Abstract
Poor asthma control or asthma exacerbation can cause hypoxia, which may be associated with cognitive impairment. 1 Caldera-Alvarado G Khan DA Defina LF Pieper A Brown ES Relationship between asthma and cognition: the Cooper Center Longitudinal Study.

In addition, an association between olfactory dysfunction and cognitive impairment has been found in recent studies. 6 Dintica CS Marseglia A Rizzuto D et al.

We hypothesized that olfactory and cognitive functions would be related to each other in patients with asthma, and they also might be associated with asthma control. Therefore, we aimed to evaluate this association in patients with asthma.
