Myasthenia Gravis

There are many neurological and digestive diseases. They cause massive damage and harm to the human body. Many of these diseases are really serious and cause death. I chose a very rare neurological disease known as Myasthenia Gravis. It is more common in highly advanced regions like America and Europe, because newborns with this disease require advanced resuscitation that is not available in third world countries.

Myasthenia Gravis is caused by a defect of neuromuscular transmissions that affects muscle receptors. This defect results in the constant attack of the muscle receptors by antibodies. The antibodies never usually assault their own body parts but something causes them to attack the muscle receptors. It has not been determined yet why and for what reason the antibodies do this strange thing. All that is known that the antibodies disrupt the connection between nerves and muscle receptors causing muscle weakness. This damage induces weakness in most of the muscles of the body. Thus making it hard to move and breath.

How this disease begins is not known yet. It is thought that maybe a persistent viral infection is possible. The Thymus gland is almost always abnormal. This is leading researchers to believe that the Thymus gland is involved. Also there are a number of familial cases of Myasthenia Gravis. This suggests that this disease could be passed on by genetic predisposition.

Typical Myasthenia Gravis may begin at any time. Though it is most common between the ages of 10 and 65. Usually the people with this disease do not live a very long and enjoyable life. This is due to the fact that the antibodies attack the lung muscles and eventually the lungs will collapse leading to death of the patient. Some of the victims of Myasthenia Gravis have to spend the substantial part of their life wheelchair bound. Muscles of their legs do not get proper message from nervous system because muscle receptors are destroyed.

When a normal person not suffering from Myasthenia Gravis steps forward with his leg he does not think about the process of moving his leg. A person suffering from Myasthenia Gravis has major problems when wanting to go somewhere. The person must put all his effort in getting the message through to his leg to move it. The antibodies destroy 80% of the muscle receptors. Then they go after the nerves that communicate to the muscle receptors to finish of any possibility of movement in a muscle. After these constant attacks on the muscle receptors, they work at 20% of what is normal.
