Non-genetic ataxia:

These types of ataxia can be caused by diseases such as multiple sclerosis, strokes, brain tumors, heat stroke, or infections. Other types of non-genetic ataxia may be caused by exposure to alcohol, drugs, medicines, or other chemicals. Some types of non-genetic ataxias may be due to vitamin deficiencies or problems with the immune system. Doctors will often look for these non-genetic causes first because some types of non-genetic ataxia may be treatable.

Hereditary ataxia:

Hereditary means that the ataxia is caused by a change in the genetic instructions that tell our cerebellum how to work. These genetic changes can be passed through families. There are different types of hereditary ataxia:

• Autosomal dominant
• Autosomal recessive
• X-linked
• Mitochondrial

Sporadic ataxia:

Sporadic means that there is no single genetic or environmental cause of the ataxia. Sporadic ataxias may be due to the interaction of many genetic risk factors with many environmental exposures. While we do not understand the causes of sporadic ataxias today, many people are working to understand the genetic risk factors and environmental exposures that can cause sporadic ataxia.

The University of Minnesota Ataxia Center provides specialized evaluation, testing, and treatment for people with cerebellar ataxia. Our team of genetic specialists and ataxia experts help patients with ataxia learn more about their condition and manage it better. In addition to testing and counseling, we provide medical treatment and physical therapy focused on the needs of people with ataxia including gait imbalance, evaluation of the risk of falling, and individualized strategies for coping.
