Chronic Cough Despite Normal Workup

Researchers describe diagnostic evaluation and management considerations when standard testing fails to identify the cause of persistent cough.

1

A middle-aged woman experienced a persistent dry cough for 3 months, unresponsive to inhalers or over-the-counter treatments.
2

Despite normal imaging and pulmonary function tests, her cough worsened, disrupting sleep and daily activities.
3

Flexible bronchoscopy revealed marked laryngeal hypersensitivity, a key finding in diagnosing her condition.
4

Cough-predominant laryngeal hypersensitivity syndrome is characterized by heightened laryngeal cough reflex responsiveness.
5

Management includes conservative strategies like patient education, hydration, and referral to smoking cessation programs.
