Bone Density Linked to Brain Health Decline
24 Sep
Summary
- Lower spinal bone density correlates with faster cognitive decline.
- Bone density may indicate changes in brain white matter.
- Routine CT scans could potentially assess brain aging risk.
A new study indicates that bone health could offer insights into brain function. Researchers have discovered that lower bone density in the spine is associated with a more rapid decline in cognitive abilities.
This association extends to changes in the brain's white matter over time. Specifically, reduced bone mineral density was linked to increased white matter hyperintensities and a greater decline in white matter integrity.
These findings suggest a shared vulnerability between bone and brain health, rather than bone loss directly causing cognitive decline. Biological factors like metabolic issues or dyslipidemia may play a role.
Exploratory analyses also hinted at stronger associations in participants with diabetes and women, although these require further investigation.
Importantly, the study raises the potential for using existing CT scans to estimate bone density. This could offer a non-invasive way to identify individuals at higher risk for accelerated brain aging, without additional scans or radiation.
However, experts caution that these results are preliminary and not yet sufficient for clinical use or as a dementia screening tool.
