Sleep/Wakefulness Disorders ( 40 Questions)
A client is seeking information about a sleep disorder involving abnormal movements of the limbs or body during sleep. Which of the following conditions is characterized by repetitive or stereotyped movements during sleep or while falling asleep?
Hypersomnolence refers to excessive daytime sleepiness and an increased need for sleep. It is not characterized by abnormal movements of the limbs or body during sleep. Hypersomnolence can be a symptom of various sleep disorders but is not directly related to the condition described.
Periodic limb movement disorder (PLMD) involves repetitive and involuntary movements of the legs and sometimes the arms during sleep. These movements are distinct from the abnormal movements described in the question. PLMD can cause sleep disturbances and daytime fatigue but is not the disorder characterized by stereotyped movements during sleep.
Sleep-related rhythmic movement disorder (SRMD) is characterized by repetitive or stereotyped movements during sleep or while falling asleep. These movements can include head banging, body rocking, or rolling. SRMD is often seen in children and tends to decrease with age. It is a parasomnia, which is a category of sleep disorders involving unusual behaviors during sleep.
Circadian rhythm sleep-wake disorder involves disruptions in the sleep-wake cycle due to misalignments between a person's internal body clock and external cues like light and darkness. It is not characterized by abnormal movements of the limbs or body during sleep. Circadian rhythm sleep-wake disorder can lead to difficulties falling asleep or staying awake at appropriate times but is distinct from the disorder described.
