Researchers Conduct Sleep Apnea Study

Researchers have been investigating sleep and its effects on the human population for a long time. One of the current focuses is on sleep apnea, a sleep disorder characterized by frequent stops in breathing. Consequences of sleep apnea can be serious, including hypertension, stroke and cardiovascular disease, and currently affects over 18 million Americans. Sleep apnea study, therefore, can benefit a major portion of the population.

The National Sleep Foundation, the American Sleep Apnea Association, and The National Institutes of Health's (NIH) National Institute of Neurological Disorders and Stroke and the National Center on Sleep Disorders Research, are a few organizations who conduct sleep apnea studies. These sleep apnea study researchers not only examine the origin and the effects of the disorder, but other diseases and disorders that can be affected by sleep apnea.

One such sleep apnea study is The National Heart, Lung, and Blood Institute (NHLBI) of NIH's "Sleep Heart Health Study" (SHHS). NHLBI reported in April of 2000 that middle-aged and older adults with sleep apnea showed a 45 percent greater risk of hypertension--a major risk factor for cardiovascular disease. The sleep apnea study involved more than 6,000 adults aged 40 and over, whose sleep apnea was assessed via at home polysomnography (PSG). PSG records body activity during sleep, such as eye movement, heart rate, respiratory effort, airflow and blood oxygen levels. The result: the risk of hypertension increased with the severity of the apnea in all participants, regardless of age, sex, race, or weight. The risk was evident even at moderate levels of sleep apnea.

A different sleep apnea study, conducted by Jana R. Cooke, MD, of the University of California at San Diego, examined patients with both Alzheimer disease and a sleep-related breathing disorder. This study focused on 48 adults, average age 77.8 years, treating them for the sleep disorder with CPAP, continuous positive airway pressure, the most common treatment for sleep apnea. Results: the patients slept more during the night and slept deeper. Since waking episodes are a problem for Alzheimer's patients, improving their sleep, improved their quality of life.

A third sleep apnea study, performed at the St. George Hospital, University of New South Wales in Koragah, Australia, focused on the effectiveness of oral devices to keep the airway open to relieve sleep apnea. The sleep apnea study consisted of 4 weeks of treatment with the MAS, and a control device (an inactive oral appliance). Sleep apnea tests were performed on each patient at the end of each treatment period. Results showed that in 59 men and 14 women of an average age of 48 years, the MAS Therapy improved a range of symptoms associated with sleep apnea. Daytime sleepiness was reduced, as was sleep latency (the time it takes to fall asleep once lights are out.)

These three sleep apnea studies are but a small portion of research projects for sleep apnea. NIH's currently lists over 50 sleep apnea studies on their website as "in progress" or "searching for subjects.

Sleep Study-Sleep Apnea Study Procedure

What to expect on your sleep study

So if you have problems sleeping at night? Or perhaps you are unduly tired during the day? You doctor suggests getting a sleep study report?

While you may be worried about the prospect of sleeping in a strange place with strangers you see, the actual process quite simple. Let us walk you step-by-step through what you can expect from a sleep study.

A sleep study or polysomnogram, is the best way for doctors to discover just why you do not get a good night's sleep. If you have a problem with snoring, restless limbs, Sleepwalking, bed wetting, night terror, insomniaor difficulty sleeping on shift work, a polysomnogram will let doctors see just why you are having problems, and put forward proposals that can help to remedy the problem.

There are five different types of sleep tests:

Diagnostic overnight Polysomnogram

Diagnostic Daytime Sleep Latency Test more

Diagnostic Daytime several Wake Test

Two night Polysomnogram with CPAP titration

Split night Polysomnogram with CPAP titration

Type of test you will receive will depend on the specific issues you are facing.

You get a set of instructions by your doctor in your sleep test. These instructions so that you know how to prepare yourself for your visit. Patients are asked to refrain from drinking or taking any medicine before the test. If you have prescription drugs, you normally take night, bring it with you and ask if it will interfere with the testing. Always let your doctor know exactly what medications you are taking, including herbal medicines and vitamins.

Before heading to your sleep test pack a small overnight bag. You must use your PJs, clothes you plan to wear the following day, toiletries, shampoo and SOAP to shower in the morning and books/magazines/music, you can for entertainment before sleeping. If you are fussy about your pillow, it's a good idea to bring along your own comfort. Make sure that you avoid caffeine or alcohol the day before your test, especially after dinner. It is wise to take a shower before their appointment, but do not use any creams, moisturizers, perfumes and other products, skin. All makeup, Nail Polish and fake nails should be removed, since they can interfere with the equipment.

