Orphanet Journal of Rare Diseases | A Qualitative Study on the Caregiving Burden of GM1/GM2 Gangliosidoses

Recommend:

This study, through qualitative analysis, systematically explores from the caregiver's perspective the long-term impact of GM1 and GM2 gangliosidoses on patient families for the first time, revealing the multidimensional caregiving burden and its broad effects on quality of life.

 

Literature Overview

This article, titled 'The Burden of Caring for Individuals with GM1 and GM2 Gangliosidoses in the United States: A Qualitative Study', published in the Orphanet Journal of Rare Diseases, reviews and summarizes the responsibilities, challenges, and impacts—psychological, physiological, social, and economic—faced by 29 caregivers while caring for individuals with GM1 or GM2 gangliosidoses. The article emphasizes the central role of caregivers in patients' lives and calls on the medical system, policymakers, and the public to improve the current support system.

Background Knowledge

GM1 and GM2 gangliosidoses are a group of rare autosomal recessive genetic disorders, including Tay–Sachs disease and Sandhoff disease. The primary pathogenic mechanism involves the deficiency of specific enzymes leading to the accumulation of gangliosides in lysosomes, which subsequently causes progressive neurodegenerative lesions. These diseases are classified into infantile, juvenile, and adult forms based on age of onset and severity, with clinical manifestations such as motor function regression, speech impairments, swallowing difficulties, ataxia, and dystonia. Currently, there are no disease-modifying therapies, and treatment remains primarily symptomatic and supportive. Caregivers play a crucial role in disease management, yet their caregiving burden has long been underestimated. This study is the first to systematically evaluate caregiver responsibilities and impacts across multiple dimensions, highlighting key issues such as lack of professional caregiving support, uneven distribution of medical resources, and psychological stress. Conducting this study is significant for improving the quality of life for patients and families, refining caregiving systems, and promoting policy reforms.

Research Methods and Procedures

This study employed a cross-sectional, non-interventional qualitative approach, recruiting 29 caregivers in the United States, including family members caring for children (6–11 years), adolescents (12–17 years), and adults (≥18 years) with GM1 or GM2 gangliosidoses. Through 90-minute focus group discussions conducted both in-person and online, researchers explored caregivers’ responsibilities and challenges in daily care, symptom management, and maintaining quality of life, as well as the impacts on psychological, physiological, social, and economic aspects. The interview content was analyzed using MAXQDA software with both inductive and deductive coding methods to construct a conceptual model of caregiving burden.

Key Findings and Perspectives

• Regardless of patient age or disease type, caregivers universally face constant, round-the-clock caregiving pressure with minimal external support
• Over 80% of caregivers report persistent psychological burden, nearly 60% face financial difficulties, and more than half experience physical strain and social restrictions
• Patients often require assistance with daily activities such as eating, dressing, mobility, and bathing, and these needs intensify as the disease progresses
• While caregivers rely on patient advocacy organizations like NTSAD for resources, they generally perceive public support systems as insufficient
• Despite the heavy caregiving burden, caregivers also report positive experiences, including enhanced family cohesion, personal growth, community support, and shifts in life perspectives

Significance and Future Directions

This study provides valuable insights for healthcare professionals, policymakers, and patient support organizations, emphasizing the critical importance of caregiving support systems in rare disease management. Further development of resources tailored for caregivers, such as psychological support, financial aid, and disease-modifying therapies, is needed. The findings also lay a theoretical foundation for improving patient quality of life and optimizing family health policies.

Conclusion

The study systematically reveals the multidimensional burden experienced by caregivers of individuals with GM1 and GM2 gangliosidoses, encompassing psychological, physiological, social, and economic aspects. It emphasizes the continuous and pervasive nature of caregiving responsibilities and highlights the central role of caregivers in disease management. Significant gaps remain in the current healthcare system regarding early disease recognition, resource allocation, and caregiving support, underscoring the urgent need to enhance awareness of these rare diseases among both the public and the medical community. Furthermore, caregivers express a strong demand for disease-modifying therapies and broader social support systems, which provide important directions for future research and policy development. The study also indicates that despite the challenges, caregivers experience positive outcomes in emotional connection, family unity, and shifts in life perspectives, suggesting that psychological resilience and family dynamics may play a moderating role in long-term caregiving. Future efforts should focus on interventions to support caregiver mental health and optimize caregiving systems.
