# Friedreich's Ataxia
What is it
Friedreich's Ataxia (FA) is an inherited disease in which nerve cells in the spinal cord and certain parts of the brain gradually become damaged. The word 'ataxia' means 'lack of coordination' — and that is indeed what happens: muscle control worsens step by step.
The disease is caused by a defect in genetic material (DNA) and usually appears in puberty or early adulthood, although there is variation. It is a progressive condition, meaning that symptoms gradually worsen over the course of years. FA belongs to the group of inherited neurodegenerative diseases — illnesses in which nerve cells slowly deteriorate.
It is important to know that FA is rare. In the Netherlands, approximately one hundred to two hundred people have this diagnosis.
Causes
FA arises from a fault in the gene that codes for a protein called 'frataxin'. This protein plays a role in the energy management of cells, especially in nerve cells. Without functioning frataxin, those cells cannot manage their energy properly, and toxic substances accumulate.
The disease is **autosomal recessive**, which means you must inherit two copies of the defective gene — one from your mother and one from your father — to develop FA. If your parents are both carriers (but not sick themselves), they each have a 50% chance of passing on the gene. This gives their children each a 25% chance of developing FA.
The genetic defect occurs before birth, but symptoms may appear years later.
How the disease progresses
FA progresses in a predictable pattern, although the speed varies from person to person.
**Early stage (years 1-5 after symptom onset)**
Restlessness and balance problems increase. People notice that they must walk more carefully, stumble more often, and that stairs or uneven ground become more difficult. Fine motor skills — such as writing or fastening buttons — can also become harder.
**Middle stage (years 5-15)**
Walking problems worsen. Many people need a walker or wheelchair around 10-15 years after the first symptoms. The arms and hands also become less mobile. Speaking can become somewhat less clear, and chewing ability may decline.
**Later stage**
The disease largely stabilizes. Physical limitations are significant, but many patients live for years or decades in this phase. This is also when heart problems can become more apparent.
Symptoms by phase
**Movement and coordination (present in all stages)**
- Balance problems and unsteady gait (often the first symptom)
- Spastic legs (stiffness and spasms)
- Tremor (shaking) of hands and head
- Difficulty with fine motor skills (writing, buttons)
- Loss of proprioception (sense of where your body parts are in space)
**Speech and swallowing (appear as the disease progresses)**
- Unclear speech
- Difficulty swallowing (dysphagia)
- Throat fatigue or voice fatigue during speaking
**Eyes**
- Eye movement problems (nystagmus)
- Vision deterioration
- Sensitivity to light
**Heart**
- Thickened heart muscle tissue (hypertrophic cardiomyopathy)
- Rhythm disturbances (arrhythmias)
- Heart failure (in later stages)
- These heart problems are one of the most serious complications
**Other**
- Concentration and memory problems can occur, but severe dementia is **not** typical of FA
- Diabetes or blood sugar regulation can worsen
- Loss of nerve function in feet and hands (peripheral neuropathy)
What it means for daily life
In the early stage, many people still have relatively much freedom, although they must walk more carefully and fall risks can increase. Many young people with FA continue to attend school and university, though sometimes with accommodations.
As the disease progresses, aids become necessary: first a walking stick or walker, later a wheelchair. Independent living becomes more difficult. Many people eventually need assistance or home care for daily tasks.
Work is sometimes still possible in the early stages, especially in professions where physical strength is less important. But many people have to adapt their work step by step or stop working.
Social interactions can become more difficult due to speech problems, but people with FA usually have full mental capacity. This is important for relationships and social contacts.
Driving will eventually become impossible due to motor problems.
Heart problems require regular monitoring and may require medication. This is a point of attention that must be closely monitored.
Outlook
FA is a condition that does not heal, and current treatments cannot reverse the underlying disease. They can help relieve symptoms and slow down some complications.
Caution is advised regarding life expectancy. Medical data show that people with FA have an average lower life expectancy than the general population, especially due to heart complications. However: these figures say nothing about one person. Many factors — how quickly the disease progresses, how well the heart functions, how well care is organized — play a role.
**Research and treatment options**
In recent years, research has accelerated. Various treatments are being investigated or have been recently approved:
- Certain medications aimed at antioxidant processes (to protect cells against harmful substances)
- Physiotherapy and rehabilitation, which help maintain muscle strength as long as possible
- Heart monitoring and possible treatment of heart problems
- Speech and language therapy when speaking and swallowing become more difficult
Research focuses, among other things, on ways to better regulate iron uptake in cells, on gene silencing, and on protection of nerve tissue. This field is moving, but not all of these studies have yet led to practical applications.
Frequently asked questions
**Is FA hereditary for my children?**
Yes, the disease is inherited, but that only happens if both parents are carriers (homozygous recessive). If you have FA and your partner is not a carrier, your children will inherit the gene but (probably) will not get sick — they are carriers. It is wise to discuss this in a genetic consultation, especially if you want to have children.
**Can FA be prevented?**
No, you cannot prevent FA if you have the hereditary predisposition. However, through genetic testing and counselling, you can test involved family members, so they know whether they are carriers.
**Can FA go into remission or stabilize?**
The disease progresses step by step, and the direction is usually forward (more limitation). Stabilization can occur — there are long periods in which symptoms worsen more slowly. Complete reversal of damage is not possible.
**Which specialists should I consult?**
FA usually involves several specialists: a neurologist (for overall monitoring), a cardiologist (due to heart risk), and depending on symptoms, a physiotherapist, speech therapist, and others. A multidisciplinary team in a specialist centre often works best.
