The US Food and Drug Administration has approved a new smartphone app that can detect and interrupt nightmares in adults with PTSD.
The NightWare app, runs on the Apple Watch and Apple iPhone and adapts to the individual.
During sleep, Apple Watch sensors monitor heart rate and body movement. These data are then used to create a unique sleep profile using a proprietary algorithm.
Using a gyroscope and accelerometer, similar to fitness watches, the NightWare app detects that a patient is experiencing a nightmare based on changes in heart rate and movement. It provides slight vibrations through the Apple Watch to arouse the patient and interrupt the nightmare, without fully awakening the patient.
The NightWare app is available by prescription only and is intended for use in adults aged 22 years and older with PTSD.
