London, (IINA) - A team from University College London (UCL) and Royal Holloway University of London (RHUL) revealed in preliminary tests how decanoic acid, a fatty acid found in foods assigned to ketogenic diets, acts to block seizures in patients with drug-resistant epilepsy, UCL news reported.
Ketogenic diets are characterized by their high fat, low carbohydrate and controlled protein content. They have been acknowledged as a useful means of controlling the symptoms of epilepsy for many years, although the mechanism by which the diet has antiepileptic effects is unknown.
Now researchers have pinpointed decanoic acid as the fatty acid that blocks a key neurotransmitter receptor involved in brain activity. This study, published today in Brain, looked specifically at the medium-chain triglyceride diet, a form of ketogenic diet that includes a supplement called Medium Chain Triglycerides (MCT) oil, which offers high fatty acid content.
BRC-supported Professor Matthew Walker from the UCL Institute of Neurology, one of the researchers, said: “This discovery will enable us to develop improved formulations that are now likely to significantly improve the treatment of epilepsy. It will offer a whole new approach to the management of epilepsies in children and adults”.
Another of the researchers, Professor Robin Williams from the centre for biomedical sciences at the school of biological sciences at Royal Holloway, said: “By examining the fats provided in the diet, we have identified a specific fatty acid that outperforms drugs currently used for controlling seizures, and that may have fewer side effects. Finding that the therapeutic mechanism of the diet is likely to be through the fat, rather than widely accepted by generation of ketones, may enable us to develop improved diets”.
A clinical trial will begin in 2016 at UCLH and Great Ormond Street Hospital. Epilepsy affects over 50 million people worldwide and approximately a third of people diagnosed with epilepsy do not have seizures adequately controlled by current treatments.
