A dual decline in memory and gait speed results in an increased risk of dementia amongst older adults.
Why this matters
Whilst slow gait is associated with an increased risk of dementia, this association is weak. A dual decline of memory and gait may have greater prognostic value in the diagnosis of dementia, as this could help identify individuals whose reduced gait speed is caused by neurodegenerative conditions as opposed to musculoskeletal conditions. Understanding the risk of dementia associated with a dual decline in memory and gait will help contribute to the development of preventative or therapeutic interventions.
