To do this, they evaluated 25 patients with seasonal allergic rhinitis and 26 healthy controls before and after nasal allergen provocation. These subjects were evaluated with a battery of objective cognitive tests and subjective questionnaires. They evaluated sustained attention, short and long-term memory, and speed of information processing. They found that sustained, but not short term, cognitive performance was impaired in allergic rhinitis patients after nasal pollen challenge. Reference Hartgerink-Lutgens I.
