A [intlink id=”373″ type=”post”]nonorganic[/intlink] laryngeal disorder that manifests as breathing difficulty. Typically the individual with this disorder has failed to respond appropriately to asthma and other medicines. He or she continues to make noises that are primarily or exclusively inspiratory, in contrast to asthma. Not infrequently, individuals with VFD are treated for years as having asthma before the diagnosis of VFD is finally made.
