Commercially available seizure detection devices: A systematic review

Area of Science:

• Neurology
• Biomedical Engineering
• Medical Devices

Background:

• Epilepsy is linked to significant morbidity and mortality.
• Seizure detection devices can aid individuals with epilepsy, caregivers, and clinicians by providing alerts, reducing SUDEP risk, and enabling objective seizure tracking.

Purpose of the Study:

• To systematically review and synthesize the characteristics of commercially available seizure detection tools and devices.

Main Methods:

• A systematic search identified commercially available seizure detection products for consumer use.
• Performance data was gathered through a systematic review of these products.

Main Results:

• Twenty-three seizure detection/alerting products were identified, employing diverse detection mechanisms (movement, autonomic changes, EEG, audio).
• Only 8 devices have published peer-reviewed performance data, primarily for tonic-clonic seizures.
• Optimal device selection depends on factors like device purpose, age, seizure type, and patient preference.

Conclusions:

• Seizure detection devices hold potential to decrease morbidity and mortality in select epilepsy patients.
• Clinicians need to understand device characteristics to effectively counsel patients on suitability and optimal choices.
