Low bone mineral density at the femoral neck is a significant risk factor for dementia in older adults.
Resumen
The content discusses the correlation between low bone mineral density (BMD) at the femoral neck and the increased risk of dementia in older adults. It highlights the findings from the Rotterdam Study, emphasizing the need for further research to understand the relationship between bone density and memory loss. The study suggests that bone loss could potentially serve as an early indicator of dementia risk, prompting targeted screening and improved care for individuals with poor bone health. The content also explores the association between low BMD and dementia, shedding light on the potential role of bone health as a prodromal feature of dementia. Additionally, it touches upon the brain-bone axis and the impact of bone health on brain functions like memory and cognition.
Key Highlights:
- Low BMD at the femoral neck is a robust risk factor for dementia in older adults.
- Further studies are needed to explore the connection between bone density and memory loss.
- Bone loss may precede clinical symptoms of dementia, indicating a potential risk marker.
- The study suggests that poor bone health could be a prodromal feature of dementia.
- The brain-bone axis may play a role in regulating brain functions through bone-generated hormones.
Estadísticas
"those with the lowest, vs higher, BMD at the femoral neck had a twofold higher risk of developing dementia over 10 years."
"lower BMD at the femoral neck (per standard deviation) correlated with a higher risk for all-cause dementia."
"Only BMD at the femoral neck was related to incident all-cause dementia in the first 5 years of follow-up."

"Our research has found a link between bone loss and dementia, but further studies are needed to better understand this connection between bone density and memory loss." - Mohammad Arfan Ikram, MD, PhD
"The link may very well be the little known 'brain-bone axis' — where our bones actually regulate our brain." - Shaheen Lakhan, MD
