People with REM Sleep Behavior Disorder often act out their dreams, like throwing up their arms to catch an imaginary ball or running away from imaginary assailants. This disorder is closely related to the progression of Parkinson's disease and other neurodegenerative diseases. In fact, the condition is associated with multiple system atrophy, which affects the body's ability to regulate involuntary functions.
Although RBD does not necessarily lead to the development of Parkinson's, it is a common early symptom of the disease. It can also precede other symptoms of the disease, including cognitive impairment, hallucinations, and daytime sleepiness. Fortunately, FDA-approved medications for Parkinson's disease can help with the condition.
RBD patients may be violent or aggressive. If they are not careful, they may hurt others or damage property. Some patients may act out their dreams unaware of their own actions. However, sleepwalkers almost never engage in RBD. It is important to talk to a sleep specialist to rule out any other sleep problems. Your doctor can also check whether you're at risk for developing Parkinson's disease. A movement disorder specialist may also recommend regular visits to monitor your symptoms.
