4.12 : レム睡眠行動障害

During REM sleep, most voluntary muscles, such as those in the arms and legs, are temporarily paralyzed to prevent acting out dreams.

REM Sleep behavior disorder, also known as RBD, occurs when the muscles don't paralyze during REM sleep. 

Such individuals may display behaviors like kicking or shouting as if reacting to threats in their dreams, but they may have no memory of these actions.

RBD is often linked to neurodegenerative conditions like Parkinson's disease, making its early detection crucial for potentially diagnosing these conditions.

Commonly affecting men over 60, RBD can also appear in younger individuals and women.

Individuals with RBD are typically treated with drugs such as clonazepam, which calms the nervous system and helps prevent RBD episodes.

In addition, melatonin supplements may also be prescribed to stabilize sleep patterns.

Safety measures like padding the sharp corners of furniture and other objects in the bedroom are advised to prevent injury during sleep episodes.
