| Abstract |
Impairment of physical performance might identify older people at higher risk of dementia over time. The present study evaluated handgrip strength as independent predictor of cognitive decline. Observational, prospective. Follow-up duration: 11.2 ± 0.8 months. Geriatric outpatients center. 104 consecutive stroke- and dementia-free older adults (44% men, ages 80.2 ± 5.4 years). The Clinical Dementia Rating scale and the Clock Drawing Test (CDT) were administered. Handgrip strength was assessed using a Jamar hand dynamometer. Brain magnetic resonance imaging studies at 1.5 T were performed. White matter damage was expressed as severity of white matter hyperintensities (WMHs). Longitudinal changes in cognitive function were expressed as 1-year decline in CDT performance. A robust association was observed between baseline handgrip strength and 1-year cognitive decline after multiple adjustment. Of note, the strength of such association was only minimally attenuated after adjusting for deep WMHs extent (β coefficient for handgrip strength = 0.183, SE= 0.038, p= 0.007, R2= 0.58). Handgrip strength predicted accelerated 1-year decline in cognitive function, assessed by CDT, in a sample of older adults. Future studies are needed to elucidate the causal mechanisms linking limitations in physical function with dementia risk. |

Attention Score in Context
This research output has an Altmetric Attention Score of 7. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 05 May 2017.
All research outputs
#5,213,966
of 25,728,855 outputs
Outputs from The journal of nutrition, health & aging
#629
of 2,003 outputs
Outputs of similar age
#78,929
of 325,490 outputs
Outputs of similar age from The journal of nutrition, health & aging
#12
of 35 outputs
Altmetric has tracked 25,728,855 research outputs across all sources so far. Compared to these this one has done well and is in the 79th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 2,003 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 13.0. This one has gotten more attention than average, scoring higher than 66% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 325,490 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 74% of its contemporaries.
We're also able to compare this research output to 35 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 62% of its contemporaries.
