Poor sleep linked to mental deterioration

Bloomberg News reports, “Older adults who have too much, too little or restless sleep have an increased risk for Alzheimer’s disease, according to studies” that were “presented…at the Alzheimer’s Association International Conference in Vancouver.”

HealthDay reports, “Evidence is building that poor sleep patterns may do more than make you cranky: The amount and quality of shuteye you get could be linked to mental deterioration and Alzheimer’s disease, four new studies suggest.”

Of these studies, “the largest…which examined data on more than 15,000 women in the US Nurses’ Health Study, suggested that those who slept five hours a day or less, or nine hours a day or more, had lower average mental functioning than participants who slept seven hours per day.”

The research was “scheduled for presentation at the Alzheimer’s Association annual meeting in Vancouver.” Since these findings are to be presented at a medical conference. They should be considered preliminary as they have not yet undergone the “peer review” process, in which outside experts scrutinize the data prior to publication in a medical journal.

WebMD reports, “The link between sleep duration and memory held true both in mid-life and later life…says” one of the researchers.