You may have already been asked to complete a questionnaire before their appointment. If not, you will likely be asked to fill out an when you arrive. This will inform doctors of your regular sleep habits and help them to interpret the results.

On most sleep centers do you have a private suite, which includes a bathroom with shower, and, of course, in the bedroom. There will be a central monitoring station can monitor multiple rooms at once. When you arrive, you get some time to get changed and become comfortable.

When you're ready for bed will hook you up engineers to a number of sensors. These electrodes read a range of information, which is later interpreted by your sleep doctor.

EEG or elektroncefalografi-these electrodes are attached to your head and measuring your brainwaves as you sleep. Different patterns of brainwaves are associated with different stages of sleep. Electromyogram or EMG-measuring these electrodes your muscles reaction, indication of muscle twitches, leg movements and many other typical REM sleep movements. EOG electro-oculogram-these electrodes placed over your face or under the eye to measure the movement of your eyes as you enter REM sleep. ECG or electrocardiogram-a series of electrodes on your chest to monitor your heart. Nasal airflow Sensor-this sensor placed near your nose and mouth for the measurement of the temperature of your breath and your rate of breathing, which registers all periods of irregular breathing. Chest/abdomen Belts-these two belts placed around your chest and abdomen to measure the strength and depth of your breathing. Oximeter-clip is linked to one of your fingers to measure the oxygen content in your blood.

In addition to the sensors attached to them, there are monitors in place for video recording your sleep and record sounds you make as you sleep. After having so many sensors attached seems to be uncomfortable, but most people sleep reasonably well to sleep clinic.

A sleep test is generally finished at 6-7 the next morning. As long as you have a minimum of 6 hours of testing time, most clinics pretty flexible when you need to leave. You do not receive your results immediately after the test. It takes a couple of hours to treat all the information has been collected through the night and then more time for a physician to interpret the results. Most patients hear back from their doctors within a week after the test to be asleep.

A sleep apnea the mouthpiece is an effective way to treat sleep apnea and snoring. Find a sleep apnea treatment plan is very important in living a healthy life.

Sleepless Canadians boozing himself to sleep: study

Canadians are hundreds of millions of dollars each year self medicating their insomnia with alcohol expenditure, suggests a new study.

"We were very surprised to see that so many people use alcohol as a way to sleep, to promote, in particular because there are more negative than positive effects on sleep," says Charles Morin, a professor of Psychology at the University of Laval and one of the authors of the study, published this week in the journal sleep.

Generally, eight percent of the sample reported using alcohol as a sleep aid. In people with insomnia reported 28% self medicating with alcohol.

The study, one of the first in Canada to numbers to the social and economic burden of insomnia, estimates the total annual cost of the sleep disorder in Quebec alone is $ 6.5 billion.

"We know insomnia is a common problem, it has a very negative impact on the quality of life of people," says Morin. "If we can show that it is 10 times more expensive is not for the treatment of insomnia because of its impact on absenteeism from work and reduced productivity than it is to treat it, why aren't we treat it more often?"

Part of the problem is that so few people search help. Morin says: some people take sleeping pills, "but there are many more who self-medicate with over-the-counter products or, worse, with alcohol."

"Why people do that? Is it because they are afraid of using sleeping pills prescribed because of the stigma associated with it, or because they don't know that there are other treatment options available? "

The research found the money spent on the use of spirits, such as a sleep aid is much greater than costs in connection with visits to doctors and the use of prescription pills and OTC-products of antihistamines to herbal tea.

"The idea that schnapps before your bedtime good for your sleep is could correct about 100 years ago, been as long as it was the occasional schnapps," says Dr. Adam Moscovitch, Medical Director of the Canadian sleep Institute and associate clinical professor at the University of Calgary.

"When you knock yourself out as a way of dealing with it, if you don't close off your thoughts in any other way, than alcohol a very negative effect on your sleep. It deprives you of one of the deepest stages of sleep and once it wears off, there is a rebound effect. So your problem is worse. "

Of the 6. USD 5 billion annual cost associated with insomnia in Quebec, the largest indirect costs by far-$ 5 billion-was reduced productivity.

