Chronic nonallergic rhinitis (NAR) is not a specific disease but rather a syndrome diagnosed by excluding other specific types of rhinitis. The pathogenesis, incidence, clinical manifestations, diagnosis, and treatment of chronic NAR are presented in this topic review. Allergic rhinitis and an overview of other forms of rhinitis are presented separately. (See "Chronic rhinosinusitis: Clinical manifestations, pathophysiology, and diagnosis" and "Pharmacotherapy of allergic rhinitis" and "Allergic rhinitis: Clinical manifestations, epidemiology, and diagnosis" and "An overview of rhinitis".)


NAR is best defined by the chronic presence of one or more of the four following cardinal symptoms of rhinitis, in the absence of a specific etiology (such as an immunologic, infectious, pharmacologic, structural, hormonal, vasculitic, metabolic, or atrophic cause):
