Stress was the most common trigger, linked to 37% of seizures, followed by lack of sleep (18%), menstruation (12%) and overexertion (11%).
Apple announced that researchers from Duke University, Johns Hopkins and Oregon Health & Science University are launching new medical studies using ResearchKit.
The research is looking to develop an effective method for predicting seizures; the apps for the study are now in beta testing, and should be out on Sept. 18.
The App for Life will get new features that will detect abnormal movements and alert loved ones when the user is experiencing these symptoms or has fallen.
The quiet, small device has a battery that can last for weeks, and will help measure stress, epileptic seizures, as well as activity and sleep.
The system has three components: a smart clothing (shirt + hat), smartphone app and cloud service, where data is uploaded and analyzed by doctors.
The campaign, looking to raise $90,000, will run through June 13, 2014 with a goal to develop a next generation of the SAMi system.
