Myasthenia gravis: muscular chronic fatigue (P1)
Diagnosis of the disease is primarily clinical; the patient may have diplopia (double vision), ptosis (drooping eyelid), difficulty chewing, swallowing , or speaking (nasal or nasal voice); difficulty performing physical activities due to fatigue.
Dr. Bernardo Diaz Cacho Myasthenia gravis is an autoimmune disease, the name comes from the Greek words myos, meaning muscle, and asthenia, which is weakness, so you can start with chronic fatigue. This condition should be treated by a neurologist .
Previously it was considered very serious; this disease is acquired, not inherited, and is characterized by significant weakness, which changes during the day, worse at night and in the mornings patients tend to be much better. The causes of myasthenia gravis are not known for sure. It is thought that there are some factors exposure and some genetic predisposition, but has not found the exact etiology of this disease. It is a disease that is not contagious, that is not inherited and is extremely rare; if not diagnosed early it can have serious complications in the patient's life.
Diagnosis and treatment for myasthenia
Diagnosis of the disease is primarily clinical; the patient may have diplopia (double vision), ptosis (drooping eyelid), difficulty chewing, swallowing, or speaking (nasal or nasal voice); difficulty performing physical activities due to fatigue. You have to confirm the diagnosis with laboratory tests and advanced neurophysiology studies, one of these studies neurophysiology (Jolly or repetitive test electrostimulation, single fiber electromyography -EMG-) is to provide a kind of "touches" in some parts the body to see if the muscle exposed to various stimuli is weakened, and the blood test most commonly used is the elevation of acetylcholine antireceptor antibodies.
