Ataxia means without coordination. People with ataxia lose muscle control in their arms and legs, which may lead to a lack of balance, coordination, and trouble walking. Ataxia may affect the fingers, hands, arms, legs, body, speech, and even eye movements.
The symptom of ataxia can be caused by stroke, multiple sclerosis, tumors, alcoholism, peripheral neuropathy, metabolic disorders, and vitamin deficiencies. In these cases, treating the condition that caused ataxia may improve it.
While the term ataxia usually describes symptoms, it also describes a group of specific degenerative diseases of the central nervous system called the hereditary and sporadic ataxias:
The defective gene makes abnormal proteins that cause the nerve cell degeneration. As the disease progresses, muscles become less and less responsive to the commands of the brain. This causes balance and coordination to worsen.
Symptoms and time of onset may vary according to the type of ataxia. Each person may experience symptoms differently.
Typically, the most common are listed below:
The symptoms of ataxia may resemble other conditions or medical problems. Always consult your health care provider for a diagnosis.
In addition to a thorough medical history, family history, and complete neurological and physical exam, the following diagnostic procedures may be done:
These diagnostic procedures may also be used to rule out other conditions that can cause ataxia. Certain conditions can cause ataxia to develop suddenly, such as head injury, stroke, brain hemorrhage, brain tumor, congenital abnormalities, infections, post exposure to certain drugs, and also if the heart or breathing slow or stop.
Some conditions can cause ataxia to appear gradually, such as hypothyroidism, certain vitamin deficiencies, exposure to certain drugs, multiple sclerosis, syphilis, and other disorders.
There is no cure for the hereditary ataxias. And, there is no medication to treat the specific symptom of ataxia.
If ataxia is due to a stroke, a low vitamin level, or exposure to a toxic drug or chemical, then treatment is aimed at treating those specific conditions.
The treatment for the lack of coordination or imbalance mostly involves the use of adaptive devices to allow the person to maintain as much independence as possible. These devices may include a cane, crutches, a walker, or a wheelchair. Physical therapy, speech therapy, and medications to help symptoms, such as tremor, stiffness, depression, spasticity, and sleep disorders may also help.
Research is being done on cerebellar and spinocerebellar degeneration, including work aimed at finding the cause(s) of ataxias and ways to treat, cure, and ultimately prevent them.

Progression of the different types of ataxia may vary with each specific syndrome. In the worst case scenario, the person may have untreatable rigidity, breathing trouble, or choking which can lead to death. Some of the most difficult symptoms include management with continuous positive airway pressure devices (CPAP), tracheostomy, or a feeding tube.
Falling or becoming chair- or bed-bound may lead to other life threatening complications, such as injury, pressure sores, infection, and blood clots. Dementia, behavioral problems, and depression may influence compliance and care. Symptom will focus on the management of the following symptoms:
There is always something that can be done to improve the quality of life of the person with ataxia.
Symptoms and time of onset may vary according to the type of ataxia. Each person may experience symptoms differently. Contact your provider if you have any of the following symptoms:
