About this trial

The goal of this clinical trial is to learn about how asthma influences brain function. The main questions it aims to answer are:

* How airway inflammation in asthma affects the brain; and, * Whether airway inflammation in asthma is related to symptoms of depression and anxiety

Over the course of 3 visits, participants will:

* Complete questionnaires * Complete computer tasks * Undergo allergy skin test and breathing tests * Give two blood samples * Give a sputum sample * Complete brain imaging scans

Researchers will compare results between participants with asthma, and participants who do not have asthma.
