Definition of Sleep Walking

Sleepwalking, also known as somnambulism, is a sleep disorder that involves performing various activities while in a state of deep sleep. People who sleepwalk typically move or perform activities as if they were awake, but they are actually asleep and usually have no memory of the event afterward.

Sleepwalking episodes can vary in duration and complexity. Some individuals may simply sit up in bed, while others might walk around the house, perform routine tasks, or even leave the house and engage in complex behaviors without being aware of their actions.

Sleepwalking usually occurs during the non-REM (rapid eye movement) stage of sleep, usually within the first few hours after falling asleep. Factors like sleep deprivation, stress, fever, medications, underlying sleep disorders, or genetics can contribute to sleepwalking tendencies. While sleepwalking itself may not be harmful, there is a risk of injury due to the unawareness of surroundings and potential engagement in hazardous activities during episodes.

History of Sleep Walking

Sleepwalking has been documented throughout history, with mentions in ancient texts and folklore across various cultures. Here’s a brief overview of its historical aspects:\

Ancient References:

References to sleepwalking can be found in ancient texts. For instance, in ancient Roman and Greek texts, there are descriptions of individuals experiencing sleepwalking episodes. Roman physician Galen and Greek philosopher Aristotle discussed sleepwalking in their writings, attributing it to an imbalance in bodily fluids.

Middle Ages and Supernatural Beliefs:

During the Middle Ages, sleepwalking was often associated with supernatural or spiritual explanations. It was sometimes linked to possession or demonic influence, leading to various superstitions and beliefs.

18th and 19th Centuries:

As scientific inquiry progressed, there was a shift in understanding sleepwalking from being purely supernatural to a physiological phenomenon. Medical professionals started exploring sleep disorders more systematically. Sleepwalking was recognized as a sleep disorder rather than a supernatural occurrence.

20th Century and Beyond:

With advancements in sleep research and technology, scientists gained a better understanding of the sleep cycle and associated disorders. Sleepwalking was classified as a parasomnia, a category of sleep disorders characterized by abnormal movements, behaviors, emotions, perceptions, and dreams during sleep.

Researchers have identified various triggers and contributing factors to sleepwalking, including genetics, stress, sleep deprivation, medications, and other underlying sleep disorders. Treatment methods and interventions have evolved over time to manage and reduce the occurrence of sleepwalking episodes.

Throughout history, sleepwalking has been a subject of fascination and mystery, often depicted in literature, art, and media as a curious and sometimes eerie phenomenon. However, scientific understanding and advancements in sleep medicine have helped demystify sleepwalking to a large extent, providing insights into its causes and potential treatments.

DSM-5 Criteria of Sleep Walking

In the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), sleepwalking is categorized under the umbrella of “Non-Rapid Eye Movement (NREM) Sleep Arousal Disorders.” The DSM-5 outlines specific criteria for diagnosing sleepwalking disorder, which includes:

A. Recurrent episodes of incomplete awakening from sleep, usually occurring during the first third of the major sleep episode, and accompanied by the following:

Sleepwalking, which may range from simply sitting up in bed to walking around or performing complex activities.

The individual is difficult to awaken during the episode.

Amnesia for the episode.

B. The episodes cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.

C. The disturbance is not attributable to the physiological effects of a substance (e.g., a drug of abuse, a medication) or another medical condition.

D. Coexisting mental disorders and medical conditions do not adequately explain the episodes of sleepwalking.

E. The disturbance is not better explained by another sleep disorder, such as sleep-related seizure disorder, nightmares, panic attacks, or REM sleep behavior disorder.

It’s important to note that the DSM-5 provides criteria to help mental health professionals diagnose various disorders, including sleepwalking disorder. A diagnosis should be made by a qualified healthcare professional based on a comprehensive evaluation of an individual’s symptoms, history, and any potential underlying causes or contributing factors.

Etiology of Sleep Walking

The exact causes of sleepwalking (somnambulism) are not entirely understood, but several factors and potential contributors have been identified:

Genetics:

There appears to be a genetic component to sleepwalking, as it often runs in families. If a parent has a history of sleepwalking, their children are more likely to experience it as well.

Sleep Disruption or Fragmentation:

Certain disturbances in the sleep cycle, such as sleep deprivation, irregular sleep schedules, or interrupted sleep, can increase the likelihood of sleepwalking episodes.

Medical Conditions:

Some medical conditions can contribute to sleepwalking. These include fever, sleep apnea, restless leg syndrome, gastroesophageal reflux disease (GERD), and psychiatric disorders like anxiety or PTSD.

