Chronic cough | EPFL Graph Search

Chronic cough is long-term coughing, sometimes defined as more than several weeks or months. Generally a cough lasting for more than eight weeks for an adult would meet the clinical definition of a chronic cough; and for children this threshold is lower (some studies suggest that a chronic cough must persist upwards of three months). The term can be used to describe the different causes related to coughing, the three main ones being upper airway cough syndrome, asthma and gastroesophageal reflux disease. It occurs in the upper airway of the respiratory system. Generally, a cough lasts around one to two weeks; however, chronic cough can persist for an extended period of time defined as six weeks or longer. People with chronic cough often experience more than one cause present. Due to the nature of the syndrome, the treatments used are similar; however, there are a subsequent number of treatments available, and the clinical management of the patients remains a challenge. Common symptoms present in chronic cough include a runny or stuffy nose, a feeling of liquid running down the back of the throat (postnasal drip), frequent throat clearing (coughing) and sore throat, hoarseness, wheezing or shortness of breath, heartburn or sour taste in a person's mouth, and in rare cases coughing blood. Long-term coughing and constant irritation of the upper airway can be problematic for individuals who have chronic cough. Due to the consistent coughing, this can interfere with an individual's daily life. This interference can thus cause additional problems such as affecting a person's ability to ensure a consistent sleep, daytime fatigue, difficulty concentrating at work or school, headache, and dizziness. Other more severe but rare complications include fainting, urinary incontinence, and broken ribs, caused by excessive coughing. Possible causes, alone or in conjunction, that produce the chronic cough include the following. Postnasal drip, when excess mucus is produced in the sinus of the nose and drips back towards the throat, causes a cough reflex, also known as upper airway cough syndrome.

How to Count Coughs: An Event-Based Framework for Evaluating Automatic Cough Detection Algorithm Performance
