option b.
Step-by-step explanation:
Sleep-Wake Disorders in DSM-5
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) categorizes various sleep-related disorders under the Sleep-Wake Disorders section. Restless Legs Syndrome, Hypersomnolence Disorder, and Narcolepsy are all indeed considered Sleep-Wake Disorders. However, Trichotillomania is not included in this category as it is characterized by a recurrent compulsion to pull out one's hair, which is more related to Obsessive-Compulsive and Related Disorders than to sleep-specific dysfunctions.
When diagnosing and treating disorders like Restless Legs Syndrome and Narcolepsy, healthcare professionals reference the DSM-5 to determine the right intervention strategies. Restless Legs Syndrome causes uncomfortable sensations in the legs during periods of rest or inactivity, leading to movements that can disturb sleep. On the other hand, Narcolepsy is characterized by an uncontrollable need to sleep and may include symptoms such as cataplexy and vivid hallucinations reminiscent of REM sleep. Both disorders can significantly affect the quality of life of individuals and require proper treatment and management.
