What can be done to prevent the disease?
There are no known ways to prevent myasthenia gravis.
What are the long-term effects of the disease?
The symptoms of myasthenia gravis often worsen over the first 5 to
7 years of the disease. After this time, the disease is usually not
progressive. Symptoms may worsen and improve as muscles are used and then
rested throughout the day.
In some cases, myasthenia
gravis may get better or worse over time. About 20% of the people with
myasthenia gravis have a natural remission, or improvement, of the disease that
lasts a year or more. With good treatment, people with myasthenia gravis have
a normal life expectancy.
What are the risks to others?
Myasthenia gravis is not contagious and poses no risk to others.
