A   sleeping disorder that causes people to act   out their dreams would indicate brain disease in the future, study says. 
Researchers   led by Associate Professor John Peever of the University of Toronto found   that rapid eye movement sleep behavior disorder (or REMBD) is the most   accurate predictor of brain   diseases. These brain diseases include Parkinson’s disease, dementia, and   Alzheimer’s disease. 
According to   Peever, 80 to 90 percent of people experiencing REMBD may develop neurodegeneration, which   causes brain diseases. Neurodegeneration first affects the areas of the brain   that control sleep. Soon after, it affects areas concerned with brain   diseases. Most of the people diagnosed with REMBD are older males, especially   those who are over 50 years old. 
REMBD takes   place during the fifth stage of sleep – the rapid eye movement (REM) stage.   This causes people to act out their dreams, which sometimes results in   physically injuring themselves or   the ones beside them. On the other hand, those with healthy brains have their   muscles paralyzed temporarily during sleep. This instance prevents people   from acting out their dreams. 
It is easy   to know when one has REMBD. Those who are diagnosed with this disorder does   activities such as kicking, hitting, yelling, or jumping out of bed even when   asleep. 
The study,   which was published in the journal Trends in Neuroscience, suggests that   people who experience REMBD must be alert   and be open to get treatment for Alzheimer’s, dementia, Parkinson’s and other   brain diseases. 
Also, the   researchers advised the clinicians to recognize REMBD as a sign of brain   disease. Doing so will help the patients avoid developing more severe brain   diseases.
