Friedreichs Ataxia

Overview

Friedreich's ataxia (FA) is a rare inherited condition that slowly damages parts of the nervous system and can affect the heart. It mainly causes problems with balance, walking, and coordination. 'Ataxia' means loss of control of body movements. FA is not contagious and is not caused by anything a person did.

It is rare. In many populations it affects about 1 in 50,000 people, though numbers vary by region.

FA affects males and females equally. First symptoms usually appear before age 25, most often in childhood or the teen years. It is more common in people of European ancestry. A person is born with FA; it does not develop from lifestyle choices.

Symptoms

Common symptoms

• Balance and walking problems, often with a swaying or unsteady walk
• Frequent falls or clumsiness
• Trouble with hand coordination, such as handwriting or buttons
• Slurred or slow speech
• Tiredness and low energy
• Curved spine (scoliosis)
• High arches or other foot shape changes
• Heart symptoms such as palpitations, chest discomfort, or shortness of breath
• Swallowing problems later in the condition

Symptoms in children

• Difficulty running, hopping, or keeping up in play
• Frequent falls or an awkward walk
• Trouble with handwriting or fine hand tasks
• Slurred speech or slower speech
• Tiredness during school or play
• Curved spine noticed during growth spurts
• Heart changes found during a check-up

Symptoms in older adults

• Late-onset FA is less common; balance and walking problems may be the first sign
• Speech or hand coordination problems may appear
• Heart problems can still occur and need checking
• New balance problems in adults have many possible causes, so a doctor should assess them

Causes

Main causes

• FA is caused by inherited changes in both copies of the FXN gene.
• Each parent usually carries one changed copy and one working copy. Carriers do not have symptoms.
• The changed gene reduces frataxin, a protein that helps mitochondria (the energy factories in cells) work properly. Nerve cells and heart muscle are especially affected.

Risk factors

• Having a brother or sister with FA
• Having two parents who are carriers of the FXN gene change
• Parents who are close blood relatives have a higher chance of sharing the same gene change, but FA can occur in any family
• Most people with FA have no obvious family history before diagnosis

When to see a doctor

See a doctor urgently if:

• New chest pain, fainting, or severe breathing problems
• New swallowing problems with coughing or choking
• A serious fall or injury
• Sudden weakness or a sudden change in speech

Book a routine appointment if:

• Ongoing balance, walking, or coordination problems
• Frequent falls or clumsiness
• Slurred speech or handwriting changes
• A curved spine or foot shape changes
• Tiredness that does not improve
• A family history of FA or unexplained ataxia

Diagnosis

Doctors ask about symptoms and family history, examine the nerves, balance, and heart, and usually confirm FA with a genetic blood test. Other tests help rule out other causes and check the heart, spine, and blood sugar.

Tests that may be done

• Neurological exam
• Genetic blood test for changes in the FXN gene
• Nerve tests, such as nerve conduction studies
• MRI scan of the brain and spinal cord in some cases
• Heart tests, such as ECG and echocardiogram
• Blood tests for diabetes or high blood sugar
• X-rays of the spine
• Swallowing study if there are eating or drinking problems

What to expect at your appointment

You may be referred to a neurologist and a genetic counselor. Diagnosis can take time, and genetic counseling can help you and your family understand the results and what they mean.

Treatment

There is no cure for FA. Care focuses on keeping function, preventing complications, and supporting quality of life. A team may include a neurologist, physiotherapist, occupational therapist, speech therapist, heart specialist, orthopedic specialist, diabetes team, and mental health professional.

Self-care at home

• Keep a safe home with good lighting and clear walkways to reduce falls
• Use mobility aids, rails, or other equipment advised by your therapist
• Do gentle stretching and strength exercises as advised
• Plan rest breaks and avoid overexertion
• Eat a balanced diet and stay hydrated
• Take extra care with swallowing and ask for a swallowing check if meals cause coughing
• Check feet and skin regularly, especially if you wear braces or aids
• Keep routine health checks, including heart and blood sugar checks

Medical treatments

Treatment is tailored to each person. Physical therapy can help strength, balance, and walking. Occupational therapy can help with daily tasks and equipment. Speech therapy can help speech and swallowing. Heart and diabetes care are guided by specialists. Medicines may be used by specialists for heart problems, diabetes, muscle stiffness, or mood, but no single medicine treats FA itself.

When is surgery considered?

Surgery may be considered for severe spine curvature or foot problems when other care is not enough. Heart procedures depend on advice from a heart specialist. Decisions are made case by case with your healthcare team.

Living with this condition

Living with FA often means planning activities around energy levels, using aids for safety, and adjusting school or work tasks. Family, friends, teachers, and employers can help with practical support. Regular therapy and health checks help people stay as active and independent as possible.

Lifestyle tips

• Stay as active as advised with gentle exercise and physical therapy
• Keep regular sleep routines
• Eat a healthy balanced diet
• Avoid smoking and keep alcohol to a low level or avoid it as advised
• Keep vaccinations up to date as recommended
• Use seat belts and home safety measures to prevent injury
• Ask for workplace or school adjustments if needed

Diet and exercise

A balanced diet with enough fiber, calcium, and vitamin D supports general health. Exercise should be adapted to your ability and guided by a physiotherapist. Avoid very strenuous activity if you tire easily, and stop if you feel chest pain, dizziness, or severe shortness of breath. If swallowing is difficult, ask for a speech and swallowing assessment and advice on food textures.

Mental health and emotional wellbeing

Living with a long-term condition can bring worry, sadness, or frustration for the person and their family. These feelings are common and deserve support. Talk to your healthcare team about counseling or mental health support. If you or someone else is in crisis or having thoughts of self-harm, contact your local emergency services or a crisis line in your country right away.

Prevention

FA cannot be prevented after a child is born with the gene changes. Genetic counseling can help families understand the chance of FA in future pregnancies and discuss options.

Vaccines

There is no vaccine for FA. Keep routine vaccinations up to date as advised, especially to prevent infections that can worsen health.

Screening programmes

Adults with a family history may be offered genetic counseling and testing. People with FA need regular checks of the heart, blood sugar, spine, and swallowing.

Complications

If left untreated

• Worsening walking and mobility problems
• Falls and injuries
• Curved spine (scoliosis)
• Foot shape changes and foot problems
• Heart muscle weakness or heart rhythm problems
• Diabetes
• Swallowing problems and choking risk
• Speech difficulties
• Tiredness and reduced stamina
• Depression or anxiety

Long-term outlook

FA is progressive, meaning symptoms usually worsen slowly over time, but the speed varies from person to person. With regular care and support, many people live into adulthood and beyond. Some people need a wheelchair, and others remain mobile for many years. Research continues, and care focuses on safety, independence, and quality of life.
