We have previously written at HuffPost UK about how some people who have sects see at times that their sleep period long years before the diagnosis.
Now, paper It was published in Al -Zheimer and Death Magazine Another connection was suggested between the rapid eye movement (REM) and early Alzheimer’s disease.
What did the study found?
REM sleep – the last four stages of sleep we are going through several times per night – usually when we dream.
Each sleep cycle usually takes 90 minutes or more to complete it.
The study, which included 128 participants with mixed dementia and dementia -free position, found that people who have no condition took about 98 minutes to reach REM.
Those who suffer from dementia, on the other hand, seemed to take much longer (193 minutes) to reach REM, or “dream”, from the stage of those who have no condition.
People who took longer to reach the theater, on average, were more than 16 % amyloid and 29 % Tao in their brains. Each of these proteins has been associated with the development of dementia.
Dr. Yi Ling, the co -author of the study Neuroscience news One of the reasons that may be important is that we integrate our memories during the sleeping of the remnant.
He said: “The delay in the sleeping of the remnant disrupts the ability of the brain to unify memories by interfering in the process that contributes to learning and memory.”
“If it is not enough or delay, it may increase the cortisol stress hormone, [which] It can weaken the hippocampus in the brain, which is a decisive structure to unify the memory. ”
What causes the de delay?
The paper says Some medications, alcohol, stop breathing and other disturbances in our normal sleep cycle can affect the speed of REM.
The study does not prove that the delay of the Rem definitely means that you have dementia. It only shows an association.
“Future research should study the effects of some medications that affect sleep patterns, because these may adjust the development of the disease,” Dr. Ling told nervous science news.
Currently, though, our best bet is to stick to lifestyle options to reduce risk, such as eating well, exercise, and social survival wherever possible.
