Myasthenia gravis: Symptoms, diagnosis and treatment Myasthenia gravis is a rare and chronic condition causing muscles to tire and get weaker easily. Myasthenia gravis often affects muscles of the eyes and eyelids, the face and those used for chewing and speech. Muscles used for breathing, and those in the neck, arms and legs can also be affected. Myasthenia gravis is an autoimmune disorder where the body's defences wrongly turn on nerves and muscles.

Myasthenia Gravis Myasthenia Gravis. Myasthenia gravis is a condition where muscles become easily tired and weak. It is due to a problem with how the nerves stimulate the muscles to tighten (contract). The muscles around the eyes are commonly affected first. This causes drooping of the eyelid and double vision.

Myasthenia Gravis Myasthenia gravis facts*. *Myasthenia gravis facts medical author: Charles Patrick Davis, MD, PhD. 1  Myasthenia gravis is a chronic autoimmune neuromuscular disease characterized by varying degrees of weakness of the skeletal (voluntary) muscles of the body. The symptoms of myasthenia gravis may include eye muscle weakness, eyelid drooping (ptosis), blurry or double vision (diplopia), unstable gait, a change in facial expression, difficulty in swallowing, shortness of breath, impaired speech, and weakness in the arms, hands, fingers, legs, and neck.

- Myasthenia gravis is a neuromuscular disorder that causes weakness and fatigue in the muscles that control voluntary movement in the body.The weakness is caused by a disruption in the communication between the muscles and the nerves that control them.hile myasthenia gravis can affect any voluntary muscles in the body, most patients will first notice its effects in the muscles that control the movement of the eyes and eyelids. The weakening of these muscles can result in droopy eyelids, double vision and partial paralysis of eye movements.

- Myasthenia gravis (my-us-THEE-nee-uh GRAY-vis) is characterized by weakness and rapid fatigue of any of the muscles under your voluntary control. Myasthenia gravis is caused by a breakdown in the normal communication between nerves and muscles. There is no cure for myasthenia gravis, but treatment can help relieve signs and symptoms, such as weakness of arm or leg muscles, double vision, drooping eyelids, and difficulties with speech, chewing, swallowing and breathing.

Muscle weakness Muscle weakness. Not to be confused with muscle fatigue. Muscle weakness or myasthenia (my- from Greek μυο meaning muscle + -asthenia ἀσθένεια meaning weakness) is a lack of muscle strength. The causes are many and can be divided into conditions that have either true or perceived muscle weakness.

- Myasthenia gravis. Myasthenia gravis (MG) is a condition where the body's own defense, the immune system, attacks the body. In MG, the intersection between nerve and muscle is the target, causing a blockade of signals that would otherwise command the muscle to go into action.
