Christine Keneally describes the experience of Rita Leggett, who has epilepsy, participated in a trial called Neurovista. An implant gave her to advance warning of impending seizures so she could ensure she was safe when they happened.
Prof Terry O'Brien is quoted: "Specialists know [a seizure] when they see one, he said, but ... nobody ha[s] come up with a unifying description. At the most basic level, he said, a seizure is a rogue electrical discharge, an oscillation that moves in time and space, a bit like a tornado. Understanding isn’t helped by the fact that epilepsy is not a single disease, but rather the brain’s response to a variety of pathologies. Consequently, people with epilepsy often struggle with other conditions."
