Too little sleep in middle age linked to raised dementia risk: Study
Sleeping six hours or less per night in ลองเล่นสล็อตฟรี your 50s and 60s is associated with an
increased risk of dementia, according to a new study of nearly 8,000 British adults followed
for more than 25 years.
Scientists said that while the research, which was based on data from a long-running survey,
could not prove cause and effect, it did draw a link between sleep and dementia as people age.
The study, published on Tuesday (Apr 20) in the journal Nature Communications, showed
a higher risk of dementia in those sleeping six or fewer hours per night at the ages of 50 or 60,
compared to those who have a "normal" seven hours in bed.
There was also a 30 per cent increased dementia risk in those with consistently short sleeping
patterns from the age of 50 to 70, irrespective of cardiometabolic or mental health issues,
which are known risk factors for dementia.
The study authors from the French national health-research institute INSERM analysed data
from a long term study by University College London, which has followed the health of 7,959
British individuals since 1985.
Participants self-reported their sleep duration, while about 3,900 of them also wore watch
devices overnight to confirm their estimates.
Nearly ten million new cases of dementia, including Alzheimer's disease, are counted each year
worldwide, according to the World Health Organization, and disrupted sleep is a common
symptom.
But a growing body of research suggests sleep patterns before the onset of dementia could
also contribute to the development of the disease.
Time spent sleeping is linked to dementia risk in older adults - 65 years and older - but it is
unclear whether this association is also true for younger age groups, according to the authors.
They said future research may be able to determine whether improving sleep patterns can help
prevent dementia.
