Assessing the Burden on Caregivers of MECP2 Duplication Syndrome.

ABSTRACT

BACKGROUND: MECP2 duplication syndrome (MDS) is a rare neurogenetic disorder characterized by severe neurodevelopmental disorder, refractory epilepsy, recurrent infections, and functional gastrointestinal problems. Because of the significant clinical problems and lifelong disability of children with this disorder we hypothesized that the burden on parents/caregivers of these children is significant. However, there are no reports of the impact on caregivers of individuals with MDS. METHODS: We developed and validated a burden scale to investigate the challenges of caregivers of children and adults with MDS and identified factors contributing to the burden on caregivers. We developed a Health Insurance Portability and Accountability Act-compliant patient registry for families with MDS and delivered caregiver burden survey through the registry. RESULTS: Of 237 completed surveys, 101 were eligible for the study. We identified increased levels of self-perceived anxiety, depression, and emotional exhaustion in caregivers that correlated with higher burden scores. Epilepsy was the only clinical feature that caused a higher burden in caregivers of individuals with MDS. In addition, a higher burden was found in Hispanic caregivers. The duration of care negatively correlated with burden score. CONCLUSIONS: This is the first study to investigate the burden on caregivers of individuals with MDS and identify several factors contributing to increased burden. Addressing these concerns has the potential to improve the health of individuals with MDS and contribute to the well-being of their caretakers.
