Should I wake a sleepwalker?

Try not to wake them abruptly, as they may be confused and react aggressively. Instead, gently guide them by the arm back to their bed.

Can sleepwalking be a sign of a mental illness?

In children, no. In adults, it can occasionally be triggered by high stress or anxiety, but it is primarily a sleep-stage transition disorder.

Is there a cure for sleepwalking?

There is no 'cure,' but most cases can be effectively managed through better sleep hygiene and safety precautions, and most children outgrow it.

Sleepwalking (Somnambulism) | whataresleepdisorders.com

Sleepwalking, formally known as somnambulism, is a parasomnia that involves getting up and walking around while still in a state of deep sleep. It most commonly occurs during the N3 stage of Non-REM sleep, usually within the first few hours after falling asleep. While the sleepwalker may have their eyes open and can navigate around objects, they are not conscious in the traditional sense.

The behaviors during sleepwalking can range from simple sitting up in bed to complex activities like walking through the house, opening doors, or even trying to drive a car. Most sleepwalkers have no memory of the event upon waking, which can be disorienting and distressing for both the individual and their family.

Why Does Sleepwalking Happen?

Sleepwalking occurs when the brain is partially aroused from deep sleep but remains in a sleep state. This 'dissociated' state means the motor cortex (which controls movement) is active, while the parts of the brain responsible for conscious awareness and memory remain 'offline.'

There is a strong genetic component; if both parents have a history of sleepwalking, their children have a 60% chance of developing the condition. Other common triggers include severe sleep deprivation, fever, stress, and certain medications like sedatives or antihistamines.

Common Behaviors and Red Flags

A sleepwalker might have a glazed, 'staring' look in their eyes. They may be non-responsive to questioning or may mumble incoherent phrases. While many episodes are brief and harmless, some sleepwalkers may engage in inappropriate behaviors, such as urinating in a closet or trying to leave the house.

The primary danger of sleepwalking is physical injury. Falling down stairs, walking out into traffic, or handling kitchen appliances while asleep are serious risks. Identifying these red flags early is important for implementing safety measures.

Diagnosis and Evaluation

In most cases, a diagnosis can be made based on descriptions from family members. However, if the sleepwalking starts in adulthood or involves violent behavior, a doctor may recommend an overnight sleep study (polysomnography) to rule out other conditions like REM Sleep Behavior Disorder or nocturnal seizures.

Adult-onset sleepwalking is more likely to be associated with an underlying medical condition, a specific medication, or a mental health issue, whereas childhood sleepwalking is often a normal part of neurological development.

Managing and Preventing Episodes

The most effective way to prevent sleepwalking is to maintain a consistent sleep schedule and ensure adequate sleep duration. Sleep deprivation is the #1 trigger for 'rebound' deep sleep, which makes sleepwalking more likely. Stress management and avoiding alcohol before bed also significantly reduce the frequency of episodes.

For those with frequent episodes, 'scheduled awakenings' can be effective. This involves waking the person about 15-20 minutes before their typical sleepwalking event occurs, then letting them fall back asleep. This resets the sleep cycle and can prevent the partial arousal from deep sleep.

When to Speak With a Doctor

Consult a doctor if sleepwalking occurs frequently, leads to dangerous behaviors, or starts for the first time in an adult.
