What is ataxia and its types?

Ataxia is a term used for a group of neurological conditions. There are several types of ataxia, including: ataxia telangiectasia (AT), episodic ataxia, Friedreich’s ataxia, multiple system atrophy (MSA) and spinocerebellar ataxia. This condition happens when the part of the brain called the cerebellum is damaged.

What is ataxia test?

Genetic testing involves taking a sample of blood and testing the DNA in it for any genetic mutation known to cause ataxia. Currently, tests can detect the mutations responsible for Friedreich’s ataxia, ataxia-telangiectasia and most of the spinocerebellar ataxias.

Can dehydration cause ataxia?

Chronic lithium use is associated with ataxia that is often permanent. Symptom onset tends to occur after infection, dehydration, or renal dysfunction.

How do I know if I have alcoholic ataxia?

Alcohol is a cause of late cortical cerebellar degeneration of the anterior lobe. 1-3 These patients typically exhibit ataxia of the lower limbs, ataxia of gait, and trunk instability. Less frequent clinical findings include nystagmus, dysarthria and upper limb incoordination.

What is ataxia and what are the symptoms?

Ataxia is a rare neurological disease. It is progressive – affecting a person’s ability to walk, talk, and use fine motor skills. What is Ataxia? Ataxia is a degenerative disease of the nervous system. Many symptoms of Ataxia mimic those of being drunk, such as slurred speech, stumbling, falling, and incoordination.

What is the prevalence of ataxia telangiectasia (AT)?

Ataxia telangiectasia (AT) is the most common form of infantile-onset cerebellar ataxia, with a prevalence estimated at 1-2.5 per 100,000. In the classical form of AT progressive gait unsteadiness begins in the second year of life, soon after beginning to walk. Slurring of speech and hand incoordination follow soon afterward.

How often does episodic ataxia occur?

Episodic ataxia: With episodic ataxia, people have recurring troubles with movement and balance. These episodes can happen multiple times per day, or just one or two times a year. Episodic ataxia can develop at any age. Its causes include stress, medications, alcohol, illness, and physical exertion.

What is the prevalence of Friedreich’s ataxia?

Friedreich’s ataxia (FRDA) which represents out 1/2 of all cases of hereditary ataxia has a prevalence of 2-4/100,000 and is the most common form of hereditary ataxia. The classic form has an age of onset between 2-25 years, and about 25% have an atypical presentation with milder phenotype and onset after 25 years.
