Dr. Brad Bobrin
Psychiatry 26 years experience
They can: Many febrile illnesses, especially in the elderly can cause delirium, of which delusions and hallucinations, especially visual, are symptoms.
Dr. Douglas Bey
Psychiatry 57 years experience
Yes: Can have vivid hallucinations.
Dr. Stephen Southard
Internal Medicine 15 years experience
They can: Particularly if the fever is quite high or the person with the fever has a coexisting compromise of the brain like any of the forms of dementia. Remember though, it's not that common for healthy adults with a fever to hallucinate and may suggest a primary infection involving the brain or connective tissue around the brain.
