Drop In Sugar Levels In The Brain 'could Lead To Memory Loss And Eventual Alzheimer's'
Glucose is a fuel for the hippocampus which plays a key role in processing and storing memories. It and other regions of the brain rely exclusively on glucose for fuel and without glucose, neurons starve and eventually die. The brain is fuel hungry as it accounts for just two per cent of body weight but consumes a fifth of all absorbed daily calories. Yet one of the earliest signs of Alzheimer's is a decline in glucose levels in the brain and this appears in the early stages of mild cognitive impairment, before symptoms of memory problems begin to surface. But scientists have been divided whether this was a cause or consequence of the neurological dysfunction. The new study by Temple University in Philadelphia showed unequivocally that glucose deprivation in the brain triggers the onset of cognitive decline, affecting memory in particular. And this may explain why diabetics are more at risk of dementia as long-term small decreases in glucose leads to brain damage. Professor Dr Domenico Praticò at the at the Lewis Katz School of Medicine said: "There is a high likelihood that those types of episodes are related to diabetes, which is a condition in which glucose cannot enter the cel Continue reading >>
