A tensilon test, also called an edrophonium test, is a pharmacological test used for the diagnosis of certain neural diseases, especially myasthenia gravis. [1] It is also used to distinguish a myasthenic crisis from a cholinergic crisis in individuals undergoing treatment for myasthenia gravis. The test has fallen out of use due to suboptimal ...
[9] [10] Babies of mothers with myasthenia may have symptoms during their first few months of life, known as neonatal myasthenia [1] or more specifically transient neonatal myasthenia gravis. [11] Diagnosis can be supported by blood tests for specific antibodies, the edrophonium test, electromyography (EMG), or a nerve conduction study. [1]
Bienfang's test is a clinical test used in the diagnosis of ocular myasthenia gravis. It is used in conjunction with other examination techniques such as Cogan's lid twitch test [1] or enhancement of blepharoptosis from prolonged upward gaze. [2][3] It is a simple, quick, and non-invasive test for ocular myasthenia gravis that can be performed ...
In practice, the edrophonium test has been replaced by testing for autoantibodies, including acetylcholine receptor (AchR) autoantibodies and muscle specific tyrosine kinase (MuSK) autoantibodies. [1] [2] Lambert-Eaton myasthenic syndrome (LEMS), is similar to myasthenia gravis in that it is an autoimmune disease.
Simpson test. Purpose. determine ocular myasthenia gravis. Simpson test is a clinical test used in neurology to determine ocular myasthenia gravis. [1] It was first described by the Scottish neurologist John Alexander Simpson. [2]

Transient neonatal myasthenia gravis is a very rare condition in which a mother with myasthenia gravis passes down her myasthenia gravis-inducing antibodies to her fetus through the placenta, causing the fetus to be born with antibodies that attach to self-antigens at the neuromuscular junction.(reference 12) Most cases of transient neonatal ...
Ocular myasthenia gravis (MG) is a disease of the neuromuscular junction resulting in hallmark variability in muscle weakness and fatigability. MG is an autoimmune disease where anomalous antibodies are produced against the naturally occurring acetylcholine receptors in voluntary muscles. MG may be limited to the muscles of the eye (ocular MG ...
