1. What is Sleepwalking (Somnambulism)?

Sleepwalking, clinically known as somnambulism, is a sleep disorder that causes people to get up and move around while still asleep. It falls under the category of parasomnias, which are unusual behaviors that occur during sleep. While sleepwalking is more commonly observed in children, it can also affect adults. Understanding the basics of sleepwalking can help in identifying the symptoms and seeking appropriate care.

Sleepwalking episodes usually occur during the deep stages of non-rapid eye movement (NREM) sleep, typically in the first few hours after falling asleep. During these episodes, individuals may perform a variety of actions, ranging from simple tasks like sitting up in bed to more complex activities like walking around the house, going outside, or even driving a car.

Here’s a breakdown of what constitutes sleepwalking:

• Definition: Sleepwalking is a state of altered consciousness where a person performs activities while in a sleep state.
• Timing: It usually occurs during the deep NREM sleep stages, particularly stage N3.
• Activities: Activities can range from simple movements to complex behaviors.
• Amnesia: Individuals often have no memory of the sleepwalking episode upon waking.

Sleepwalking can sometimes be associated with other sleep disorders, such as sleep terrors, which can occur simultaneously. It’s also important to differentiate sleepwalking from other nocturnal behaviors like night eating syndrome or REM sleep behavior disorder, as the causes and treatments may vary.

2. What Are the Common Symptoms of Sleepwalking?

Recognizing the symptoms of sleepwalking is crucial for early detection and management. The signs can vary in intensity and complexity, but some common indicators include:

• Getting out of bed and walking around: This is the most obvious symptom.
• Sitting up in bed with eyes open: The person may appear awake but is still asleep.
• Having a glazed, glassy-eyed expression: This is a typical characteristic during an episode.
• Being unresponsive to communication: Attempts to talk to the person may be futile.
• Difficulty waking up: The sleepwalker may be hard to rouse and disoriented if awakened.
• Confusion after waking: Upon waking, the person may be confused about their surroundings or how they got there.
• Lack of memory of the event: The individual typically doesn’t remember sleepwalking.
• Daytime fatigue: Disturbed sleep can lead to excessive tiredness during the day.

In some cases, sleepwalking can involve more complex behaviors, such as:

• Performing routine activities: This might include getting dressed, eating, or talking.
• Leaving the house: This can be dangerous if the person is unaware of their surroundings.
• Driving a car: A rare but potentially life-threatening occurrence.
• Engaging in unusual behavior: Examples include urinating in inappropriate places.
• Participating in sexual activity without awareness: This can lead to legal and ethical issues.
• Injuring oneself: Risks include falling, bumping into objects, or jumping out of windows.
• Becoming violent: Rarely, the person may become aggressive when awakened or during the episode.

If you or someone you know exhibits these symptoms, consulting a healthcare professional is advisable. You can also find resources and expert opinions on WHY.EDU.VN.
