Study to use tracking technology to predict epileptic seizure patterns

A brand new examine will use long run seizure monitoring expertise to watch and doubtlessly predict patterns in epileptic seizures utilizing steady information assortment of mind exercise in folks with drug-resistant epilepsy.

Epilepsy can dramatically have an effect on an individual’s day-to-day life and a 3rd of individuals with epilepsy can’t be managed with medicine. The Actual World Testing and Price-effectiveness Evaluation of Subcutaneous EEG (REAL-ASE) trial, which is being led by the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King’s Faculty London and funded by the NIHR, hopes to ascertain if the usage of a small implant that data mind exercise can enhance outcomes for therapy and care.

Whereas seizures can happen in predictable patterns, it’s troublesome to precisely observe how usually seizures happen because it depends on the particular person affected manually documenting their assaults in a diary. As seizures can have an amnesic impact, and may occur whereas an individual is asleep, precisely recording these occasions is commonly not attainable.

Subcutaneous implanted EEG is a brand new expertise. Typical EEG expertise both requires the particular person to be admitted to hospital or be examined at house, utilizing EEG electrodes glued to their scalp, which will be undertaken for just a few days. NHS ready lists for these assessments can fluctuate from months to years. Subcutaneous implanted EEG, the expertise being trialled on this examine, allows researchers to repeatedly document EEG in an unobtrusive method, for as much as 15 months, whereas the particular person lives their life fully usually.

The trial will recruit 33 folks with drug resistant epilepsy and implant a miniaturised electroencephalogram (EEG) system just below their scalp throughout a minimally invasive, twenty-minute process that’s carried out below native anaesthetic. Researchers will then monitor every particular person’s brainwaves over six months. By monitoring the brainwaves, researchers can depend the particular person’s seizures, which allows them to offer dependable info to clinicians, as a substitute for seizure diaries.

The examine’s principal investigator, Professor Mark Richardson, head of the College of Neuroscience and Paul Getty III Professor of Epilepsy at King’s IoPPN stated: “This expertise is a game-changer for epilepsy remedy because it allows us to detect and depend an individual’s seizures with accuracy. Clinicians treating folks with epilepsy ceaselessly make modifications to remedy within the hope of enhancing the lives of the third of individuals whose seizures haven’t but responded to therapy. We don’t know whether or not a change in therapy has been useful with out a very correct depend of seizures. Sadly, seizure diaries are sometimes not correct sufficient to guage whether or not therapy has led to any enchancment.

“What the usage of extremely long-term EEG opens up, is the chance, in future, of very precisely judging the impact of a change in therapy. We additionally anticipate that extremely long-term EEG will permit us to rapidly determine that somebody’s epilepsy is deteriorating in order that we are able to instantly step-up their care. This has the potential to be actually revolutionary for folks residing with a troublesome sickness.”

Dr Jonas Duun-Henriksen, director of Epilepsy Science on the Danish firm that developed the extremely long-term EEG answer, UNEEG medical, stated that the aim of the Actual World Testing and Price-effectiveness Evaluation of Subcutaneous EEG (REAL-ASE) trial is to look at what are the prices of introducing subcutaneous EEG into the present NHS workflow, and what are the benefits.

“Our distinctive system is the primary expertise to succeed in the market permitting extremely long-term EEG recording. It speaks on to the NHS objectives of enhancing affected person outcomes through patient-friendly, at-home, information assortment and evidence-based, individualised, patient-focused drugs. Our objective is to offer clear proof of system accuracy and acceptability for sufferers and professionals, and well being economics modelling of the influence on the NHS. If clinicians are measuring outcomes higher, seizure management is reached for extra folks, and clinicians can detect illness deterioration to keep away from folks being admitted to hospital.

“On the finish of the examine, we hope to have info that we are able to then take to the Nationwide Institute for Well being & Care Excellence (NICE) and commissioners, to show that it needs to be routinely funded.”

Alison Fuller, director of Well being Enchancment and Influencing at Epilepsy Motion, added: “It is a actually promising and thrilling departure from conventional seizure monitoring strategies in direction of serving to folks with epilepsy to higher perceive, and subsequently handle, their seizures. Seizure diaries solely provide a snapshot of true exercise, whereas steady monitoring might determine extra refined patterns and supply a way more correct image of what’s occurring.

“This new expertise additionally has the benefit of overcoming a number of the limitations or disruption folks expertise with extra standard EEGs. These usually require prolonged hospital stays or the necessity for sleep deprivation, which may have a knock-on adverse influence on seizures. 

“Having higher proof and data will undoubtedly enhance outcomes in security and high quality of care, which might in the end assist to scale back epilepsy-related deaths. Epilepsy Motion is proud to be supporting the examine and we look ahead to watching the way it modifications the panorama in present therapy strategies for folks with epilepsy.”

The examine will happen in London with assist from NHS trial centres in Newcastle, Cardiff, and Manchester.
