New Alzheimer’s Disease risk study suggests that people who tend to sleep for more than 9 hours every day are more predisposed to developing the condition in the next decade than people who sleep for 8 hours or less. Based on the numbers, people who refuse to get out of bed after 9 hours of sleep are twice more likely to exhibit dementia-related symptoms.
A team of researchers from the Boston School of Medicine has discovered that people who oversleep are twice more likely to exhibit the telltale signs of dementia in the next decade than people who settle for eight or fewer hours of sleep.
Although the exact set of circumstances that trigger dementia have yet to be uncovered, a new study might be a great first step in the direction of identifying and delaying the condition’s first symptoms. Working on the data collected from the Framingham Heart Study, the scientists involved in the project have discovered that even the hours spent in bed can tell us if an individual can develop dementia.
Approximately 2,400 participants were involved in the Framingham Heart Study and the subsequent dementia risk study. As part of the project, the respondents were asked to write down the number of hours spent in bed each night.
The researchers studied the participants’ evolution over a period of 10 years. The study’s results are more than encouraging for the future of dementia prevention strategies. All participants who declared that they usually sleep 9 to hours per night were twice more likely to experience cognitive impairment in the next ten years than participants who sleep 8 hours or less.
In addition, the researchers have determined that education is also in an important factor which shapes the patient’s dementia predisposition. As a result, all participants who didn’t have a high school diploma and spent at least 9 hours in bed were six times more likely to develop dementia in the next ten years than those with a high school degree. The researchers have also noted that this category of participants had a decreased brain volume.
On the other hand, participants with a higher education had fewer chances of developing dementia in the next decade, but they tend to sleep less. The facts uncovered by the study can help scientists developed new preventive strategies and ways to identify people who are predisposed to this condition.
