Che malattia è la Miastenia Gravis?
La miastenia gravis (MG) è una malattia rara causata da una risposta immunitaria anomala (autoimmune) che compromette la comunicazione fra i nervi e i muscoli, provocando affaticamento e debolezza muscolare (il termine miastenia, di origine greca, significa muscolo senza forza).
Cosa provoca la miastenia oculare?
Malattia di tipo autoimmune, la miastenia oculare insorge perché alcuni autoanticorpi inibiscono il meccanismo nervoso che permmette la contrazione dei muscoli appartenenti al compartimento oculare. I tipici sintomi della miastenia oculare sono due: diplopia (o visione doppia) e ptosi (o palpebra cadente).
What is the life expectancy of someone with myasthenia gravis?
- In moderate cases, people can take medicines and continue to do their routine work and lead a normal life. The life expectancy of people with myasthenia gravis is almost near to normal lifespan of people, except in very rare cases.
What is the most common cause of death from myasthenia gravis?
- The most common causes of death among patients with myasthenia gravis are respiratory failure (when the muscles that control breathing are too weak to function properly), aspiration (the inhalation of food or drink into the lungs) due to an absent or weakened gag reflex, pneumonia, and falls.
Can myasthenia gravis go away on its own?
- Myasthenia gravis is a chronic (long-lasting) disease that usually worsens slowly over time. Although symptoms may fluctuate in severity over the years, the disease rarely goes away on its own. It is likely to return even after periods when the disease has not been active.

- Antibiotics - Macrolides,fluoroquinolones,aminoglycosides,tetracycline,and chloroquine
- Antidysrhythmic agents - Beta blockers,calcium channel blockers,quinidine,lidocaine,procainamide,and trimethaphan
