What does a person with ataxia look like?

Ataxia means without coordination. People with ataxia lose muscle control in their arms and legs. This 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.

What is sporadic ataxia?

Sporadic ataxia is a term designating a group of. diseases of the central nervous system that occur. without evidence that they are inherited, that is, no. other person in the affected individual’s family has. ever had the same disorder.

What causes sporadic ataxia?

People with sporadic ataxia have symptoms that usually begin in adulthood but no known family history of the disease. Sporadic ataxias may result from a new abnormality of the gene or as a result of an underlying disease, including thyroid disease, chronic hypoglycemia, stroke, and vitamin deficiencies.

Can ataxia symptoms come and go?

Symptoms can be sudden and brief (acute) or can occur slowly and be long-lasting (chronic). Cerebellar ataxia can come and go or get progressively worse over time.

Can inner ear problems cause ataxia?

The most common causes of ataxia are alcohol and drug use, inflammation of the inner ear (labyrinthitis), and stroke. Ataxia can also be caused by other problems, such as ear infections, benign paroxysmal positional vertigo (BPPH), epilepsy, or nervous system disorders, such as cerebral palsy or Parkinson’s disease.

What is sporadic onset?

Abstract. Sporadic adult-onset ataxia (SAOA) is a nongenetic neurodegenerative disorder of the cerebellum of unknown cause which manifests with progressive ataxia. It is distinguished from hereditary ataxias and from acquired ataxias.

Does ataxia show up on MRI?

Imaging studies. An MRI can sometimes show shrinkage of the cerebellum and other brain structures in people with ataxia. It may also show other treatable findings, such as a blood clot or benign tumor, that could be pressing on your cerebellum.

Does ataxia affect the eyes?

A sign of an underlying condition, ataxia can affect various movements and create difficulties with speech, eye movement and swallowing.

Can a person with sporadic ataxia be pure cerebellar?

Sporadic Ataxia can be either “pure cerebellar” if only the cerebellum is affected or cerebellar plus, if the Ataxia is accompanied by additional symptoms such a neuropathy, dementia, or weakness, rigidity, or spasticity of the muscles.

Are there different types of episodic ataxia syndrome?

Episodic Ataxia is clinically characterized by attacks of Ataxia with a clear onset of resolution. There are now eight recognized episodic Ataxia syndromes, numbered 1-8, in addition to late onset episodic Ataxia. The genes are known for EA1, EA2, ES5, and EA6.

Can a person with ataxia have no family history?

Because a single recessive Ataxia gene does not cause symptoms, it can be passed on in a family for generations without being recognized. Therefore, there can appear to be no “family history” of Ataxia if the disease was inherited as a recessive gene.

How are people with ataxia diagnosed and treated?

Ataxia is diagnosed using a combination of strategies that may include medical history, family history, and a complete neurological evaluation. Various blood tests may be performed to rule out other possible disorders which may present similar symptoms.
