New Study Links Falls to Increased Dementia Risk in Older Adults

Dementia affects 1 in 10 older Americans, making it a devastating condition many wish to avoid. Although the exact causes of dementia remain unclear, new research suggests a potential link between falls and an increased risk of developing the disease. A study published in JAMA Network Open in September revealed that older adults who suffer from falls may have a higher risk of being diagnosed with dementia. But what exactly is the connection, and what steps can older adults take to reduce this risk? Here’s what neurologists have to say.

What Did the Study Find?

The study examined data from over 2 million older adults who had sustained a traumatic injury. Researchers discovered that more than 10% of those who had experienced a serious fall were diagnosed with some form of dementia within a year. Overall, the study found that falling was linked with a 21% higher chance of receiving a future dementia diagnosis. As a result, the researchers recommend that anyone over the age of 65 who suffers a serious fall should be screened for dementia.

Does Falling Increase the Risk of Dementia?

According to experts, it’s unlikely that falling directly causes dementia. “Dementia is not going to ‘begin’ acutely after a fall,” says Dr. William Hu, associate professor and chief of cognitive neurology at the Alzheimer’s Disease Clinic at Rutgers Institute for Health. However, a fall may signal underlying issues. Dr. Hu explains, “Many people with dementia have balance issues.” A fall might alert doctors to evaluate the person’s cognitive, physical, and emotional health more closely. A hospital visit for a fall could lead to the discovery of pre-existing memory problems, which might result in a dementia diagnosis. Dr. Clifford Segil, a neurologist at Providence Saint John’s Health Center in Santa Monica, CA, adds that falling and losing consciousness could lead to structural changes in the brain that might worsen memory loss. However, Segil notes, “It is challenging to assign how a ground-level fall could worsen dementia.”

How to Prevent Falls

Falls are a serious concern for older adults, but there are several measures that can be taken to lower the risk: •Address Postural and Orthopedic Issues: Working with a trainer specializing in senior exercises can help improve strength, balance, and stability, according to Dr. Hu. •Wear Proper Footwear: Choose shoes that provide the necessary support to prevent slips and falls. •Secure Rugs: Make sure that rugs in your home are firmly attached to the floor. •Declutter Your Space: Keep your living space clear of obstacles to minimize tripping hazards. •Use Nightlights: Installing nightlights can help prevent falls during nighttime trips to the bathroom. •Avoid Rushing: Leave extra time when going to appointments or other destinations to reduce the risk of falling while in a hurry. If you or a loved one is concerned about fall risks, consulting with a healthcare provider can offer personalized recommendations to reduce the likelihood of falls and protect long-term health.
