Data from the Framingham Heart Study has shown that people who consistently sleep more than 9 hours each night had double the risk of developing dementia in 10 years as compared to participants who slept for 9 hours or less. The findings, which appear in the journal Neurology, also found those who slept longer had smaller brain volumes.
A large group of adults enrolled in the Framingham Heart Study (FHS), were asked to indicate how long they typically slept each night. Participants were then observed for 10 years to determine who developed dementia, including dementia due to Alzheimer’s disease. Researchers from Boston University School of Medicine (BUSM) then analyzed the sleep duration data and examined the risk of developing dementia.
“Participants without a high school degree who sleep for more than 9 hours each night had six times the risk of developing dementia in 10 years as compared to participants who slept for less. These results suggest that being highly educated may protect against dementia in the presence of long sleep duration,” says co-corresponding author Sudha Seshadri, MD, professor of neurology at BUSM and FHS senior investigator, in a release.
According to the researchers the results suggest that excessive sleep may be a symptom rather than a cause of the brain changes that occur with dementia. Therefore, interventions to restrict sleep duration are unlikely to reduce the risk of dementia.
“Self-reported sleep duration may be a useful clinical tool to help predict persons at risk of progressing to clinical dementia within 10 years. Persons reporting long sleep time may warrant assessment and monitoring for problems with thinking and memory,” adds co-corresponding author Matthew Pase, PhD, fellow in the department of neurology at BUSM and investigator at the FHS.
The researchers believe screening for sleeping problems may aid in the early detection of cognitive impairment and dementia. The early diagnosis of dementia has many important benefits, such as providing a patient the opportunity to more activity direct their future plans and healthcare decisions.
These three extracts – from the introduction and from the attached paper.
“Sleeping longer than 9 hours may be a sign of early dementia”
“According to the researchers the results suggest that excessive sleep “may” be a symptom rather than a cause of the brain changes that occur with dementia.”
“Therefore, interventions to restrict sleep duration are unlikely to reduce the risk of dementia.”
Once again, tell the sorry tale of the revolving door, Blackboard Mathematics and back to front Scientific research Thinking. Confirmed by the use of one small word. “MAY.”
Thus, do nothing, but muddy the water of a satisfactory understanding of these two Symptoms “Sleep-Dementia,” if one has no comprehension that sleep-time, excessive sleep or no sleep is the seedbed for the creation and sustaining of all illness.
Therefore, both are only a reaction to a memory and nothing whatsoever to do with each other.
