University of Penn researchers find way to reverse cognitive impairment caused by sleep deprivation

A recently published study that is the first to assess the effectiveness of treating sleep disorders in adults with a traumatic brain injury (TBI) shows treatment may result in the objective resolution of the sleep disorder without improvements in daytime sleepiness or neuropsychological function.
Results show that in brain-injured subjects with obstructive sleep apnea, three months of treatment with CPAP therapy dramatically reduced the severity of OSA from 31.4 to 3.8 apneas and hypopneas per hour of sleep; however, there was no demonstrable improvement in measures of daytime sleepiness.

Who should have surgery for sleep apnea?
Answering the question: Who should have surgery for sleep apnea?
Even as more and more people in the United States are diagnosed with obstructive sleep apnea (OSA), there remains a disconnect as to who can benefit from corrective surgery. Leading experts in the field of sleep medicine will attempt to answer the question of who could benefit from surgery, during a moderated discussion.

Exploring the many functions of sleep
Is sleep essential? Ask that question to a sleep-deprived new parent or a student who has just pulled an “all-nighter,” and the answer will be a grouchy, “Of course!”
But to a sleep scientist, the question of what constitutes sleep is so complex that scientists are still trying to define the essential function of something we do every night.

A Swedish study reveals that children who grow up in a large family or who are exposed to animals often have respiratory or ear infections in early life are more likely to develop into snorers in later life.
Snoring is not just a potential annoyance. In some cases, it can be a sign of a potentially fatal respiratory condition known as obstructive sleep apnea which causes a narrowing or collapse of the throat during sleep, and as a result, can increase the risk of heart disease and stroke, lead to memory loss, depression, diabetes, among other health issues.

A press release issued by the American Association of Diabetes Educators says that 94 percent of doctors in a survey the organization conducted were aware of the links between the development of type 2 diabetes in people who have obstructive sleep apnea.
Despite knowing about the link, only about 47 percent of the physicians involved in the survey actually conduct routine screenings.

An independent link between sleep apnea and mortality has been discovered by a group of Australian researchers, suggesting the prevention and treatment of this condition should be a higher priority for government bodies working to improve community health.
The study conducted by the Woolcock Institute of Medical Research in Sydney found moderate to severe obstructive sleep apnea (OSA) was associated with 33 percent mortality over 14 years compared to 7.7 percent mortality in people with no sleep apnea.

Research questions use of sleep meds for apneics
Prescription sleep aids may do little to improve the use of continuous positive airway pressure devices (CPAP) among patients with obstructive sleep apnea (OSA).
A new study published in the November issue of CHEST, the peer-reviewed journal of the American College of Chest Physicians (ACCP), finds that patients with OSA who were given prescription sleep aids were no more likely to use their CPAP machines than patients with obstructive sleep apnea taking a placebo.
