Abstract
Neuromuscular disorders (NMDs) encompass a highly diverse group of conditions that affect the skeletal muscles, peripheral nervous system, or motor endplate. Depending on the underlying disease, common characteristics include progressive muscle weakness and sensory disturbances, both of which can contribute to sleep disruption. Disorders of sleep are extremely frequent in NMDs and substantially co-determine overall morbidity, quality of life, and survival. As many NMDs currently lack a cure, supportive therapy is mandatory and includes appropriate management of sleep-related symptoms. Specific sleep disorders that may arise in NMDs include insomnia due to pain or leg muscle cramps, restless legs syndrome, and sleep-disordered breathing, notably obstructive sleep apnea and hypoventilation. This review article aims to comprehensively outline the clinical spectrum of sleep disorders and sleep properties associated with NMDs.
