New seizure warning device developed

31 July, 2000

A new seizure warning device called Forecast has been developed. Lee Hively, of Oak Ridge National Laboratory in Tennessee, has developed the device.

Forecast monitors the brain's activity using EEG electrodes, and compares it with stored information. Large differences from normal activity, and a 'warming up' of brain activity, can indicate an imminent seizure.

Lee Hively, in an interview with New Scientist magazine, says "the person could immediately stop doing what they're doing, like get out of the swimming pool or get off the ladder, and go and lie down." The person can have up to eight minutes warning that a seizure may occur.

Clinical trials are now being conducted with plans to make the equipment wearable.
