\n Maybe you know you snore like a bear, but you don\u2019t feel much urgency to look into it. Or maybe you have been told to wear a continuous positive airway pressure, or CPAP, machine for sleep apnea, but it is just so cumbersome.\n <\/p>\n
\n A new study shows that it is important to take obstructive sleep apnea seriously now \u2013\u2013 it could impact your risk of dementia and Alzheimer\u2019s disease later.\n <\/p>\n
\n Moderate to severe obstructive sleep apnea is associated with a greater risk for new microbleeds in the brain, according to the study.\n <\/p>\n
\n \u201cCerebral microbleeds are a common finding in the aging brain,\u201d said Dr. Jonathan Graff-Radford, professor of neurology at Mayo Clinic College of Medicine in Rochester, Minnesota. He was not involved in the research.\n <\/p>\n
\n Microbleeds increase with age, and people who have them have a slightly higher risk of future strokes and faster cognitive decline, Graff-Radford said. \u201cAnything that increases microbleeds is relevant to brain aging,\u201d he added.\n <\/p>\n
\n Obstructive sleep apnea is a condition in which a blockage of airways by weak, heavy or relaxed soft tissues disrupts breathing during sleep. The condition is different from central sleep apnea, in which the brain occasionally skips telling the body to breathe.\n <\/p>\n
\n There are a few ways to treat<\/a> obstructive sleep apnea, including relying on oral devices that keep the throat open during sleep, regularly using a CPAP or similar machine, and having surgeries.\n <\/p>\n \n The study has a strong methodology and should stress the importance of screening for sleep apnea to clinicians and treatment to patients, said Dr. Rudy Tanzi, professor of neurology at Harvard Medical School and director of the Genetics and Aging Research Unit at Massachusetts General Hospital in Boston. He was not involved in the research.\n <\/p>\n \n \u201cDon\u2019t ignore it. Do something about it,\u201d he said. \u201cIt\u2019s not just the immediate risk for down the road for bleeds, but also later down the road for Alzheimer\u2019s disease as well.\u201d\n <\/p>\n \n Not addressing obstructive sleep apnea is a double whammy, Tanzi said. Not getting enough good-quality sleep \u2013\u2013 which can be hard to do when your breathing is impaired during the night \u2013\u2013 has been associated with brain aging, but the microbleeds that could result may increase the risk for dementia down the line.\n <\/p>\n \n The study, which was published in the journal JAMA Network Open<\/a> Tuesday, is observational, which means that it can only establish that obstructive sleep apnea and microbleeds are associated, not that one definitively causes the other. Further studies will need to examine if treating sleep apnea can prevent microbleeds.\n <\/p>\n \n When is it time to ask your doctor about obstructive sleep apnea?\n <\/p>\n \n Loud, frequent snoring is a good indicator, Tanzi said. If your partner notices pauses in your breathing while you sleep or gasping and choking, that\u2019s another sign you should look into sleep apnea.\n <\/p>\n \n Problems during the day can be a good indicator, too. Sleepiness, trouble concentrating, irritability and increased hunger are signs you may not be getting quality sleep and that it may be time to get assessed for sleep apnea.\n <\/p>\n \n Night sweats might also be a sign of sleep apnea, as research has shown that about 30% of people<\/a> with obstructive sleep apnea have reported night sweats.\n <\/p>\n \n Waking up at least two times<\/a> in the night, teeth grinding<\/a>, and morning headaches<\/a> might also indicate a problem.\n <\/p>\n \n The latest study \u201curges (people) to take it more seriously, because the damage that can come from obstructive sleep apnea can definitely be more severe than you think,\u201d Tanzi said.\n <\/p>\n
