"It's like drowning, but not in the water," says Brittle Asthma patient, Camden Brown. Brittle asthma is a rare form of severe asthma. The term "brittle" means difficult to control. Brittle asthma is unstable and unpredictable because it can suddenly develop into a life-threatening attack. Specialists at Renown Children's Hospital help keep care close to home for Renown’s youngest patients thanks to the generous support of the Pennington Foundation.
