    Bad Sleep = 2 Years of Aging

    July 19th, 2012 by DrLowrance | ShareThis

    Two years off your life doesn’t seem like such a big deal now but at 65, you begin to think about those things. Every day counts.

    At the recent Alzheimer’s International Association Meeting in British Columbia, a series of reports and studies were presented that showed a high correlation between poor sleep quality, excessive daytime sleepiness, shift working and dementia or cognitive decline. They based this on the Nurse’s Health Study which involved 15,000 nurses.

    They reported that women who slept 5 hours and less or over 9 hours had and increased risk of dementia compared with women who slept 7 to 8 hours. The 9 hours or more of sleep and increased dementia could be related to poor sleep quality that kept people in bed longer as they tried to make up for the poor sleep patterns.

    Other studies have shown that Alzheimer’s patients improve in their cognitive performance and rate of decline if sleep issues such as sleep apnea are treated. Dementia is not only related to quality of sleep but oxygen too.

    These results were underscored by a French study that showed that people with excessive daytime sleepiness (tired all the time) are much more likely to have memory loss and increased risk of Alzheimer’s.

    Whether it is dementia, cognitive decline or Alzheimer’s, good breathing while sleeping is very important. It affects the quality of your sleep and long-term health.

    These things are easily treated with a dental oral devices that open the airway and complete a good flow of oxygen to the brain and other organs. In the near future, treatment and prevention of chronic diseases will be heavily connected to treating sleep problems.

    Combination CPAP and Oral Device

    May 21st, 2012 by DrLowrance | ShareThis

    CPAP machines are the gold standard for treating sleep apnea. They have by far the greatest amount of research behind them. They do work well but they have several draw backs.

      1. They have to be cleaned daily. If you don’t clean and disinfect them, they promote lung and sinus infections.
      2. They tether you to a bed. You cannot get up and wander around at night without disconnecting yourself from the CPAP.
      3. They require you to sleep on your back. You have no choice in this.
      4. They forcefully push air into your throat past the apnea blockage.

    That last one may be the biggest drawback especially if the pressure is set very high on the CPAP. This is where wearing an oral appliance can help. With the benefit of an oral appliance, the pressure can be significantly lowered making the CPAP more comfortable and easier to wear.

    Sleep Apnea makes you FAT

    Sleep Apnea and Getting Fat

    Sounds fishy but there is a HUGE correlation between the two. Actually you don’t have to have Sleep Apnea (OSA) to have increase weight gain; all you need to have is to loss of sleep.

    A normal night’s rest is between 7 and 8 hours for a adult. That is different from a child, teenager or senior citizen. Loss of 30 minutes of sleep per night is enough to cause Sleep Deprivation and when that happens all sorts of bad biochemical, physiological and psychological things happen. None of this is good.

    A recent article by Dr Mark Hyman describes how loss of sleep will “make you fat” and that leads to depression, pain, heart diseae, diabetes and strokes. He got my attention with the last one—strokes.

    As Dr Hyman explains, sleep apnea is where your sleep is interrupted at night because your airway closes. That event “startles” your body so you won’t suffocate. Have you ever been startled at night? Remember what happens? You wake up frightened! You feel your heart beating fast. You are alarmed that something is wrong. This can happen many times a night for someone with sleep apnea and it causes sleep deprivation even IF you don’t fully wake up. It keeps you from getting deep, restful, restorative sleep.

    This condition affects 18 million Americans and only 10% are being treated for it. You could be one of those.

    You can lose sleep from Sleep Apnea but you can also lose sleep from staying up too late watching TV or playing/working on the computer or, it could be job related such as “shift workers” experience.

    There are many things that can disrupt your Essential Sleep and lead to weight gain and getting FAT.

    Please read Dr Hyman’s article for his 19 Tips on Getting a Good night’s sleep and getting healthy.

    If you want personal, quality care then I suggest you find a dentist who focuses on treating Sleep Apnea.

    ADHD could be Sleep Apnea

    April 30th, 2012 by DrLowrance | ShareThis

    Attention Deficit Problems May be Sleep Related.

    ADHD (Attention Deficit Hyperactivity Disorder) diagnosis has increased dramatically in recent years (up 22% between 2003 and 2007 alone). This was reported by the CDC (Centers for Disease Control and Prevention). However, many experts believe that this may be overlooked Sleep Disordered Breathing like Sleep Apnea. The symptoms are very similar. Children often become wired, moody and obstinate. They may have trouble focusing, sitting still and getting along with peers.

    If this is the case, then for many misdiagnosed children, the drugs used to treat the disorder my be exacerbating the problem, making the children harder to manage.

    I am not saying ADHD doses not exist but we do need to be careful to rule out Sleep Related Breathing Disorders like Sleep Apnea before we prescribe medications for ADHD. In one recent lecture I attended, the parents of a normal looking 11 year old told about how they spent 8 years and $22,000 treating ADHD when it was Sleep Apnea. A dentist discovered this by just noting the dark circles under his eyes and his huge tonsils. The parents thought his snoring was just “deep sleeping”.

    Children have a very low tolerance for loss of good sleep. As little as 30 min. loss of needed sleep per night can quickly lead to ADHD like symptoms, and the drugs to treat ADHD (Ritalin, Adderall or Concerta) can cause insomnia. Treatment can become a vicious, compounding cycle.

    If you want personal, quality care then I suggest you find a dentist who focuses on treating Sleep Apnea.

    Why should a dentist treat Sleep Apnea and Snoring?

    April 18th, 2012 by DrLowrance | ShareThis

    That is a valid question and one that I get asked on a regular basis.  Aren’t dentist supposed to be just concerned with teeth?

    If you have a minute, I will run through the many reasons why dentist should treat Sleep Apnea and snoring.

    1.  The present system of Sleep Laboratories and CPAP Providers (DMEs) is broken.  Anyone who has ever been given a CPAP after an overnight sleep study knows what I am talking about.  How much explanation did you get on use of your CPAP?   How much help did you get in fitting a mask?  Did they follow up with you by having you come in on a regular basis and check the CPAP and see how you were doing in wearing it?  Where is your CPAP now?  Did you ever actually see the Sleep Physician?

    2.  Dentists may be primarily concerned with teeth but the teeth are in a major airway.  We routinely check the mouth for airway compromise.  The shape of the dental archs, size of the tongue, height of the hard palate are all indicators of airway adequacy or inadequacy.  We “LOOK”!  Did your Sleep Laboratory or DME provider LOOK?  Probably not. In fact, my primary care physician has never looked in my mouth or asked me how was my sleep. Has yours asked you?

    3.  We routinely have patients on a 6 month recall to check and clean their teeth.  We know how to do that.  It is easy to add Sleep Apnea patients a recall and check their appliances or CPAP and mask.  How else are we going to be able to help you?

    If you want personal, quality care then I suggest you find a dentist who focuses on treating Sleep Apnea.
