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