Chronic post-traumatic headache (PTH) always arises from some sort of head injury such as mild traumatic brain injury or concussion. The terminology and definitions for these injuries remain controversial and continue to evolve. This article reviews and updates current terminology and definitions for these head injuries, along with current concepts of pathophysiology. The second portion of this article considers the persistence of the other symptoms associated with chronic PTH, which constitute the post-concussive disorder. PTH is the most common symptom after a head injury, but post-concussive symptoms often complicate the clinical picture and must be considered in the overall management of the chronic PTH patient.

Chronic post-traumatic headache (CPTHA), the most frequent complaint after traumatic brain injury (TBI), dramatically affects quality of life and function. Despite its high prevalence and persistence, the mechanism of CPTHA is poorly understood. This literature review aimed to analyze the results of studies assessing the characteristics and sensory profile of CPTHA in order to shed light on its possible underlying mechanisms. The search for English language articles published between 1960 and 2013 was conducted in MEDLINE, CINAHL, and PubMed. Studies assessing clinical features of headache after TBI as well as studies conducting quantitative somatosensory testing (QST) in individuals with CPTHA and in individuals suffering from other types of pain were included. Studies on animal models of pain following damage to peripheral tissues and to the peripheral and central nervous system were also included. The clinical features of CPTHA resembled those of primary headache, especially tension-type and migraine headache. Positive and negative signs were prevalent among individuals with CPTHA, in both the head and in other body regions, suggesting the presence of local (cranial) mechanical hypersensitivity, together with generalized thermal hypoesthesia and hypoalgesia. Evidence of dysfunctional pain modulation was also observed. Chronic post-traumatic headache can result from damage to intra- and pericranial tissues that caused chronic sensitization of these tissues. Alternatively, although not mutually exclusive, CPTHA might possibly be a form of central pain due to damage to brain structures involved in pain processing. These, other possibilities, as well as risk factors for CPTHA are discussed at length.

Chronic post-traumatic headache (PTH) is one of the most common complaints after mild traumatic brain injury, yet evidence to date is insufficient to direct conventional treatment of headaches with this etiology. Therefore, the current guidelines recommend a symptomatic approach for the three patterns of PTHs: migraine-like, tension-like, and mixed symptomatology. To improve response rates and minimize the potential for polypharmacy, adverse effects, and risk of dependency, effective nonpharmacologic options should be employed to support faster and safer patient rehabilitation. Current evidence shows that acupuncture is at least as effective as drug therapy for migraine prophylaxis and neurovascular and tension-type headaches. Because of its safety, cost-effectiveness, and long-lasting benefits, adjunctive acupuncture should be offered to patients with chronic PTHs and may be a valuable primary treatment alternative for those with contraindications to pharmacotherapy. Future head-to-head, adequately powered, well-controlled randomized clinical trials are needed to investigate acupuncture efficacy for PTHs.
