Answer: Myasthenia gravis
Explanation:
Myasthenia gravis is a weakness and rapid fatigue of muscles under voluntary control. It is caused by a breakdown in communication between muscles and nerves. As the affected muscle is being used, the weakness worsens. Since it improves with rest, the weakness comes and goes, but it progresses over time and reaches its worst within a couple of years after it starts.
It affects any of the muscle that is controlled voluntarily. It is caused by antibodies that block the protein that forms the nerve-muscular junction. Treatment depends on age, severity of the disease and the growth rate of the disease. Medications, intravenous therapy, surgery are treatment methods for the disease.
