A wide range of diseases can present to the ED with headache as the major or only symptom. Infectious diseases, inflammatory diseases, autoimmune diseases, and malignancy can cause headache. Processes that raise or lower intracranial pressure can also result in headache. In this chapter, we discuss the epidemiology, pathophysiology, diagnosis, and treatment of other secondary headaches including brain tumor headache, post-traumatic headache, high- and low-pressure headache, cervicogenic headache, trigeminal neuralgia, and headaches attributed to infection, Chiari malformation, arteritis, disorders of the eye, substances or withdrawal headache, and autonomic dysreflexia. In this chapter we also discuss primary (idiopathic) stabbing headache.
