Abstract: Huntington’s disease (HD) is a rare neurodegenerative disorder with a distinct phenotype, including involuntary movements, cognitive decline, and behavioral disturbances. Sleep disorder include insomnia, increased sleep onset latency, decrease in total sleep time with frequent nocturnal awakenings and excessive daytime sleepiness. Increased sleep motor activities and abnormal nocturnal agitation have been increasingly recognized as an important component affecting negatively the sleep quality. Here, we report a case of an intensification of diurnal choreic movement during the night, notably during REM-sleep in a patient with manifest HD. This case highlights the diversity of nocturnal sleep motor disorders encountered in HD.
