Delirium is a frequent complication of advanced cancer. It is characterized by cognitive deficits and behavioral disturbance, and therefore can potentially result in severe symptom distress and impeded communication between patient and family and between patient and medical staff. The reversibility of delirium depends on its underlying causes. ⋯ This review examines the latter association in the light of recent studies. It also provides an outline of relevant pathophysiology and clinical assessment, a decision-making framework and a practical approach to the techniques of assisting hydration. This will hopefully help physicians and families in weighing up the merits of assisted hydration in an individual context and help them to achieve a consensus on the role of hydration that is consistent with the goals of care.
