Clinical Trial Summary

Breath and sweat samples will be collected from people who have been admitted to hospital after a potential seizure and analysed by the team. The researchers then hope to identify a pattern of small molecules that can distinguish seizures from other events, and perhaps determine the severity of the seizure.

Description:

Determining whether someone has had an epileptic seizure, or another event, can be challenging and result in the wrong diagnosis. A 'seizure test' used after the event would therefore be very helpful. Researchers have used small molecules released from the body in breath and sweat to detect cancers and other diseases; this study will determine whether a similar method can be used to detect whether someone has had an epileptic seizure.

Intervention

Other:
• Sample Collection
Patients will have breath samples collected by blowing into a bag, and sweat samples collected by gauze. These samples will be collected at various timepoints whilst the patients are admitted on the ward.