Medications:

Certain medications, particularly those that affect the central nervous system, may trigger sleepwalking episodes. Examples include sedative-hypnotics, certain antidepressants, antipsychotics, and stimulants.

Stress and Fatigue:

Emotional stress, anxiety, or extreme fatigue can increase the likelihood of sleepwalking.

Developmental Factors:

Sleepwalking is more common in children and tends to decrease as they age. It is more prevalent in younger individuals, especially between the ages of 4 and 8, but can persist or begin in adulthood as well.

Sleep Disorders:

Conditions like sleep apnea, restless leg syndrome, and insomnia might be associated with an increased likelihood of sleepwalking.

Sleepwalking often occurs during the non-REM (NREM) sleep stages, particularly during the transition from deeper stages to lighter stages of sleep. Disruptions in this transition process can lead to incomplete arousals, triggering sleepwalking episodes.

Understanding the specific causes and triggers for an individual’s sleepwalking can often involve a detailed assessment by a healthcare professional. Identifying and addressing underlying factors, such as improving sleep hygiene, managing stress, or treating any associated sleep disorders, can help reduce the frequency and severity of sleepwalking episodes.

Theories related to Sleep Walking

Several theories have been proposed to explain the occurrence of sleepwalking (somnambulism). While none fully elucidates the phenomenon, these theories offer insights into potential mechanisms:

Physiological Factors:

Some researchers believe that sleepwalking may arise due to the brain’s incomplete transition between different stages of sleep, particularly between deep sleep (non-REM) and wakefulness. Disruptions in this transition can cause partial arousals, leading to sleepwalking behaviors.

Genetic Predisposition:

Studies have suggested a genetic component to sleepwalking. Individuals with a family history of sleepwalking are more likely to experience it themselves, indicating a potential genetic predisposition to the disorder.

Central Nervous System (CNS) Arousal Mechanisms:

Sleepwalking could involve malfunctioning arousal systems in the brain. The intricate balance between sleep and wake states might be disrupted, leading to motor behaviors characteristic of sleepwalking.

Sleep Deprivation and Fatigue:

Sleep deprivation or irregular sleep patterns may trigger sleepwalking episodes. When the body and brain are overly tired or fatigued, it might disrupt the usual sleep cycles, increasing the likelihood of sleepwalking.

Environmental and Psychosocial Triggers:

Stressful life events, anxiety, or emotional distress can be associated with an increased incidence of sleepwalking. These factors might disrupt sleep patterns and increase the chances of sleepwalking episodes.

Brain Development and Maturation:

Sleepwalking is more common in children and tends to decrease with age. It may be related to brain maturation, with the disorder diminishing as the brain matures and sleep patterns stabilize.

Neurochemical Imbalance:

Some researchers suggest that imbalances in neurotransmitters or neurochemicals in the brain could play a role in sleepwalking. Changes in the levels of certain neurotransmitters involved in sleep regulation might contribute to abnormal sleep behaviors.

Understanding these theories helps in exploring potential mechanisms underlying sleepwalking. However, it’s important to note that sleepwalking is a complex phenomenon, and a combination of factors—genetic, environmental, physiological, and psychological—likely contribute to its occurrence. Further research is necessary to fully comprehend the intricate mechanisms involved in sleepwalking.

Risk factors of Sleep Walking

Several risk factors can increase the likelihood of experiencing sleepwalking episodes. These include:

Family History:

Individuals with a family history of sleepwalking are more likely to experience it themselves. There appears to be a genetic predisposition to sleepwalking, suggesting a hereditary component to the disorder.

Age:

Sleepwalking is more prevalent in children, especially between the ages of 4 and 8, but it can occur in adults as well. It tends to decrease with age as the brain matures and sleep patterns stabilize.

Sleep Deprivation and Fatigue:

Lack of adequate sleep or irregular sleep patterns can disrupt the normal sleep-wake cycle, increasing the chances of experiencing sleepwalking episodes.

Stress and Anxiety:

Emotional stress, anxiety, or psychological distress can contribute to sleep disturbances and trigger sleepwalking in susceptible individuals.

Certain Medications:

Some medications, particularly those that affect the central nervous system or sleep patterns, may increase the likelihood of sleepwalking. These might include sedative-hypnotics, certain antidepressants, antipsychotics, and stimulants.

Sleep Disorders:

Conditions such as sleep apnea, restless leg syndrome, or insomnia might be associated with an increased risk of sleepwalking.
