Sleepwalking Information

Sleepwalking definition and facts

  • Sleepwalking is relatively common in younger children and the frequency is much less in adolescents.
  • Although disruptive and frightening for parents in the short-term, sleepwalking is not associated with long-term complications.
  • Factors predisposing to sleepwalking are genetic influences, environmental influences, and physiologic factors.
  • The diagnosis of sleepwalking with history and exam. Laboratory or radiological studies rarely are necessary.
  • Several conditions are similar to sleepwalking so the doctor will need to eliminate them in order to diagnose sleepwalking.
  • There are treatments options to consider when dealing with a child who sleepwalks.
  • The outlook for resolution of the disorder is excellent.

How can you prevent sleepwalking?

  • Avoid the use of alcohol or central nervous system depressants if prone to sleepwalking.
  • Avoid fatigue or insomnia, because this can instigate an episode of sleepwalking.
  • Avoid or minimize stress, anxiety, and conflict, which can worsen the condition.

How do you stop sleepwalking? What is the treatment or cure?

Sleepwalking Home RemediesA person who has a sleepwalking disorder can take the following measures:

  • get adequate sleep;
  • meditate or do relaxation exercises;
  • avoid any kind of stimuli (auditory or visual) prior to bedtime;
  • keep a safe sleeping environment, free of harmful or sharp objects;
  • sleep in a bedroom on the ground floor if possible to prevent falls and avoid bunk beds;
  • lock the doors and windows;
  • remove obstacles in the room, tripping over toys or objects is a potential hazard;
  • cover glass windows with heavy drapes; and
  • place an alarm or bell on the bedroom door and if necessary on any windows.
Medical treatmentsSleepwalking may be associated with an underlying medical condition, for example, gastroesophageal reflux disease (GERD), obstructive sleep apnea, periodic leg movements (restless leg syndrome), or seizures. To help prevent sleepwalking, underlying medical condition should be treated.Medications for the treatment of sleepwalking disorder may be necessary in the following situations:
  • when the possibility of injury is real;
  • when continued behaviors are causing significant family disruption or excessive daytime sleepiness; and
  • when other measures have proven to be inadequate.
MedicationsBenzodiazepines, such as estazolam (ProSom), or tricyclic antidepressants, such as trazodone (Desyrel), have been shown to be useful. Clonazepam (Klonopin) in low doses before bedtime and continued for three to 6 weeks is usually effective.Medication can often be discontinued after three to 5 weeks without recurrence of symptoms. Occasionally, the frequency of episodes increases briefly after discontinuing the medication.Other remediesRelaxation techniques, mental imagery, and anticipatory awakenings are preferred for long-term treatment of persons with sleepwalking disorder.
  • Relaxation and mental imagery should be undertaken only with the help of an experienced behavioral therapist or hypnotist.
  • Anticipatory awakenings consist of waking the child or person approximately 15-20 minutes before the usual time of an event, and then keeping him or her awake through the time during which the episodes usually occur.

What are symptoms of sleepwalking? How can you tell if they are sleepwalking?

Following are examples of symptoms of sleepwalking.

  • Episodes range from quiet walking around the room to agitated running or attempts to "escape." The person sleepwalking may appear clumsy and dazed in his or her behavior.
  • Typically, the eyes are open with a glassy, staring appearance as the person quietly roams around the house. They do not, however, walk with their arms extended in front of them as is inaccurately depicted in movies.
  • On questioning the person sleepwalking, responses are slow with simple thoughts, contain nonsense phraseology or absent responses. If the person is returned to bed without awakening, they usually do not remember the event.
  • Older children, who may awaken more easily at the end of an episode, often are embarrassed by the behavior (especially if it was inappropriate). In lieu of walking, some children perform repeated behaviors (such as straightening their pajamas). Bedwetting may also occur.
  • Sleepwalking is not associated with previous sleep problems, sleeping alone in a room or with others, fear of the dark (achluophobia), or anger outbursts.
  • Some studies suggest that children who sleepwalk may have been more restless sleepers between the ages of four and five, and more restless with more frequent awakenings during the first year of life.

