Scientists studied a large group of reports to see if certain proteins, called angiogenic factors, show up differently in people with Alzheimer's disease. These specific proteins are usually involved in growing new blood vessels in the body.
The goal was to see if measuring these levels in fluids like blood could help doctors identify the disease earlier or understand how it affects blood vessels. They looked at several different types of these markers, including one very common type called VEGF.
The results showed that there was no clear difference in these protein levels between people with Alzheimer's and healthy older adults. Even when looking specifically at the most common marker, the levels were similar across both groups.
Because the results were not significant, these specific markers may not be reliable tools for diagnosing the disease right now. However, studying these proteins helps scientists better understand how blood vessels and brain health are connected.
