Abstract
The neurological sign, ataxia, is defined as a disturbance in smooth coordination of movements. While ataxia is usually due to a disturbance in the cerebellum, it can be caused by abnormalities anywhere in the neuroaxis. Evaluation of ataxia requires a careful history and physical examination focused on localizing the cause. The differential diagnosis of ataxia is broad and best approached by dividing it into acute/subacute, recurrent/episodic and chronic static or progressive etiologies. Postinfectious cerebellar ataxia is the most common cause of childhood ataxia and usually has a favorable outcome. However, it is important to rule out serious and potentially life-threatening causes such as posterior fossa malignancies. Recurrent episodes of ataxia can be due to a migrainous etiology or from metabolic and genetic causes. Causes of chronic ataxia include structural, genetic or metabolic causes. Management includes symptom-based treatment to ensure safety of the child, while specific treatments usually depend on the underlying etiology.
