Qualitative smell disorders cannot be measured and are disorders in which there is alternation or distortion in the perception of smell. Qualitative disorders include parosmia (also called troposmia) and phantosmia. [2] Dysosmia is a qualitative olfaction disorder and includes both parosmia and phantosmia.
Phantosmia (phantom smell), also called an olfactory hallucination or a phantom odor, [1] is smelling an odor that is not actually there. This is intrinsically suspicious as the formal evaluation and detection of relatively low levels of odour particles is itself a very tricky task in air epistemology.
The term derives from the Neo-Latin anosmia, based on Ancient Greek ἀν- (an-) + ὀσμή (osmḗ 'smell'; another related term, hyperosmia, refers to an increased ability to smell). Some people may be anosmic for one particular odor, a condition known as "specific anosmia". The absence of the sense of smell from birth is known as congenital ...

“But they smell bad all the time,” not just when you sneeze, Ramakrishnan says. A less likely explanation is phantosmia, when you smell something that isn’t there, he adds.
The defining feature of ORS is excessive thoughts of having offensive body odor(s) which are detectable to others. The individual may report that the odor comes from: the nose and/or mouth, i.e. halitosis (bad breath); the anus; the genitals; the skin generally; or specifically the groin, armpits or feet.
One method used to diagnose parosmia is the University of Pennsylvania Smell Identification Test (UPSIT). "Sniffin' Sticks" are another diagnostic method. [11] These techniques can help deduce whether a specific case of parosmia can be attributed to just one stimulating odor or if there is a group of odors that will elicit the displaced smell.
Bad breath, also known as halitosis, is a symptom in which a noticeably unpleasant breath odour is present. [1] It can result in anxiety among those affected. [1] It is also associated with depression and symptoms of obsessive compulsive disorder. [1] The concerns of bad breath may be divided into genuine and non-genuine cases. [2]
