A new study has suggested that sleeping for more than nine hours each night may predict the risk of developing dementia.
The study, which featured recently in the journal Neurology, took into consideration how long participants typically slept each night, followed by observation for 10 years to see who developed Alzheimer’s disease and other forms of dementia.
Out of 2457 people, 234 patients developed all-cause dementia, to which researchers linked prolonged sleep duration with a higher risk of incident dementia.
However, it remains unclear if sleep duration is a risk factor or a marker for dementia.
Sudha Seshadri, MD, neurology professor at Boston University School of Medicine led the study. He said: “Participants without a high-school degree who sleep for more than nine hours each night had six times the risk of developing dementia in 10 years 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.”
