Implantable device provides seizure alerts

Australian researchers conducted the first human trials of an implantable device developed to alert epilepsy patients whose seizures aren’t controlled by medication that they may be about to have one.

Electrodes implanted on the surface of the brain detect electrical activity and connect to a unit placed under the skin of the chest, which transmits the data to a wireless hand-held device. When abnormal brain waves are detected, this unit predicts the likelihood of an oncoming seizure.
