Causes of Ataxia

Ataxia has many causes. It maybe hereditary. Other causes include, stroke, infection, intoxication with alcohol and drugs, tumours, multiple sclerosis, AIDS and lack of vitamins.

In some cases, ataxia may be present from birth. Such conditions include Dandy Walker syndrome, Joubert syndrome, Rhombencephalosynapsis and cerebral palsy. In other cases it may develop later in life where it may appear either suddenly or gradually.

Causes of sudden onset ataxia that appears over hours or days include -

  • Stroke or trauma affecting the cerebellum or associated organs.
  • Bacterial or viral infections of the cerebellum including abscess. Ataxia may occur even after infection due to inflammation, for example after chicken pox infection.
  • Intoxication with alcohol and drugs such as barbiturates and phenytoin.
  • High fever, seizures and migraine. This type of ataxia occurs only during the attack and is called intermittent ataxia.

Causes of ataxia that appears over days to weeks include –

  • Tumours – Tumours can exert pressure on structures important in maintaining balance and coordination.
  • Multiple sclerosis.
  • Intoxication with mercury and some chemotherapy drugs.
  • Lack of vitamin B1 and B12.
  • Lack of vitamin E.
  • AIDS related brain disease.
  • Lyme disease.

Causes of ataxia that appears over months to years include -

  • Inherited disease - Spinocerebellar ataxias, Friedreich’s ataxia, Ataxia telangiectasia, multiple system atrophy, coenzyme Q deficiency, Wilson’s disease, congenital cerebellar ataxia.
  • Low thyroid hormone levels (hypothyroidism).
  • Tumours - Some tumours like breast, lung and ovarian tumours as well as Hodgkin’s lymphoma can also cause ataxia. In these cases, the body produces some substances called antibodies that damage the cerebellum.
  • Advanced syphilis.

I cannot walk a straight line. It was so bad Sunday that I went to the hospital to see if I had a stroke. No stroke, no MS, taking meds for heart attack back in December. Doctors don't know what is causing it. Very frustrated.

I got ataxia from interferon shots. Collapsed one day, wound up in hospital for 2 weeks in a coma, had pneumonia, anemia requiring transfusion, dysphagia, dyskinesia and dysarthria, After 3 months of therapy speech is still affected and still cannot walk w/o qualified supervision. Are there any treatments available?

For the last two months, I have had Bacteremia four times with E-Coli ESBL, and Proteus. I have been covered extensively with Gentamicin and Vancomycin. My Creatinine has been rising and is now 131. My GFR has been decreasing, which is now 38. As well, I have lost my sense of balance and I am experiencing a great deal of difficulty walking. Initially I thought this was due to severe anemia, HGB 88, with iron depletion. Now I wonder about ataxia from the aminoglycocides, and if this is the case, is it reversible?
