A single fall after the age of 40 could increase one’s future dementia risk by over 20 per cent, reveals a new review of studies conducted in China. For people experiencing multiple falls after this age, their future risk could increase up to 74 per cent, say scientists from the Changchun University of Chinese Medicine. "Recurrent falls may serve as a potential clinical marker for identifying individuals at higher risk," researchers wrote in the study published in the Journal of Post-Acute and Long-Term Care Medicine . Dementia and falls both affect elderly populations and are commonly associated with ageing, with many studies probing the link between the two. Studies show there could be common neurological issues linked to both falls and dementia, indicating that falls could be an early symptom of cognitive decline.
