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.
Main research question and why it is important: Our aim is to estimate the frequency of osmophobia in migraine and tension-type headache. The significance of the result lies in the possible use of osmophobia as a diagnostic tool in the diagnostic criteria for migraine. -Main Report (based on the above main research question): This is a prospective, non-interventional, six-month longitudinal study in which patients visiting the headache clinic will undergo a special semi-structured interview specific to headaches, in accordance with the electronic program of the Greek Headache Society (individual, family, frequency and duration of attacks, intensity of pain), which includes the MIDAS (Migraine Disability Assessment) and HIT-6(Headache Impact Test) scales. They will be given a special headache diary and a special diary for osmophobia, which they will complete and reassess over a period of 6 months. -Study tools: Headache diary, Specialised osmophobia diary, MIDAS(Migraine Disability Assessment), HIT-6(Headache Impact Test), BECK depression scale, Written consent form The migraine diary includes specific information about the nature of each attack (duration, intensity, presence of aura, worsening with activity) and the presence of accompanying symptoms (nausea, vomiting, photophobia, phonophobia), while the osmophobia diary specifies the characteristics of osmophobia (intensity, duration, temporal correlation with headache, type of odors, whether or not odors cause headache). The MIDAS and HIT-6 scales determine quality of life in migraine, and the BECK scale determines mood status.

The frequency of osmophobia in migraine and tension-type headache
Our aim is to estimate the prevalence of osmophobia in migraine and tension type headache in order to clarify its significance as a diagnostic tool for migraine
Time frame: At baseline assessment over a six month period
The correlation of osmophobia with headache type and symptoms and the calculation of its sensitivity and specificity
Our secondary aim is to estimate the correlation of osmophobia with the type and characteristics of migraine and tension-type headache, e.g. with accompanying symptoms such as nausea or vomiting, but also with comorbidities such as depression disorders. In addition, the sensitivity and specificity of osmophobia as a diagnostic criterion for migraine, as well as the sensitivity, specificity, positive and negative predictive values will be calculated for each different accompanying symptom of migraine.
Time frame: At baseline assessment over a six month period
