Sleep disorders may increase cognitive problems particularly in those at risk for Alzheimer's. People who carry a genetic susceptibility to Alzheimer's disease appear to be at greater risk of diminished cognition from sleep-disordered breathing than those without the susceptibility, according to new research.

Alzheimer's disease is a scourge and any research that helps prevent it is most welcome. It isn't prevalent in my family but I've seen families that have had to deal with this and it is tough. I hope this research into sleep can help lessen the effects of Alzheimer's disease in the future.
Cannot sleep due to stress? Here is the cure. Everyone empirically knows that stressful events certainly affect sound sleep. Scientists have found that the active component rich in sugarcane and other natural products may ameliorate stress and help having sound sleep. Source 6u.
Can writing your 'to-do's' help you to doze? Study suggests jotting down tasks can. Writing a 'to-do' list at bedtime may aid in falling asleep, according to a new study. Research compared sleep patterns of participants who took five minutes to write down upcoming duties versus participants who chronicled completed activities. Source 4t.
Can't sleep? Could be down to genetics. Researchers have identified specific genes that may trigger the development of sleep problems, and have also demonstrated a genetic link between insomnia and psychiatric disorders such as depression, or physical conditions such as type 2 diabetes. Source 7u.
Napping can help tired teens' performance in school. Researchers have found a positive relationship between midday-napping and nighttime sleep. They believe it might be key to boosting neurocognitive function in early adolescents. The team examined adolescents in Jintan, China, measuring midday napping, nighttime sleep duration and sleep quality, and performance on multiple neurocognitive tasks. Habitual nappers (Who napped more often) tended to have a better nighttime sleep. Source 3q.
A peek into the interplay between sleep and wakefulness. The ventrolateral preoptic nucleus (VLPO) in the brain plays a critical role in the initiation and maintenance of sleep, while the lateral posterior part of the hypothalamus contains neuronal populations implicated in maintenance of arousal. Now, a new study reveals that these arousal-related neurons are heavily innervated by GABAergic neurons in the preoptic area including the VLPO. The work provides important information to understand the mechanisms that control animals' sleep/wakefulness states. Source 5s.
