Rapid eye movement sleep behavior disorder is associated with an increased risk of developing Parkinson’s disease — and researchers have demonstrated that inflammation may play a key role, reports Medical News Today.
Rapid eye movement (REM) sleep behavior disorder (RBD) is linked with vivid and often frightening dreams combined with nocturnal motor activity. In other words, people with the condition act out their dreams.
Dreaming occurs during REM sleep. In this sleep phase, our bodies are effectively paralyzed and our muscles remain relaxed; this prevents us from thrashing around.
Individuals with RBD, however, can experience violent arm and leg movements and even shout during their dreams. This is referred to as dream-enacting behavior.
