What are the symptoms of parasomnias?

Introduction

Parasomnias are a group of sleep disorders characterized by abnormal behaviors, emotions, perceptions, and dreams that occur while falling asleep, during sleep, or during arousal from sleep. These disorders can be disruptive and sometimes dangerous, affecting both the individual and their bed partners.

Key Insights

Common Symptoms Across Parasomnias:
- Motor Behaviors: Abnormal motor activities such as sleepwalking, sleep talking, and dream enactment are common .
- Sensory Experiences: These include perceptions, dreamlike hallucinatory experiences, and autonomic symptoms .
- Emotional Distress: Nightmares and sleep terrors are frequent, causing significant emotional distress .
Specific Symptoms by Type:
- NREM-Related Parasomnias: Confusional arousals, sleepwalking, and sleep terrors, often involving complex motor behaviors and confusion upon waking .
- REM-Related Parasomnias: REM sleep behavior disorder (RBD) involves dream enactment and can be associated with neurodegenerative diseases .
- Sleep-Related Eating and Groaning: These behaviors occur during sleep and can be disruptive .
Associated Factors:
- Age: Parasomnias are more common in children and tend to decrease with age, although some, like RBD, are more prevalent in older adults .
- Comorbid Conditions: Conditions such as ADHD, autism spectrum disorders, and neurodegenerative diseases can be associated with parasomnias.
- Emotional and Psychological Factors: Depressive mood and stress can exacerbate symptoms like confusional arousals and nightmares .

Conclusion

Parasomnias encompass a range of abnormal behaviors and experiences during sleep, including motor activities, sensory experiences, and emotional distress. These symptoms vary depending on whether the parasomnia is related to NREM or REM sleep. While more common in children, certain parasomnias like RBD are prevalent in older adults and can be linked to neurodegenerative diseases. Emotional and psychological factors, as well as comorbid conditions, can influence the occurrence and severity of parasomnias.