What are the complications of sleepwalking?

A common complication is injury sustained during sleepwalking activities.

What causes sleepwalking?

Sleepwalking seems to be associated with inherited (genetic), environmental, physiologic, and medical factors.Genetic factorsOne study documented that sleepwalking is ten times more likely to occur if a first-degree relative has a history of sleepwalking.Environmental factorsSleep deprivation, chaotic sleep schedules, fever, stress, magnesium deficiency, and alcohol intoxication can trigger sleepwalking. Drugs, for example, sedative/hypnotics (drugs that promote sleep), neuroleptics (drugs used to treat psychosis), minor tranquilizers (drugs that produce a calming effect), stimulants (drugs that increase activity), and antihistamines (drugs used to treat symptoms of allergies) associated with an increased likelihood of sleepwalking.Physiologic factorsPhysiologic factors that may contribute to sleepwalking include:

  • The length and depth of slow wave sleep (states III and IV of non-REM sleep). These stages are more commonly seen in younger children and thus may explain the age differences in the frequency of sleepwalking.
  • Conditions such as pregnancy and menstruation are known to increase the frequency of sleepwalking.
  • Arrhythmias (abnormal heart rhythms)
  • Fever
  • Gastroesophageal reflux (acid reflux - food or liquid regurgitating from the stomach into the food pipe)
  • Nghttime asthma
  • Nighttime seizures (convulsions)
  • Obstructive sleep apnea (condition in which breathing stops temporarily while sleeping)
  • Psychiatric disorders, for example, posttraumatic stress disorder, panic attacks, or dissociative states (for example, multiple personality disorder)

What do you do when someone is sleepwalking? Should you wake them up?

One common misconception is that a person sleepwalking should not be awakened. It is not dangerous to awaken a sleepwalker, although it is common for the person to be confused or disoriented for a short time when awake. Another misconception is that a person cannot be injured while sleepwalking. Injuries caused by sleepwalking, for example, tripping and loss of balance, are common.

What is sleepwalking?

Sleepwalking is characterized by a complex action behavior (walking) during sleep. Occasionally, the person may talk, but it does not make sense. The person's eyes are commonly open, but have a characteristic glassy "look right through you" character.Sleepwalking most commonly occurs during early childhood and less commonly during adolescence.

What is the prognosis of sleepwalking?

Sleepwalking may or may not reduce with age, as described above. It usually does not indicate a serious disorder, although it can be a symptom of other disorders.

What other sleep conditions have similar symptoms of sleepwalking?

Sleepwalking, night terrors, and confusional arousals are all related, common non-REM sleep disorders that tend to overlap in some of their symptoms. Approximately 15%-20% of young children through mid-adolescence will experience some or all of these behaviors. Moreover, seizures occurring during sleep (nocturnal seizures) can cause movement disorder during sleeping.Night terrors: Like sleepwalking night terrors tend to occur during the first half of a night's sleep - often within 30 to 90 minutes from falling asleep. Also like sleepwalking, they occur during stage III of non-REM sleep. However, unlike sleepwalking, an individual with night terrors will portray a sudden and often agitated arousal that may appear to parents as violent and terrified behaviors. During such an episode, the child characteristically will not be comforted by an embrace from a parent or caregiver.Night terrors often start during the toddler years with peak incidence between five and seven years of age. During these times evidence of a surge in autonomic nervous system activity is evident. Accelerated heart and respiratory rates, dilated pupils, and sweating are characteristic.Triggers for night terrors may include sleep deprivation, stress, and medications (stimulants, sedatives, antihistamines, etc). Unlike sleepwalking, episodes of night terrors may recur for several weeks in a row, abate completely, and later return.Confusional arousals: Similar to night terrors, confusional arousals are characterized by a sudden and violent arousal from sleep with behaviors described as agitated and semi-purposeful in pattern. Speech is generally coherent (unlike sleepwalking). A distinguishing point between night terrors and confusional arousals is the lack of autonomic nervous system (accelerated heart/respiratory rates, dilated pupils, sweating) phenomena in the latter. Confusional arousals tend to occur during the first half of a night's sleep (during stage II non-REM sleep). They are characteristically short-lived, lasting 5 to 15 minutes but can last up to 30 minutes in duration. Amnesia for the event is characteristic.Nocturnal seizures: Several important differential points help delineate the above three sleep behaviors from seizure activity. Seizures by their nature are very brief, often lasting only a few minutes. In addition, seizure events are likely to be confused with the above; and are characterized by a series of repeated, stereotypical, and frequent behaviors occurring in clusters. Moreover, seizures more commonly occur in the second half of the night's sleep. Patients often will have postictal (symptoms after the seizure) complications such as headache, extreme grogginess, hard to arouse, as well as incontinence of urine and stool. To assist in establishing a correct diagnosis a neurologist may perform a video-EEG study to help clarify the issue. Home videos taken on a smart phone are often very helpful in establishing the diagnosis.

