Seizure detection for nocturnal epilepsy

The NightWatch

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

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

When the NightWatch detects a potentially severe seizure, a warning is transmitted to a caregiver via a wireless signal to the armband’s corresponding base station.

Precise and versatile

The NightWatch detects various types of seizures with a high level of precision, including:

Tonic seizures

Tonic-clonic seizures

Hypermotor seizures

Clustered myoclonic seizures

Clinically proven effective

The 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.

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

Certified medical device

The NightWatch was tested and found to be safe in accordance with the European Union Medical Device Regulation and is produced according to the highest quality standards.

NightWatch Portal

The NightWatch can be connected to the internet so that you can obtain a readout of the wearer’s heart rate and motion data. This provides insight into how the night went and helps you better understand why the NightWatch gave notifications, if any. It eliminates any uncertainty about what happened during the night. In addition, it provides you and your neurologist with a greater insight into the intensity and duration of your seizures. Read the manual to find out how to connect the NightWatch to the online portal.
