Objective napping, cognitive decline, and risk of cognitive impairment in older men.

Objective napping, cognitive decline, and risk of cognitive impairment in older men. Alzheimers Dement. 2019 Jun 11;: Authors: Leng Y, Redline S, Stone KL, Ancoli-Israel S, Yaffe K Abstract INTRODUCTION: Little is known about the longitudinal association between napping and cognitive impairment in older adults. METHODS: We used wrist actigraphy to measure naps in 2751 community-dwelling older men. Cognition was assessed repeatedly over 12 years, and clinically significant cognitive impairment was determined by physician diagnosis, Alzheimer's medication use or a significant cognitive decline. RESULTS: After adjustment for all covariates, men with longer napping duration had greater cognitive decline and higher risk of cognitive impairment. Men who napped for ≥120 min/day (vs.

METHODS: The exposures were baseline SDB, daytime sleepiness, insomnia, and sleep duration. The outcomes were change in episodic learning and memory (B-SEVLT-Sum and SEVLT-Recall), language (word fluency [WF]), processing speed (Digit Symbol Substitution), and a cognitive ...

I’ve been interested in this topic ever since, months ago, I watched an interview on CNN with the neuroscientist Matthew Walker. Eight hours of sleep, he says, is what we need. Eight hours of sleep in complete darkness (otherwise our brains won’t release melatonin, something I didn’t know…). An important point (again, something I didn’t know!): taking naps to catch up on our sleep doesn’t count. “Unfortunately, says Matthew Walker,” “sleep is not like the bank. You cannot accumulate a debt and then hope to pay it off at a later time.” And, he added, “Human...

Purpose of review This review provides a contemporary review of sleep apnea with emphasis on definitions, epidemiology, and consequences. Recent findings Amyloid β-42 is one of the main peptides forming amyloid plaques in the brains of Alzheimer patients. Poorer sleep quality and shorter sleep duration have been associated with a higher amyloid burden. Decreased sleep time in the elderly is a precipitating factor in amyloid retention. Studies have shown that the dysregulation of the homeostatic balance of the major inhibitory and excitatory amino acid neurotransmitter systems of gamma-aminobutyric acid (GABA) and...

, Juulia Paavonen E, Paunio T Abstract Melatonin is a circadian regulatory hormone with neuroprotective properties. We have previously demonstrated the association of the genetic variant rs12506228 near the melatonin receptor 1A gene (MTNR1A) with intolerance to shift-work. Furthermore, this variant has been connected to Alzheimer's disease. Because of the previously suggested role of melatonin signalling in foetal neurocognitive and sleep development, we studied here the association of rs12506228 with early development. The study sample comprised 8-month-old infants from the Finnish CHILD-SLEEP birth cohort ...
