Recurrent falls may signal an increased risk of dementia years before a formal diagnosis. Pooled evidence indicates that frequent falls are strongly associated with later dementia diagnoses, suggesting mobility changes could be used as an early warning marker.
A systematic review and meta-analysis of seven studies, involving over 2.9 million participants aged 40 and older without existing cognitive disease, examined the link between falls and subsequent dementia. Researchers found that a single fall increased future dementia risk by 20%, with multiple falls elevating the risk by 74%.
These findings suggest that recurrent falls could serve as a practical clinical marker for heightened dementia risk, prompting earlier cognitive screening and multidisciplinary review. However, further high-quality prospective research is needed to confirm causality and explore prevention strategies.
