A Retrospective Study Reviewing Timing to Onset of Habitual Psychogenic Non-Epileptic Seizures in a Home Video Telemetry Cohort

Our study highlights that on average, patients with PNES will rapidly have their first habitual event within an HVT study (mean time to event onset of seven hours), consistent with the current literature. This raises the question of whether HVT study duration could be reduced to release study resources and aid departmental efficiencies. We also observe the novel finding that men presented significantly earlier with their habitual PNES event than women, and that abnormal imaging findings were also significantly associated with an earlier time to event onset, although the reason for this association is yet to be determined.
