falls May Signal Early Dementia Risk, New Research Suggests
BOSTON, MA – A large new study reveals a notable link between falls in older adults and subsequent dementia diagnosis, potentially identifying a previously overlooked early warning sign of cognitive decline. Researchers found that 10.6% of patients who experienced a fall were diagnosed with dementia within a year, representing a 21% increased risk compared to those with other types of injuries.
The study, published in JAMA Network open, highlights a growing body of evidence suggesting falls aren’t simply accidents, but could indicate underlying cognitive issues – or even accelerate the advancement of dementia.
“We treat injuries and provide rehabilitation services, but we often overlook the underlying risk factors that contribute to falls, despite a growing body of evidence suggesting a link between falls and cognitive decline,” explained Dr. Alexander Ordoobadi, lead author and resident physician at Brigham Hospital.
Researchers believe the relationship is bidirectional. Cognitive decline can increase the risk of falls, but the trauma from a fall may also hasten the progression of dementia and lead to earlier diagnosis. ”Cognitive decline may increase the risk of falls, but trauma from falls may also accelerate the progression of dementia and increase the likelihood of later diagnosis,” stated Molly Jarman, assistant professor in the Department of Surgery and associate director of the Center for Surgery and Public Health at Brigham Hospital.
The findings suggest falls could serve as ”precursor events” prompting further cognitive screening. Dementia’s prevalence increases with age,affecting 2 to 4% of individuals over 65,and rising sharply to 23% of those aged 80 and older,according to data from Inserm. Loss of motor function, a common consequence of falls, is also recognized as a potential early indicator of cognitive impairment.
