- Insulin resistance is linked to the build-up of amyloid-beta and tau proteins, the hallmark signs of Alzheimer’s. Insulin and amyloid-beta are both broken down by the same enzyme (IDE); when insulin levels are too high, the enzyme is "distracted" by insulin, allowing toxic amyloid to accumulate.
- Chronic high blood sugar damages both large and small blood vessels. In the brain, this reduced blood flow can starve cells of oxygen and essential nutrients, contributing to cognitive decline.
- High blood sugar triggers chronic inflammation throughout the body and brain, which can damage brain cells and accelerate the progression of dementia.
