Imagine a condition that leads to symptoms like slurred speech and weakened muscles, double vision, with symptoms only worsening with an increase in activity. A condition like this is called myasthenia gravis, and it is believed to affect thousands of Americans.
This is an autoimmune neuromuscular disorder that mainly affects the voluntary muscles of the body. Persons who suffer from myasthenia gravis suffer from a number of common symptoms that include drooping eyelids, slurred speech, double vision, difficulty in swallowing, difficulty in chewing, muscular weakness, weakness in the arms and legs, chronic muscular fatigue, inability to make facial expressions, problems in talking and even respiratory difficulties.
With a combination of these symptoms, it is not so surprising that a person who suffers from myasthenia gravis quickly finds that his ability to work and earn an income is dramatically reduced.
