Kathryn Clark’s epilepsy had been under control for years. Then, in November 2014, she was hit by a tonic-clonic seizure – the kind that spreads to the entire brain and leaves the victim convulsing on the floor.
“I haven’t had too many of those in my life, and that one was out of the blue,” Kathryn says (pictured above). She was worried about looking after her children, then aged 2 and 4, if the seizures were coming back.
Her husband Ryan, an independent game developer, had an idea: program a smartwatch to detect movement characteristic of a seizure and text him a warning.
