Have to be careful with this. I am interested (have not started) in using brain waves to track epilepsy episodes and hopefully none of this makes tracking/capture difficult for consumers. Granted most of the good devices require implant so some level of permission is implied but the scope may be assumed. Still shutting down in the early stages may seem convenient but it could be limiting too.

If the start of an episode can be tracked (sub-second) perhaps there are some counter measures that can be taken to disrupt/subdue the electrical storm that sustains the episode. That detection pattern is something that is unique to the patient so there is custom learning involved. The hope is with enough samples we may be able to detect some hidden 'core' pattern - similar to warnings for earth quakes - and mitigate the episode or use that to go into a heightened sensitivity mode to watch out for the more custom signal.
