Type 2 diabetes may triple the risk for Alzheimer's or other dementia, according to new research from the Alzheimer's Research Trust. Here's how it seems to work.
A person who is overweight will have alot of inflammation because fat cells send out inflammatory chemicals. This causes damage by free radicals. The brain is particularly at risk because the brain consists mostly of fat, and the greatest damage by free radicals targets fat.
Type 2 diabetes raises blood sugar. Sugar can stick to proteins in the brain, causing tangles and other damage.
Type 2 diabetes is often accompanied by high blood pressure which carries a risk factor for mini-strokes. Mini-strokes leave dead tissue and poor circulation in the brain.
A scenario ripe for Alzheimer's or other dementia is in the making, if things don't get turned around.
"First of all it is important to try and avoid becoming a type 2 diabetic. In the majority of cases following a healthy diet, exercising regularly and maintaining an ideal body weight can prevent this disease. There is a great deal of information about this topic in our book called 'Diabetes Type 2 You Can Reverse It Naturally'."
