The Prevalence of Osmophobia in Migraine and Tension-Type Headache Patients and Its Association With Migraine Symptoms Over a Period of 6 Months

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.
