Secondary headaches can be due to trauma, vascular disorder, non-vascular intracranial disorder, substance abuse or withdrawal, infection, disturbances of homeostasis, disorders of facial structures, or psychiatric disorders.

Suspicion of secondary headaches requires cerebral imaging by computed tomography or magnetic resonance imaging.

Headache in secondary headaches results in most cases from changes in intracranial pressure, changes in vessel diameter, or irritation of the dura. The brain parenchyma is not pain sensitive.

Medication overuse is a frequent cause of the transition from episodic migraine or tension-type headache to chronic headache (>15 days/month).
