Myasthenia gravis is a chronic and debilitating autoimmune disorder that affects the neuromuscular junction. It is characterized by muscle weakness and fatigue, especially in the face, neck, and limbs. There are several synonyms for myasthenia gravis, including autoimmune myasthenia, myasthenic syndrome, and neuromuscular junction disorder. Other terms that may be used to describe the condition include muscular dystrophy, muscular weakness syndrome, and neurogenic muscle weakness. Regardless of the terminology used, myasthenia gravis remains a challenging condition to diagnose and treat, and patients often require extensive medical management and ongoing supportive care to maintain their quality of life.
