Does the vagus nerve affect coughing?
Table of Contents
In patients with neurogenic chronic cough, peripheral laryngopharyngeal hypersensitivity of the vagus nerve stimulates the cough reflex. We present three cases of “Oto-tricho-tussia,” describing hair within the ear canal stimulating Arnold’s branch of the vagus nerve and triggering the urge-to-cough.
Can the vagus nerve cause chronic cough?
Similarly, injury to various branches of the vagus nerve have been described as potential causes of unexplained chronic cough. Patients with these conditions frequently describe symptoms that suggest sensitization of the cough reflex and a neuropathic response.
How do you get rid of a neurogenic cough?
Treatment for neurogenic cough is aimed at symptom control. Tricyclic antidepressants, gabapentin, and pregabalin have demonstrated efficacy and are considered first-line medications, but optimal dose, length of treatment, time to maximum benefit, and relapse rates after drug cessation are unknown.
Why does vagus nerve cause cough?
Cough originates from stimulation of structures innervated by the vagus nerve, including the airways and distal esophagus. Arnold nerve reflex describes the induction of cough by stimulation of the external auditory canal, which is innervated by the auricular branch of the vagus.
What nerve causes you to cough?
The cough reflex starts with stimulation of irritant receptors with afferents in the vagus nerve (cranial nerve X).
Can nerve damage make you cough?
Chronic cough is a neuropathic condition that could be secondary to sensory nerve damage caused by inflammatory, infective and allergic factors. Recent success in the treatment of chronic cough with agents used for treating neuropathic pain such as gabapentin and amitryptiline would also support this concept.
What nerve makes you cough?
What stimulates cough reflex?
The cough reflex is initiated by activation of bronchopulmonary C-fibers and the mechanically-sensitive cough receptors. Stimuli initiating cough through activation of one or both of these vagal afferent nerves include capsaicin, acid, bradykinin, cinnamaldehyde, cigarette smoke and non-isotonic aerosols.
What triggers coughing reflex?
The cough reflex can be triggered by food particles you accidentally inhale, air pollution, and airborne allergens like pollen. People with COPD and asthma often cough during flare-ups when their airways tighten due to inflammation. Coughing is also a common symptom of respiratory tract infections.
Can nerve damage cause chronic cough?
How you can repair your vagus nerves?

What are the common signs of vagus nerve problems?

What is the vagus nerve, what does it do?
The vagus nerve is the longest nerve of the autonomic nervous system and is one of the most important nerves in the body. The vagus nerve helps to regulate many critical aspects of human physiology, including the heart rate, blood pressure, sweating, digestion, and even speaking.
What kind of Doctor treats vagus nerve disorders?
Before the procedure. Before surgery,your doctor will do a physical examination.
