Studies show that obstructive sleep apnea (OSA) affects much more than just your sleep. It can even damage your brain.
A recent brain imaging study from France involved 16 adults. Each of them had just been diagnosed with sleep apnea.
In numerous brain regions the study found a loss of “gray matter.” This is brain tissue that contains fibers and nerve cell bodies. There also was a decrease in brain metabolism.
The authors suggest that these changes may explain some of the impairments that often occur in people with sleep apnea. Examples include attention lapses and memory loss. The study was published in March 2009 issue of the Journal of Sleep Research.
The results are similar to those found by a research team from UCLA. Their study was published in Neuroscience Letters in June 2008. They reported that people with sleep apnea have tissue loss in the “mammillary bodies.” These are brain regions that help store memory.
In July 2008 the UCLA team published another brain imaging study in the journal Sleep.It involved 41 people with moderate to severe sleep apnea. It also included 69 control subjects matched by age.
Results show that people with sleep apnea have extensive alterations in “white matter.” This is nerve tissue in the brain. It contains fibers that are insulated with myelin -a white, fatty sheath. The structural changes appear in brain regions that help control mood and memory. These regions also play a role in adjusting your blood pressure. Damage also was found in fiber pathways that connect these brain regions.
What causes the brain damage? The authors suggest that oxygen, blood flow and blood pressure may be involved. Sleep apnea involves breathing pauses that can occur hundreds of times a night of sleep. These pauses can produce drastic changes in oxygen levels.
These breathing pauses also reduce blood flow in the brain. People with sleep apnea also are at risk for high blood pressure. Both of these conditions create a potential for brain tissue damage.
Dr. Ronald Harper of UCLA said that the studies show how important it is for sleep apnea to be treated. CPAP is the most common treatment for sleep apnea. The findings make it all the more imperative that OSA be treated as soon as possible to prevent further injury. The long-term effects of OSA are terribly damaging to memory and thinking processes.
Can treatment reverse the brain damage caused by sleep apnea? The authors are uncertain if the changes are permanent.
But studies show that CPAP does help your heart, it may even save your life.
Insomnia can make you feel like your mind is racing out of control. A revealing new study explains why your brain may be unable to put the brakes on your thoughts. It links the problem to low levels of a brain chemical.
A new study shows that GABA levels are reduced by 30 percent in adults with chronic primary insomnia. The study was published in the Nov. 1 issue of the journal Sleep.
GABA is reduced in the brain of individuals with insomnia, suggesting over activity is present. It was explained that low GABA levels create an imbalance of brain activity. This may lead to an inability to shut down waking signals in the brain.
If your GABA levels are low, then your mind can’t slow down. It may race forward at full speed even when it is time to sleep. An over active mind is a key feature of psychophsicological insomnia. At bedtime you are unable to stop thinking and worrying. Your body may be ready for sleep, but your mind remains alert. This state of “hyperarousal” can make it hard for you to fall asleep.
Most with insomnia have “secondary” insomnia. It occurs along with another medical problem, mental illness or sleep disorder. It also may result from the use of a medication or substance. In contrast primary insomnia is unrelated to another health problem. Estimates that about 25 percent of people with insomnia have primary insomnia. The study only links low GABA levels to long lasting, primary insomnia.
All participants in the study had been suffering from primary insomnia for mor than six months. The average duration of their symptoms was about 10 years. The GABA connection affirms that primary insomnia is a legitimate disorder.
Recognition that insomnia has manifestations in the brain may increase the legitimacy of those who have insomnia and report substantial daytime consequences. It was also explained that insomnia can affect your energy, concentration and mood. It also increases your risk of depression.
One solution for the problem of primary insomnia is the use of hypnotic medication. The short-term use of a sleeping pill can help break the cycle of sleepless nights. The study notes that many of the most effective sleeping pills increase activity at the GABA neurons.
Another treatment option is cognitive behavioral therapy. CBT helps you learn how to correct attitudes and habits that hinder your sleep. Many of these bad habits develop as people try to cope with chronic insomnia.
