What Is Friedreich’s Ataxia?
Friedreich’s ataxia is a rare inherited condition that affects the nervous system. It damages nerve pathways that help control movement, balance, and coordination. Over time, this can make walking and everyday activities more difficult.
Symptoms often begin during childhood or the teenage years and gradually worsen as the condition progresses. Friedreich’s ataxia can also affect the heart, muscles, and other parts of the body.
Symptoms
Friedreich’s ataxia develops because of a change in the FXN gene passed down from both parents. The condition is inherited in an autosomal recessive pattern, meaning a child must inherit the altered gene from each parent to develop the disease.
Symptoms can vary from person to person, but may include:
- Trouble with balance and walking
- Muscle weakness
- Fatigue
- Numbness or reduced feeling in the arms and legs
- Loss of reflexes
- Slurred speech
- Vision or hearing problems
- Curving of the spine (scoliosis)
- Foot deformities
Some people also develop heart problems or diabetes related to the condition.
How Is It Diagnosed?
A healthcare provider will begin with a physical exam and review of symptoms and family history. Because Friedreich’s ataxia affects the nervous system, providers may perform tests that evaluate coordination, balance, reflexes, and sensation.
Additional testing may include:
- Genetic testing
- MRI scans
- Nerve conduction studies
- Blood tests
- Heart testing, such as an electrocardiogram (ECG) or echocardiogram
These tests help confirm the diagnosis and identify related complications.
How Is It Treated?
There is currently no cure for Friedreich’s ataxia, but treatment can help manage symptoms and support daily function. Care plans are tailored to each person’s needs and may change over time as symptoms progress.
Treatment options may include:
- Physical therapy to improve strength and mobility
- Occupational therapy for daily living support
- Speech therapy for communication difficulties
- Braces or mobility devices for stability and movement
- Surgery for scoliosis or foot problems when needed
Providers may also treat related conditions such as heart disease or diabetes. Emotional support, counseling, and community resources can help individuals and families cope with the challenges of living with a chronic condition.
