This study investigates the effects of Allergic Rhinitis (AR) on driving ability and memory
functions. Our group has previously shown that patients suffering from AR symptoms perform
less well on tasks requiring sustained attention compared to non symptomatic controls. Car
driving is a typical behavior that is susceptible for changes in sustained attention and
might therefore become worse under conditions when patients suffer from AR symptoms. We will
compare the driving performance of untreated, symptomatic AR patients with the performance of
symptomatic patients that have been treated with either a systemic AR medication (a pill) or
a topical medication (nasal spray)
