Not Medical Advice: There aren't seizure figures but we found one patient where the physical strain of his seizures forced him to burn around 2,000 calories a day.
As per Heraldextra.com, this patient suffered anywhere between several hundred and several thousand seizures a day.
Studies have shown that glycolysis increases during seizures, and that the glycolytic metabolite lactic acid can be used as an energy source.
Glycolysis breaks down glucose and forms pyruvate with the production of two molecules of ATP. The pyruvate end product of glycolysis can be used in either anaerobic respiration if no oxygen is available or in aerobic respiration via the TCA cycle which yields much more usable energy for the cell.
Tonic-clonic seizures are the type of seizure most people recognise. They used to be called grand mal seizures. Someone having a tonic-clonic seizure goes stiff, loses consciousness, falls to the floor and begins to jerk or convulse.
