Trigeminal cough, also known as a trigeminal-mediated cough, refers to a type of cough that is triggered by the stimulation of the trigeminal nerve. The trigeminal nerve is the fifth cranial nerve, responsible for sensory information and motor function in the face.
When the trigeminal nerve is irritated or stimulated, it can cause a reflexive cough response. This can be due to various factors, such as exposure to irritants, certain medications, or underlying inflammatory conditions affecting the nerve. Trigeminal cough is considered a form of a hypersensitive cough reflex.
The characteristic feature of trigeminal cough is the presence of a cough triggered by specific facial movements or touch. This means that coughing can be induced or worsened by activities like talking, eating, laughing, or touching certain areas of the face, particularly around the nose, mouth, or tongue.
Trigeminal cough is often different from other types of cough in that it may not respond well to conventional cough medications or treatments. Identifying and addressing the underlying cause, such as nerve irritation or inflammation, is crucial in managing this condition.
It is important to consult with a healthcare professional if you suspect you have trigeminal cough, as they can evaluate your symptoms, perform appropriate tests, and suggest the appropriate treatment options.
