Introduction Epilepsy affects over three million Americans and is characterized by recurring seizures, which typically involve problems with motor, sensory, and/or cognitive functions. These seizures may occur with or without loss of consciousness. One of the hazards of having a seizure, especially without notice or notification to caregivers, is the chance for the victim to become seriously injured. Epileptic seizures are often followed by vomiting where unattended, unconscious victims are at risk of choking. Therefore monitors have been developed to alert caregivers when a loved one is having a seizure. However, current monitors rely on total body movement and only work in bed. Therefore they have a high incidence of false alarms, unnecessarily alarming and sometimes waking caregivers, and provide no warning to the patient while awake. Technology description Researchers at the University of Washington have invented a method for monitoring and quantifying clinical seizures using the best available technology, including remote devices. The system includes a signal processor which analyzes electroencephalograph (EEG) and an electromyograph (EMG) signals for very specific characteristics that are indicative of an epileptic seizure. This method is completely automatic, may provide advance warning of a seizure for patients, and drastically reduces the number of false alarms that occur frequently with competing methods. Business opportunity Epileptic seizure monitors are in high demand, especially among parents of epileptic children. Stage of development An episodic monitor prototype is in development.
