Friday, April 17, 2015

YARMOUTH, Maine – Sleep disordered breathing is associated with early mental decline and Alzheimer’s disease, but treatment with CPAP therapy may delay the onset of problems, according to a new study. Researchers at New York University Langone Medical Center found people with sleep-disordered breathing became cognitively impaired an average of about 10 years sooner than those without the disorder. They also found, compared to those whose sleep disorder was untreated, those using CPAP therapy delayed the appearance of cognitive impairment by an average of 10 years. The study, which was published online in Neurology, analyzed information on the incidence of sleep-disordered breathing and the incidence of mild cognitive impairment and Alzheimer’s disease in 2,470 people with the average age of 73.
