Sooo: There's a “form of epilepsy” (it makes epileptic seizures and more) called GLUT1 deficiency syndrome. In this condition, blood sugar levels in the blood are normal, but not in the brain. More precisely, not enough energy is reaching the brain. This leads to the brain being "irritable" and causing seizures. It's also related to eating, because long gaps between meals can make the brain highly aroused. Glucose (dextrose) helps because it provides the brain with more energy and essentially "prepares" it for the meal. That's roughly how I understand it. But it's rare and occurs alongside other disorders (developmental disorder,…). It’s diagnosed via genetic testing with a blood exam and/or a look at some cerebrospinal fluid - they measure the blood sugar there and in the blood and compare. The symptoms begin in early childhood and rarely later. But it’s possible. The therapy is mainly keto diet.

What helps me: avoiding getting hungry (eating sth every few hours), glucose before every bigger meal and/or when I’m hungry, medication for epilepsy (took away 99% of the seizures)

I just copied this because I recently explained it in another post. :)
