Seizure detection for nocturnal epilepsy

NightWatch warns caregivers remotely in the event of possible epileptic seizures during sleep. NightWatch was invented and developed by a consortium of Dutch neurologists, patient organisations, universities and hi-tech industries and recommended by patients.

NightWatch consists of a comfortable wireless arm module that closely tracks heart rate and motion to detect seizures while the wearer is lying in bed.

When NightWatch detects a potentially dangerous seizure, a warning is transmitted via a wireless signal from the arm module to the corresponding base station to warn a caregiver.

Precise and versatile

NightWatch can detect various types of seizures with a high level of precision, including:

  • Tonic-clonic seizures
  • Tonic seizures

  • Hyperkinetic seizures

  • Clustered myoclonic seizures

Clinically proven effective

NightWatch was successfully tested over thousands of nights by the SEIN and Kempenhaeghe epilepsy centres and found to be significantly better than the alternative methods available.

NightWatch detects up to 96% of the most dangerous seizures.
