Definition

Acute cerebellar ataxia is a disorder of the nervous system marked by the sudden onset of a disturbance in muscle coordination, especially in the trunk, arms, and legs.

The cerebellum is the part of the brain that controls balance and coordination. It does not function properly in the case of cerebellar ataxia. Although the abnormality of the limbs is most often noticed, it can also cause abnormal eye movements. Nausea and vomiting may also occur as part of the disorder.

While it can occur at any age, acute cerebellar ataxia is most common in young children. It can occur several weeks after a viral infection, such as chickenpox . Most cases go away without treatment in a matter of months. However, recurrent or chronic progressive cerebellar ataxia does occur.

If you suspect you or your child has this condition, call the doctor right away.
