Updated on April 23, 2026

Ataxia is a potential side effect of certain medications, especially barbiturates, such as phenobarbital; sedatives, such as benzodiazepines; antiepileptic drugs, such as phenytoin; and some types of chemotherapy. Vitamin B-6 toxicity also may cause ataxia.

Does drug induced ataxia go away?

In general, drug-induced ataxia is reversible after discontinuing the drug or lowering the dosage, but in some cases symptoms may persist, especially with lithium, phenytoin, and cytarabine.

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 causes ataxia?

Ataxia is usually caused by damage to a part of the brain known as the cerebellum, but it can also be caused by damage to the spinal cord or other nerves. The spinal cord is a long bundle of nerves that runs down the spine and connects the brain to all other parts of the body.

How quickly does ataxia progress?

The age of onset and the rate of ataxia progression are perhaps the two most useful clinical features pointing to the cause. Rapid progression (within weeks to months) is characteristic of paraneoplastic spinocerebellar degeneration and sporadic Creutzfeldt-Jakob disease.

What are the early signs of ataxia?

  • Balance and coordination are affected first.
  • Poor coordination of hands, arms, and legs.
  • Slurring of speech.
  • Wide-based gait (manner of walking)
  • Difficulty with writing and eating.
  • Slow eye movements.

Can ataxia be caused by medication?

Ataxia is a potential side effect of certain medications, especially barbiturates, such as phenobarbital; sedatives, such as benzodiazepines; antiepileptic drugs, such as phenytoin; and some types of chemotherapy. Vitamin B-6 toxicity also may cause ataxia.

Can ataxia be caused by stress?

Episodes of ataxia and other symptoms can begin anytime from early childhood to adulthood. They can be triggered by environmental factors such as emotional stress, caffeine, alcohol, certain medications, physical activity, and illness. The frequency of attacks ranges from several per day to one or two per year.

How can you prevent ataxia?

ataxia with vitamin E deficiency can often be controlled or improved with vitamin E supplements. episodic ataxia can often be controlled with a medication called acetazolamide and by avoiding triggers such as stress, alcohol and caffeine.

Can vitamin E help with ataxia?

Vitamin E supplementation in AVED patients stabilizes the neurological signs and can lead to mild improvement of cerebellar ataxia, especially in early stages of the disease.

Is ataxia considered a disability?

Ataxia can be disabling, and if you are unable to work and earn a living because of the severity of the condition, you may qualify for disability benefits from the Social Security Administration (SSA).

Does ataxia worse with age?

The symptoms of episodic ataxia may disappear as a person gets older, although sometimes the condition gets gradually worse over time. Medication can often help control attacks, and life expectancy is usually normal.

Does ataxia affect memory?

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 kind of doctor treats ataxia?

The National Ataxia Foundation has compiled a list of neurologists across the United States and in some countries who see patients who have Ataxia or other movement disorders.

Is ataxia an autoimmune disease?

Autoimmune cerebellar ataxia in adults is usually of rapid onset and progression and can be divided into paraneoplastic and nonparaneoplastic disorders. The neurologic deficits are typically disabling, including dysarthria, disorders of gait and balance, and limb ataxia.

Is ataxia a symptom or a disease?

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. These symptoms are caused by damage to the cerebellum, the part of the brain that is responsible for coordinating movement.

Can Benzos cause ataxia?

Benzodiazepines cause acute adverse effects: drowsiness, increased reaction time, ataxia, motor incoordination, and anterograde amnesia.

Can statins cause ataxia?

Background: Drug-induced cerebellar ataxias (DICA) represent an important group of secondary cerebellar ataxias. Herein, we reported a case series of progressive cerebellar ataxia induced by HMG-CoA reductase inhibitors (statins).

Can antibiotics cause ataxia?

The different antibiotics were separated according to the physiopathogenic mechanism that could cause them to trigger a gait disorder. They were classified into antibiotics capable of producing cerebellar ataxia, vestibular ataxia, sensitive ataxia or an extrapyramidal gait disorder.

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.

Is there a cure for episodic ataxia?

There’s no cure for any type of episodic ataxia. Though EA is a chronic condition, it doesn’t affect life expectancy.

How long can you live with ataxia telangiectasia?

Ataxia telangiectasia is a rare, multiorgan neurodegenerative disorder with enhanced vulnerability to cancer and infection. Median survival in two large cohorts of patients with this disease, one prospective and one retrospective, is 25 and 19 years, with a wide range.

Can Vitamin B12 deficiency cause ataxia?

Vitamin B12 deficiency is common in the population over 80 (about 10%). It can be a cause of unsteady gait (ataxia), sometimes accompanied by anemia (macrocytic), and loss of position sense. When associated with spinal cord disease, it is sometimes termed “subacute combined degeneration”.

Is ataxia caused by vitamin E deficiency?

A shortage (deficiency) of vitamin E can lead to neurological problems, such as difficulty coordinating movements (ataxia) and speech (dysarthria), loss of reflexes in the legs (lower limb areflexia), and a loss of sensation in the extremities (peripheral neuropathy).

Which vitamin deficiency causes cerebellar ataxia?

Severe deficiency of Vitamin E can profoundly affect the central nervous system and can cause ataxia and peripheral neuropathy resembling Friedreich’s ataxia. Vitamin E deficiency can occur with abetalipoproteinemia, cholestatic liver disease or fat malabsorption.

Is MS similar to ataxia?

Tremor and ataxia are both symptoms of MS that impact movement. Tremor is described as an unintentional, rhythmic, muscle movement involving to-and-fro movements of one or more parts of the body. Ataxia is described as incoordination and unsteadiness which can affect posture, walking, eye movements and speech.

Is ataxia the same as MS?

Ataxia is common in MS but is also seen in several other conditions including diabetic polyneuropathy, acute transverse myelitis, vacuolar myelopathy, tumor or cord compression and hereditary forms of ataxia.

Is ataxia a death sentence?

Ataxia caused by Wobbler syndrome affects one in 100 horses, and is one of the greatest sources of missed training days and frustration for horse owners and veterinarians alike. Ataxia – a lack of voluntary muscle co-ordination – can be a death sentence for a horse.

What does ataxic gait look like?

What is Ataxic Gait? Ataxic gait is often characterized by difficulty walking in a straight line, lateral veering, poor balance, a widened base of support, inconsistent arm motion, and lack of repeatability. These symptoms often resemble gait seen under the influence of alcohol.

Does ataxia cause dizziness?

Episodic ataxia can develop at any age. Its causes include stress, medications, alcohol, illness, and physical exertion. There are seven types of episodic ataxia, all of which have unique symptoms in addition to difficulty with movement, including dizziness, headaches, blurry vision, and nausea and vomiting.

What are the symptoms of ataxia telangiectasia?

  • Decreased coordination of movements (ataxia) in late childhood that can include ataxic gait (cerebellar ataxia), jerky gait, unsteadiness.
  • Decreasing mental development, slows or stops after age 10 to 12.
  • Delayed walking.
  • Discoloration of skin areas exposed to sunlight.
