The CODES trial is a randomised controlled study looking at a treatment for Dissociative (Non-Epileptic) Seizures.
Dissociative Seizures are attacks that look like epilepsy, typically with a blackout. The person may have shaking movements or fall down and lie still. Dissociative Seizures are genuine, common and distressing for patients and those around them.
The CODES trial is testing whether a type of talking treatment, Cognitive Behavioural Therapy (CBT), helps patients with Dissociative Seizures.
The trial, funded by NIHR (National Institute of Health Research), is designed to find out whether CBT is worth having in addition to standardised medical care. It could be that it is, it might be that it isnt - that is what the trial is designed to find out.
