When delirium is diagnosed or suspected, the underlying causes should be sought. Despite every effort, no cause for delirium can be found in a small percentage of patients. Components of delirium management include supportive therapy and pharmacological management.
Fluid and nutrition should be given carefully because the patient may be unwilling or physically unable to maintain a balanced intake. For the patient suspected of having alcohol toxicity or alcohol withdrawal, therapy should include multivitamins, especially thiamine.
