Risk Factors And Complications Linked To REM Sleep Behavior Disorder

Neurodegenerative Diseases

Lewy body dementia has also been linked to REM sleep behavior disorder. This type of dementia is the second most common progressive dementia, with the first most common being Alzheimer's disease. It occurs when proteins called Lewy bodies build up in the brain, leading to degeneration over time. Other neurodegenerative diseases have been associated with REM sleep behavior disorder as well. Some of them are Shy-Drager syndrome, multisystem atrophy, and Parkinson's disease. Parkinson's disease progressively affects an individual's movement, beginning with tremors that worsen over time. Shy-Drager syndrome is a rare disorder that causes slow movement, tremors, postural instability, and muscle rigidity because of dysfunction in the basal ganglia.
