Older age linked to a memory-first pattern of low scores
The ratio comparing age’s associations with memory-first and strength-first transition rates was 1.110 per five years across four cohorts.
Limit: The age contrast weakened when low scores used age-specific cutoffs

An observational analysis included 46,356 adults aged 50–100 from four long-term cohorts. Participants began follow-up above the study’s low-score thresholds for both muscle strength and episodic memory, or recall of events. Each had at least three assessments measuring both abilities.
Older age was associated with a relative pattern of memory reaching low scores first. Limitations in daily activities were associated with a relative pattern of muscle strength reaching low scores first. These associations persisted after accounting for starting scores and multiple health conditions. Diabetes was associated with higher rates of reaching low scores in both areas, without a clear difference between the two patterns.
Why it matters
Muscle strength and memory are linked in later life. The analysis addressed whether their first transitions to low function share the same associated factors.
Caveats
These observational associations cannot establish a biological sequence or clinical screening thresholds; participants were aged 50–100. Using age-specific cutoffs weakened the age contrast, and diabetes findings varied with the low-score cutoff.
