Can the vagus nerve cause cough?

Yes, the vagus nerve can contribute to coughing. It plays a role in the reflex pathways that control the cough reflex, which is activated in response to irritants or inflammation in the airways. Stimulation of the vagus nerve can lead to sensations that trigger coughing, especially if the respiratory tract is affected. Additionally, certain medical conditions that involve the vagus nerve may also result in a cough.
