Asthma is clinically classified according to the frequency of symptoms, forced expiratory volume in one second (FEV 1), and peak expiratory flow rate. [11] Asthma may also be classified as atopic (extrinsic) or non-atopic (intrinsic), based on whether symptoms are precipitated by allergens (atopic) or not (non-atopic). [12]
Early-onset atopic asthma is the most common phenotype of asthma in childhood, called intrinsic asthma in the earlier intrinsic/extrinsic classification. Patients with early-onset atopic asthma frequently have a family history of atopy, and are sensitised to common allergens. This phenotype usually responds well to inhaled corticosteroids, and ...

The fundamental problem in asthma appears to be immunological: young children in the early stages of asthma show signs of excessive inflammation in their airways. Epidemiological findings give clues as to the pathogenesis : the incidence of asthma seems to be increasing worldwide, and asthma is now very much more common in affluent countries.
Medical treatment for restrictive lung disease is normally limited to supportive care since both the intrinsic and extrinsic causes can have irreversible effects on lung compliance. [10] The supportive therapies focus on maximizing pulmonary function and preserving activity tolerance through oxygen therapy, bronchodilators, inhaled beta ...
