This disorder primarily affects teenagers, but can occur at any age. Typically patients will develop a “wheeze” that is really stridor upon breathing in while exerting themselves in a sport. These kids are nearly always treated for asthma (most do not have asthma). PFT (pulmonary function tests) are often normal. Diagnosis and treatment with a team approach with our speech pathologists often leads to complete cure of this disorder.
