Type 2 diabetes patients are more likely to live with dementia in old age than other patients. New evidence may shed some light on why that is.
A new study from Australia found that patients with type 2 diabetes may have more tangles and thinner cortexes in their brains than patients without the disorder — even when not currently affected by Alzheimer's disease.
Brain tangles are created when proteins (called tau) collapse. In a healthy brain, the tau help stabilize the brain pathways that transport essential nutrients between cells and neurons. When the tau collapse, they can form twisted threads that block these pathways. This can eventually lead to brain cell death.
