Myasthenia gravis in the elderly

Myasthenia gravis (MG) is an autoimmune disease of neuro-muscular synaptic transmission disorder. The main clinical feature is that the affected striated muscles are prone to fatigue, and symptoms can be relieved after rest or with anticholinase drugs. Myasthenia gravis is a polygenic disease. Currently, anti-acetylcholine receptor (AchR) antibodies and antibody-mediated humoral immunity and T cell-mediated cellular immunity are the main pathogenesis. The thymus is the main factor that activates and maintains the autoimmune response of myasthenia gravis. Genetic and environmental factors are also closely related to the onset of myasthenia gravis.
