ICD-10: G47.5

Parasomnia, classified under ICD-10 code G47.5, encompasses a range of sleep disorders characterized by abnormal behaviors, movements, emotions, perceptions, and dreams that occur during sleep. This classification is crucial for healthcare providers in diagnosing and treating patients experiencing these disturbances.

Clinical Description of Parasomnia

Parasomnias are primarily categorized into two types: NREM-related parasomnias and REM-related parasomnias. Each type presents distinct clinical features and implications for patient management.

NREM-Related Parasomnias

NREM-related parasomnias occur during non-rapid eye movement (NREM) sleep, typically in the first third of the night. Common examples include:

• Sleepwalking (Somnambulism): Characterized by complex behaviors while in a state of partial arousal, individuals may walk, talk, or perform other activities while appearing asleep. They typically have no memory of the event upon waking.
• Sleep Terrors (Night Terrors): These episodes involve sudden arousal from sleep, accompanied by intense fear, screaming, and autonomic responses such as increased heart rate. Unlike nightmares, individuals usually do not recall the episode.
• Confusional Arousals: These occur when a person wakes up in a confused state, often with disorientation and difficulty in responding to questions.

REM-Related Parasomnias

REM-related parasomnias occur during rapid eye movement (REM) sleep, which is when most dreaming occurs. Key examples include:

• REM Sleep Behavior Disorder (RBD): This disorder involves the acting out of dreams, which can lead to injury to the individual or their bed partner. Patients may exhibit vigorous movements, shouting, or even violent behavior during episodes.
• Nightmares: Disturbing dreams that cause awakening and significant distress. Unlike sleep terrors, individuals typically remember the content of their nightmares.

Diagnosis and Assessment

The diagnosis of parasomnia typically involves a comprehensive clinical evaluation, including:

• Patient History: Detailed accounts of sleep patterns, behaviors during sleep, and any associated injuries or disturbances.
• Polysomnography (Sleep Study): This diagnostic tool records brain waves, oxygen levels, heart rate, and breathing, providing insights into sleep stages and identifying abnormal behaviors during sleep.

Treatment Options

Management of parasomnias varies based on the type and severity of the disorder. Common approaches include:

• Behavioral Interventions: For conditions like sleepwalking, ensuring a safe sleep environment and implementing strategies to minimize triggers can be effective.
• Medications: In cases of severe RBD or frequent night terrors, medications such as clonazepam or melatonin may be prescribed to help regulate sleep patterns.
• Cognitive Behavioral Therapy (CBT): This can be beneficial for individuals experiencing nightmares, particularly if they are linked to anxiety or trauma.

Conclusion

ICD-10 code G47.5 for parasomnia encompasses a variety of sleep disorders that can significantly impact an individual's quality of life. Understanding the clinical features, diagnostic criteria, and treatment options is essential for healthcare providers to effectively manage these conditions. Early intervention and tailored treatment plans can help mitigate the effects of parasomnias, improving overall sleep health and well-being for affected individuals.

3. REM Sleep Behavior Disorder (RBD): In this condition, individuals act out their dreams, which can lead to violent movements and potential injury. Patients may recall their dreams vividly.

4. Sleep Talking (Somniloquy): This involves speaking during sleep without awareness, which can range from simple sounds to complex conversations.

5. Sleep-related Eating Disorder: This disorder involves episodes of eating while in a state of sleep, often with no memory of the event.

Signs and Symptoms

The signs and symptoms of parasomnia vary depending on the specific type but generally include:

• Involuntary Movements: Patients may exhibit unusual movements, such as walking, running, or gesturing while asleep.
• Vocalizations: This can include mumbling, shouting, or other sounds made during sleep.
• Confusion upon Awakening: Individuals may experience disorientation or confusion when waking from an episode, particularly in cases of night terrors or sleepwalking.
• Injuries: Patients may sustain injuries due to falls or accidents during episodes of sleepwalking or RBD.
• Sleep Disruption: Frequent episodes can lead to disrupted sleep patterns, resulting in daytime sleepiness and fatigue.

Patient Characteristics

Certain characteristics may predispose individuals to parasomnias:

• Age: Parasomnias are more common in children, particularly sleepwalking and night terrors, but can persist into adulthood or emerge later in life.
• Family History: A familial tendency is often observed, suggesting a genetic component to these disorders.
