What to do if my grandfather has delirium, i need help, don't know where to ask else?

Should resolve: Delirium can have many causes in the elderly. It is a medical emergency. Once the underlying cause is found and treated, the confusion will resolve, although it may take many months. Orienting the person, having companionship and familiar surroundings are all helpful. The doctor may need to prescribe medication for agitation or irritability until the condition improves.
