Neuroglycopenia Regardless of its immediate cause, most of the symptoms of hypoglycaemia arise as a result of alterations in cerebral metabolism (Fig. 20.4). The nature and severity of these neuroglycopenic symptoms depend largely upon the speed at which the blood glucose level falls, and whether habituation to hypoglycaemia has taken place.
