A US study shows that a disturbance in sleep and wakefulness could be early signs of Alzheimer's disease. The research at Washington University School of Medicine in St. Louis said the disruption of the circadian rhythm occurs much earlier in people, the memories are intact, but whose brain imaging reveals early evidence preclinical Alzheimer's disease. The results, published on Monday in the journal Archives of Neurology, doctors can help people at risk for Alzheimer's disease to identify earlier is now possible because of Alzheimer damage root in the brain may take 15 to 20 years before clinical symptoms, Xinhua said. Here are 10 conditions that afflict the elderly.
"It's not that people were deprived in the study of sleep," said Erik S. Musiek, assistant professor of neurology.
"But his dream tends to fragment. is sleep eight hours a night greatly to eight hours of sleep per hour steps during daytime naps. "The researchers also conducted a separate study in mice, to 30 January in the Journal of Experimental Medicine shows that circadian disorders such as the development of amyloid plaques in the brain accelerate that are associated with Alzheimer's disease. Previous studies at the University of Washington, carried out on humans and animals have found that amyloid levels fluctuate throughout the day and night expected. Amyloid levels and lowers during sleep, and several studies have shown that levels increase when sleep is interrupted or if people do not get enough sleep, carried out according to a study by lead author Yo-El Ju. "In this new study found out that people with preclinical Alzheimer's disease have a greater fragmentation in their circadian activity patterns, more downtime or sleep at times of the day and night exercise," Ju said assistant professor of neurology. Here are 6 tips to prevent the onset of Alzheimer's disease.
The study found that subjects who have a short time of activity and rest during the day and at night rather were evidence of the accumulation of amyloid in the brain. The two researchers said it is too early yet to the question of the chicken and the egg, if changes in circadian rhythms change people for Alzheimer's disease or related changes in Alzheimer's disease threatened to answer the brain circadian rhythms. "At least these changes in circadian rhythms can be used as a biological marker for preclinical disease," Ju said. "We want to bring more information about these issues in the future to see if your sleep and circadian rhythm disorders lead to an increased risk of changes in the brain or sleep because of Alzheimer Alzheimer's disease and wakefulness and circadian problems.
