It is plausible to propose that the modulation of GLUT4 is triggered by a combination of factors indicating cellular sensitiveness to insulin. In addition, some critical symptoms, including cognitive deficits and certain movement difficulties, tend to persist in Glut1 Deficiency patients treated by a ketogenic diet, raising the question whether Glut1 Deficiency is caused simply by a lack of proper brain energy or if there are more complicated and widespread systems and processes affected.
