Epilepsy is a seizure disorder that affects about 3.4 million Americans. It is characterized by abnormal or hyperactive brain cell activity. Although the cause of epilepsy is not always known, certain forms of epilepsy are linked to genetic disorders, stroke, infection, and brain injury. Epilepsy is most commonly treated with medications, which reduce the probability of having a seizure. However, anti-seizure medications don’t work for everyone. Here, we investigate the keto diet and its potential health benefits. We interview patients, families, dietitians, and researchers to uncover the connection between food and epilepsy care.
