One in two hypertensive pregnant women who habitually snore may have unrecognized obstructive sleep apnea, a sleeping disorder that can reduce blood oxygen levels during the night and that has been linked to serious health conditions, new University of Michigan-led research shows.

One in four hypertensive  who don’t snore also unknowingly suffer from the, according to the study that appears in the British Journal of Obstetrics and Gynecology.

“We know that habitual snoring is linked with poor pregnancy outcomes for both mother and child, including increased risk of C-sections and smaller babies,” says lead author Louise O’Brien, Ph.D., M.S., associate professor at U-M’s Sleep Disorders Center in the Department of Neurology and adjunct associate professor in the Department of Obstetrics & Gynecology at the U-M Medical School.

If you’ve ever counted sheep, woken up multiple times during the night or experience daytime sleepiness, you are one of the 67 percent of older adults who suffer from insomnia symptoms at least a few nights a week, according to the National Sleep Foundation. As we age, sleeplessness may become more of an issue, so we’ve rounded up the top causes of insomnia for older adults.

  • Cause #1: Circadian Rhythm
    Aging causes our circadian rhythms to change and become less consistent, which makes us more susceptible to insomnia, according to the National Institutes of Health. We become sleepy earlier in the evening and wake up earlier in the morning. When we try to fight our body’s natural instincts by attempting to stay awake or sleep later, it often becomes a losing battle.

Not Getting Enough Sleep May Contribute to Mental Decline in Later Years

Chronic sleep deprivation and poor sleep quality have been linked to a number of health problems, but now a new study has identified one more potential risk, namely cognitive decline at old age, including Alzheimer’s disease (AD).

While it has not been determined yet whether people who don’t sleep well are more likely to suffer from dementia as they get older, or whether it is a symptom of mental illness already on its way, scientists have long known that both sleep hygiene and mental well-being are closely connected.

For the study, the researchers scanned the brains of 70 participants, ages 53 to 91, looking for clusters of beta-amyloid plaques, proteins that when building up in the brain may cause the kind of damage associated with AD.

This is not the first time scientists have investigated the role of sleep, or lack thereof, for mental health.

Nocturnal Teeth Grinding May Suggest a Sleep Disorder

The occurrence of gnashing or grinding of teeth is not new. The Bible makes reference to this phenomenon both in the Old Testament, “His anger has torn me and hunted me down; he has gnashed at me with his teeth,” (Job 16:9) and in the New Testament, “But the children of the kingdom shall be cast out into outer darkness: there shall be weeping and gnashing of teeth” (Matthew 8:12). While this problem is many centuries old, it is only recently that we have come to understand why this may occur, particularly at night while we are asleep.

Teeth clenching or grinding — a behavior known as bruxism — is a common problem that can lead to broken teeth, enamel damage, headaches, and temporomandibular joint (TMJ) disorders. The term “bruxism” comes from the Greek word “brychein,” which means “to grind or gnash the opposing rows of upper and lower teeth.” The American Academy of Orofacial Pain defines bruxism as “diurnal or nocturnal parafunctional activity which includes clenching, gnashing, gritting and grinding of teeth.” Data on the prevalence of bruxism varies based upon research criteria, working definition, population samples, and clinical criteria.

Sleep apnea bill awakens Congress

Sleep apnea bill awakens Congress
By ADAM SNIDER | 9/24/13 5:00 AM EDT

The tale of a sleep apnea bill shows what just might be the most efficient Congress has been in years.

In a few short weeks, two House members went from writing a simple two-page bill to seeing the Federal Motor Carrier Safety Administration committing to a formal rule making on sleep apnea testing and treatment for truckers and other professional drivers.

Along the way, Reps. Larry Bucshon (R-Ind.) and Daniel Lipinski (D-Ill.) secured the support of major industry groups and dozens of their House colleagues. The House Transportation and Infrastructure Committee unanimously passed their bill Thursday, just a week after it was introduced. It’s slated for a House vote Wednesday, just 13 days after introduction. That success aside, what they most wanted was for FMCSA to go on record in favor of a rule making — and that’s just what they got.

“A lot of times in Washington, D.C., if you get both political parties to agree on something that’s very practical, you can move things more quickly,” Bucshon said in an interview.

New Way to Detect Sleep-Disordered Breathing in Children

Sep 20, 2013

BARCELONA, Spain — A new test for detecting sleep-disordered breathing in children could put an end to cumbersome and expensive overnight sleep studies, researchers report.

Sleep-disordered breathing is actually quite common in children, but is often undiagnosed. If left untreated, it can lead to a number of consequences, ranging from primary snoring to complete sleep apnea, which, in some cases, can impair a child’s intellectual and physical development, explained Marcin Kawalski, from the sleep-disordered breathing laboratory at Mościcki Hospital in Chorzów, Poland.

Dr. Kawalski presented the findings here at the European Respiratory Society 2013 Annual Congress.

His research team looked at “pulse transit time as a surrogate measure of night events in children. This method was compared with nocturnal oximetry, heart rate variability, and evaluation of the cortical arousals,” Dr. Kawalski noted.

Pulse transit time is the time it takes the pulse pressure waveform to propagate through a length of the arterial tree.

New Guidelines on Obstructive Sleep Apnea

Doctors should encourage obese patients with obstructive sleep apnea (OSA) to lose weight and recommend continuous positive airway pressure (CPAP) as initial therapy for all patients with OSA, or mandibular advancement devices (MADs) if adverse effects with CPAP occur, according to new clinical guidelines from the American College of Physicians (ACP).

Clinicians “should encourage weight loss in obese patients because obesity is associated with increased risk of OSA, and weight loss may reduce OSA symptoms and has many other health benefits,” write the authors of the guidelines, led by Amir Qaseem, MD, PhD, director of clinical policy at ACP, in Philadelphia, Pennsylvania.

According to the guidelines, published online September 24 in Annals of Internal Medicine, surgery and pharmaceutical therapy are not recommended for patients with OSA.

More than 18 million US adults have sleep apnea, which is a leading cause of excessive daytime sleepiness. The most common type of sleep apnea is OSA, in which the airway collapses or becomes blocked during sleep.

The Association of Obstructive Sleep Apnea and Erectile Dysfunction

Christopher J. Lettieri, MD

Jul 30, 2013

Editor’s Note: Obstructive sleep apnea (OSA) is associated with numerous comorbid conditions. In many, a causative relationship has either been well established or strongly associated. As the knowledge of sleep-disordered breathing and its consequences continues to grow, so does the list of associated or consequential conditions. The following is part 3 of a 5-part series exploring more recently identified consequences of OSA.


Erectile dysfunction (ED) is common in patients with OSA. Sleep apnea induces hormonal alterations, deviations in neural regulation, endothelial dysfunction, and changes in microvascular perfusion that can cause or contribute to the development of ED.

The association of ED and OSA, and the causative nature of OSA in the development of ED, continue to be better defined, and there have been numerous recent publications exploring these relationships. Men with OSA experience more sexual dysfunction and sexual dissatisfaction when compared with age-matched controls.
