Obstructive Sleep Apnea May Be Linked to Depression

FRIDAY, March 30 (HealthDay News) — There appears to be a link
between the common sleep disorder known as obstructive sleep apnea and
major depression, a new study suggests.

In people with obstructive sleep apnea, soft tissue in the back of the
throat blocks the upper airway during sleep. This results in pauses in
breathing and other sleep symptoms such as snorting, gasping and
snoring.

In the new study, U.S. Centers for Disease Control and Prevention
researchers surveyed about 9,700 American adults and found that 6 percent
of the men and 3 percent of the women said they had been diagnosed with
obstructive sleep apnea.

The CDC team found that symptoms of the sleep disorder were associated
with many depression symptoms, including feeling like a failure and
feeling hopeless. This association was not affected by factors such as
weight, age, sex or race, they noted.

There was no link noted between regular snoring and depression,
however, the researchers pointed out in the report, published in the April
issue of the journal Sleep.

“We expected persons with sleep-disordered breathing to report trouble
sleeping or sleeping too much, or feeling tired and having little energy,
but not the other symptoms,” such as hopelessness, lead study author Anne
Wheaton, a CDC epidemiologist, said in a news release from the American
Academy of Sleep Medicine.

Although the study uncovered an association between obstructive sleep
apnea and depression, it did not prove a cause-and-effect
relationship.
