limited clinical value and contribute to the higher cost of care. In this study, we assessed the relationship between the semiological features of PNES, medication regimen, or psychiatric comorbidities and the frequency of referrals for brain imaging tests prior to diagnosis of PNES.
