What is a Miller Fisher syndrome?
Miller Fisher syndrome is a rare, acquired nerve disease that is considered to be a variant of Guillain-Barré syndrome. It is characterized by abnormal muscle coordination, paralysis of the eye muscles, and absence of the tendon reflexes. Like Guillain-Barré syndrome, symptoms may be preceded by a viral illness.
What is the cause of Miller Fisher syndrome?
Miller Fisher Syndrome (MFS) is one of the rare forms of a spectrum of Guillain-Barré syndrome (GBS). It is a neurological condition that causes mild to severe muscle weakness. It is caused by an immune system reaction against certain proteins in our nerves important for movement, sensation, and function.
What are the symptoms of Miller syndrome?
Disease at a Glance Characteristic features include underdeveloped cheek bones, a very small lower jaw, cleft lip and/or palate, abnormalities of the eyes, absent fifth (pinky) fingers and toes, and abnormally formed bones in the forearms and lower legs. The severity of the disorder varies among affected individuals.
Is Miller Fisher a neurological disease?
Miller Fisher syndrome, also known as Fisher’s syndrome, is a neurological disorder characterized by sudden weakness in the face, loss of reflexes, and poor coordination. Miller Fisher syndrome (MFS) is a rare, autoimmune nerve condition.
What can mimic Guillain-Barré syndrome?
Other neurological conditions, which commonly mimic these GBS variants include: brainstem stroke, myasthenia gravis, botulism, infective or inflammatory rhombencephalitis and bacterial, carcinomatous or lymphomatous meningitis.
How is Miller syndrome diagnosed?
Molecular genetic testing can confirm a diagnosis of Miller syndrome. Molecular genetic testing can detect a mutation the DHODH gene, but is available only as a diagnostic service at specialized laboratories.
Is Miller Fisher an autoimmune disease?
MFS is an autoimmune disease in which antibodies against a bacterial or viral infection cross-react with and attack the nerves. The site of attack may be the myelin sheaths, which insulate and protect the nerve fibers (axons), or the axons themselves.
How common is Miller Fisher syndrome?
Miller Fisher syndrome (MFS) is a subgroup of a more common — yet still rare — nerve disorder known as Guillain-Barré syndrome (GBS). While GBS affects just 1 person in 100,000 , MFS is even more uncommon. It makes up just 1 to 5 percent of Guillain-Barré cases in the Western world.
How do you diagnose Miller Fisher syndrome?
There is no definitive diagnostic test. Antibodies against ganglioside GQ1b support the diagnosis but also occur in Bickerstaff brainstem encephalitis. As in GBS, the cerebrospinal fluid often shows a high protein while the cell count remains normal.
Is Miller syndrome genetic?
Miller syndrome is inherited in an autosomal recessive pattern. Recessive genetic disorders occur when an individual inherits an abnormal gene from each parent.
Can Covid cause Miller Fisher?
Miller-Fisher syndrome, a rare variant of Guillain-Barré syndrome (GBS), has been reported after COVID-19 infection.
Is Miller Fisher disease curable?
There’s no cure for Miller Fisher syndrome. But treatment can help your symptoms improve faster. People with Miller Fisher syndrome are usually treated in the hospital. This will allow doctors to rule out Guillain-Barré syndrome, which can be fatal.
Who is affected by Miller syndrome?
Description. Miller syndrome is a rare condition that mainly affects the development of the face and limbs. The severity of this disorder varies among affected individuals. Children with Miller syndrome are born with underdeveloped cheek bones (malar hypoplasia) and a very small lower jaw (micrognathia ).

What does Miller Fisher syndrome mean?
Miller Fisher syndrome, also known as Fisher’s syndrome, is a neurological disorder characterized by sudden weakness in the face, loss of reflexes, and poor coordination. Miller Fisher syndrome (MFS) is a rare, autoimmune nerve condition. It is a less-severe form of Guillain-Barré syndrome.
What is Miller Fisher syndrome (MFS)?
– weak eye muscles, with double or blurred vision, and often drooping eyelids with facial weakness; – poor balance and coordination with sloppy or clumsy walking; and – on physical examination, loss of deep tendon reflexes, such as the knee and ankle jerk.
What is the history of Miller Fisher syndrome?
The focus of our review will be the Miller Fisher syndrome (MFS), a rare variant of GBS. James Collier first discovered the variant in 1932 and described it as a triad of symptoms including ophthalmoplegia, ataxia, and areflexia. Miller Fisher later characterized it in 1956, classifying it as a unique entity within the GBS spectrum.