When you’re feeling stressed on the job, it can be hard to leave work at the office. Your job may preoccupy your mind as you drive, as you eat, and as you interact with family or friends. But the battle to control your mind can intensify when you try to go to sleep.
Sleep and stress are competitors. When stress continually activating a part of the brain that is otherwised used for sleep, then stress wins the tug-of-war.
According the AASM, job stress can be a cause of adjustment insomnia. This involves disturbed sleep or sleeplessness that may last for a few days or a few weeks. Other symptoms may include anxiety, worry and tension.
A common feature of adjustment insomnia is “ruminative thoughts.” This is when you dwell on the same thoughts, chewing them over and over in your mind. You may lie in bed staring at the ceiling, unable to stop thinking about work. Even when you finally fall asleep, your work may invade your dreams. The Staples National Small-Business Survey polled 302 owners and executives of small businesses, and more than half said they dream about work -or “sleepwork.”
Scientific research confirms that job stress can affect your sleep. In 2005 a study in the journal Sleep involved 8,770 Japanese workers. In both men and women, a high level of stress at work was liked to insomnia.
A 2007 study in the International Journal of Behavioral Medicine linked insomnia to these three types of job stressors:
- High work demand
- Low influence over decisions
- High professional compromise
The type of job stress you experience may affect your sleep in different ways. Another study linked work overload to poor sleep quality. Having role conflicts at work was related to non-restorative sleep and trouble falling asleeo or staying asleep.
According to the National Institute for Occupational Safety and Health, sleep disturbances are one early warning sign of job stress. Others may include:
- Difficulty concentrating
- Short temper
- Upset stomach
- Job dissatisfaction
- Low morale
Job stress may be unavoidable. But sleep specialists say you can take steps to improve your sleep even when you are stressed. Establishing a pattern of relaxing behaviors close to bedtime and limiting work to the early evening may help to reduce stress.
Here are jus a few more tips to help you be less restless with work worries:
- Remain active
Try to get some exervise every day. Both your mind and body will be more relaxed when its bedtime.
- Express yourself
Take some time to slow down before going to bed. Get away from the computer, turn off the TV and the cell phone, and relax quietly for 15 to 30 minutes. Take a warm bath, enjoy a light snack or listen to some soft music.
- Avoid “bedwork”
Never bring any work to bed with you; your bed should be refuge from your job. Also avoid doing other activities in bed such as reading, watching TV or talking on the phone. Only use your bed for sleep.
- Get out of bed
If you have trouble falling asleep, get out of bed and do something relaxing until you feel sleep agian. Tossing and turning will only increase your frustrations.
- See a specialist
Some doctors are specialists in behavioral sleep medicine. They can teach you how to relax at bedtime so you can fall asleep more easily.
Current economic conditions in the U.S. are forcing many consumers to cut back on health care expenses. Yet sleep experts advise that the cost of a sleep study is a sound investment for millions of people who suffer from a sleep disorder.
The Centers for Disease Control and Prevention reports that about 15 million adults in the U.S. did not receive needed medical care in 2005 because they could not afford it. In July, the National Association of Insurance Commissioners conduted a national survey. Results show that 22 percent of people have reduced the number of times they visit the doctor because to current economic conditions.
In such a challenging economy, should your sleep needs be a priority?
Sleep is one of the cornerstones of good health. It affects everything from your weight and blood pressure to your energy and mood. If you have been struggling with an ongoing sleep problem, then a sleep study may be just what you need. It could be the key that unlocks the door to a dramatic improvement in your health and a better quality of life for you.
Losing sleep over the economy, but losing sleep over an undiagnosed problem is no fun.
People are notorious for underestimating how sleepy they are. People assume that thier disrupted sleep and level of sleepiness when awake is normal for their age. Symptoms of some sleep disorders also can go unnoticed. For example loud snoring and gasping for breath durning sleep are two warning signs for sleep apnea. But you may be unaware of these sym if you live or sleep alone. As a result, millions of people go through each day wondering why they can’t stay awake. Others go to bed each night wondering why they can’t sleep. The answers to these questions often can be found by a sleep study…
Here are some benefits to think about:
Research shows that there are numerous benefits to detecing a sleep disorder with a sleep study. The study pinpoints the nature and cause of your sleep problem. This provides the foundation for an effective treatment plan. Treating a sleep disorder promotes heath, productivity and well-being. In the long run it also can save you money!
