Myasthenia gravis MG is a disorder of neuromuscular transmission, resulting from binding of autoantibodies to components of the neuromuscular junction, most commonly the acetylcholine receptor [ 1 ]. This leads to muscular weakness with easy 'fatiguability', which is worse on exercise and improves with rest. Almost all MG patients will have ocular manifestations at some point during the course of their disease. The clinical presentation varies from mild weakness of limited muscle groups class I, or ocular, MG to severe weakness of multiple muscle groups class V, or severe generalised, MG.

If patients have restricted ocular disease for two years without developing generalised MG, they are not likely to develop it later. When weakness is limited to the extrinsic ocular muscles and levator palpebrae superioris, the disease is called ocular myasthenia [ 9 ]. Weakness of the muscles of ventilation can cause acute respiratory failure. This is an acute neurological emergency that requires ventilation. Weak pharyngeal muscles can also lead to compromise of the airway. Myasthenic crisis MC is a complication of MG characterised by worsening muscle weakness resulting in respiratory failure that requires intubation and mechanical ventilation. Most patients have a predisposing factor that triggers the crisis, often a respiratory tract infection.

It may present as a postsurgical patient, in whom exacerbation of muscle weakness from MG causes a delay in extubation. Immunoglobulins, plasma exchange and steroids are the cornerstones of immunotherapy. It can be extremely difficult to distinguish between worsening of myasthenia MC or excessive anticholinergic medication cholinergic crisis when a patient with known MG presents with rapidly increasing muscular weakness, with or without respiratory difficulty. Features suggestive of a cholinergic crisis too much medication include muscle fasciculation, pallor, sweating, hypersalivation and small pupils. If in doubt, perform an edrophonium test. Improvement suggests too little medication, ie MC; however, aggravation suggests too much medication.

Be prepared to stop all medication, ventilate and possibly arrange a plasmapheresis. This test should only be performed with the necessary skills and equipment ready for intubation and ventilation. There are a number of drugs that can aggravate the condition. They should be used with caution if essential but are best avoided:. Myasthenic syndromes: diseases of neuromuscular junction result from immune, toxic, genetic pathologies, including [ 13 ] :. The diagnosis is based on clinical features, the benefit of cholinesterase inhibitors, the detection of specific autoantibodies anti-AChR, anti-MuSK or anti-LRP4 , and electrophysiological tests [ 14 ].

If the diagnosis of MG is suspected, refer the patient to a neurology unit for further investigations. In patients with ptosis, the ice test is a simple first-line test while waiting for other investigations. This distinguishes MG from other causes of ptosis. Crushed ice in a latex glove is applied to the eye for three minutes. What causes myasthenia gravis? Who gets myasthenia gravis? How is myasthenia gravis diagnosed? How is myasthenia gravis treated? What is the prognosis? What research is being done? Where can I get more information? Myasthenia gravis is a chronic autoimmune, neuromuscular disease that causes weakness in the skeletal muscles that worsens after periods of activity and improves after periods of rest.

These muscles are responsible for functions involving breathing and moving parts of the body, including the arms and legs. Available treatments can control symptoms and often allow people to have a relatively high quality of life. Most individuals with the condition have a normal life expectancy. The hallmark of myasthenia gravis is muscle weakness that worsens after periods of activity and improves after periods of rest. Certain muscles such as those that control eye and eyelid movement, facial expression, chewing, talking, and swallowing are often but not always involved in the disorder.

The onset of the disorder may be sudden, and symptoms often are not immediately recognized as myasthenia gravis. The degree of muscle weakness involved in myasthenia gravis varies greatly among individuals. Sometimes the severe weakness of myasthenia gravis may cause respiratory failure, which requires immediate emergency medical care. A myasthenic crisis is a medical emergency that occurs when the muscles that control breathing weaken to the point where individuals require a ventilator to help them breathe. It may be triggered by infection, stress, surgery, or an adverse reaction to medication. Approximately 15 to 20 percent of people with myasthenia gravis experience at least one myasthenic crisis.

However, up to one-half of people may have no obvious cause for their myasthenic crisis. Certain medications have been shown to cause myasthenia gravis. However, sometimes these medications may still be used if it is more important to treat an underlying condition. Myasthenia gravis is an autoimmune disease, which means the immune system—which normally protects the body from foreign organisms—mistakenly attacks itself. Myasthenia gravis is caused by an error in the transmission of nerve impulses to muscles.
