Engineering Devices to Treat Epilepsy
From: NASA Tech Briefs - 01/2010 - page 21

Intelligent implantable epilepsy devices will likely be tuned to individual
patients, and may need to predict events rather than merely detect them. 

Many technologies have been proposed for treating epileptic seizures, with
the ultimate goal being implantation of stimulators or drug infusion devices
in the brain to abort seizures before clinical onset. Device designs range
from “blind” stimulators to “intelligent” devices, which are triggered by
detecting or predicting seizure onset. Intelligent implantable epilepsy
devices will likely process multiple channels of data, be tuned to individual
patients, and may need to predict events rather than merely detect them.
