We were talking about diabetes in the last chapter, and before we entirely leave there, it’s important to know that Alzheimer’s disease has sometimes been called “diabetes of the brain.”
Even in the earliest stages of the devastating memory-destroying disease, the brain’s ability to metabolize sugar is diminished. For decades, science has concluded that the characteristic amyloid plaques and tangles in the brains of Alzheimer’s sufferers interrupt the delicate circuitry of thought transmission and memory.
The characteristic beta-amyloid clusters of proteins called “plaques” and clumps of dead and dying nerve and brain cells, called “tangles” are the generally agreed upon indicators that Alzheimer’s disease exists.
Think of the brain’s network of dendrites and neurons as an electrical system. Those plaques and tangles block the transmission of the electrical current or information through those circuits.
What’s the link?
Many scientists now call Alzheimer’s “type 3 diabetes.” What’s the link between Alzheimer’s and diabetes?
Here are some things that science has proven in recent years that have advanced our understanding of this terrible disease:
We know that the risk of Alzheimer’s is doubled in people with diabetes. Some studies say the risk is four-fold.
We also know that insulin resistance defines Type 2 diabetes, sometimes called “diabesity,” is primarily caused by eating too many simple carbs and sugars and not enough fat.
We also know that insulin resistance starts the brain damage ca Continue reading
