dysosmia

Declared dysosmia meaning

Use qualitative smell disturbance as the working scope while retaining the source's wording. Dysosmia also appears within the broader olfaction-disorders indexing vocabulary: [NLM MeSH](https://ncbi.nlm.nih.gov/mesh/68000857).

1. Does the person or source use dysosmia for altered odor quality or for smell dysfunction more broadly? definition
2. Which clinical record, terminology source or firsthand account supplies that meaning? provenance

Quality versus loss or taste

Record altered odor character, reduced smell and basic-taste complaints separately, allowing them to coexist.

1. Has odor character changed, has detection weakened, or are both reported? boundary
2. When food seems wrong, is the reported change in aroma, basic taste, mouth sensation or an unresolved combination? boundary

Parosmia and phantosmia distinction

Parosmia concerns changed perception of an odor; phantosmia concerns odor perception without an odor being present. Record the evidence for source presence or absence: [NIDCD smell disorders](https://www.nidcd.nih.gov/health/smell-disorders).

1. Which external odor, if any, is associated with the altered perception? measurement
2. What supports an absent stimulus, and could an intermittent or hidden environmental source remain? boundary

Odor transformation profile

Pair expected and experienced odor descriptions with intensity, pleasantness and perceived laterality as separate observations.

1. What did the triggering item previously smell like, and how does it smell during an episode? measurement
2. How intense and unpleasant is the perception, and is it experienced on one side or not localisable? measurement

Onset and recurrence pattern

Record first noticed change, prior smell baseline, episode duration and symptom-free intervals.

1. When did altered odor quality first appear relative to the person's previous smell baseline? provenance
2. How often do episodes occur, how long do they last, and are there symptom-free intervals? measurement

Candidate cause evidence

Maintain dated links to reported illness, injury, nasal symptoms, medication changes or exposures, distinguishing reports from clinician conclusions.

1. What illnesses, injuries, nasal changes, medicines or exposures were reported around onset? provenance
2. Is any proposed cause a temporal association, a clinical hypothesis or a documented diagnosis? boundary

Assessment coverage

Record what each assessment actually examined. NIDCD describes clinical evaluation using history, examination and supervised smell testing: [NIDCD smell disorders](https://www.nidcd.nih.gov/health/smell-disorders).

1. Which results assess odor detection, discrimination or identification, and which directly document qualitative distortion? measurement
2. What method, date and testing conditions support each result? provenance

Unresolved phenotype evidence

Preserve uncertainty when stimulus availability, sensory modality or the relationship between reports and assessments is unresolved.

1. What evidence supports the current phenotype, and what prevents a more definite classification? boundary
2. What additional history or clinician-selected assessment would address the unresolved distinction? action

Functional burden

Record specific avoided foods, disrupted activities, distress and concerns about recognising relevant odors, without assuming these occur in every case.

1. Which foods, settings or activities are avoided because of the altered smell, and what consequences are reported? measurement
2. Which tasks depend on odor recognition, and what difficulties or incidents have actually occurred? measurement

Individual response plan

Link each assessment or support action to a recorded difficulty and review target; keep any clinician-directed treatment linked to its indication.

1. What clinical review or practical support is agreed for the documented smell-related difficulties? action
2. Which changes in episode burden, food tolerance or daily function will be reviewed, and when? action
