Introduction:
In patients reporting acute headache after sneezing or coughing, rupture of an intracranial aneurysm is the first diagnosis to be considered. Sneezing, however, might also be a trigger for migraine attacks, as exemplified in our case.
Case Report:
We describe a patient who suffered 3 headache attacks after sneezing, each fulfilling criteria of migraine without aura. Sneezing as a specific trigger for migraine has not been described before.
Discussion:
The differential diagnosis of acute headache after sneezing (eg, subarachnoid hemorrhage and reversible cerebral vasoconstriction), and the differences between migraine after sneezing and "benign cough headache" are discussed. We conclude that a pathophysiological association between migraine and sneezing might exist and hypothesize on underlying mechanisms.

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.

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by anesthetizing...
