RVCs groundbreaking clinical trials have demonstrated the positive effects of MCTs on not only seizure frequency, but also on behaviour and cognition. Robust clinical trials of both commercially available complete diets (developed based on RVC research) and of MCT dietary supplements (added to a dog新月直播檚 existing diet) ensures these findings can be implemented by the widest possible patient base.
RVC新月直播檚 pioneering epilepsy research has been enabled by a range of sources including the BBSRC, American Kennel Club Canine Health Foundation, Animal Care Trust, UFAW, and a number of industrial partners, including Boehringer Ingelheim and Nestl茅 Purina Pet Care.
In addition to clinical research at the RVC, our understanding of canine and feline epilepsy has benefited from RVC新月直播檚 VetCompass project, which has identified how common epilepsy and seizures are in the general population, while identifying a number of important risk factors for epilepsy, including breed predispositions.

Epilepsy in the most common chronic neurological disease in dogs, affecting around 0.6% of the 8.9 million dogs in the UK (around 53,000 dogs). Dogs with epilepsy experience recurrent seizures, which are most commonly managed by anti-seizure drugs (ASDs) with the aim of reducing how often, and how severely, affected dogs have seizures.
Unfortunately, around a third of these dogs will continue to seizure despite medical treatment, sparking a quest for 新月直播榓djunctive新月直播� non-drug therapies to improve the quality of life of the hardest-to-treat dogs, while also effectively supporting
wider understanding of epilepsy as a brain disease, and in pioneering new approaches to its treatment. We now know that
epilepsy is not only a seizure disorder, and instead, seizures are just one clinical sign in a complex network of brain changes, including behavioural comorbidities such
as anxiety, and cognitive changes such as impaired learning ability. Based on these findings, behavioural and cognitive outcome measures are now embedded in epilepsy clinical trial design, alongside traditional measures of seizure frequency and severity, and the impact of existing anti-seizure therapies on behaviour and cognition are being considered.
RVC has been pivotal in the game- changing development of dietary therapies for canine epilepsy, providing an evidence base for medium-chain triglyceride
(MCT) enriched or supplemented diets.
2008
RVC research describes the efficacy and tolerability of levetiracetam, a human epilepsy drug, in the treatment of drug-resistant canine epilepsy patients. This drug is now commonly used for drug-resistant dogs with epilepsy as an adjunctive therapy.
2015
Landmark publication of International Veterinary Epilepsy Task Force (IVETF) consensus papers on canine epilepsy, including epilepsy classification, diagnostic approaches, treatment and outcomes
2015
RVC launches the smartphone app Pet Epilepsy Tracker, the first app to facilitate owner monitoring and improvement of the lives of their epileptic pets, which is now used in >80 countries and has been downloaded >30,000 times
2013
RVC uses VetCompass 新月直播楤ig Data新月直播� to identify the prevalence and risk factors for idiopathic epilepsy in the UK, finding 0.6% of the canine population are affected
2015
RVC publishes the first review to explore the concept of 新月直播淓pilepsy beyond seizures新月直播�, reviewing the impact of epilepsy and its comorbidities on health-related quality of life in dogs
2014
First large-scale quantitative study describing the impact of epilepsy on canine quality of life is published (the EpiQOL) by RVC and collaborators
2008 2011 2013 2014
2015
2011
RVC publishes the first findings indicating that dogs with epilepsy experience behavioural changes following their epilepsy diagnosis, mirroring psychiatric comorbidities such as anxiety seen in people with epilepsy
2014
Pivotal systematic review is published defining the evidence base for antiepileptic drug efficacy
2014
RVC publishes a key report identifying clinical features of dogs with drug-resistant epilepsy, highlighting the importance of high seizure density rather than high seizure frequency per se as a risk factor for drug- resistance
2015
RVC publishes the first paper demonstrating positive effects of
a medium-chain triglyceride (MCT) enriched diet on seizure frequency in dogs with epilepsy
2015
RVC host an owner education event 新月直播�21st Century Management of Canine Epilepsy新月直播�, with speakers including human neurologists and people with epilepsy, as well
as internationally renowned neurologists
