Asthma is the most common chronic respiratory disease, affecting up to 10% of adults and 30% of children (JACI, 2011).

Children who are referred to specialist care with asthma that does not respond to treatment (problematic severe asthma) are a heterogeneous group.
Differential Diagnosis of Asthma in Adults
Differential diagnosis of cough, a simple mnemonic is GREAT BAD CAT TOM.
