Sleep disorder may signal dementia, Parkinson's disease up to 50 years early

7/28/2010

A new study shows that a sleep disorder may be a sign of dementia or Parkinson's

disease up to 50 years before the disorders are diagnosed. The research is

published in the July 28, 2010, online issue of Neurology, the medical journal

of the American Academy of Neurology.

Using Mayo Clinic records, researchers identified 27 people who experienced

rapid eye movement (REM) sleep behavior disorder for at least 15 years before

developing one of three conditions: Parkinson's disease, dementia with Lewy

causes symptoms similar to Parkinson's disease. People with REM sleep behavior

disorder often act out their dreams with violent movements, such as punching,

which can injure themselves or bed partners.
