Lung Diseases Clinical Trial
Official title:
Patterns of Neurocircuitry Activation In Severe Asthma
The overall purpose of the study is to compare the patterns of neurocircuitry activation in severe asthmatics vs. mild to moderate and healthy controls. The Investigators hypothesize that neurocircuitry activation increases with asthma severity, producing different neurocircuitry patterns for severe asthmatics than those of mild to moderate asthmatics or non-asthmatics.
To begin to further address possible relationships of asthma and brain function, the investigators propose the following hypothesis, "patients with defined characteristics of severe asthma will have distinct patterns of persistent neurocircuitry activation. The investigators further propose that the detection of ongoing neurocircuitry activation occurs because of persistent and active airway inflammation in severe asthma. Finally, the investigators propose that the intensity of specific neurocircuitry activation will relate to the severity of underlying asthma. ;
