Osmophobia is a Clinical Marker of Migraine


 

Osmophobia is a specific clinical marker of migraine, but not tension-type headache, a new study found. Researchers conducted a prospective study on 193 patients suffering from migraine without aura, migraine with aura, episodic tension-type headache, or a combination of these. Each patient was asked to describe in detail osmophobia, when present, in the 4 headache attacks. Among the findings:

  • 45.7% of migraine with aura attacks were associated with osmophobia.
  • 67.2% of patients with migraine reported osmophobia in at least a quarter of the attacks.
  • No tension-type headache attack was associated with osmophobia.
