Background:
Recent medical advances have enabled the control of neurological symptoms and increased survival of patients with myasthenia gravis (MG). However, MG has many veiled consequences that may be underestimated by neurologists. Our aim was to clarify the social, professional, and neuropsychiatric issues of MG patients.
Methods:
We carried out a cross-sectional cohort study with MG patients from a university-affiliated referral hospital. We registered clinical and sociodemographic data, and patients were classified according the MGFA classification. Clinical severity was assessed with Myasthenia Gravis Composite (MGC) scale. Trained and blind investigators analyzed social and professional outcomes. Neuropsychiatric symptoms were evaluated with the Hospital Anxiety and Depression Scale (HADS) and the social support with the Multidimensional Scale of Perceived Social Support (MSPSS).
Results:
We enrolled 49 patients with MG. The mean age was 45.3 ± 18.1 years and 39 (79.6%) were women. There were 19 (38.8%) patients who become unemployed, 23 (46.9%) who had to retire prematurely, 31 (63.3%) that reported a significant reduction in work performance, and 23 (46.9%) who had a reduction in monthly income after the diagnosis of MG. Only 16 (32.6%) received any financial support and 24 (48.9%) patients had the perception of receiving a satisfactory social support. The practice of physical activity is a habit in only 10 patients (20.4%). Neuropsychiatric symptoms were present in 26 (53.1%) patients.
Conclusion:
Patients with MG are vulnerable to social, professional, and mental disadvantages. Therapeutic success in MG goes beyond symptom relief and inevitably depends on a personalized approach to the patient.

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
Chemical Synapses
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...
