According to CBS News, a teenager has received the first implantable electronic device to help treat severe epilepsy. This patient suffers from up to 250 seizures per day and also suffers from them at night. Current data states that 58% of sudden deaths related to epilepsy occur while the patient is asleep, therefore making this device groundbreaking for its around the clock monitoring. The device by Cyberonics, AspireSR, is implanted in the chest and monitors nerve activity around the heart. Often times before a seizure a patient will experience an increase in heart rate. By monitoring the heart rate, the device can help to detect an increase in nerve activity as well as send signals via the vagus nerve up to the brain which helps to decrease the number of seizures a patient experiences.
