This systematic literature review investigated caregiver burden in Duchenne muscular dystrophy (DMD). A total of 21 articles were included for data synthesis. Results encompassing more than 15 aspects of caregiver burden, investigated through surveys and/or interviews across 15 countries, were identified in the literature. Caregiving in DMD was frequently associated with impaired health-related quality of life, poor sleep quality, reduced family function, depression, pain, stress, sexual dysfunction, and/or lower self-esteem, as well as a considerable impact on work life and productivity. Providing informal care to a patient with DMD can be associated with a substantial burden. Yet, more research is needed to better understand the clinical implications of caregiving in DMD and the relationship between caregiver burden and the progression of the disease.
