Myasthenia gravis causes muscle weakness due to the immune systemattacking neurotransmitter receptors on muscle tissue. Since the muscle can’t receive the signal to contract, people with myasthenia become weak. While this neuromuscular junction disorder used to always be disabling and even fatal, now it can usually be managed with various therapies.
There are five general ways of treating myasthenia gravis. Some methods are best used in acute crises in order to keep someone out of an intensive care unit, although this is still sometimes necessary in extreme cases. Others are meant more to avoid such crises happening in the first place — a preventive strategy.
