Why does sleepwalking occur during REM?

During the stage called rapid eye movement (REM) sleep, the eyes move quickly and vivid dreaming is most common. Each night, people go through several cycles of non-REM and REM sleep. Sleepwalking (somnambulism) most often occurs during deep, non-REM sleep (called N3 sleep) early in the night.

What stage of sleep are sleepwalkers in?

Sleepwalking is a disorder of arousal, meaning it occurs during N3 sleep, the deepest stage of non-rapid eye movement (NREM) sleep. Another NREM disorder is sleep terrors, which can occur together with sleepwalking.

How is sleepwalking different from REM sleep?

The difference between sleepwalking and RBD is subtle, but important: sleepwalking typically takes place in non-REM and transitional stages of sleep, whereas RBD takes place during REM (rapid-eye-movement) sleep.

What is happening in the brain during sleepwalking?

Scientists believe sleepwalking occurs when two areas of the brain — the limbic region of the brain that deals with raw emotions and the area of the cortex that manages complex motor activity — remain awake while the areas that would otherwise mitigate their primitive impulses — notably the frontal cortex (rationality) …

Is sleepwalking a REM behavior disorder?

During typical REM sleep, your muscles are temporarily paralyzed while your brain is actively dreaming. In some cases, the chemical that causes your body to remain still and your brain to remain active doesn’t function properly. As a result, you can develop disorders such as sleepwalking, narcolepsy, or RBD.

What Is REM disorder?

Rapid eye movement (REM) sleep behavior disorder is a sleep disorder in which you physically act out vivid, often unpleasant dreams with vocal sounds and sudden, often violent arm and leg movements during REM sleep — sometimes called dream-enacting behavior.
