A Study to Evaluate Radio Signal Characterization of Seizures


About this study

The purposes of this study are to passively collect data on body movements, heart rate, breathing, and sleep physiology using radio signal analysis in subjects who are being monitored in the Mayo Clinic Epilepsy Monitoring Unit for clinical purposes, and to determine if analysis of the radio signal data (as recorded by the Emerald device) may be eventually used to detect/predict nocturnal seizures.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Consented adult (18+) male and female subjects who are admitted to the Mayo Clinic Hospital (Saint Marys Campus) Inpatient Epilepsy Monitoring Unit.
  • Have a confirmed diagnosis of epilepsy (by a Mayo Clinic Neurologist).

Exclusion Criteria:

  • Subjects who are pregnant or may be pregnant.
  • Pediatric patients (< 18 years of age).
  • Subjects who are unable to provide consent.
  • Those admitted primarily for classification of indeterminate (possibly non-seizure) events.
  • Subjects who plan to have more than one additional person in the room with them during nocturnal hours (10 pm – 6 am) (excluding clinical providers).
  • Subjects who have an implanted vagal nerve stimulator or other neurostimulation device.
  • Patients with implantable drug delivery systems or implanted cardiac devices (including pacemakers and defibrillators).
