Forty cases of acute childhood ataxia were retrospectively assessed for main etiologies and for factors that can be used in planning the most effective and cost-efficient management. The most common discharge diagnoses were acute cerebellar ataxia, ingestion, and Guillain-Barré syndrome, encompassing 80% of all cases. The remaining 20% included various isolated causes. Acute cerebellar ataxia was primarily seen in children less than 6 years of age who had preceding viral syndromes or varicella. Ingestions were also most frequent in children less than 6 years of age, but a second peak occurred in adolescents. History was suggestive of drug ingestion in 61.5% of cases, and in addition to ataxia, lethargy was an associated symptom. The drug screen was the most informative laboratory test, with 17 of 35 being positive. Lumbar punctures were positive in seven of 25, with pleocytosis in six and elevated protein in two. Of 26 computed tomographic scans and magnetic resonance imaging scans performed, only two were positive, one for cerebellar infarct and one for cerebral edema. Acute ataxia in childhood has multiple etiologies, but it is usually due to a benign, self-limited process. A thorough history, physical examination, and drug screen should be performed before other costly and invasive tests and before admission to the hospital. This approach may eliminate the need for hospitalization of some patients with postinfectious acute cerebellar ataxia and ingestion. Neuroimaging studies should be used judiciously in the evaluation of acute ataxia, considering their low yield. (J Child Neurol 1994;9:381-384).
