According to data collected in the past 30 years, there are about 8,000 people, and scientists have established a link between sleep time between 50 and 60 years old and Alzheimer’s disease
Last time Frontier XXI ProjectOn the topic of dementia, Luísa Lopes, a neuroscientist and researcher at the Institute of Molecular Medicine, warned: “In Portugal, we seldom pay attention to sleep” and one of the ways to maintain brain health is “proper sleep”.
For some time, scientists have been skeptical about the relationship between the time we spend in sleep and the risk of developing pathologies that affect cognitive ability and memory. A study The article just published in the journal Nature Communications helps to clarify the nature of this relationship. The author of the article wrote: “Here, people in 50 and 60 have a higher risk of dementia associated with sleep duration of six hours or less compared to the normal seven hours.”
For this work, we analyzed the data of 7,959 Britons collected over the past 30 years. There is no doubt that continuous lack of sleep will increase the risk of dementia by 30% regardless of other factors. Such as social demographics, behavior, cardiometabolic and mental health. “These findings indicate that lack of sleep in middle-aged people is associated with an increased risk of dementia in the future.“, resume.
Until now, studies that attempted to establish a relationship between the two symptoms were conducted only in the ten years before the volunteers developed the first symptom, and the results are inconclusive.
Of the nearly 8,000 consecutive volunteers, 521 had symptoms of dementia. however, The author of this work emphasizes that no causality has been found. The common symptoms of these diseases are precisely the changes in sleep patterns. although, It is not clear whether lack of sleep is the root cause of the problem or the early manifestations of the disease itself.
In the work currently published and coordinated by the University of Paris, the database of University College London is used, and the article is available online.
If the relationship between sleep is not known, then scientists will undoubtedly take some actions. In order to maintain the health of the brain, you must: do physical exercise, maintain healthy eating habits, monitor cardiovascular health, not smoke or drink alcohol, and avoid multitasking.
