Severe Asthmatics
Individuals with severe asthma that are already enrolled in the University of Wisconsin Severe Asthma Research Program III study will fill out asthma and psychological questionnaires (non-diagnostic), will undergo Cognitive Function Testing (non-diagnostic), and will undergo a simulated and actual functional Magnetic Resonance Imaging (research grade) scan.
