Disrupted sleep could increase risk of Alzheimer’s disease

Recent research has shown the importance of sleep for a variety of health reasons, but new research is showing that lack of sleep or waking up several times during the night may increase your chances of developing Alzheimer’s.

Alzheimer’s disease is a type of dementia that creates issues with thinking, behavior and memory. A sticky plaque called beta-amyloid builds up in the spaces between the nerve cells, causing toxicity in the brain. A study in the journal JAMA Neurology has discovered that disrupted sleep can actually increase this plaque in the brain.

Subjects over the age of 70 were studied as part of the Baltimore Longitudinal Study of Aging. Those who reported getting the least amount of sleep (less than five hours per night) and those who reported experiencing waking multiple times during the night were discovered to have more beta-amyloid plaque buildup once imaging scans were performed of their brains. This increased buildup could be a key indicator for Alzheimer’s disease risk.

Sleep studies have also discovered that those with sleep apnea (a sleep disorder that is characterized by pausing in breathing during sleep) have double the risk of developing Alzheimer’s disease.

The good news is that troubled sleep or trouble staying asleep (also known as sleep maintenance insomnia) is treatable, and this new information could be vital in protecting seniors’ brains. The average adult should be getting seven to eight hours of sleep per night. It is well known that troubled sleep causes difficulties in focus and learning the following day, and we are coming to find out this could be related to dying brain cells.

This importance of this work lies in overwhelming amount of expected Alzheimer’s cases to develop in the coming years as the baby boomer generation will be approaching their 70’s. More than 5 million Americans have already been diagnosed with Alzheimer’s disease, and that number is expected to climb to more than double in the United States by the year 2050, and according to the World Health Organization, more than triple globally, reaching an estimated 115.4 million cases.

Another smoking negative: earlier menopause

One in five women in Los Angeles smoke, according to the Los Angeles County Department of Public Health. A new study, published September 18 in the journal menopause, adds another reason that smoking impacts a woman’s health: earlier menopause. Study author Dr. Volodymyr Dvornyk, from the University of Hong Kong, noted that women “should be aware of this effect and possible health consequences” of smoking, in addition to its other known risks. He and his research team conducted a meta-analysis, which pooled data from six studies of approximately 6,000 women in the U.S., Poland, Turkey, and Iran. It revealed that women who smoke may enter menopause about a year earlier than nonsmokers. On the average, non-smokers reached the menopause between age 46 and 51, on average, depending on the study population. In all but two of the studies, smokers were younger: between age 43 and 50. The researchers also reviewed five other studies that used a cut-off age of 50 or 51 to stratify women into “early” and “late” menopause groups. Among the more than 43,000 women in that analysis, smokers were 43% more likely than nonsmokers to have early menopause. They wrote, “Our results give further evidence that smoking is significantly associated with earlier [age at menopause] and provide yet another justification for women to avoid this habit.”

Dr. Dvornyk noted that the “general consensus is that earlier menopause is likely to be associated with the larger number and higher risk of postmenopausal health problems, such as osteoporosis, cardiovascular diseases, diabetes mellitus, obesity, Alzheimer’s disease, and the others.” He added that early menopause is also thought to slightly increase a woman’s risk of death in the years following. Two theories regarding smoking and early menopause are (1) Smoking may alter the way a women’s body produces or removes estrogen; and (2) Certain components of cigarette smoke might kill ova (eggs). Dr. Dvornyk and his colleagues did not have information on how long women had been smoking or how many cigarettes they smoked each day; therefore, they could not determine how either of those factors may have affected age at menopause.

In addition to the foregoing health effects of smoking are cosmetic issues. Smoking increases facial wrinkles, stains your teeth, makes your voice hoarse, and gives you bad breath.
