There isn't a claim stating which is more severe between cough variant asthma and classic asthma. Cough variant asthma is a specific type of asthma characterized primarily by a dry cough, particularly noticeable at night. Patients usually do not exhibit significant symptoms of chest tightness, wheezing or difficulty in breathing. Typical asthma symptoms include paroxysmal coughing, chest tightness, wheezing, and difficulty in breathing. If respiratory failure occurs, along with cyanosis of the skin and mucous membranes, headaches, dizziness, or even coma, the condition is considered severe and immediate emergency treatment is necessary.
