Patients with cough hypersensitivity exhibit unusually low thresholds for responses to tussive stimuli, exaggerated responses to suprathreshold tussive stimuli, and report spontaneous experiences of urge-to-cough in the absence of exogenous stimulation. These aberrant responses to tussive challenge have the hallmark features of behaviours associated with a sensitized sensory system. Searching for further evidence to implicate neural sensitization in the symptomatology of cough hypersensitivity warrants consideration. If up-regulation of neural circuits involved in processing of airways inputs can be demonstrated in patients with cough hypersensitivity, then strategies to reverse this dysfunc..View full abstract
