Neurogenic Cough.

Neurogenic cough is a diagnosis of exclusion characterized by laryngeal hypersensitivity. More common etiologies of chronic cough should be systematically excluded prior to diagnosis. Although the pathophysiology of neurogenic cough is not fully understood, proposed etiologies typically involve injury to the vagus nerve. Treatment options include neuromodulating medications, behavioral cough suppression therapy, and procedures such as superior laryngeal nerve block. Newer targeted treatments, including P2X3 antagonists, may offer effective treatment alternatives moving forward.
