Nonallergic Rhinitis: Diagnosis

Nonallergic rhinitis (NAR) is one of the most common conditions in medicine, affecting the quality of life of millions of patients throughout the United States. Despite its ubiquitous nature, NAR remains a poorly managed and often difficult to treat condition. NAR is often suboptimally managed by clinicians with poor clinical outcomes. Establishing the correct diagnosis requires a keen understanding of the unique underlying mechanisms involved in NAR, which is still evolving. Ultimately epidemiologic studies that better define NAR prevalence and its economic burden on society are needed to convince funding agencies of the need for research to elucidate mechanisms and specific treatment approaches for this condition.
