Objective:
We attempted to investigate the relationship between migraine without aura (MwoA) and bronchial hyper-reactivity to postulate inflammation as an underlying mechanism in migraine.
Background:
Comorbidity of migraine and atopic diseases such as asthma has been an argument for suspected immune system dysfunction in migraineurs.
Methods:
Twenty patients with MwoA and 5 control subjects without history of atophy and asthma were included in study. Subjects with abnormal physical examination and chest radiographs were excluded. After a normal spirometry, methacholine bronchoprovocation test was performed in all subjects and controls according to 5 breath dosimeter methods.
Results:
Sixteen of 20 patients and 2 of 5 control subjects were women. Mean ages were 37.5 (19-56) and 33.8 (26-43) years, respectively. Methacholine bronchoprovocation test was positive in 3 patients (15%) but was normal in all controls (0%).
Conclusions:
The relationship between MwoA and bronchial hyper-reactivity may help to postulate the inflammation in migraine as an underlying mechanism.

Asthma I: Introduction
Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
Asthma-II: Pathophysiology and Classification
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
