Results of a study published in the June 15, 2009 issue of the Journal of Clinical Sleep Medicine show that complaints of fatigue and tiredness in patients with obstructive sleep apnea (OSA) improved significantly with good adherence to continuous positive airway pressure (CPAP) therapy, suggesting that — like the symptom of excessive daytime sleepiness — these complaints are important symptoms of obstructive sleep apnea.
The results demonstrate good adherence to CPAP therapy for an average of five or more hours per night resolved baseline complaints of fatigue in 45 of 80 participants (56 percent), tiredness in 56 of 96 participants (58 percent) and sleepiness in 48 of 72 participants (67 percent); improvement of each symptom was significantly better among CPAP-adherent participants than among inadequately treated subjects. A baseline complaint of lack of energy also was resolved in 47 of 100 participants with good CPAP adherence, but this improvement failed to reach statistical significance when compared with inadequately treated participants.

A research abstract presented at Sleep 2009 demonstrates that sleep selectively preserves memories that are emotionally salient and relevant to future goals when sleep follows soon after learning. Effects persist for as long as four months after the memory is created.
Results show the sleeping brain seems to calculate what’s most important about an experience and then selects only what is adaptive for consolidation and long-term storage. Across delays of 24 hours, or even three-to-four months, sleeping soon after learning preserved the trade-off as compared to waiting an entire day before going to sleep.

A study published in the August 15, 2008 issue of the Journal of Clinical Sleep Medicine shows that surgical weight loss results in an improvement of obstructive sleep apnea (OSA), but most patients continue to have moderate to severe OSA one year after undergoing bariatric surgery. Results of this study suggest that it is the severity of the condition, rather than a patient’s pre-surgical weight, that determines if obstructive sleep apnea will be resolved.
Results show that bariatric surgery reduced body mass index (BMI) from an average of 51 to 32 in 24 adults with obstructive sleep apnea.

Got memory problems? If you suffer from obstructive sleep apnea, your brain could be to blame. UCLA researchers have discovered that people with sleep apnea show tissue loss in brain centers that help store memory.
Reported in the June 27 edition of the journal Neuroscience Letters, the findings emphasize the importance of early detection of the disorder, which afflicts an estimated 20 million Americans.

A study published in the April 1, 2008, issue of the journal Sleep confirms the persistent nature of insomnia and the increased risk of subsequent depression among individuals with insomnia. The study focused on 591 young adults, whose psychiatric, physical, and sleep symptoms were assessed with six interviews spanning 20 years.

Interesting Apnea Statistics
~~ Apnea in United States ~~
As of May 2, 2009 at 9:47 p.m. (-0500) (ET), the U.S. population
was 306,340,710. Sleep researchers estimate approximately seven percent
of the population suffers from obstructive sleep apnea. Using that
estimate, there are potentially 21,443,850 apneics in the U.S.
~~ Apnea around the world ~~
As of May 2, 2009 at 9:47 p.m. (-0500) (ET), the world population
was 6,777,286,604. Sleep researchers estimate approximately seven percent
of the population suffers from obstructive sleep apnea. Using that
estimate, there are potentially 474,410,062 apneics in the world.
