Miller Fisher Syndrome

 Miller Fisher Syndrome



Overview

What is Miller Fisher syndrome?

Miller Fisher syndrome (MFS) is a rare disorder that causes your immune system to attack nerves, usually starting in your face. It can affect the nerves that control your eye muscles, so you may have trouble moving your eyes. MFS also can cause problems with your coordination and reflexes. Symptoms usually follow a viral or bacterial infection.

Who gets Miller Fisher syndrome?

Anyone can get Miller Fisher syndrome, but it’s more common in:

People of Asian descent.

Males. MFS affects males twice as often as females.

Adults over the age of 55.

What’s the difference between Miller Fisher syndrome and Guillain-Barré syndrome?

Miller Fisher syndrome is a form of Guillain-Barré syndrome (GBS). Like MFS, GBS is an autoimmune disease triggered by an infection. But MFS tends to affect your upper body first, whereas GBS typically affects your lower body and then spreads upward. Common symptoms of GBS include back pain, breathing problems and muscle weakness in your feet, legs and hands. GBS is also more common than MFS.

Symptoms

What are the symptoms of Miller Fisher syndrome?

The symptoms of Miller Fisher syndrome tend to come on suddenly and develop over a few days. Symptoms usually start about 10 days after a viral or bacterial infection. Sometimes, your symptoms may not appear for several weeks.

The most common symptoms of MFS include:

Balance problems.

Changes in the way you walk.

Double vision (diplopia) or blurred vision.

Drooping eyelids (ptosis) or facial paralysis (difficultly moving muscles in your face).

Loss of tendon reflexes in your ankle, knee or arm.

Problems with eye movements.

Sloppy or clumsy muscle movements.

You may also develop:

Breathing problems.

Muscle weakness in your arms and legs.

Swallowing problems.

Tongue weakness.

What causes Miller Fisher syndrome?

MFS can develop if your immune system reacts to an infection and mistakenly attacks nerves while it’s trying to fight the infection. Viral and bacterial infections that may trigger MFS include:

Campylobacter infection.

Haemophilus influenzae.

Human immunodeficiency virus (HIV).

Mononucleosis (Epstein-Barr virus).

Zika virus.

Is Miller Fisher Syndrome hereditary?

MFS may be inherited (passed down from parents to children), but it’s rare for two people in the same family to have the disorder.

Diagnosis

How is Miller Fisher syndrome diagnosed?

There isn’t a test that can confirm a diagnosis of MFS. Your healthcare provider will perform a physical exam, evaluate your symptoms and review your medical history. Be sure to tell your provider if you’ve had a viral or bacterial infection in the last several months.

If your provider suspects you have MFS, they may perform the following tests:

Blood tests: Blood tests can detect high levels of certain antibodies in your blood. Antibodies are proteins your immune system produces to fight infections.

Electromyography: An electromyogram is a test that measures how well your muscles are responding to signals from nerves.

Nerve conduction study: This test measures how quickly an electrical signal moves through your nerves.

Spinal tap: During a spinal tap (lumbar puncture), your provider removes a sample from the fluid surrounding your spine and examines the fluid for certain antibodies.

Treatment

How is Miller Fisher syndrome treated?

There isn’t a cure for Miller Fisher Syndrome, but some therapies can stop your immune system from attacking healthy nerves. The most common treatments include:

Intravenous immunoglobulin (IVIG) therapy: IVIG therapy uses purified plasma (the liquid portion of your blood) and healthy antibodies from donors. It can help prevent your immune system from attacking healthy tissue.

Plasma exchange (plasmapheresis): Plasmapheresis is a procedure to filter your blood of plasma that may contain harmful antibodies.

Physical rehabilitation: You may work with a physical therapist or occupational therapist to regain muscle strength, flexibility and coordination. Therapists can help you improve your balance and gait (walking) and show you techniques for performing daily activities.

Charge Syndrome

Overview CHARGE syndrome is a recognizable genetic syndrome with known pattern of features. It is an extremely complex syndrome, involving extensive medical and physical difficulties that differ from child to child. CHARGE syndrome is correlated with genetic mutation to CHD7 and the prevalence of CHARGE syndrome is 1:10,000-1:15,000 live births. Babies with CHARGE syndrome are often born with life-threatening birth defects. They spend many months in the hospital and undergo many surgeries and other treatments. Swallowing and breathing problems make life difficult even when they come home. Most have hearing two little girls sitting on a carpet, one girl has a trach and is biting her finger.loss, vision loss, and balance problems that delay their development and communication. Despite these seemingly insurmountable obstacles, children with CHARGE syndrome often far surpass their medical, physical, educational, and social expectations. One of the hidden features of CHARGE syndrome is the ...

Dehydration Due to Diarrheal Diseases

Overview Dehydration occurs when you use or lose more fluid than you take in, and your body doesn't have enough water and other fluids to carry out its normal functions. If you don't replace lost fluids, you will get dehydrated. Anyone may become dehydrated, but the condition is especially dangerous for young children and older adults. The most common cause of dehydration in young children is severe diarrhea and vomiting. Older adults naturally have a lower volume of water in their bodies, and may have conditions or take medications that increase the risk of dehydration. This means that even minor illnesses, such as infections affecting the lungs or bladder, can result in dehydration in older adults. Dehydration also can occur in any age group if you don't drink enough water during hot weather — especially if you are exercising vigorously. You can usually reverse mild to moderate dehydration by drinking more fluids, but severe dehydration needs immediate medical treatment. ...

Ataxia with Vitamin E Deficiency

Synonyms of Ataxia with Vitamin E Deficiency AVED Familial Isolated Vitamin E Deficiency Isolated Vitamin E Deficiency General Discussion Ataxia with vitamin E deficiency (AVED) is a rare inherited neurodegenerative disorder characterized by impaired ability to coordinate voluntary movements (ataxia) and disease of the peripheral nervous system (peripheral neuropathy). AVED is a progressive disorder that can affect many different systems of the body (multisystem disorder). Specific symptoms vary from case to case. In addition to neurological symptoms, affected individuals may experience eye abnormalities, disorders affecting the heart muscles (cardiomyopathy), and abnormal curvature of the spine (scoliosis). AVED is extremely similar to a more common disorder known as Friedreich’s ataxia. AVED is inherited as an autosomal recessive trait. Vitamin E deficiency often occurs secondary to disorders that impair the absorption of vitamin E from fat including liver disorders, disorders of fat...
