Seizure detection for nocturnal epilepsy

NightWatch warns caregivers remotely in the event of possible epileptic seizures during sleep. Conceived by Dutch neurologists and recommended by patients.

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

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

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

  • Tonic seizures

  • Tonic-clonic seizures

  • Hypermotor seizures

Clinically proven effective
