Called the dangerous consequences of a lack of dreams

Australian researchers found that the reduction of REM sleep, during which man sees dreams, is associated with high risk of dementia. A study published in the journal Neurology, briefly about it, reports the American Academy of neurology.

The experiment involved 321 people from Massachusetts (USA) with an average age of 67. For people watched (including tracking the rhythms of the brain) for about 12 years. During this time, 32 people have been diagnosed with a form of dementia, a 24 — Alzheimer’s disease.

That reduction in REM sleep and not in other periods, as shown by the authors, was associated with dementia. In fact, the decline of one percent duration of REM sleep is positively correlated with an increase of nine percent risk of developing dementia.

“Our results indicate that REM sleep as a predictor of dementia, said co-author Matthew Pace. In the future, we have to understand the reasons for the short duration of REM sleep is associated with a greater risk of dementia”.

There are five phases of sleep. The period of REM sleep is the last of them, and is characterized by increased brain activity. At this time people are generally watching dreams, and his eyeballs to make quick movements.
