What is REM sleep behavior disorder?
REM or rapid eye movement is a part of the natural sleep cycle and is often the time in which dreams occur. In REM sleep behavior disorder, you act out your dreams with leg or arm movement and vocal sounds. It typically comes on gradually and gets worse with time, and it can sometimes be attributed to other diagnoses, including Parkinson’s disease or dementia.
What causes REM sleep disorder?
Typically during a normal REM cycle, nerves prevent movement. However, in those with REM sleep behavior disorder, these nerve pathways don’t work the way they should, resulting in the acting out of dreams.
Certain conditions can also increase your chance of developing REM sleep behavior disorder. Disorders like Parkinson’s, stroke or narcolepsy can all put you at a higher risk for developing the condition, as can taking certain antidepressants or being male over the age of 50.
What are the symptoms of REM sleep disorder?
While the REM portion of the sleep cycle doesn’t usually involve movement, those with REM sleep behavior disorder can often kick, punch, laugh or talk during REM. They are also able to recall the dream they were acting out if they are awoken during the episode. These episodes of movement can occur multiple times a night.
How is REM sleep disorder diagnosed?
Your healthcare provider can diagnose REM sleep disorder through physical and neurological exams. He or she may also order an overnight sleep study or polysomnogram to evaluate your body movements, heart rate, oxygen levels and vocalizations as you sleep. Since REM sleep disorder can mimic other sleep disorders, it’s important to talk with your provider so you can receive an accurate diagnosis.
How is it treated?
Your healthcare provider will help determine the best course of treatment for REM sleep behavior disorder. Medications or supplements, such as melatonin and clonazepam, can help decrease the symptoms of REM sleep behavior disorder and provide you the opportunity for a more restful night’s sleep. Prior to taking any medications, it’s important to discuss with your provider any concerns you might have and any side effects to expect.
Additional management options for REM sleep disorder may include creating a safe sleeping environment so that you don’t injure yourself or others during an episode. This might include moving furniture away from the bed, protecting windows, or padding the floor of the bedroom.
