Rem sleep behavior disorder夢遊

REM sleep behavior disorder (RBD) is a sleep disorder characterized by the loss of normal muscle atonia (muscle paralysis) during REM sleep, which is the stage of sleep typically associated with dreaming. People with RBD may act out their dreams, often with violent behaviors such as punching, kicking, or jumping out of bed. This can lead to injury to themselves or their bed partner. RBD is considered a parasomnia, which is a category of sleep disorders that involve abnormal behaviors, experiences, emotions, perceptions, and dreams that occur during sleep.

Dreaming typically occurs during REM sleep, and during this stage, the muscles are normally paralyzed. This muscle atonia is thought to prevent people from acting out their dreams and helps to protect them from injury. In RBD, this muscle paralysis is lost, allowing people to physically express their dreams.

RBD can occur in people of any age, but it is more common in middle-aged and older adults. It is more common in men than in women. RBD can be a symptom of a variety of neurological disorders, including Parkinson's disease, multiple system atrophy, and Lewy body dementia. It can also be a side effect of certain medications, such as antidepressants.

Treatment for RBD may include the use of medications to reduce the physical manifestations of the disorder, as well as behavioral therapies to help manage the condition. It is important for people with RBD to seek medical attention to ensure that any underlying neurological disorders are diagnosed and treated.
