Perceived smell without any odor present is called what?

• A. Hyposmia
• B. Anosmia
• C. Phantosmia
• D. Hyperosmia

Answer: (C)

Perceived smell without any actual odor present is called phantosmia, an olfactory hallucination. This occurs when the brain detects a smell that isn’t coming from the environment. It can be triggered by various conditions such as temporal lobe activity (including seizures), migraines, head injury, viral infections affecting the nasal passages, or other neurological or nasal issues. The smells described are often unpleasant—burning, smoky, foul, or chemical—but can vary. Because this is a sensory experience generated by the brain rather than by an external odor, it may be temporary or persistent, and it warrants evaluation if it’s new, recurrent, or associated with other neurological symptoms. Treatment focuses on identifying and addressing the underlying cause, with management tailored to the specific condition involved.
