ABSTRACT

Introduction: Myasthenia gravis (MG) is a chronic autoimmune disorder in which fatigue represents one of the most burdensome symptoms. This multidimensional manifestation extends beyond neuromuscular fatigability and has a substantial impact on daily functioning, mental health, and quality of life. The present study aimed to evaluate the perception of fatigue in patients with MG, with particular emphasis on its interference with everyday activities and the extent to which it is understood by others. Methods: The study included 67 MG patients (61.2% women, mean age 53 years) treated at the Neurology Outpatient Department of the University Clinical Center in Gdańsk. Data were collected using an author-developed survey and standardized instruments: Chalder Fatigue Scale (CFQ), MG-ADL, MG-QoL15, HADS-M, Mini-COPE, and ACDS. Results: More than 70% of patients reported constant or frequent fatigue. Higher fatigue severity was positively associated with functional impairment (MG-ADL) and lower quality of life (MG-QoL15). More than 70% of patients reported constant or frequent fatigue. Higher fatigue severity was moderately associated with greater functional impairment and poorer quality of life. The extent to which fatigue interfered with daily life was associated with higher levels of depressive symptoms, poorer self-rated health, and less favorable disease-related perceptions (acceptance and influence). In contrast, perceiving fatigue as being better understood by others was associated with lower anxiety and depression and more favorable disease-related perceptions (acceptance, control, understanding), while it was not significantly related to fatigue severity, functional status, or quality of life. Conclusions: Fatigue in myasthenia gravis is a prevalent symptom, closely related to functional impairment and reduced quality of life. Different aspects of fatigue perception show distinct psychosocial correlates, highlighting the importance of considering subjective and social dimensions of fatigue alongside its severity. These findings support the relevance of psychosocial factors in the comprehensive care of patients with MG.
