The diagnostic precision of MG, along with the emergence of novel treatments targeting the autoimmune response, has ushered the field into a new era, moving MG management closer to personalized medicine. However, critical gaps remain, including the absence of approved treatments for seronegative MG, limited attention to Lambert-Eaton myasthenic syndrome and congenital myasthenic syndromes, and the need for more precise biomarkers. Current clinical trials primarily rely on outcomes that measure symptoms and/or muscle weakness/fatigability; however, there is a need for biomarkers that better reflect disease activity, enable early diagnosis in seronegative MG, and identify the underlying antibodies in these patients. Predictive biomarkers are also needed to assess the risk of generalization from ocular MG and the likelihood of relapses. Furthermore, despite their efficacy, novel treatments such as complement and FcRn inhibitors are costly and inaccessible in many countries. Future MG research must, therefore, prioritize socioeconomic considerations alongside therapeutic advancements. Also, a better understanding of the fatigue in MG, with differences in men and women, is essential to better design treatment over time.

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...
