Aging and Cognition

  The effects of aging on cognition are not uniform. Rather, certain aspects of attention and memory are adversely affected by aging, whereas other cognitive domains are relatively preserved, and others even show positive age-related changes. Several overlapping cognitive theories have been advanced to explain these aging-related patterns, but none has prevailed yet. Cognitive neuroscience studies have focused on structural ...

Obstructive Sleep Apnea and Hallmarks of Aging

Obstructive sleep apnea (OSA) is one of the most common sleep disorders. Since aging is a risk factor for OSA development, it is expected that its prevalence will increase with the current increase in life span. In recent years, several studies have shown that OSA potentially contributes to functional decline, mainly prompted by chronic intermittent hypoxia and sleep fragmentation. Here, ...

Conserved regulators of cognitive aging: From worms to humans

Cognitive decline is a major deficit that arises with age in humans. While some research on the underlying causes of these problems can be done in humans, harnessing the strengths of small model systems, particularly those with well-studied longevity mutants, such as the nematode C. elegans, will accelerate progress. Here we review the approaches being used to study cognitive decline ...
