Delirium must be ruled out first because it presents with similar symptoms as primary psychosis, but it can be caused by underlying medical conditions or medications. Dementia may also present with similar symptoms, but it typically has a gradual onset and a progressive course. Depression and delusional disorder are possible diagnoses, but they would not be ruled out before ruling out delirium.
