Benign cough headache.

Abstract

Benign cough headache is an uncommon primary headache disorder marked by short-lasting attacks of pain triggered by coughing. Magnetic resonance imaging of the brain is required to assure that the cough headache is truly benign. The aetiology of the pain is unclear, but is probably associated with the brief increased intracranial pressure that attends coughing. We have reviewed the clinical features, aetiology, differential diagnosis, management, and prognosis of benign cough headache.