- Improved Health
Research has linked sleep disorders to many other health problems. These include heart disease, high blood pressure, stroke, diabetes and obesity. A study in the journal Sleep even shows that people with severe, untreated sleep apnea have five times the risk of dying from a heart problem. Effective treatment of a sleep disorder can reduce the risk and severity of other related health challenges.
- Reduced Spending
Studies have linked undetected and untreated sleep disorders to an increase in health-care utilization and spending. You are likely to make more visits to the doctor’s office each year. You are also likely to spend more money on your health care. Expenses may include testing, medications and hospitalization. Research shows that effective treatment of a sleep disorder can reduce your health-care spending. Compared to the high cost of remaining untreated, treating most sleep disorders is relative inexpensive.
- Greater Productivity
Studies have linked sleep disorders to lower productivity and more absences at work. A severe sleep disorder may even prevent you from being able to stay employed. Effective treatments of a sleep disorder can enable you to improve your job performance.
- Better Safety
Research has linked sleep disorders to an increased risk of work-related injuries and motor-vehicle accidents. Effective treatments promotes your safety at work on the roads.
- Improved Quality of Life
Sleep disorders can take a severe tool on your personal well-being. Taking care of yourself leads to improvements in your mood, attitude, energy, memory and overall outlook on life. Sleep disturbances can put strain on your relationships.

Bad Sleep Habits: it involves the things that you do normally everyday. Although, these habits keep your sleep from being refreshing. They can also keep you from feeling alert during the day. These activities are all the things that you should be able to control. These specific behaviors fall into the follow two general categories:
1. Practices that keep you awake.
2. Practices that bring disorder to your sleep schedule
Many common factors may keep you awake at night. At first, alcohol may make you sleepy; but it is also more likely to wake you up during the night. Drinking coffee or colas that contain caffeine can make you more alert. The nicotine ina cigarette can have the same effect. People often use these substances to “keep their edge” during the day. This “edge” is not always gone by the time they try to go to sleep.
Other factors that cause you to stay awake when they occure too close to bedtime include the following:
- Mental stress
- Physical exercise
Many other practices can keep you from having a regular pattern of sleeping and waking up. Perhaps you are unable to fall asleep because you spend too much time in bed. Maybe you don’t go to bed and wake up at the same times everyday. Or maybe you nap too often, too long, or too close to your bedtime. These bad habits can confuse your body. This will cause you to stay awake when you should really be asleep.
You can be affected in the followig negative ways:
- Mood changes
- Short attention span
- Poor concentration
- Daytime sleepiness
- Frustration with sleeping
- Caffeine dependence
- Alcohol abuse or dependence
It may often be obvious to other people around you that the things your are doing are hurting your sleep. You, however, may be completely unaware of it. You may also find that your sleep problems tend to come and go. This is because you are likely to change your sleep habits over time.
Who gets it?
It is typically not found in younge children. It may develop though, as early as the teen years.
It may also begin at anytime throughout adulthood. The timing of when it begins depends on when the habits that distrurb sleep are developed. The rate at which it affects males and females differently is not known.
How do I know if I have it?
First, you need to determine if you have insomnia:
- Do you have trouble falling asleep, staying asleep, waking up too early, or not feeling refreshed after sleeping?
- For a child, does the child resist going to sleep or sleeping alone?
- Does this problem occur even though you have the opportunity and the time to get a good night’s sleep?
- Dout have at least one of the following problems? You have:
- Low energy
- Lack of motivation
- Attention, concentration or memory problems
- Poor performances at school or work
- Extreme mood changes
- Daytime sleepiness
- Trouble making errors at work or while driving
- Tension, headaches or stomach aches
- Frustration or worry about your sleep
If your answer to each of these questions is yes, then you might have insomnia. Now continue to see if you might have inadequate sleep hygiene”
- Have you had these problems for at least one month?
