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.
