New studies link poor sleep, OSA in the elderly to increased Dementia risks

A new study by the Pacific Health Research and Education Institute in Honolulu has found that elderly patients who spend less time in deep ‘slow wave’ sleep are significantly more likely to lose brain cells than those who sleep more deeply. The research also showed that the lack of oxygen caused by obstructive sleep apnea, a common condition marked by snoring, increases the risk of the small areas of brain damage linked to the development of conditions such as Alzheimer’s. Researchers say that it is not yet clear whether the early stages of dementia are causing poor sleep quality, or if the lack of deep wave sleep is exacerbating the disease process.

The study, published in the online edition of the journal Neurology, involved 167 Japanese American men from Hawaii with an average age of 84 who had sleep tests conducted at their homes. After death, post mortem examinations were conducted on their brains to look for changes such as loss of neurons and ‘micro infarcts’ - areas of dead tissue caused by oxygen starvation. These can be triggered by obstructive sleep apnea (OSA); a condition in which the airway repeatedly becomes blocked, often waking sufferers as they struggle for breath.

The men who had the worst oxygen levels during sleep were four times more likely to have brain damage caused by micro infarcts. Of the 37 men who spent the least time in slow wave sleep, 17 had brain cell loss compared with only seven of the 38 who spent the most time in slow wave sleep. The results remained the same after accounting for factors such as smoking and body weight, and excluding those who died early in the follow-up period. However, the study found no association between poor sleep and the brain plaques  that are a hallmark of Alzheimer’s disease.

Researchers say that the findings suggest that low blood oxygen levels and reduced slow wave sleep may contribute to the processes that lead to cognitive decline and dementia. More research is needed to determine how slow wave sleep may play a restorative role in brain function and whether preventing low blood oxygen levels may reduce the risk of dementia.

A separate study earlier this week showed that brains of healthy people who were sleepy during the day contained higher levels of a toxic protein called beta-amyloid, which is also linked to Alzheimer’s: some of those having scans were as young as 50 and none had memory problems.

A good night’s sleep is important for proper brain function in the short term. For more information on the treatment of OSA and snoring, visit us online at HoustonSleep.net

Don't let Snoring Break Your Heart!

For years people have thought of snoring as nothing more than a simple annoyance during the night: snoring is so common that we do not view it as a medical problem. Recent statistics suggest that this seemingly simple noise problem may in fact increase the risk of high blood pressure, stroke, heart attack, and daytime sleepiness.

Snoring typically occurs when the tongue and throat muscles relax during sleep causing the airway space in the back of the throat to narrow. Breathing through a narrow airway causes a vacuum that pulls on the throat's soft tissue causing it to vibrate, which creates the snoring sound. This vacuum in the throat also spreads to the chest where the heart is located, causing a strain on the heart and the possibility for oxygen in the bloodstream to drop to dangerously low levels. When these factors occur night after night, year after year, they instigate the problems listed above. Additionally, new studies have also shown OSA causes increased insulin resistance resulting in poorly controlled diabetes.
Studies have demonstrated that in many people, snoring can cause an increase in chest pressures which can influence blood flow in the heart and lungs. This may be the cause of some of the medical problems in people who snore.

CSMA's sleep centers throughout Greater Houston provide treatment to patients sufferering from snoring and obstructive sleep apnea disorders. For more information on how to stop snoring and obtain help for sleep apnea call us today at (281) 407-6222.

Many people who snore have another problem known as sleep apnea. Apnea is a Greek word, which means, "want to breathe." People with obstructive sleep apnea have pauses in their breathing while asleep. These pauses in breathing occur when the airway collapses during sleep. After a few seconds the person briefly awakens, frequently producing a grunting, gasping, or snorting sound.
Obstructive sleep apnea is more common in obese people and more common in men, but it is not just obesity that can cause this problem. People with a small jaw, large tongue, or large tonsils are at higher risk of having this problem as well. In fact, any condition which can narrow the opening in the back of the throat or possibly the nasal passages can increase the risk of obstructive sleep apnea.
It is important to know the consequences of this problem if left untreated. Some of the more common problems associated with obstructive sleep apnea are excessive daytime sleepiness and an increased risk of high blood pressure, heart attacks and stroke.

What can someone do if they want to know if they have Sleep Apnea?

See your physician and ask about being referred to a sleep disorders center. This is a special testing facility that evaluates people for sleeping problems. If your doctor does not feel this is necessary, don't be discouraged. Most physicians have not been taught very much about sleep medicine in medical school and therefore may not recognize this problem in their patients. Be persistent. You can be seen by a sleep specialist and, if needed, a sleep study can be performed on you during the night.

What can be done if a person snores or has Sleep Apnea?

The most effective treatment to date for sleep apnea is called nasal CPAP (Continuous Positive Airway Pressure). An individual wears a mask on their nose at night that administers air pressure, keeping the upper airway open. This allows the individual to breathe throughout the night without repetitive awakenings. If a person only snores and does not suffer from excessive daytime sleepiness, then CPAP is not the appropriate treatment.
Dental appliances have been used for snoring. Sometimes these devices can also prevent apnea as well. Studies have demonstrated that dental appliances work for snoring and sleep apnea, but not in all patients. Surgery has been used to treat these problems. The most frequently performed surgery is a procedure where the soft tissue in the back of the throat including the uvula is cut away or reduced in size with a new microwave needle or a laser. Although this may work well for snoring, unfortunately most patients who have sleep apnea are not adequately treated with these procedures. There are other more extensive surgeries that can be performed for sleep apnea.

A sleep specialist who is very familiar with these procedures should explain them to you. If you snore at night and think you might have sleep apnea, contact your doctor. If your doctor is not familiar with this type of problem, have him or her contact us directly.
