The gold standard for diagnosis of PNES is Inpatient video-electroencephalography (vEEG) monitoring.
Things that have been used but are unreliable:
- presence or absence of self-injury and incontinence,
- the ability to induce seizures by suggestion,
- psychologic tests, and
- ambulatory EEG.
These are insufficient for diagnosing PNES.
