Myasthenia gravis, this disease definitely requires registration with the Department of Neurology as it is a relatively common disease in neurology, and doctors in other departments are not particularly familiar with this disease, let alone diagnosis and treatment. Myasthenia gravis is an immune disease of the nervous system, and patients may experience generalized fatigue, which can be alleviated after rest. It is characterized by clinical symptoms that are lighter in the morning and more severe in the evening. Additionally, symptoms such as ptosis, double vision, and even some difficulties in swallowing and unclear speech, known as bulbar paralysis, may occur. This disease requires a thorough chest CT scan, as many patients have an associated thymoma. Furthermore, an electromyography examination is needed to check for antibodies related to myasthenia gravis, which is also important for guiding further treatment.

incidence of myasthenia gravis

Myasthenia gravis is a disease of the neurology department. Its incidence rate is around one in one hundred thousand. The prevalence rate is around fifty per one hundred thousand. In China, the incidence rate in the south is slightly higher than in the north. This is an autoimmune disease of the nervous system. Generally, it is due to the production of some abnormal antibodies. These antibodies cause dysfunction in synaptic transmission at the neuromuscular junction, leading to corresponding clinical manifestations in patients. For example, extreme fatigue after physical activity that can only be alleviated by rest. Patients may also exhibit clinical symptoms such as ptosis, diplopia, and difficulty swallowing, and in severe cases, even respiratory muscle weakness may occur, requiring the use of a ventilator. This disease can occur at any age, affecting children as well as elderly men aged 70 to 80. Therefore, correct understanding of this disease and timely treatment are very important.

Types of Myasthenia Gravis Crisis

Myasthenia gravis is a neurological disease. It is an autoimmune disorder primarily affecting the neuromuscular junction, leading to symptoms such as pathological fatigue, ptosis, and limb weakness. Myasthenia gravis is termed as such due to its severe nature, including crises that can impair respiratory muscles, leading to respiratory paralysis, respiratory failure, and potentially death. There are three main types of myasthenic crises. The first type is myasthenic crisis, primarily caused by insufficient medication; muscular injections can be used for treatment, and if effective, it indicates a myasthenic crisis. The second type is called cholinergic crisis, resulting from an overdose of acetylcholinesterase inhibitors, with symptoms including muscular twitching and pupil constriction. The third type is called refractory crisis, occurring when the body is insensitive to medication treatments. All these crises pose a life-threatening risk to patients and require immediate management, including tracheal intubation and, if necessary, mechanical ventilation.

Myasthenia Gravis Test Items

Myasthenia gravis is a common neurological disease, primarily an autoimmune disorder. It typically results in symptoms that are worse in the evening and fluctuate throughout the day, mainly manifesting as limb weakness, double vision, swallowing difficulties, and speech impairments. In severe cases, it can even affect respiration, leading to weakness of the respiratory muscles and necessitating the assistance of a ventilator. The key examinations for myasthenia gravis include: Firstly, a chest CT scan. Many patients with myasthenia gravis have thymic hyperplasia or thymomas, making this scan crucial. Secondly, repetitive nerve stimulation electromyography. This test can detect amplitude decrement in response to stimulation, which is significant for diagnosing the disease. Thirdly, testing for specific antibodies related to myasthenia gravis, such as acetylcholine receptor antibodies. The presence of these antibodies is very important for diagnosis. Additionally, other tests such as erythrocyte sedimentation rate and thyroid function tests are also conducted.

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.
