Myasthenia Gravis Association

Myasthenia Gravis (MG) is a disease which appears to the sufferer to weaken the muscles.
It is a disorder of the junction between the nerve and the muscle, caused by the body's immune system attacking a vital part of this junction - this impairs the ability of the nerve to cause muscle contraction, and hence produces the apparent weakness.
The cause of this auto-immune reaction is not yet known. The MGA are the only charity in the country dedicated to the Research Care and Education into Myassthenia Gravi
