Aging and the Change in Fatigue and Sleep

Fatigue is prevalent in the population and usually linked to sleep problems, and both are related to age. However, previous studies have been cross-sectional. The purpose of the present study was to investigate the trajectories of sleep and fatigue across … Continue reading

Untreated Sleep Apnea in Children Can Harm Brain Cells Tied to Cognition and Mood

Study reports reduced gray matter in areas of the brain associated with mood and cognition in children with obstructive sleep apnea. MRI scans link chronically disrupted sleep to widespread brain cell damage. A study comparing children between 7 and 11 years … Continue reading

Sleep after learning strengthens connections between brain cells and enhances memory

Researchers show for the first time that sleep after learning encourages the growth of dendritic spines, the tiny protrusions from brain cells that connect to other brain cells and facilitate the passage of information across synapses, the junctions at which … Continue reading

Why Does Sleep Become Disrupted in Old Age?

Age-related sleep disruptions are not due to alterations in activity of individual neurons as previously believed, researchers report. The brain maintains its ability to generate local neural oscillations during sleep throughout the lifespan, according to a study of young and … Continue reading

Melatonin during a Nap Fosters Learning

Sleep helps to protect and renew hippocampus-dependent declarative learning. Less is known about forms of learning that mainly engage the dopaminergic reward system. Animal studies showed that exogenous melatonin modulates the responses of the dopaminergic reward system and acts as … Continue reading

How the brain consolidates memory during deep sleep

Research strongly suggests that sleep, which constitutes about a third of our lives, is crucial for learning and forming long-term memories. But exactly how such memory is formed is not well understood and remains, despite considerable research, a central question … Continue reading
