Evaluation usually can be conducted on an outpatient basis. Management of recurrent sinopulmonary infections may require hospital stay and intravenous antibiotics Treatment for AT is directed toward control of symptoms. For respiratory infections, therapy with an antibiotic drug, postural drainage (with the head lower than the rest of the body) of the bronchial tubes and lungs, and gammaglobulin injections in some cases may be effective Treatment. There's no treatment specifically for ataxia. In some cases, treating the underlying cause resolves the ataxia, such as stopping medications that cause it. In other cases, such as ataxia that results from chickenpox or other viral infections, it's likely to resolve on its own
