Sleep-related movement disorders and disturbances of motor control cover a broad range of conditions with a negative impact on an individual’s quality of sleep and daily functioning: (1) sleep-related movement disorders (e.g., periodic limb movements in sleep, restless limbs/legs syndrome, sleep-related leg cramps, sleep-related bruxism, sleep-related rhythmic movement disorder); (2) sleep-related disturbances of motor control, including (2a) parasomnias, such as RBD, sleepwalking, sleep-related eating disorder, sleep terror, sleep paralysis, (2b) sleep-related epileptic syndromes, such as nocturnal epilepsy with simple motor manifestations, nocturnal epilepsy with complex motor manifestations (sleep-related hypermotor epilepsy), and (2c) sleep-related dissociative disorders/psychogenic non-epileptic seizures. This chapter is designed to be a resource for clinicians, sleep specialists, and researchers, offering a comprehensive overview on the distinct features and characteristics; epidemiologic aspects; underlying pathophysiologic mechanisms; diagnostic criteria; and available treatment/management options of sleep-related movement disorders and sleep-related disturbances of motor control.
