10-Second heart rate variability and cognitive function in old age
Key result
Lower 10-second HRV is linked to worse reaction time and processing speed in older adults.
Why the study?
Is lower 10-second heart rate variability associated with worse cognitive function and decline in older adults?

Implication
May flag cognitive vulnerability in older adults; leaves open causal links and clinical utility.
Structured PICO
Is lower 10-second heart rate variability associated with worse cognitive function and decline in older adults?
P
Population
Older adults
I
Intervention
Lower 10-second heart rate variability (HRV)
O
Outcome
Performance in reaction time and processing speed, and decline in processing speed
Lower 10-second heart rate variability is associated with worse cognitive performance and faster cognitive decline in older adults, independent of traditional cardiovascular risk factors.
