Get a grip: individual variations in grip strength are a marker of brain health

TL;DR: The results suggest that perceptual decisions are mediated by oscillatory interactions within overlapping local and large-scale cortical networks.

TL;DR: Stand-alone handgrip strength should be considered an umbrella assessment of the body systems that contribute to strength capacity, and a panoptic measurement of muscle strength that is representative of overall health status, not a specific health condition.

TL;DR: Handgrip strength could be used for assessing cognitive status in aging Americans and strength capacity should be monitored in those with cognitive impairment, as strength capacity and cognitive function may parallel each other.

TL;DR: Findings over the past 15 years have demonstrated that changes in grip and leg extensor strength are not primarily due to muscle atrophy per se, and that to a large extent, are reflective of declines in the integrity of the nervous system.

TL;DR: The results suggest that T MT-A requires mainly visuoperceptual abilities, TMT-B reflects primarily working memory and secondarily task-switching ability, while B-A minimizes visu operceptual and working memory demands, providing a relatively pure indicator of executive control abilities.

TL;DR: The Trail Making Test is an accessible neuropsychological instrument that provides the examiner with information on a wide range of cognitive skills and can be completed in 5–10 min.

TL;DR: Neural reuse theories offer a distinct perspective on several topics of general interest, including the evolution and development of the brain, including (for instance) the evolutionary-developmental pathway supporting primate tool use and human language.

TL;DR: Objective measures of physical capability are predictors of all cause mortality in older community dwelling populations and may provide useful tools for identifying older people at higher risk of death.
