anosmia
Let an agent explain anosmia and its causes, relay assessment, treatment and impacts from ENT and neurology sources in general terms, describe specific and congenital anosmias, and distinguish anosmia from hyposmia, parosmia and taste loss, routing people with new smell loss to clinicians.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain anosmia and its causes, relay assessment, treatment and impacts from ENT and neurology sources in general terms, describe specific and congenital anosmias, and distinguish anosmia from hyposmia, parosmia and taste loss, routing people with new smell loss to clinicians.
The loss or absence of the sense of smell, whether congenital, acquired through infection, head injury, nasal disease or neurodegeneration, or specific to particular odours such as isovaleric acid, isobutyric acid, musk or freesia flowers in specific anosmias, with merciful anosmia describing the loss that spares a person unpleasant odours; anosmia became widely known as a symptom of COVID-19 and affects safety, nutrition and quality of life.
What it is for: Not applicable; a sensory loss.
It can be explain causes and kinds; relay assessment and treatment; route to clinicians; distinguish related conditions.
Distinguishing features
Smell loss
Many causes
Specific anosmias
Safety and quality of life impact
What it looks like
Not a visible object; inability to smell.
Physical character
prevalence: about 3-5 percent - adults, estimates
COVID-19 smell loss: common early symptom note - 2020-2022
congenital anosmia: about 1 in 10000 note - estimates
How it is recognised
Loss of the sense of smell
Congenital anosmia, specific anosmias for isovaleric acid, isobutyric acid, musk and freesia, merciful anosmia
Hyposmia is reduced smell; parosmia is distorted smell; taste loss is ageusia

- How should clinical sources be linked?
- The registry entry has merged aliases naming specific odorant anosmias; should they be split off?
