Researchers at NeuroVista are developing an implantable device designed to predict a seizure before it happens and warn a patient to get ready.

In their system, an implanted telemetry device receives brain wave data and transmits it to a receiver, where proprietary mathematical algorithms transform the information into a real-time warning system.

The device could also be a warning system for other neurological disorders that can have unpredictable flare-ups, like migraine headaches or severe depression. The company plans its first feasibility clinical trial in 2009.
