Epileptic seizures can be predicted through researchers' software
2 University of Windsor profs say it can predict an epileptic seizure 17 minutes in advance
Two University of Windsor professors have designed software they say can predict an epileptic 17 minutes before it happens.
“Up until now, the best prediction was a few minutes ahead and had an accuracy of 50 to 60 per cent,” Prof. Robin Gras said in a post on the University of Windsor's website. “We got 17 minutes with 100 per cent accuracy."
Gras and Abbas Golestanti, a PhD student in the School of Computer Science, analyzed the brain’s electrical activity, specifically the electroencephalography (EEG) readings of patients.
Thirty minutes of readings plugged into the software is enough data to give someone with epilepsy 17 minutes of advance warning of a seizure.
The researchers based their findings on data from 21 epileptic patients.
Their test results were published in Scientific Reports in October.
Gras and Golestanti have patented the software, and now need a device that can constantly monitor a patient’s EEG.
“If you have this device on you all the time, it reads your EEG values and 17 minutes in advance it can ring and say: You will have trouble in 17 minutes. Stop your car. Go to a safe place. Phone someone to help you,” Gras said.
Gras said the method is "innovative" and based on chaos theory, which allows people to make long- term predictions of the evolution of complex systems.
The pair originally developed the software to predict the next financial crisis. They've also analyzed 100 years of climate data and evaluated the next 30 years for climate change.
"We used financial time series, medical time series and climate time series to evaluate our method," reads the pair's research in Scientific Reports. "The results we obtained show that the long-term prediction of complex nonlinear time series is no longer unrealistic."
Gras believes their method can potentially be applied to many other events, such as predicting heart attacks, earthquakes and the onset of Alzheimer's disease.
