About the Epilepsy Research Initiative
The AKC Canine Health Foundation (CHF) identified the need to better understand epilepsy in dogs with the launch of the Epilepsy Research Initiative. New studies that translated results from the research lab to the veterinary clinic were sought in 2014 in a collaborative response to donors, dog owners and the veterinary community impacted by canine epilepsy. In 2017, an initiative matched-funding challenge furthered CHF’s ability to support innovative research leading to better understanding of epilepsy and more effective treatments. The Epilepsy Research Initiative continues today to equip dog owners and veterinarians with the latest educational resources and further cutting-edge canine health research for this devastating condition.
Epilepsy affects one in every 100 dogs and refers to recurrent seizures resulting from an abnormality in brain function. The condition can be inherited (genetic epilepsy), caused by structural problems in the brain (symptomatic epilepsy), or may be of unknown cause (idiopathic epilepsy). Determination of the appropriate treatment for canine epilepsy, as well as prognosis for the condition, depends on accurate diagnosis of the type and cause of seizures.
Since 1995, CHF and its donors have invested more than $1.47 million in 21 grants to study canine epilepsy. Ongoing studies are exploring the use and effects of dietary supplements in the treatment of canine epilepsy, underlying genetics and disease mechanisms, and the role of the gastrointestinal tract and microbiome in the development and treatment of this disease.
$1.4M invested in epilepsy research since 1995.
Why Study It?
- Epilepsy is the most common medical neurological disorder in dogs
- Despite the development of new anti-epileptic drugs, many dogs' seizures remain uncontrolled using currently available therapies
- Knowledge gained may also improve our understanding of human epilepsy
- Understanding the mechanisms of anti-epileptic drug resistance may lead to more successful seizure management
- New treatment strategies may help dogs whose disease is uncontrolled by currently available therapies and those who cannot tolerate the side effects of current anti-epileptic drugs
- Identification of genetic risk factors may enable breeders to select against such factors and help owners of affected dogs make lifestyle and treatment decisions that improve their dog’s quality of life
