Sleep disorder

Answer 1

Sleep disorders are a category of psychological conditions that affect an individual’s ability to sleep well on a regular basis. According to the DSM-IV classification referenced in the provided text, sleep disorders are categorized into primary sleep disorders, which are further divided into two main types:

1. Dyssomnias: These involve difficulties in getting enough sleep, staying asleep, or excessive sleepiness. Common dyssomnias include insomnia, hypersomnia, and narcolepsy.
2. Parasomnias: These are characterized by abnormal behaviors or physiological events occurring during sleep or sleep-wake transitions, such as sleepwalking, night terrors, and nightmares.

These disorders can significantly impair emotional, social, and physical functioning and often require clinical evaluation and treatment.
