Dear ILAE member

Dear ILAE member,

in preparation for ILAE guidance on diagnostic procedures for Psychogenic Nonepileptic Seizures (PNES) the ILAE Commission on Psychiatry would like to sample the views of ILAE members on the use of suggestive seizure induction in the diagnosis of PNES. The term “suggestive seizure induction” (or “provocation techniques”) covers diagnostic techniques using any form of suggestion, usually during electroencephalography (EEG) or video-EEG, to trigger a seizure when the diagnosis of PNES is considered. For example, this could include simple verbal suggestion, intravenous injection of placebo, suggestion based on hyperventilation or intermittent photic stimulation or a combination of techniques.

This questionnaire is being sent to clinicians around the world to assess current international practice in relation to the use of suggestive seizure induction. This survey is intended to inform the development of ILAE guidance on the video-EEG recording of patients in whom a diagnosis of PNES is considered possible or likely.

The survey can be completed even if no defined protocol is applied in your unit, or if suggestive seizure induction is not used in your unit.  Completion 31/07/2019 and should take no more than 10 minutes.

You can complete the survey by clicking on the following link or by pasting this link in your internet browser:

We would be very grateful if you could help the Commission on Psychiatry by answering this on-line survey. We welcome responses from multiple practitioners within the same unit.

Many thanks,

Markus Reuber for the ILAE PNES Task Force
