Older Adults’ Forgetfulness Tied To Faulty Brain Rhythms In Sleep
December 18, 20174:47 AM ET Heard on Morning Edition – NPR.org Older brains may forget more because they lose their rhythm at night. During deep sleep, older people have less coordination between two brain waves that are important to saving new memories, a team reports in the journal Neuron. “It’s like a drummer that’s perhaps just one beat off the rhythm,” says Matt Walker, one of the paper’s authors and a professor of neuroscience and psychology at the University of California, Berkeley. “The aging brain just doesn’t seem to be able to synchronize its brain waves effectively.” The finding appears to answer a long-standing question about …
Obstructive sleep apnea linked to higher Alzheimer’s risk
By Maria Cohut | Published Friday 10 November 2017 | MedicalNewsToday.com Fact checked by Jasmin Collier A new study has demonstrated that older adults who experience obstructive sleep apnea may be at increased risk of Alzheimer’s disease. This is because they exhibit higher levels of amyloid beta, the chief component of the amyloid plaques that characterize the disease. Obstructive sleep apnea is characterized by the occasional inability to breathe while asleep, due to a collapse of the airway. This may cause the sleeper to wake up repeatedly during the night whenever breathing becomes difficult, resulting in disturbed sleep patterns. Recent data suggest that in the …

Sleep Apnea Tied to Cognitive Decline
Monday, 28 Aug 2017 03:17 PM | NewsMax.com People who experience certain breathing problems at night may be more likely to develop cognitive impairment than individuals without any difficulties breathing while they sleep, a research review suggests. Data obtained from 14 previously published studies with a total of more than 4.2 million men and women showed that people with sleep-disordered breathing had 26 percent higher odds of developing cognitive impairment, researchers report in JAMA Neurology. “Identification of this sleep disorder in elderly persons might help predict future risk of cognitive impairment and thus is important for the early detection of …
The Scary Way Snoring Can Tank Your Brain
Similar risks apply if you wake up feeling zonked, too BY CHRISTA SGOBBA | July 24, 2017 | MensHealth.com Snoring at night doesn’t just drive your partner crazy—it might signal a serious problem for your brain. People with sleep-breathing disorders tend to have poorer memory and trouble paying attention, new research in the Annals of the American Thoracic Society suggests. In the study, researchers tested 1,700 older adults with at-home polysomnopgraphy, a tool that measures oxygen level and other sleep factors during shuteye, and surveyed them on their sleep habits. Then, the participants took some tests to measure their cognitive …
Sacrificing sleep? Here’s what it will do to your health
