Headache after trauma: physiological considerations.

Posttraumatic headache (PTH) is one of the most controversial disorders in secondary headaches. It is the most common symptom of postconcussion syndrome. There are many unresolved issues around PTH despite the efforts by the International Headache Society to classify and clarify this entity. This article reviews the classification, pathophysiology, and treatment of PTH, as well as best management of patients with psychiatric comorbidities. Due to the complexity of PTH, the different forms of appearance, its pathophysiology, and the implications of psychological factors, a multidisciplinary team to cover all aspects appears as the best way to approach management and treatment.
