Olfactory Hallucination

By Renée Grinnell

Smelling something that isn’t present in the surrounding environment. Also known as phantosmia. Can be caused by seizures, brain injury, or psychiatric illnesses such as schizophrenia.

Example: The patient complains of an intensely foul odor, which nobody else in the room can detect. A few minutes later, the patient has a seizure.
