Myasthenia Gravis Foundation of America

For a World without Myasthenia Gravis

Myasthenia gravis, also known simply as MG, is a rare neuromuscular disorder. Today the MGFA has grown into the largest, leading patient advocacy organization solely dedicated to finding a cure for MG while improving the lives of people living with the disease. More than 70,000 are diagnosed and living with MG in the United States alone. Those with myasthenia suffer with profound, debilitating physical symptoms such as extreme fatigue and muscle weakness that impact a person’s ability to see, swallow, smile, walk or breathe.