What tests diagnose sleepwalking?

Usually, no exams and tests are necessary. However, a medical evaluation may be completed to rule out medical causes of sleepwalking. Occasionally, a psychological evaluation can determine whether excessive stress or anxiety is the cause of sleepwalking. Sleep study tests may be done in persons in whom the diagnosis is still unclear.

When should you call your health care professional about sleepwalking?

Sleepwalking usually does not require a visit to your healthcare professional. However, the condition should be discussed with your healthcare professional if sleepwalking:

  • is accompanied by other symptoms,
  • is frequent or persistent, or
  • includes potentially dangerous activities (such as driving).
  • If you have any history of strange activity or sleepwalking while taking medications for insomnia like zolpidem (Ambien), you should also speak to your physician.

Why do people walk in their sleep?

Sleepwalking has been described in medical literature dating before Hippocrates (460 BC-370 BC). In Shakespeare's tragic play, Macbeth, Lady Macbeth's famous sleepwalking scene ("out, damned spot") is ascribed to her guilt and resulting insanity as a consequence of her involvement in the murder of her father-in-law.Parasomnias are a group of sleep behaviors common in in children, teens, and occasionally adults. To understand parasomnias, it is helpful to understand the physiology of sleep.Sleep occurs in two broad categories defined by characteristic changes during an EEG (electro encephalogram, “brain wave test”). The two categories are REM (rapid eye movement) and non-REM (NREM) sleep cycles. Non-REM sleep has four “levels” characterized by unique patterns of the EEG.

  • Stage I: introduction to sleep during which there is generalized muscle relaxation and effort is required to keep your eyes open.
  • Stage II: beginning to sleep (light sleep)
  • Stage III and IV: deep sleep
  • REM sleep: associated with dreaming
An entire sleep cycle from Stage I (non-REM) thru REM sleep lasts between 90 and-120 minutes and repeats 4 to 5 times during the sleep experience. Each “level” of non-REM and REM sleep last between 5 to 15 minutes. A large Canadian study reviewed sleep patterns of children aged 2.5 to 6 years and discovered approximately 88% of them experienced parasomnias, and 15% were sleepwalkers. Other signs and symptoms associated with sleepwalking were: (1) sleep terrors (40%), (2) sleep enuresis (bedwetting, 25%), (3) bruxism (grinding of the teeth, 46%), and rhythmic movements (such as head banging, 9%).Sleepwalking characteristically occurs during the first or second sleep cycles, specifically, during stages III and IV, otherwise known as deep sleep. Due the short time frame involved, sleepwalking tends not to occur during naps.Sleepwalking activity may include simply sitting up and appearing awake while remaining asleep, getting up and walking around, or complex activities such as moving furniture, going to the bathroom, dressing and undressing, and similar activities. Some people even drive a car while actually asleep. The episode can be very brief (a few seconds or minutes) or can last for 30 minutes or longer.Upon waking, the sleepwalker has no memory of his or her behaviors.
