Sleep-disordered breathing (SDB) has been associated with poor cognition in previous research, but it had been unclear whether SDB preceded this impairment in cognition. New research, co-authored by Susan Redline, a researcher in the Division of Sleep Medicine at Harvard-affiliated Brigham and Women’s Hospital (BWH), finds that SDB is associated with and precedes a higher risk of cognitive impairment in older women. These findings will be published in the Aug. 10 issue of the Journal of the American Medical Association.“Even after adjusting for age, body mass index, education, diabetes, and baseline cognitive scores, we found that indices of hypoxia, but not sleep fragmentation or duration, were associated with increased risk for mild cognitive impairment and dementia, suggesting that hypoxia is a likely mechanism through which SDB increases risk for cognitive impairment,” said Redline, who is the Peter C. Farrell Professor of Sleep Medicine at Harvard Medical School (HMS).Researchers studied nearly 300 women with a mean age of 82, free of dementia at initial examination. Between 2002 and 2004, 105 of these women were diagnosed with SDB defined as having 15 or more apneas and intermittent hypoxemia per hour of sleep. Five years later, they followed up with the women to determine their cognitive status, which was classified as normal, dementia, or mild cognitive impairment (MCI). Researchers found that compared to the women without SDB, those with SDB were nearly two-fold more likely to develop cognitive impairment.“More research is needed to explore the association between hypoxia and risk of MCI/dementia, which could provide clues into the mechanisms through which SDB might promote cognitive impairment,” said Redline. “Given the high prevalence of both SDB and cognitive impairment among older adults, the possibility of an association between the two conditions, even a modest one, has the potential for a large public health impact. This prospective study supports the need for intervention studies to assess whether treatment of SDB may prevent the development of cognitive impairment.”The lead author is Kristine Yaffe of the University of California, San Francisco. Co-author Katie Stone of California Pacific Medical Center directed the Coordinating Center for the study, while co-author Redline directed the sleep study analysis. This research was conducted using the Study of Osteoporotic Fractures (SOF) cohort, which is supported by the National Institutes of Health.

The company has agreed not to build a mall on the property.Mall or Nothing: The Battle Over Syosset Shopping Center“Unfortunately for the taxpayers of Oyster Bay, the Town and Simon’s misinformation campaign allowed them to slip their rotten deal past the public in a low turnout election,” Long Island Jobs Now, a Taubman affiliated group opposed to the referendum, said in a statement.“The referendum was never about a mall, which can still be built on Taubman’s property,” the statement continued. “We will continue to push this case in the courts and are committed to making sure the Town acts in the best interests of its taxpayers rather than Simon Property Group – whose only interest is maintaining its mall monopoly.”Venditto had choice words for Taubman, as well.“The residents of the Town of Oyster Bay have spoken and by a 2:1 margin, rejected Taubman’s mall, Taubman’s greed, and Taubman’s shameful and unethical behavior throughout the entire referendum campaign,” the supervisor said.
