Myasthenia Gravis Disease
An autoimmune disease, myasthenia gravis is a condition that affects the communication between nerves and muscles. Its main symptom is muscle weakness that increases during activity and improves after rest. Myasthenia gravis may affect any voluntary muscle. However, it most typically affects the muscles that control eye and eyelid movement, facial expression, and swallowing.
Although it most commonly affects women under the age of 40 and men over age 60, myasthenia gravis can occur at any age. Current treatment options for this disease include medications, plasma exchange, and thymectomy, among others.
