Sleep 9 hours or more associated with an increased risk of dementia

For this study, a large number of adults enrolled in the FHS enrolled as long as they slept normally per night. Researchers followed the participants for 10 clinical years to see who developed Alzheimer's disease and other dementia.

 "The researchers then investigated BUSM data collected on sleep duration and calculated the risk of developing dementia.



The team found out that people who sleep for 9 hours regularly or more were twice as likely to develop Alzheimer's disease in 10 years, compared to those who regularly slept less than 9 hours.Furthermore, as the main author of the study stated, education appears to play a role to prevent the risk of dementia.




    
"Participants without high school slumber sleep more than 9 hours a night had six times the risk of less than 10 years compared to participants developing dementia that slept by menos.Estos suggest that its highly educated can protect against dementia in Long-term presence of sleep. "

The study found that people who slept longer seemed to have smaller brains. Observation studies can not establish causality, but the researchers suspect that excessive sleep is probably a symptom and not as a cause of neural changes that come with dementia. As a result they speculate, reduced sleep is unlikely to reduce the risk of dementia.

Alzheimer's disease affects millions of Americans, and the number should increase. New research suggests that there may be a link between long sleep and the risk of dementia.

 More than 46 million people with dementia worldwide, and the number is expected to triple by 2050.In the US, it is currently estimated that more than 5 million people suffer from Alzheimer's disease. The disease risk increases with age, and only 1 to 3 elderly people die with Alzheimer's disease or any other form of dementia.The financial burden of the disease is greater. It is believed that American families spend more than $ 5,000 a year in the care of a person with Alzheimer's, and the national economic burden is estimated at $ 236 billion.A new large study suggests that people with longer sleep patterns may have an increased risk of developing dementia.The research was conducted at Boston University (BUSM) at the Faculty of Medicine of Dr. Sudha Seshadri neurology professor led and the results were published in the journal Neurology.The researchers examined data from the Framingham Heart Study (FHS). FHS is a large cohort study that began in 1948 to accommodate 5209 men and women between 30 and 62 years living in the city of Framingham, MA. The original purpose of the study was to identify risk factors for cardiovascular disease.
