Over the last few years, the medical community has placed more focus on the physical problems linked to sleep apnea. Various studies have shown definite correlations between people suffering from the sleeping disorder and various medical conditions such as diabetes, increased blood pressure, irregular heartbeats, stroke and depression. A medical study from the Journal of the American Medical Association has shown a new problem linked to sleep apnea – dementia.

Understanding the Link

When people with sleep apnea choose to go without treatment (including CPAP machine therapy), their troubled breathing can lead to hypoxemia, or a decrease in the amount of oxygen found in the human blood supply.

According to Dr. W. McDowell Anderson, the director of the sleep medicine training course at University of South Florida, there has been a suspicion for years that cognitive problems could be linked to hypoxemia. This specific study was developed in such a way that the researchers were able to draw a conclusion that hypoxemia, caused by sleep apnea, can have a negative ...
... impact on cognitive function.

Premise of the Study

Dr. Kristine Yaffe from the University of California located in San Francisco, was in charge of the study. Scientists studied 298 women in their later years that showed no signs of any cognitive problems. Just over 100 of these women suffered from sleep apnea. These women were found to have a minimum of 15 episodes during their nightly sleep in which their breathing stopped long enough that the oxygen amounts in the blood dropped.

During the 5 year study, almost 45% of the women with sleep apnea showed signs of slight impairment of cognitive ability, also known as dementia. That is a contrast to the 31% of the women without any sleep problem that developed dementia. Based on the parameters of the study, the researchers could link the onset of cognitive problems to the cases of hypoxemia.

Treatment is Available

After the study was published, an editorial from that issue advocated for early diagnosis and aggressive pursuit of sleep apnea treatment via a CPAP machine. Numerous studies have shown that a CPAP machine is highly effective in treating sleep apnea when used properly and consistently. The editorial argued that since decreased oxygen levels can be effectively treated, doctors should pursue diagnosis earlier in a patient’s life to help prevent any dementia through sleep apnea.

With sleep apnea, a person’s soft palette and tongue compresses the airway when at rest during the night.Use of a CPAP machine provides much needed oxygen during sleep.

The doctors that were involved with the study, as well as sleep therapy specialists, are happy that this information is becoming widely available to the medical community. This type of concrete evidence will hopefully lead to more doctors recommending sleep screenings for patients in hopes of catching sleep apnea at an earlier age.