- Do you you have at least one of the following bad habits?
- You have a bad sleep schedule. You nap a lot, go to bed and wake up at different times everyday, or spend too much time in bed.
- You often use products with alcohol, nicotine, or caffeine near bedtime
- You actively do things that excite your mind, body, or emotions near bedtime.
- You often use the bed to do things other than sleep. This includes paying bills, talking on the phone and eating.
- You do not keep a comfortable sleeping environment. Research shows that having your bedroom slightly cooler ( via a cieling fan and the slight noise of the fan) are helpful. Low dim lighting such as nightlights are requested, and lavender sented candles can help soothe you into a good sleep regimen.
If you also answered yes to these questions, then you may have inadequate sleep hygiene.
It is also important to know if there is something else that is causing your sleep problems. They may be a result of one of the following:
- Another sleep disorder
- A medical condition
- Medication use
- A mental health disorder
- Substance abuse
Do I need to see a sleep specialist?
Talk with a family doctor about your difficulty sleeping. See if you are able to correct the bad sleep habits that are affecting your sleep. Are you having a hard time improving your habits? Or are you still having a sleep problem even after making these changes? If so, then you made need to see a sleep specialist.
What will the doctor need to know?
First, the doctor will need to know when your insomnia started. He or she will also want to know what else has been going on in your life. The doctor will need to know about any other medical problems you have today or had in the past. Be sure to tell the doctor if you are taking any medications.
Keep a sleep dieary for two weeks. The sleep diary will help the doctor see your sleeping patterns. The sleep diary information gives the doctor clues about what is causing your problem and how to correct it.
Will I need to take any test?
Doctors do not need any tests to treat most insomnia patients. A sleep specialists may give you a written test to analyze your mental and emotional well-being. The specialist may need to test your blood in the lab if he or she thinks that you have a related medical problem.
How is it treated?
Many cases of insomnia will respond to changes that you can make on your own. You can often sleep better by simply following the practices of good sleep hygiene.
Sleep hygiene consists of basic habits and tips that help you develop a pattern of healthy sleep. There are also easy ways to make your bed and bedroom more comfortable.
You need to seek help from a therapist if stress or depression is the cause of your sleep problems.
When self-treatment does not work, a doctor can provide help. Doctors can teach you different ways to improve your sleep. An example of this is to use relaxation exercises when you go to bed. They can also help you find ways to take your mind off of sleep. Staying out of bed until you are tired is a good way to start off slowly. These methods are a part of what is known as behavioral therapy. With slow changes, you will see the biggest change at the end, feeling refreshed and happy.
Are you satisfied with your life? If not, how’s your sleep? A new study shows there may be a connection.
Life satisfaction and sleep quality are known to be important factors in your overall health and well-being. But how are they related?
Does poor sleep cause you to be less satisfied with your life? Or does low satisfaction with your life lead to sleep problems?
The researchers sought to find the an answer. Their study involved 18,631 same-sex twins in Finland.
They measured life satisfaction, sleep quality and other factors. Then they did a follow up six years later and recorded the same measures.
What did they find? People who became dissatisfied with their life during the six years between study points were more likely to have had sleep problems. Fifty-nine pecent of these newly dissatified people had reported at the beginning of the styd that they sleep poorly.
The results also show that poor sleep predicted a consistent pattern of life dissatifaction. But the reverse wasn’t true; life dissatisfaction did not consistently predict poor sleep.
Studying twins also provided a genetic look at the connection. The study shows that both sleep quality and life satisfaction has a strong genetic component; there was substantial heritability for both traits.
Both genetic influence is different; the genetic component shared by sleep quality and lif satisfaction was relatively weak.
The study supports the idea that poor sleep may have direct effects on the brain, emotions and mood.
So how is the quality of your sleep? You can get a better idea by completing this brief sleep evaluation.
