Diets that are higher in fat and significantly lower in carbohydrates have shown remarkable potential for reducing seizures in individuals with drug-resistant forms of epilepsy, especially in children. While researchers have observed a shift in the gut’s microflora from this type of diet, the exact nature of these changes and their connection to seizure prevalence remain unknown. A recent study conducted by researchers from the University of California, Los Angeles (UCLA) has shed new light on how the food we consume can alter our gut microbiome, influencing various neurological functions associated with epilepsy.
Epilepsy affects approximately 50 million people globally, causing recurrent electrical discharge across the brain. While most individuals with epilepsy benefit from medication, around 30 percent experience drug-resistant epilepsy. This refractory condition is often challenging to treat, leaving patients searching for alternative solutions. The ketogenic diet, often referred to as the keto diet, has gained attention for its potential in reducing seizures among patients with treatment-resistant epilepsy. However, only a small percentage of patients can maintain the keto diet over a prolonged period due to its restrictions and side effects, such as gastrointestinal issues and kidney stone risks.
Researchers at UCLA aimed to understand how specific nutrients, consumed through the keto diet, could lead to neurological changes that reduce seizure occurrence. Led by UCLA molecular biologist Gregory Lum, the team conducted an investigation into the gut biomes of epileptic mouse models and their interaction with chemicals produced by the microbiota, as well as the products of genes in the hippocampus. They first verified the effects of the keto diet on the gut biomes of 10 children with drug-resistant epilepsy. After collecting samples from the children who had been on the diet for approximately a month, the researchers introduced these microflora samples into the guts of engineered mice.
The results were promising, as the microbiomes altered by the keto diet proved to be more effective in reducing seizures in the mouse models compared to samples collected prior to the children starting the diet. Additionally, the researchers identified metabolic changes related to energy production, amino-acid metabolism, and specific forms of fatty acid oxidation in both humans and mice. Interestingly, the mice that received microbiomes influenced by the keto diet also exhibited changes in gene activity in the hippocampal area, which has been previously associated with epilepsy.
Understanding how these specific changes dampen seizure conditions is crucial for the development of new treatments. The ultimate goal is to devise therapies that do not rely on a highly restrictive diet. Lum states, “Narrowing down the functions of the microbes that are beneficial toward seizure protection can potentially lead to new ways to enhance the efficacy of the ketogenic diet or to mimic its beneficial effects.”
This research not only offers hope to those living with epilepsy but also highlights the significant role that gut microbiota plays in our overall health. The study emphasizes the importance of considering these organisms when designing personalized diets, as they can influence our body’s various functions. As we continue to uncover the intricate relationship between diet, gut microbiomes, and neurological conditions, it becomes increasingly important to prioritize not only our own health but also the health of our gut microbes.
The groundbreaking research conducted at UCLA provides valuable insights into the mysterious connection between diet and epilepsy. By investigating the impact of the keto diet on gut microbiomes, researchers have identified key metabolic changes and gene activity associated with epilepsy. These findings offer hope for the development of alternative treatments for drug-resistant epilepsy, reducing the reliance on highly restrictive diets. Furthermore, this study underscores the essential role of gut microbes in influencing overall health and highlights the need to consider their well-being when making dietary choices. As we strive for a better understanding of this intricate relationship, we can begin to harness the potential of our gut microbiomes for improved neurological health.
