Once diagnosed, a medically supervised ketogenic diet is usually recommended as it can help to control seizures. The ketogentic diet is the current standard of care treatment, effectively controlling most seizures and improving some movement disorders in approximately two thirds of GLUT1 deficiency patients. There is also some evidence of some cognitive benefits for GLUT1 deficiency patients on a ketogenic diet, and most parents report improved energy, alertness, balance, coordination, and concentration, especially when the diet is started early in childhood.
