Internal Medicine

REM Sleep Behavior Disorder (RBD) is significantly more common in men than in women. Research shows that men, particularly those over the age of 50, account for the majority of diagnosed RBD cases. While women can also develop the disorder, studies consistently indicate a strong male predominance, with some estimates suggesting men are affected up to 4 times more often.

If you or a loved one are experiencing symptoms like acting out dreams, sudden movements during sleep, or unexplained nighttime disturbances, it's important not to ignore them. RBD can sometimes signal underlying neurological conditions, and early awareness matters. Take a free, instant, online symptom check to better understand what may be going on and confidently navigate your next steps.
