Myasthenia gravis is caused by an abnormal immune reaction (antibody-mediated autoimmune response) in which the body’s immune defenses (i.e., antibodies) inappropriately attack certain proteins in muscles that receive nerve impulses.
What is the main cause of myasthenia gravis?
Myasthenia gravis is caused by a problem with the signals sent between the nerves and the muscles. It’s an autoimmune condition, which means it’s the result of the immune system (the body’s natural defence against infection) mistakenly attacking a healthy part of the body.
What is the life expectancy of someone with myasthenia gravis?
Myasthenia gravis can range from mild to severe. In some cases, symptoms are so minimal that no treatment is necessary. Even in moderately severe cases, with treatment, most people can continue to work and live independently. Life expectancy is normal except in rare cases.
How do you develop myasthenia gravis?
Myasthenia gravis is not inherited and it is not contagious. It generally develops later in life when antibodies in the body attack normal receptors on muscle. This blocks a chemical needed to stimulate muscle contraction.Does myasthenia gravis get worse with age?
We have defined myasthenia gravis (MG) in the elderly as onset after the age of 50 years. MG is diagnosed more often today than previously. The increase is mainly found in patients over the age of 50 years. Neurologists therefore see more old patients with MG now than before.

Does myasthenia gravis affect the lungs?
Myasthenia gravis can affect the respiratory system, causing respiratory muscle weakness, an abnormal breathing pattern, and blunted ventilatory responses. Specific treatment can reverse most of these effects and prevent the development of respiratory failure.
Why is myasthenia gravis called the snowflake disease?
MG is often called the “snowflake disease” because it differs so much from person to person. The degree of muscle weakness and the muscles that are affected vary greatly from patient to patient and from time to time.

This condition leads to weakness in the skeletal muscles. Multiple sclerosis (MS) is a chronic neurological condition that’s characterized by progressive nerve damage.

Beware: there are other diseases that mimic myasthenia gravis. A number of disorders may mimic MG, including generalized fatigue, amyotrophic lateral sclerosis (ALS), Lambert-Eaton myasthenic syndrome, botulism, penicillamine-induced myasthenia, and congenital myasthenic syndromes.
