What causes Friedreich’s ataxia?
What Causes Friedreich’s Ataxia? Friedreich’s ataxia is a genetic defect that’s inherited from both parents by what’s called “autosomal recessive transmission.” The disease is linked to a gene called FXN. Normally this gene will cause your body to produce up to 33 copies of a specific DNA sequence.
What are the signs and symptoms of Friedreich's ataxia?
Signs and Symptoms. In Friedreich's ataxia (FA), the sequence and severity of symptoms varies greatly from person to person. Ataxia, or loss of balance and coordination, is usually the first symptom noticed. Other symptoms — including cardiac problems — may appear later. See Medical Management for information about dealing with these symptoms.

What tests are used to diagnose Friedreich's ataxia?
To diagnose Friedreich's ataxia, your doctor will take your medical history and do a physical exam. Specific tests to diagnose this condition may include: Imaging scans such as an MRI (magnetic resonance imaging) or a CT (computed tomography) Nerve conduction studies that use electrical impulses to check nerve activity
Can Friedreich's ataxia be prevented?
There's no way to prevent Friedreich's ataxia. Since the condition is inherited, genetic counseling and screening are recommended if you have the disease and plan on having children. A counselor can give you an estimate of your child's chances of having the disease or carrying the gene without showing symptoms.
When does Friedreich's ataxia start?
Symptoms of Friedreich's ataxia often start between ages 5 and 15, although they can develop later in life. Physical symptoms include: Trouble walking. Tiredness.
How does ataxia start?
Ataxia usually results from damage to the part of the brain that controls muscle coordination (cerebellum) or its connections. Many conditions can cause ataxia, including alcohol misuse, stroke, tumor, brain degeneration, multiple sclerosis, certain medications and genetic disorders.
What is the likelihood that his child will also develop Friedreich's ataxia?
When 2 carriers have a child, there is a 25% chance the child will develop Friedreich ataxia. Although the prevalence of the disease in the United States is about 6000 individuals, about 15 000 individuals worldwide have the disease.
What triggers Friedreich's ataxia?
Friedreich ataxia is caused by a defect (mutation) in a gene labeled FXN, which carries the genetic code for a protein called frataxin. Individuals who inherit two defective copies of the gene, one from each parent, will develop the disease.
Is Friedreich's ataxia painful?
Most people with Friedreich's ataxia develop scoliosis (a curving of the spine to one side), which may require surgical intervention. Friedreich's ataxia may also lead to chest pain, shortness of breath, and heart palpitations.
What is the life expectancy of someone with Friedreich's ataxia?
The symptoms of Friedreich's ataxia usually get gradually worse over many years. People with the condition tend to have a shorter life expectancy than normal. Many people live until at least their 30s, and some can live into their 60s or beyond.
Does Friedreich's ataxia affect the brain?
Friedreich's ataxia does not affect the part of the brain involved in cognition and learning. In most cases, FA begins during childhood, but it can present later in life, even well into adulthood. Late-onset FA can produce different symptoms and requires different medical management.
Can ataxia be caused by stress?
Episodes of ataxia and other symptoms can begin anytime from early childhood to adulthood. They can be triggered by environmental factors such as emotional stress, caffeine, alcohol, certain medications, physical activity, and illness.
Where is Friedreich's ataxia most common?
FRDA affects one in 50,000 people in the United States and is the most common inherited ataxia. Rates are highest in people of Western European descent. The condition is named after German physician Nikolaus Friedreich, who first described it in the 1860s.
Does ataxia shorten life?
Life expectancy is generally shorter than normal for people with hereditary ataxia, although some people can live well into their 50s, 60s or beyond. In more severe cases, the condition can be fatal in childhood or early adulthood. For acquired ataxia, the outlook depends on the underlying cause.
How do you test for Friedreich's ataxia?
A nerve conduction velocity test (NCV) is done by placing surface electrodes on the skin at various points over a nerve. One electrode delivers small shocks to the nerve and the others record the nerve's responses. Those responses are typically smaller than normal in people with FA, because FA damages the nerves.
How fast does ataxia progress?
Some types may remain relatively stable or even improve with time, but most will get progressively worse over many years. Life expectancy is generally shorter than normal for people with hereditary ataxia, although some people can live well into their 50s, 60s or beyond.
How long can you live with FA?
The symptoms of Friedreich's ataxia usually get gradually worse over many years. People with the condition tend to have a shorter life expectancy than normal. Many people live until at least their 30s, and some can live into their 60s or beyond.

What is Friedreich's ataxia?
Prevention. Friedreich’s ataxia is a rare genetic disease that causes difficulty walking, a loss of sensation in the arms and legs, and impaired speech. It’s also known as spinocerebellar degeneration. “Ataxia” means lack of order. There are a number of types of ataxia with a number of causes.
How many people have Friedreich's ataxia?
The disease causes damage to parts of your brain and spinal cord, and can also affect your heart. Friedreich’s ataxia affects approximately 1 in every 40,000 people. Although there’s no cure for Friedreich’s ataxia, there are several treatments available to help you cope with the symptoms.
How long does it take for Friedreich's ataxia to get worse?
Over time, Friedreich’s ataxia becomes worse. About 15 to 20 years after symptoms emerge, many people with Friedreich’s ataxia have to rely on a wheelchair. Those who have advanced ataxia might not be able to get around at all. Heart disease is the leading cause of death among people with Friedreich’s ataxia.
When does Friedreich's ataxia become fatal?
It usually becomes fatal by early adulthood. People with mild ataxia symptoms generally live longer. Late-onset Friedreich’s ataxia, which is when the disorder emerges at age 25 or over, tends to be milder and characterized by slower decline.
How many copies of DNA are produced in Friedreich's ataxia?
The disease is linked to a gene called FXN. Normally this gene will cause your body to produce up to 33 copies of a specific DNA sequence. In people with Friedreich’s ataxia, this sequence may repeat 66 to over 1,000 times, according to U.S. National Library of Medicine’s Genetics Home Reference.
When is Friedreich's ataxia diagnosed?
Friedreich’s ataxia can be diagnosed between the age 2 and a person’s early 50s, but it’s most commonly diagnosed between ages 10 and 15.
Can you get Friedreich's ataxia from genetics?
You might also have regular X-rays of your head, spine, and chest taken. Genetic testing can show if you have the defective frataxin gene that causes Friedreich’s ataxia. Your doctor might also order electromyography to measure the electrical activity in your muscle cells.
What is Friedreich's ataxia?
Friedreich’s ataxia is a rare, inherited, degenerative disease. It damages the spinal cord, peripheral nerves, and the cerebellum portion of the brain. This conditions tends to develop in children and teens and gradually worsens over time. Unsteady, awkward movements and a loss of sensation due to nerve injury develop as the disease progresses.

Why is my gait unsteady?
Unsteady, awkward movements and a loss of sensation due to nerve injury develop as the disease progresses. The condition is named after Nicholaus Friedreich, the German doctor who discovered it in the 1860s. Ataxia means impaired and uncoordinated muscle movement resulting in gait imbalance.
