Sleep Disorders in Children and Adolescents
Sleep disorders in children and adolescents encompass a range of conditions that affect the quality, duration, and patterns of sleep. These difficulties can interfere with daily functioning and overall development and may significantly affect a child’s emotional and social well-being.
General DSM-5 Criteria for Sleep Disorders
Depending on the specific sleep disorder, clinical features may include:
• Persistent difficulties with sleep initiation, maintenance, duration, timing, or quality.
• Sleep disturbances that occur frequently and persist over time.
• Clinically significant distress or impairment in social, academic, behavioral, or other important areas of functioning.
• Symptoms that are not better explained by the physiological effects of a substance, another sleep disorder, or another medical or mental health condition.
Specific diagnostic criteria, including frequency and duration requirements, vary according to the individual sleep-wake disorder.
Nightmare Disorder
What is Nightmare Disorder?
Nightmare Disorder is characterized by repeated episodes of vivid, disturbing, and frightening dreams, typically occurring during rapid eye movement (REM) sleep. The child may awaken feeling anxious or frightened and may have difficulty returning to sleep. Unlike some other parasomnias, the individual becomes fully alert upon awakening and is usually able to recall the content of the dream in detail.
DSM-5 Criteria
• Repeated occurrences of extended, extremely dysphoric, and well-remembered dreams, typically involving threats to survival, security, or physical integrity.
• Upon awakening from the disturbing dreams, the individual rapidly becomes alert and oriented.
• The sleep disturbance causes clinically significant distress or impairment in social, academic, behavioral, or other important areas of functioning.
• The symptoms are not attributable to the physiological effects of a substance.
• Coexisting mental or medical conditions do not adequately explain the symptoms.
Etiology
Nightmares may be associated with emotional stress, traumatic experiences, anxiety, or significant stressful events in a child’s life. Genetic and individual vulnerability factors may also influence the tendency to experience recurrent nightmares.
Prognosis
Nightmares are relatively common during childhood and often decrease in frequency with age. When symptoms are persistent or significantly interfere with sleep and daytime functioning, appropriate psychological intervention and support can help reduce their frequency and severity.
Treatment
Relaxation Techniques: Relaxation strategies before bedtime may help reduce anxiety and physiological arousal.
Cognitive Behavioral Therapy (CBT): CBT-based approaches can help children manage anxiety and fears associated with nightmares. Specific techniques, such as imagery rehearsal therapy, may also be useful for recurrent nightmares.
Sleep Routine Modification: Establishing a consistent and calming bedtime routine and limiting exposure to frightening or overstimulating content before sleep may improve sleep quality.
Sleep Terror Disorder
What are Sleep Terrors?
Sleep terrors involve recurrent episodes of abrupt arousal from sleep accompanied by intense fear and autonomic activation. They typically occur during deep non-REM (NREM) sleep, particularly during the first third of the night. During an episode, the child may scream, appear terrified, breathe rapidly, or show other signs of intense fear while remaining only partially awake.
Unlike nightmares, children experiencing sleep terrors usually have little or no recollection of the episode afterward and may be difficult to comfort or communicate with during the event.
DSM-5 Criteria
• Recurrent episodes of incomplete awakening from sleep, usually occurring during the first third of the major sleep period and typically beginning with a panicked scream.
• Intense fear and signs of autonomic arousal, such as rapid heart rate, rapid breathing, sweating, or dilated pupils.
• Relative unresponsiveness to attempts by others to comfort the individual during the episode.
• Little or no dream imagery is recalled.
• Amnesia for the episode is typically present.
• The episodes cause clinically significant distress or impairment in important areas of functioning.
• The symptoms are not attributable to a substance, medication, or another medical or mental health condition.
Etiology
Factors associated with sleep terrors may include genetic predisposition, sleep deprivation, excessive fatigue, emotional stress, irregular sleep schedules, and unfamiliar sleeping environments. Other sleep disturbances may also contribute to episodes in susceptible children.
Prognosis
Sleep terrors are most common in younger children and frequently resolve spontaneously as the child grows older. Episodes generally become less frequent with age and are considerably less common in adulthood.
Treatment
Consistent Bedtime Routine: Maintaining an adequate and regular sleep schedule can help reduce episodes, particularly when sleep deprivation is a contributing factor.
Stress Management: Identifying and addressing sources of stress or anxiety may help reduce the frequency of episodes.
Parental Education and Support: Helping parents understand the benign nature and typical course of sleep terrors can reduce anxiety and improve management of episodes at home.
Sleepwalking (Somnambulism)
What is Sleepwalking?
Sleepwalking, or somnambulism, is a NREM parasomnia characterized by episodes in which an individual gets out of bed and walks or performs other activities while remaining in a state of incomplete awakening from sleep. Episodes typically occur during deep NREM sleep, particularly during the first third of the night.
During an episode, the individual may have a blank or staring facial expression, show reduced responsiveness to others, and be difficult to awaken. There is usually little or no memory of the event afterward.
DSM-5 Criteria
• Recurrent episodes of incomplete awakening from sleep, typically involving getting out of bed and walking around.
• During the episode, the individual has a blank, staring face and is relatively unresponsive to attempts by others to communicate.
• The individual can be awakened only with considerable difficulty.
• There is little or no recollection of the episode afterward.
• Within several minutes after awakening, there is generally no persistent impairment of mental activity or behavior.
• The episodes cause clinically significant distress or impairment in social, academic, behavioral, or other important areas of functioning.
• The disturbance is not attributable to the physiological effects of a substance, medication, or another medical or mental health condition.
Etiology
Sleepwalking is associated with a combination of genetic and environmental factors. Sleep deprivation, irregular sleep schedules, emotional stress, fever, and certain medications or substances may increase the likelihood of episodes in susceptible individuals. Sleepwalking is particularly common during childhood, although it can also occur in adolescents and adults.
Prognosis
Sleepwalking is relatively common during childhood and often decreases or resolves with age. Persistent or newly occurring sleepwalking during adolescence or adulthood may warrant further assessment for contributing sleep, medical, psychological, or medication-related factors.
Treatment
Safety Measures: Ensuring a safe sleeping environment is essential. Measures may include securing windows and doors, removing potentially dangerous objects, and reducing the risk of falls or other injuries.
Sleep Hygiene and Relaxation: Maintaining adequate sleep duration, a consistent sleep schedule, and strategies to reduce stress may decrease the frequency of episodes.
Scheduled Awakenings: In children with frequent episodes occurring at predictable times, scheduled awakenings may sometimes be helpful.
Medication: Pharmacological treatment is generally reserved for severe, persistent, or potentially dangerous cases. When necessary, treatment should be individualized and undertaken under specialist medical supervision.
Conclusion
Sleep disorders represent an important aspect of the mental and physical health and development of children and adolescents. Accurate assessment is important because sleep disturbances may arise from a variety of behavioral, psychological, neurological, respiratory, or medical factors. Early identification, appropriate intervention, and ongoing family support can contribute significantly to improving sleep quality, daytime functioning, and overall well-being.
