Acute cerebellar ataxia (eh-TAK-see-uh) is a problem with the cerebellum (the part of the brain that controls the movement of muscles). It usually starts after a viral infection. Most of the time, it gets better on its own in a few weeks. Here's how to care for your child during that time.

• Support your child while they recover. It may be upsetting for them to not be able to control their movements. Remind them that the symptoms should improve soon.
• Talk to your child's teachers and school nurse. Depending on the symptoms, your child might need extra time to get to class, help with writing and typing, or an easier workload.
• Your child may need to change activities based on the symptoms. For example, if they have problems with balance, they may need to wait until feeling better before riding a bike.
• If your child has trouble with walking, keep them safe by helping with things like using stairs and crossing the street.
• Follow up as your health care provider recommends.

• has symptoms that get worse

• still has symptoms after 3 weeks
