Anticonvulsant drugs don’t work for about 20 percent of people with epilepsy. That’s 10 million people worldwide. For them, many research groups have been studying brain-wave data to find patterns that can predict an oncoming seizure.


At Columbia University’s Medical Center, researchers have implanted a new kind of brain-wave recording device in seven patients. They hope that the device will point the way to predicting seizures—and some day, preventing them.
