Johns Hopkins EpiWatch: App and Research Study


Johns Hopkins EpiWatch: App and Research Study


What is EpiWatch?

Johns Hopkins EpiWatch™ is an app for Apple Watch™ and research study. EpiWatch helps you manage your epilepsy by tracking your seizures and possible triggers, medications and side effects. You can view this information at any time, and a dashboard lets you share a summary of the data with your doctor or caregiver if you want. With EpiWatch, you can also send a message to family members or caregivers to let them know when you are tracking a seizure.

Track your Seizures as You Contribute Vital Data to Epilepsy Research

EpiWatch gives you a chance to help epilepsy research by sharing the data about your seizures. By entering data into EpiWatch, you can monitor your condition as you help Johns Hopkins researchers better understand epilepsy and potentially improve treatment.The researchers conducting this study are exploring whether a future app could potentially detect seizures, estimate their duration and contact caregivers, all using Apple Watch.

A new feature to EpiWatch enables participants to schedule continuous recording using a timer or to turn on continuous tracking in order to collect seizure data overnight or if they may be having seizures without warning symptoms. This may be particularly helpful for participants with histories of seizures during sleep.

EpiWatch Features

Please note: EpiWatch is not a seizure detector. You should not rely on EpiWatch to get help for your seizures.

How the App and Study Work

Johns Hopkins EpiWatch enables you to take surveys, enter daily journals and participate in other activities so you and Hopkins researchers can better understand your entire experience — your seizures, treatments and medication side effects. The app also includes an interactive game to measure a seizure’s impact on your responsiveness.

The collected data from the heart rate accelerometer and gyroscope in Apple Watch enable Johns Hopkins researchers to measure changes in your heart rate and movement during a seizure.
