Myasthenia gravis is an autoimmune and chronic neuromuscular disease characterized by varying degrees of weakness of the skeletal (volunteer) muscles of the body.
The name comes from Latin and Greek, and literally means "severe muscle weakness," as collected by Wikipedia.
Myasthenia gravis is a rare or low-prevalence disease, with less than one person in two thousand.
It is estimated that affects 9,000 people in Spain.
It starts with an insidious picture of loss of strength, which quickly recovers with rest but reappears when the exercise resumes.
The main feature of myasthenia gravis is a muscle weakness that increases during periods of activity and decreases after periods of rest.
Certain muscles - such as those controlling eye and eyelid movement, facial expression, chewing, speech and swallowing - are often affected by this disorder.
Muscles that control breathing and movements of the neck and limbs may also be affected, but, fortunately, later.
Most people affected by myasthenia gravis develop "myasthenia ocular" in the early stage of the disease, which causes the muscles that control the movement of the eye and eyelids to be affected, causing a drooping eyelid, blurred vision, or double vision.
