Myasthenia gravis is a condition that impairs the muscles of the body. It is a neuromuscular condition that is characterized by muscular fatigue and weakness. Initial symptoms of myasthenia gravis may include vision blurring or double vision and slurred or unclear speech. The person may experience trouble swallowing and other signs of fatigue. These symptoms are often mistaken for other conditions, which often leads to a delayed diagnosis.
Since this is a progressive disorder, symptoms like fatigue and muscular weakness can be expected to worsen over time. The person may suffer from drooping eyelids, trouble speaking, eating or chewing food, and weakness in the arms and legs. In its most severe form, the condition can trigger a myasthenia gravis crisis in which the muscles responsible for respiration become weak and unable to function. In such cases, artificial respiration may have to be used.
If you find yourself suffering from sudden and unexplained weakness in the extremities, difficulty in holding your head up, or slurred speech, contact a doctor immediately. Diagnostic tests for myasthenia gravis can include blood analysis, edrophonium tests, CT scans, and MRI scans.
