In a new study, data was collected from 141 people with chronic cough to examine if a prior diagnosis of anxiety or depression had an influence on perceived cough severity.
Chronic Cough
Chronic cough affects 16% of Canadians between the ages of 45-85. The condition is commonly characterized by a persistent cough that lasts longer than 8 weeks. Chronic cough can significantly impact a person’s quality of life. For example, chronic cough can make it difficult to get through a conversation without coughing and may impair day-to-day activities such as sleeping.
Cough Severity Index
The Cough Severity Index (CSI) is a validated questionnaire used to assign a number that helps describe the impact of cough symptoms on an individual’s quality of life. A higher score reflects a greater perceived severity of cough.
Methods
After establishing a current diagnosis of chronic cough, patients were divided into 4 groups: patients with a diagnosis of anxiety only, depression only, anxiety and depression, and neither of these conditions. The main outcome of the study looked at CSI scores for each patient group and compared scores between groups to draw conclusions.
Results
The study found that those with anxiety and depression had higher CSI scores compared to those with neither condition. This meant that chronic cough patients with a diagnosis of anxiety and depression had reported more severe cough symptoms compared with patients with neither anxiety nor depression.
It is important to note that this link is only an association, not a causation. In other words, the study found a statistically significant relationship between anxiety and depression and chronic cough severity. However, it does not necessarily mean that anxiety and depression are the cause of more severe cough symptoms.
Study Significance
The results of the study may help inform physicians and help them develop a successful treatment plan for chronic cough that addresses mental health to improve overall patient quality of life.
