As glucose is the primary energy source for neuronal cells, any condition that lends itself to creating GLUT3 deficiency, as in the case of dietary restrictions, hypoxic–ischemia or significant hypoglycemia, can result in a panoply of neurodevelopmental disorders such as dyslexia, autism spectrum disorder (ASD), epilepsy, and attention-deficit/hyperactivity disorder (ADHD) [6,7,8,9,10]. This evidence concerns the gene SLC2A3 and attention deficit-hyperactivity disorder.
