New research published recently in the Annals of the American Thoracic Society shows a newly discovered link between sleep-breathing disorders such as sleep apnea and problems with memory and paying attention.  

The study looked at 1,700 adults using technology in their home environment to measures things like oxygen levels and other functions during sleep. Researchers determined that those with less than 90 percent oxygen saturation levels, which is a clear marker for sleep apnea, scored much lower on memory and attention tests. Researchers believe the lack of oxygen can damage blood vessels in the brain and cause inflammation that can result in nerve cell loss and lead to cognitive problems.
