The goal of this observational study is to learn about the frequency and diagnostic value of osmophobia, which is a sensitivity to smell, in people with migraine compared to those with tension-type headache. The main question it aims to answer is:
Does osmophobia reliably indicate a migraine rather than a tension-type headache?
Participants diagnosed with migraine or tension-type headache at the Headache Outpatient Department of Aeginition Hospital of Athens will record their headaches and any sensitivity to smells using a headache diary and a special osmophobia calendar over a period of six months. They will also complete questionnaires about migraine burden and related health conditions.
