CPAP provides relief from depression

Researchers have found that continuous positive airway pressure (CPAP) treatment of obstructive sleep apnea (OSA) can improve depression symptoms in patients suffering from cardiovascular diseases.

Using data from the Sleep Apnea Cardiovascular Endpoints (SAVE) trial led by Flinders University, the new study has found a significant decrease in cases of depression after patients received CPAP treatment for their sleep apnea.

This is by far the largest trial of its type and one of very few studies reporting such an effect, says Professor Doug McEvoy from Flinders University.

From detailed analysis of the SAVE data, Flinders University experts and collaborators at the George Institute have found that CPAP for moderate-severe OSA in patients with cardiovascular disease has broader benefits in terms of preventing depression, independent of improved sleepiness.

Prior studies investigating the effect of CPAP on mood with various experimental designs and length of follow-up periods have yielded heterogenous results.

"Patients who have had a stroke or heart attack are prone to suffer from low mood and are 2 to 3 times more likely to develop clinical depression, which then further elevates their risk of future heart attacks and strokes," says SAVE principal investigator Professor McEvoy, a senior author in the paper just published by The Lancet in EClinicalMedicine.

With up to 50% of patients with CV disease likely to have OSA, the study is "welcome news that treatment of OSA substantially relieves cardiovascular patients' depressive symptoms and improves their wellbeing".

"After following them for an average of 3.7 years, we found that CPAP provided significant reductions in depression symptoms compared with those who were not treated for OSA. The improvement for depression was apparent within six months and was sustained."

As expected, those with lower mood scores to start with appeared to get the greatest benefit.

Wow! You really did need one.

I am on a business trip all next week but I will schedule with my doctor for an appointment. I have little doubt that I should be using one.

Thanks for the input.

It's life-changing. For the better. A little tough ta get used to initially. 'Specially if yer any kindof "Aliens" fan. Hehehe. d;^)
But a reasonable night's sleep quickly becomes addictive. Momma sez it's good "white noise" to sleep to.

CPAP is a life saver. Best thing I ever did.

97 is pretty high, glad you survived the crashes. My sleep Doc said he’s seen several AHI readings of 150+ and one guy hit 220. Anything over 30 is considered severe.
