Ataxia is a term for a group of disorders that affect co-ordination, balance and speech.
Any part of the body can be affected, but people with ataxia often have difficulties with:
The exact symptoms and their severity vary depending on the type of ataxia a person has.
There are many different types of ataxia, which can be divided into three broad categories:

Ataxia usually results from damage to a part of the brain called the cerebellum, but it can also be caused by damage to other parts of the nervous system.
Hereditary ataxia is caused by a faulty gene passed on by family members, who may or may not be affected.

In most cases, there's no cure for ataxia and supportive treatment to control the symptoms is necessary.
This may include:
In a few cases, it's possible to improve ataxia or stop it getting worse by treating the underlying cause.

The outlook for ataxia can vary considerably and largely depends on the type of ataxia you have. 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. In more severe cases, the condition can be fatal in childhood or early adulthood.
For acquired ataxia, the outlook depends on the underlying cause. Some cases may improve or stay the same, while other cases may get gradually worse over time and reduce life expectancy.
If you have ataxia, your clinical team will pass information about you on to the National Congenital Anomaly and Rare Diseases Registration Service (NCARDRS).
This helps scientists look for better ways to prevent and treat this condition. You can opt out of the register at any time.
