Hypothesis
Patients presenting with PNES would have their typical event in less than 24 hours.
Conclusion
Patients with PNES typically have their first habitual event within seven hours of starting home video telemetry.
Supporting Evidence
- The mean time to first habitual PNES onset was seven hours.
- Patients with abnormal MRI findings had their events earlier than those with normal findings.
- Men presented significantly earlier with their habitual PNES event than women.
Takeaway
This study found that people with certain types of seizures called PNES usually have their first seizure within seven hours of starting a video recording at home.
Methodology
A retrospective analysis of a cohort of patients who underwent home video telemetry for suspected PNES.
Potential Biases
Self-reporting may introduce bias as patients may not accurately describe their events.
Limitations
The study relied on self-reported data without witness validation, and some patients were excluded due to technical issues.
Participant Demographics
The majority of participants were female (84%) with a mean age of 38.
