Acute cerebellar ataxia
Patients typically present with rapid development of symptoms over the course of a few hours, with gait disturbance the most common symptom. Other symptoms include fine motor control problems, tremor, nystagmus, slurred speech, dysarthria, and vomiting. Fever, meningismus, and seizures are absent. Physical examination reveals a wide-based staggering gait, speech abnormalities with fluctuation in rhythm and tone, and impaired coordination as demonstrated by over / under shooting on finger-to-nose testing and difficulty with rapid alternating movements.
Prognosis is good as most children have complete resolution of symptoms within 2-3 weeks of presentation.
