Myasthenia gravis is a disease of the department of neurology and its incidence is not low, it is also relatively common clinically. The treatment of myasthenia gravis mainly includes the following points: First, if patients with myasthenia gravis also have a thymoma, it is recommended to surgically remove the thymoma as soon as possible, which can significantly alleviate the symptoms of myasthenia gravis and reduce the amount of medication needed. Second, provide patients with some medication, mainly some drugs that suppress the immune response, including some corticosteroids. The use of corticosteroids is relatively complex, and must be gradually increased or decreased under the advice of a doctor. Do not stop taking them on your own. There are also some drugs that are cholinesterase inhibitors, which can increase the content of acetylcholine in the synaptic gap, alleviating the patient's symptoms. In addition, research has confirmed that some new immunosuppressive agents can also be used in the treatment of myasthenia gravis. In summary, the treatment of myasthenia gravis is a comprehensive subject and must be tailored according to the patient's condition.

How is myasthenia gravis diagnosed?

Myasthenia gravis is essentially an immunoreactive disease in neurology, primarily caused by immune dysfunction in the body, leading to the production of autoantibodies. These antibodies attack the acetylcholine receptors on the postsynaptic membrane, resulting in corresponding clinical symptoms such as ptosis, diplopia, and general fatigue. The examination of myasthenia gravis mainly includes the following aspects: first, the completion of the Tensilon test, and if the test is positive, myasthenia gravis should be considered; second, the examination should include repetitive nerve stimulation electromyography, and if there is a significant decrement in wave amplitude, this disease should be considered; third, relevant blood tests should be conducted, mainly to check for acetylcholine receptor antibodies, as positive results for these antibodies are important in supporting this diagnosis.

Myasthenia gravis should not use what medicine?

Myasthenia gravis is a neuromuscular junction disease in neurology, primarily due to some synaptic dysfunction, leading to pathological fatigue and general weakness in patients. Patients with myasthenia gravis often experience exacerbation of the disease due to fatigue or infection, and certain medications can severely affect synaptic function, worsening the condition, and are therefore not to be used. The medications to avoid mainly include the following types: The first type is aminoglycoside antibiotics, which can exacerbate the transmission at the neuromuscular junction. Second, quinolone antibiotics should also be avoided as much as possible. Third, some antiarrhythmic drugs can also decrease the excitability of the fascia and are not recommended. Additionally, some drugs like morphine, benzodiazepines, and receptor blockers should also be contraindicated or used with caution.

What should people with myasthenia gravis pay attention to in their daily lives?

Patients with myasthenia gravis should be careful to continue taking their medications after being discharged from the hospital and must not change the dosage or administration of their medication on their own. It is important to avoid overexertion and emotional stimuli in daily life. One should ensure to get enough rest, maintain adequate sleep, and consume fresh vegetables and fruits. Avoid spicy, stimulating, and excitatory foods. Do not be overly sad or experience excessive emotional fluctuations. Pay attention to the risk of catching a cold and upper respiratory infections. Take precautions against exposure to cold and prevent infections. Balance work and rest, maintain regular life patterns, keep in good spirits, ensure adequate sleep, and avoid excessive emotional disturbances and stimuli.

Myasthenia Gravis should be seen by which department?

Myasthenia gravis is considered a neurological disease, so if myasthenia gravis is suspected, it is advisable to consult a neurologist. Neurologists are quite familiar with myasthenia gravis, especially those who specialize in its research. They are particularly knowledgeable about diagnosing and treating this disease. Myasthenia gravis is an autoimmune disease of the nervous system that primarily affects the neuromuscular junction, causing muscle weakness in the body. The symptoms typically worsen towards the evening and include pathological fatigue. Muscle weakness usually improves after rest. Clinical manifestations also include ptosis, double vision, difficulty swallowing, and coughing while drinking. Neurologists may prescribe various diagnostic tests such as electromyography, chest CT scans, and tests for acetylcholine receptor antibodies.

Types of myasthenia gravis crisis

Myasthenic crises are categorized into three types, all resulting from worsening conditions or improper treatment, leading to respiratory muscle weakness or paralysis and subsequent difficulty in breathing. The first type occurs due to various triggers or reduction in medication, or after the application of acetylcholinesterase inhibitors which temporarily alleviate the crisis, known as the cholinergic crisis. The second type is a result of excessive use of acetylcholinesterase inhibitors during a cholinergic crisis. Beyond respiratory difficulties, symptoms may also include signs of toxicity such as vomiting, abdominal pain, diarrhea, pupil constriction, excessive sweating, drooling, increased tracheal secretions, and potential muscle tremors, spasms, as well as anxiety, insomnia, confusion, seizures, and coma. The third type is the paradoxical crisis, where neither ceasing nor increasing medication doses alleviates the symptoms, typically occurring after long-term, high-dose medication use.