The highest direct cost-$ 339.8 million-was money spent on alcohol to sleep. In comparison, an estimated $ 16.5 million was spent on medicines, and 1.8 million dollars for OTC products.

The study involved Quebec only, but the researchers are doing a similar study throughout Canada. "I expect we'll pretty much the same results," says Morin.

The study, based on a random sample of 948 adults, distinguish between those who at the end of the day drinking, and those who use drink specifically to sleep, which means that they drink before bedtime, or in the middle of the night.

Self medicating with alcohol can lead to other complications, says Moscovitch. "Alcoholism is a large, especially binge drinking." Insomnia can also lead to depression, anxiety disorders and obesity.

The worrying is that insomnia is more and more often, say sleep researchers.

True insomnia is a disruption of the significant sleep for at least a month. People have problems falling asleep, staying asleep, waking up too early or "wake up and feel like you run over by a truck were", says Moscovitch.

According to the study, between six and ten percent of the population meets the diagnostic criteria for full-blown "insomnia syndrome", and about a third symptoms "at any given time."

Canadians are living today in a stressed society with multiple pressure balancing work and family responsibilities. "One of the things that we cut back on is our sleep," says Moscovitch.

For the study, volunteers filled out questionnaires on sleep, health, doctor visits and the time of work and reduced productivity in the past three months. Of a provincial health insurance Board also collected data.

The average age of the volunteers was 44; 60 percent were women and most worked day shifts for full-time jobs.

948 Volunteers, were 493 (52%) classified as "good sleepers," 308 (33%) as symptoms of insomnia and 147 (15 percent) as a syndrome of insomnia.

According to the study was the annual cost of insomnia-related health-care visits an estimated $ 85.3 million

Any person with insomnia is costing society an estimated $ 552 a year in work-related absence and $ 4,154 in reduced productivity due to their sleeping problems.

Australian study shows a direct connection between the weight and the severity of sleep apnea

A study conducted by a sleep clinic in Newcastle has shown that the seriousness of sleep apnea patients was directly related to its weight. After the examination of records of 20 years, it became clear that, as their patients have gained weight and increased your BMI, the frequency of its apnoeas increased.

There has been a link between sleep apnea and overweight, but it is interesting to find a study that shows the relationship between the two so directly. On average men put 10 kg and 12 kg of women when for the first time, they visited the clinic, but while no specific reason was nominated for because they put on weight, increasing the severity of your sleep apnea was a consequence of course.

Weight and sleep apnea are closely linked

Dr Jeffry Pretto, who made the analysis of clinical data, said: "how many times each time people actually stop breathing, or delay your breath significantly-this brand is very attached to the body mass index. How bodyweight people rises, the severity of your sleep apnea gets worse. Another interesting conclusion is the occurrence of severe obesity-that is if they have a body mass index of more than 40. In 1987, only 3 percent of people who were referred to us for sleep studies that we classify as having morbid obesity. In 2007, which was up 15 percent. He is gone by a factor of five. "

Without successful treatment for sleep apnea can become a vicious cycle. Sleep apnea makes you tired during the day, giving it less energy to be active and exercise. This takes you to gain weight, increasing the severity of their apnea, making it even more apathetic. The cycle goes on and on. Some people also blame cravings for carbohydrates increase fatigue, which leads to weight gain.

To break the cycle, you first need to get treatment for sleep apnea. CPAP therapy treatment, the most successful and widely adopted for sleep apnea, will relieve or greatly reduce the frequency of apnoeas, giving you the energy and enthusiasm during the day to allow you to be more active and exercise.

From there, the circle repeats itself in the opposite direction, more energy, more exercise, lose weight, less apnoeas, more energy, etc. It takes determination, perseverance and patience, but by weight loss can reduce the severity of your sleep apnea and, in some cases, inasmuch it completely.

While easier said then done, if you are suffering from sleep apnea, then it is important to try to at least keep your current body weight, if possible, and ideally Look gradually lose weight. One of the biggest problems with sleep apnea is it typically gets diagnosed too late, on average about seven years of suffering, when most people are more than 40 and a lifestyle change becomes very difficult to implement.

One of our Forum members, scourserpaul, started now using the Atkins diet to reduce your weight. You can track your progress on your thread sleep apnea and diet.

Weight loss when you have sleep apnea is far from easy, but it gets easier as you go along as previously mentioned the positive cycle takes effect. The health benefits are not confined only to sleep apnea reduced, so it's certainly worth making a concerted effort to.
