Can a sleep study diagnose depression??

I just recently had a sleep study done to check for sleep apnea .... my doctor just called and left me a message that " I had very mild sleep apnea which did not require the use of cpap but he had indications of severe depression"
Question; Does a sleep study alone provide information to make such a diagnosis??

HELL NO! your doctor is a quack. i ran sleep labs across the country for like 8 years and the most commonly misdiagnosed thing i see is drs. thinking their patients are depressed when they really have apnea. THERE IS NO WAY A POLYSOMNOGRAPHY CAN TEST FOR DEPRESSION! i'd get a new dr...

I agree that it cannot SHOW depression. BUT, if you are not getting the sleep you need, I can see where that would make you depressed. I would do another study. If you have sleep apnea that will interfere with quality of sleep.
If you are overweight, losing weight will help with sleep apnea.
Whatever you do, consult another doctor.
Good luck!

I have had sleep studies. I was diagnosed with sleep apnea. I also have severe depression. Sleep apnea and other sleep problems can make you feel mildly depressed, but depression messes with your sleep. If you have bad sleep problems and no physical cause, then I don't think suggesting you be checked for depression is out of line. It's also possible you had other things going on, such as night terrors or talking in your sleep, that made the dr. think of a mental issue. Call him back and ask!
