Unraveling the Mystery of Sleepwalking: Causes, Symptoms, and Management of a Common Sleep Disorder

Sleepwalking (somnambulism) is a common sleep disorder that occurs when individuals rise and move about while in a state of sleep. This phenomenon, also known as nocturnal wandering, is predominantly observed in children rather than adults. Many people wonder, “Is sleepwalking real?” The answer is yes, it’s a genuine sleep disorder that affects millions worldwide. Most children typically cease sleepwalking by adolescence. When sleepwalking episodes are infrequent, they generally don’t pose serious concerns or require medical intervention. However, frequent sleepwalking might indicate an underlying sleep-related disorder.


Adult sleepwalking is more frequently associated with, or manifests as part of, other sleep disorders. Various medical conditions can also trigger sleepwalking episodes in individuals. While some may be curious about how to sleepwalk, it’s important to note that it is not a voluntary action and should not be induced.


For households with sleepwalking members, implementing safety measures is crucial to prevent potential injuries during these episodes.

Symptoms of Sleepwalking

Understanding somnambulism symptoms is crucial for identifying and managing this sleep disorder. Sleepwalking typically occurs in the early hours of nighttime sleep — usually within 1 to 2 hours after falling asleep, during the deep sleep stage. While uncommon during naps, it remains possible. Episodes may occur rarely or frequently, typically lasting several minutes or potentially longer.


Sleepwalkers might:


• Rise from bed and walk around.
• Assume a sitting position with open eyes.
• Display a vacant, glassy-eyed expression.
• Be unresponsive to communication attempts.
• Show resistance to being awakened.
• Experience brief confusion upon waking.
• Have no recollection of sleepwalking the following morning.
• Experience daytime dysfunction due to sleep disruption.
• Experience concurrent sleep terrors involving screaming and limb movements.


In some instances, sleepwalkers may:


• Perform routine activities like dressing, speaking, or eating.
• Exit their residence.
• Operate vehicles.
• Engage in unusual behaviors, such as urinating in inappropriate places.
• Participate in unconscious sexual activities, a phenomenon known as sleepwalking sex.
• Sustain injuries from falls or window jumps.
• Display violent behavior during post-awakening confusion or occasional sleepwalking episodes.

When to see a doctor

Sporadic sleepwalking episodes typically don’t warrant concern and often resolve independently. These can be discussed during regular medical check-ups or pediatric visits.


Consult a healthcare provider if sleepwalking episodes:


• Occur frequently — such as multiple times weekly or several times nightly.
• Result in hazardous behavior or injuries to the sleepwalker or others.
• Disrupt household members’ or the sleepwalker’s sleep patterns.
• Cause significant daytime fatigue or interfere with daily activities, including school or work performance.
• Persist into adolescence or initially manifest in adulthood.

Causes

Understanding why people sleepwalk is essential for effective management. It falls under the classification of parasomnias — unwanted behaviors or events occurring during sleep. It’s categorized as an arousal disorder, occurring during N3 sleep, the deepest phase of non-rapid eye movement (non-REM) sleep. Sleep terrors, another non-REM sleep disorder, may accompany sleepwalking episodes.
What causes sleepwalking in the brain? It’s believed to be related to a partial awakening during the transition between sleep stages in the sleep cycle. This partial awakening can lead to confusional arousals, where the brain is caught between sleep and wakefulness.


Various triggers can contribute to its episodes, including:


• Insufficient sleep or poor sleep quality, leading to sleep deprivation.
• Heightened stress levels.
• Elevated body temperature.
• Changes in sleep patterns, traveling across time zones, or sleep disturbances.


Certain underlying sleep disorders may trigger sleepwalking behaviors, such as:


• Sleep-related breathing disorders — including conditions characterized by abnormal breathing patterns during sleep, particularly obstructive sleep apnea.
• Medication usage, specifically sleep aids, sedative medications, or certain psychiatric prescriptions.
• Consumption of alcoholic beverages. Alcohol can disrupt normal sleep patterns and increase its likelihood.
• Symptoms of restless leg syndrome.
• Chronic acid reflux or GERD.


Is it a sign of mental illness? While sleepwalking itself is not a mental illness, it can sometimes be associated with certain psychiatric conditions or stress-related disorders. However, most cases of sleepwalking are not linked to mental health issues.

Risk factors

Several factors may increase the likelihood of sleepwalking:


• Genetic predisposition and family history. It tends to have a hereditary component. The likelihood increases when one parent has experienced it, and significantly rises when both parents have a history of this sleep disorder.
• Developmental stage. Childhood sleepwalking is more common than sleepwalking in adults. Children experience it more frequently than adults. Adult-onset sleepwalking often indicates the presence of underlying medical conditions or sleep disorders.

Complications

While sleepwalking itself may not be problematic, it’s important to consider if it is dangerous. Individuals who sleepwalk might:


• Risk injury, particularly near obstacles, staircases, outdoor environments, while attempting to drive, or consuming inappropriate items during episodes. Injury prevention is crucial for sleepwalkers and their families.
• Experience prolonged sleep disruption, which can potentially lead to daytime fatigue and academic or behavioral challenges.
• Feel significant embarrassment about their actions.
• Interrupt others’ sleep patterns.
• In rare instances, potentially harm nearby individuals.

Diagnosis and Treatment

If it is causing significant problems, a doctor may recommend a sleep study to diagnose the condition and rule out other sleep disorders. During a sleep study, various aspects of your sleep are monitored, including brain waves, breathing, heart rate, and body movements.
For those wondering how to stop it, there are several treatment options available:

  1. Addressing underlying conditions: Treating any underlying sleep disorders or medical conditions that may be contributing to sleepwalking.
  2. Improving sleep hygiene: Establishing a regular sleep schedule, creating a relaxing bedtime routine, and ensuring a comfortable sleep environment can help reduce its episodes.
  3. Stress management: Since stress can trigger sleepwalking, stress-reduction techniques such as meditation or yoga may be beneficial.
  4. Cognitive behavioral therapy: This type of therapy can help address psychological factors that contribute to sleepwalking.
  5. Anticipated awakening: This technique involves waking the sleepwalker about 15-30 minutes before they typically sleepwalk, then allowing them to fall back asleep.
  6. Medication: In some cases, doctors may prescribe medications to help reduce its episodes.

Understanding its complexities from its causes to its potential dangers, is crucial for effective management and treatment of this sleep disorder. Whether dealing with childhood sleepwalking or adult-onset cases, recognizing the symptoms and underlying factors can help in seeking appropriate medical advice and implementing necessary safety measures.
