Cough-variant asthma is not allergic asthma, although it is a type of allergic asthma. Generally speaking, there is a certain distinction between cough-variant asthma and allergic asthma. Clinically, cough-variant asthma is a special type of asthma, where the main symptom exhibited by patients is an irritative dry cough, typically quite severe, without other significant clinical discomforts. In contrast, patients with allergic asthma usually exhibit symptoms such as sneezing, nasal congestion, runny nose, itchy eyes, and itchy nose before the onset, triggered by exposure to certain allergens. Cough-variant asthma does not have these preliminary signs, marking a clear difference from allergic asthma.
