The difficulty in diagnosing the development of Alzheimer's disease is that the symptoms of this disease is the loss of clarity of the mind or memory loss - become visible only in the later stages of development. Scientists who conducted experiments on mice, found a predictor of Alzheimer's disease can be sleep problems.
One of the reasons of occurrence of this disease is called the presence of clots protein (platelets) in the brain. Washington researchers published in the journal Science Translational Magazine sensational statement: at the moment of appearance in the brain of mice first of platelets, in rodents had a problem with sleep. Such a statement suggests that now the doctors will have a new effective diagnostic tool this is the most common form of dementia. The key to successful treatment of Alzheimer's disease lies in the determination of the signs of the disease at its earliest stages, however, the signs of the disease become apparent only when brain cells are so damaged that the treatment is ineffective or impossible. This is why the ability to diagnose the presence of Alzheimer's disease early in development for many years before the onset of visible symptoms is to find researchers.
Scientists from the University of Washington noticed clumps of beta-amyloid from the brain. Indicators of this protein change, as in humans and in mice, during the day. However, in Alzheimer's disease clumps of beta-amyloid are constant. In normal mice slept for 40 minutes every hour, but when the protein levels increased, sleep mice decreased to half an hour.
Unfortunately, the results of experiments on mice, it is not always possible to apply to people, to the same reasons for poor sleep are many.
