Sleep apnea higher in tetraplegics

• Burns SP, Kapur V, Yin KS and Buhrer R (2001). Factors associated with sleep apnea in men with spinal cord injury: a population-based case-control study. Spinal Cord. 39 (1): 15-22. Summary: OBJECTIVE: To characterize a population of spinal cord injury (SCI) patients with sleep apnea, and to determine associated factors and comorbidities. STUDY DESIGN: Population-based retrospective case- control study. SUBJECTS: 584 male patients served by a Veterans Affairs SCI service. MEASURES: Medical records were reviewed for sleep apnea diagnosis, demographic information, neurologic characteristics, and treatments received. Sleep study reports were not available to determine the nature of abnormal respiratory events (ie central, obstructive, hypoventilation). For each case with tetraplegia, a control tetraplegic subject without sleep apnea diagnosis was selected. RESULTS: We identified 53 subjects with diagnosed sleep apnea: 42 tetraplegic, 11 paraplegic. This represented 14.9% of all tetraplegic and 3.7% of all paraplegic patients in the population (P<0.0001 for comparison of tetraplegic and paraplegic proportions). In tetraplegic subjects, sleep apnea was associated with obesity and more rostral motor level, but not with ASIA Impairment Scale. Medical comorbidities associated with sleep apnea in non-SCI patients, such as hypertension, were more common in case subjects. Less than half of case subjects were receiving some form of treatment. For motor-complete tetraplegics, long- term positive airway pressure treatment was less common with motor level C5 and above compared to C6 and below. CONCLUSION: In this population, sleep apnea has been frequently diagnosed, particularly in tetraplegic subjects. The true prevalence is likely to be considerably higher, since this study considered only previously diagnosed cases. Sleep apnea was associated with obesity and higher neurologic level, but not ASIA Impairment Scale. Medical comorbidities were more frequent in this group, and treatment acceptance was poor with higher level motor-complete injuries. Since the type of sleep apnea [central or obstructive) was not distinguished, we cannot comment on the prevalence and associations based on specific types of sleep apnea. <http://www.ncbi.nlm.nih.gov/htbin-post/Entrez/query?db=m&form=6&dopt=r&uid=11224009> Department of Rehabilitation Medicine, University of Washington, Seattle, Washington, USA.

While we have known for a long time that people with tetraplegia have a higher incidence of sleep apnea (breathing difficulties while sleeping), it is more prevalent that I thought, i.e. nearly 15% of the tetraplegic population. It is also interesting that while sleep apnea incidence correlates with injury level and obesity, it does not correlate with injury severity.

dr. young, i'm wondering if the conclusion that sleep apnea is most prevalent in obese people may be flawed...i was always a loud snorer and always slim...eventually i developed sleep apnea but it was long before the condition became well known and treated with cpap/bipap machines...by the time i saw a feature on television about sleep apnea and sought treatment i had gained a very signifigant amount of weight...my, then, wife saw the program and recognized the description of apneas and told me that was what i had been doing in my sleep for years...i sought treatment and using the bipap machine literally gave me a new life but the weight was already there and i haven't ever rid myself of most of it...my question is if there is any data that reverses the obesity/apnea conclusion...sleep apnea causing a change to a slow metabolism, as well as inactivity, resulting in uncharacteristic weight gain,,,that is what occured in my case,,,tedEbear

I have Sleep Apnea, I hate it. Some nights its like being murdered in your sleep, but repeatedly. It gives me frightening dreams of death.

Noel: To help you sleep better, you may want to see your practitioner for a referral to be evaluated for sleep apnea. Treatment is fairly simple (CPAP/BIPAP), although some people do not like it.

As far as I know, all insurance will pay for it (commercial or government).

noel, i can't stress how much of a difference you will notice in your life if you get treatment for your apnea...do you find yourself nodding off?...depression?...unable to concentrate?...on top of the sleeping difficulties?...i had as many as 100 apneas per hour lasting as long as 1 minute...i thought my life was over,,,then i tuffed it out using the bipap machine until i got used to it and, suddenly, i was back to being a human,,,i feel it literally gave me my life back...it's been 8 years now,,,medicare pays the bills...and i would strongly recommend you call a sleep center or specialist asap...and tuff out the first few nights...you will feel 100% better in about a week,,,tedEbear

I know I should do this but keep putting it off. As a quad living alone the treatment, headgear, appears not to be that simple. I doubt my ability to put the apparatus on and off. Nevertheless, I must be evaluated and treated, this sleep problem is wearing me down.

Jeff, thank you for the input your words are encouraging.

The nodding off is embarrassing. I try to take cat naps to prevent it. Depression is not a problem but I suspect my concentration is impaired.

If you don't mind, can you outline what you went through and how you treat apnea now?

Thanks again...

noel, when i started treatment it included 2 nights in the the sleep lab at the hospital but things have changed since then,,,you need to have a sleep study done,,,they will determine what machine you need and what settings are needed,,,they will orescribe a cpap or bipap machine for you,,,respironics makes a machine with a mask/headgear set up that can be managed...imho...by an independent quad...i prefer the old one they dont make anymore but such is life...for reference it is the blue head gear for a respironics cpap/bipap machine...tedEbear

A friend of mine who's an A/B had sleep apnea, and after he had a sleep study and was fitted with a mouthpiece, he says it has been a huge improvement in his life. Now, if I could convince my Dad to get a sleep study done...
