Dementia is a devastating disease that impacts one in 10 older Americans. While many people aim to avoid developing dementia, the exact causes of the condition have remained largely a mystery. Recent research published in JAMA Network Open in September has identified one potential risk factor for developing dementia: falls.
The study analyzed data from over 2 million older adults who had sustained traumatic injuries. Researchers found that more than 10 percent of these individuals were diagnosed with some type of dementia within a year following their fall. Notably, falling was linked to a 21 percent higher risk for a future dementia diagnosis.
Experts recommend that anyone over the age of 65 who experiences a significant fall should be screened for dementia. William Hu, MD, an associate professor and chief of cognitive neurology at the Rutgers Institute for Health, notes that while dementia is unlikely to begin acutely after a fall, the incident often prompts further cognitive evaluation.
Clifford Segil, DO, a neurologist at Providence Saint John's Health Center in Santa Monica, CA, adds that falls can lead to structural changes in the brain, potentially worsening memory loss. However, he emphasizes the challenge in directly linking ground-level falls to the progression of dementia.
Falls remain a significant concern for older adults, but there are preventive measures that can be taken. Addressing postural and orthopedic issues, as well as engaging in exercises designed for seniors, can help improve strength, balance, and stability. Consulting with a medical provider can offer personalized guidance for those worried about fall risks.
