 Official statistics report around 1000 deaths due to epilepsy in the UK each year Hanna et al 2002. Most of these deaths are un-witnessed and in many cases are believed to have been avoidable with timely assistance Langan et al 2000. A major problem is detecting nocturnal seizures to allow body re-positioning, to maintain an open airway and to administer rescue medication. There are several seizure alarms commercially available but are often unreliable with many false alarms. The aim of this study is to investigate a novel seizure detection system with a unique algorithm.
