The Lowdown on Myasthenia Gravis

 

What is Myasthenia Gravis (MG)?

Myasthenia Gravis is a chronic autoimmune neuromuscular disease that causes weakness in skeletal muscles. The name translates from Latin and Greek origins to “grave, or serious, muscle weakness”. This disease targets muscles that are responsible for breathing and moving body parts, like arms and legs, and is worse after active periods but improves with rest. Often, muscles that control talking, chewing, swallowing, facial expressions, the eyes, breathing, limb movement, and the neck are affected.

Over half of MG cases, eye problems were the first sign. These include ptosis, which is the drooping of one or both eyelids, and diplopia, double vision that improves if one eye is shut. Throat and face muscle symptoms are the first sign in about 15% of those who develop myasthenia gravis. These are the most common symptoms seen in myasthenia gravis patients.

Other symptoms include weakness of the neck, arms, and legs. These don’t usually present themselves without the above symptoms. Legs are less often affected than arms but may cause patients to waddle. More seriously, breathing can be affected and can be a critical issue. Continue reading “The Lowdown on Myasthenia Gravis”
