/PURPOSE: Headache-associated symptoms (e.g., sensory sensitivity, nausea) are used to classify primary headache disorders and define treatment outcomes. We developed Cluster Analysis of Migraine-Associated Symptoms (CAMS) to provide an aggregate measure that captures relationships between several headache-associated symptoms....

Discussion
Signed responses from readers of the wire.
No actionable change for audiologists; this cross-sectional clustering study may inform future vestibular migraine classification but does not yet change audiology practice.
Vestibular migraine overlaps significantly with audiology presentations such as sound sensitivity and dizziness; better symptom clustering could improve diagnostic precision at the audiology-neurology interface.
- 01Cross-sectional study applied cluster analysis to migraine-associated symptoms across the lifespan.
- 02Sensory sensitivity (including phonophobia/sound sensitivity) was among symptoms analyzed.
- 03Aim was to classify headache disorders and define measurable treatment outcomes.
- 04Descriptive clustering methodology; no intervention or longitudinal follow-up reported.
- 05Potential future relevance for differentiating vestibular migraine from other vestibular disorders.
Cluster analysis can identify distinct symptom subgroups among migraine patients across different age groups.
