Acute childhood ataxia is a relatively common presenting complaint in paediatric emergency settings. Because life-threatening causes of pure ataxia are rare in children, an approach in a stepwise fashion is recommended. Acute cerebellar ataxia is the most common cause of childhood ataxia, accounting for about 30-50% of all cases. Varicella ...
