What Oxygen is used and how many calories are burned in grand mal epileptic seizures?

During a grand mal epileptic seizure, the brain's increased activity leads to a higher demand for oxygen, primarily in the form of aerobic metabolism. This spike in oxygen consumption can result in a temporary increase in caloric expenditure, typically estimated to be around 30 to 50 calories during the seizure. However, the exact amount can vary based on the duration and intensity of the seizure. It's important to note that the overall metabolic effects can differ significantly among individuals.
