Neuromusclar disorder - myasthenia gravis
Myasthenia gravis is a neuromuscular disorder. Neuromuscular disorders involve the muscles and the nerves that control them.
Myasthenia gravis is a type of autoimmune disorders. An autoimmune disorder occurs when the immune system mistakenly attacks healthy tissue. In people with myasthemia gravis, the body produces antibodies that block the muscle cells from receiving messages (neurotransmitters) from the nerve cell.
The exact cause of myasthenia gravis is unknown. In some cases, it may be associated with tumors of the thymus (an organ of the immune system).
Myasthenia gravis can affect people at any age. It is most common in young women and older men.
