Myasthenia Gravis

📖What is Myasthenia Gravis?

Myasthenia gravis is a chronic autoimmune disorder in which the body's immune system mistakenly produces antibodies that block or damage the connection between nerves and muscles, impairing the normal transmission of signals needed for muscle contraction. This disruption at the neuromuscular junction leads to a characteristic pattern of muscle weakness that worsens with repeated use or activity and improves with rest, distinguishing it from many other causes of muscle weakness. The condition most commonly affects muscles controlling eye movement and eyelid position first, though it can progress to involve muscles responsible for facial expression, swallowing, speech, and, in more severe cases, breathing. Myasthenia gravis can affect people of any age but shows a bimodal pattern, more commonly diagnosed in younger women and older men. While there is no cure, a range of treatments can effectively control symptoms for most patients, allowing many to lead active, largely normal lives, though careful management of potential severe flares remains important.
