Peter Greally first encountered asthma as a young boy when he would wake in the middle of the night, gasping for air. He was taken to see an eminent professor of paediatrics, who proclaimed that his symptoms were due to anxiety.

Childhood Asthma details what exactly can cause an asthmatic attack, how best to prevent one, and what to do when one occurs.
