Can ataxia be hereditary?

Can ataxia be hereditary?

You can inherit a genetic ataxia from either a dominant gene from one parent (autosomal dominant disorder) or a recessive gene from each parent (autosomal recessive disorder). In the latter case, it’s possible neither parent has the disorder (silent mutation), so there might be no obvious family history.

What gene causes ataxia?

The disease gene that causes ataxia telangiectasia, known as the ATM gene, is located on the long arm (q) of chromosome 11 (11q22. 3). Chromosomes are found in the nucleus of all body cells. They carry the genetic characteristics of each individual.

Can hereditary ataxia be cured?

There is no cure for ataxia. The outlook will depend on the type, cause, and severity. Some types of hereditary ataxia can shorten a person’s lifespan, but many people will have the same life expectancy as those without the condition.

Does ataxia cause dementia?

Dementia occurs only in some forms of spinocerebellar ataxia (SCA), such as SCA1,1 SCA2, SCA3,2 and SCA12,3 developing in the latest stages of the disease.

Does ataxia affect memory?

The cerebellum plays a role in some forms of thinking. Patients with cerebellar atrophy may have impaired recall of newly learned information or difficulty with “executive functions” such as making plans and keeping thoughts in proper sequence.

What is ataxia dementia?

The Hereditary Ataxias are a group of rare diseases characterised by degeneration of the cerebellum, brain stem and spinal cord. They vary in age of onset, mode of inheritance and severity of the symptoms.

What is the life expectancy of someone with ataxia?

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.

What is the best treatment for ataxia?

There’s no treatment specifically for ataxia. In some cases, treating the underlying cause resolves the ataxia, such as stopping medications that cause it. In other cases, such as ataxia that results from chickenpox or other viral infections, it’s likely to resolve on its own.

What are the different types of ataxia?

There are three clinical types of ataxia: sensory (proprioceptive), vestibular, and cerebellar. All three types produce changes in limb coordination, but vestibular and cerebellar ataxia also produce changes in head and neck movement.

What does it mean to have ataxia?

Ataxia is a movement disorder caused by problems in the brain. When you have ataxia, you have trouble moving parts of your body the way you want. Or the muscles in your arms and legs might move when you don’t want them to. The word ataxia actually means “without coordination.”
