Does a cough have anything to do with a concusion?

Cough and concussion: It depends on what you're asking. If you are asking if coughing is a symptom of a concussion, the answer is that this is very unlikely. Although some believe that a cough may cause a concussion, this is also very unlikely. At times a cough certainly can hurt or give you a headache, but a concussion is caused by trauma to your head resulting in injury or a "bruise" of you brain.
