Alzheimer can spread it roots if you lose even one night's sleep

Disruption in one night's sleep can lead to getting Alzheimer's disease, a recent study has stated.

The interruption in the sound sleep for a single night aggravates the level of tau protein in any young male's body, thus gives rise to the chances of developing the disease.

Our study focuses on the fact that even in young, healthy individuals, missing one night of sleep increases the level of tau in blood suggesting that over time, such sleep deprivation could possibly have detrimental effects, says study's author, a neurologist.

As defined by the Alzheimer's Association, tau is the name of a protein that helps in stabilising the internal structure of the brain's nerve cells. An abnormal build-up of tau protein in the body can end up in causing interior cells to fall apart and eventually developing Alzheimer's.

When you get more of that deep sleep and you get the REM sleep in the normal amounts, that improves clearance of abnormal proteins which we think is good, said another neurologist, who was not a study author.

Earlier studies have also shown that getting deprived of sleep can allow higher tau development and accumulation. Thus that poor sleep can hasten the development of cognitive issues.

Researcherrs caution that the study is small and inconclusive, and acknowledged they were not able to determine what the increased levels might mean.

This study raises more questions than answers, agreed a researcher. What this is telling us is that we have to dig more deeply. Despite something we do for a third of our lives, we know so little about sleep and we're learning every day, particularly when it comes to sleep and dementia.

Developing Alzheimer's diseases could be due to disrupted sleep

Losing a night's sleep can be the reason behind developing Alzheimer's, study reveals.

The interrupted sleep schedule for even a night increases the level of tau protein in a young male's body thus increasing the chances of developing Alzheimer's disease.

According to CNN, the report was published on Wednesday in Neurology, the medical journal of the American Academy of Neurology

"Our study focuses on the fact that even in young, healthy individuals, missing one night of sleep increases the level of tau in blood suggesting that over time, such sleep deprivation could possibly have detrimental effects," said study author Dr Jonathan Cedernaes, a neurologist at Uppsala University in Sweden.

As defined by the Alzheimer's Association, tau is the name of a protein that helps in stabilizing the internal structure of the brain's nerve cells. An abnormal build-up of tau protein in the body can end up in causing interior cells to fall apart and eventually developing Alzheimer's.

"When you get more of that deep sleep and you get the REM sleep in the normal amounts, that improves clearance of abnormal proteins which we think is good," said Mayo Clinic neurologist Dr Donn Dexter, not the study author but a fellow of the American Academy of Neurology.

Earlier studies have also shown that getting deprived of sleep can allow higher tau development and accumulation. Thus that poor sleep can hasten the development of cognitive issues.

Researchers caution that the study is small and inconclusive, and acknowledged they were not able to determine what the increased levels might mean.

"This study raises more questions than answers," agreed Dexter on a concluding note, sharing, "What this is telling us is that we have to dig more deeply. Despite something we do for a third of our lives, we know so little about sleep and we're learning every day, particularly when it comes to sleep and dementia."

Walnuts May Boost Mood in Young Men

Eating walnuts may be key to a happier state-of-mind, say scientists who found that the nuts help improve mood, especially in young men. In this first intervention study in humans, researchers measured the effect of walnut consumption on mood.

"In the past, studies on walnuts have shown beneficial effects on many health outcomes like heart disease, diabetes and obesity," said Peter Pribis, professor at University of New Mexico.

"Our study was different because we focused on cognition, and in this controlled randomised trial (CRT) we measured mood outcomes in males and females," he said.

The participants of the study were 64 students between the ages of 18-25. They represented most ethnic groups - Caucasian, African American, Hispanic and Asian.

The participants were asked to eat three slices of banana bread every day for sixteen weeks—eight weeks of banana bread with walnuts and eight weeks of banana bread without walnuts.

The nuts were finely ground into the dough so the two banana breads were similar in taste and appearance. While eating banana bread with walnuts the participants consumed half a cup of walnuts daily.

The mood of the students was measured at the end of each eight-week period.

"We used a validated questionnaire called Profiles of Mood States (POMS)," said Pribis.

"It is one of the most widely used and accepted mood scales in studies on cognition," he said.

"The test has six mood domains: tension, depression, anger, fatigue, vigor, confusion and also provides a Total Mood Disturbance score (TMD). The lower the TMD score the better the mood," he added.

In this double-blind, randomised, placebo controlled, cross-over feeding trial with walnuts for eight weeks, Pribis observed a significant improvement in mood in young, healthy males.

"There was a meaningful, 28 per cent improvement of mood in young men," said Pribis.

"However we did not observe any improvement of mood in females," he said.

There are several nutrients in walnuts that could be responsible for the improved mood like alpha-Linolenic acid, vitamin E, folate, polyphenols or melatonin.

However, this was a whole food study, so in the end it was the synergy and interaction of all the nutrients in the walnuts combined.

"Walnuts not only good for your mood, but overall health as well. The recommended amount is one handful per day," Primis said.
