‘Not surprising’
Commenting on the findings for this article, Claire Sexton, DPhil, senior director of scientific programs and outreach at the Alzheimer’s Association, Chicago, noted that AAC is a marker of atherosclerosis and is associated with vascular health outcomes.
Therefore, it is “not surprising it would be associated with dementia too. There’s been previous research linking atherosclerosis and Alzheimer’s disease,” Dr. Sexton said.
“What’s novel about this research is that it’s looking at AAC specifically, which can be identified through a relatively simple test that is already in widespread use,” she added.
Dr. Sexton noted that “much more research” is now needed in larger, more diverse populations in order to better understand the link between AAC and dementia – and whether bone density testing may be an appropriate dementia-screening tool.
“The good news is vascular conditions like atherosclerosis can be managed through lifestyle changes like eating a healthy diet and getting regular exercise. And research tells us what’s good for the heart is good for the brain,” Dr. Sexton said.
The study was funded by Kidney Health Australia, Healthway Health Promotion Foundation of Western Australia, Sir Charles Gairdner Hospital Research Advisory Committee Grant, and the National Health and Medical Research Council of Australia. Dr. Sim and Dr. Sexton have reported no relevant financial relationships.
