A group of scientists has recently discovered a link between high glucose levels in the brain and symptoms of memory loss, which could lead to Alzheimer's.

The brain breaks down glucose, or sugar in its most basic form, and it is used to provide energy to make the brain function. However, individuals with brains that had a hard time breaking down glucose showed more signs of brain plaques and tangles, which are indicators of Alzheimer's. (Related: High sugar-based diet, obesity strongly linked to causing Alzheimer's and dementia.)

According to the scientists, the study has proven a significant link between high levels of glucose in the brain and the symptoms of Alzheimer's disease. Individuals with brains that were less efficient at breaking down glucose showed worse outward dementia symptoms like memory loss, which is often associated with Alzheimer's disease.
