The relationship between self-reported snoring, headache and cognitive
complaints (memory and concentration problems) was evaluated in an ep
idemiologic survey including 3,323 males, with a mean age of 63 (53-75
) years. Fourteen potential confounders were examined. A strong associ
ation between snoring and headache was found, persisting after correct
ion for potential confounders. An association was found between snorin
g and cognitive complaints only in those who reported good sleep quali
ty without insomnia.
