Acute cerebellar ataxia is a disorder of the nervous system. It is marked by the sudden onset of a disturbance in coordination. The cerebellum is the part of the brain that plays an important role in balance and coordination. It does not function properly in the case of cerebellar ataxia.
If you suspect you or your child has this condition, call the doctor right away.
Causes of acute cerebellar ataxia include:
Causes of recurrent or chronic acute ataxia include:
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.
These factors increase the chances of developing acute cerebellar ataxia:
Do not assume the following symptoms are due to acute cerebellar ataxia. These symptoms may be caused by other conditions.
Your doctor will ask about your symptoms and medical and family history. A physical exam will also be done. Your limb coordination will be observed to assess the degree and nature of the ataxia.
Further tests may include:
The ataxia that occurs in children can often can go away in a few months without any treatment. In cases where an underlying cause is identified, your doctor will treat the cause.
In some cases, you may have continuing and disabling symptoms. Treatment includes:
Drug treatment to improve muscle coordination has a low success rate. However, the following drugs may be prescribed:
Occupational or physical therapy may also play a role in alleviating lack of coordination. Changes to diet and nutritional supplements may also help.
There is no way to prevent acute cerebellar ataxia except to vaccinate children against viral infections that increase their risk of getting this condition.
