Posttraumatic Headache

Area of Science:

• Neurology
• Neuroscience
• Public Health

Background:

• Posttraumatic headache (PTH) is the most frequent secondary headache disorder.
• It is a common and potentially debilitating symptom following concussion (mild traumatic brain injury).
• Increased public awareness of traumatic brain injury has spurred more research into PTH.

Purpose of the Study:

• To review the current understanding of posttraumatic headache.
• To highlight the need for further research into its pathophysiology and treatment.
• To emphasize the diagnostic criteria and current treatment approaches for PTH.

Main Methods:

• Literature review of existing studies on posttraumatic headache.
• Analysis of diagnostic criteria and temporal relationship to head injury.
• Examination of current treatment strategies based on primary headache phenotypes.

Main Results:

• PTH is the most common secondary headache, affecting approximately 4% of headache disorder cases.
• Diagnosis relies on the temporal link to a head injury and often mimics primary headache types.
• No specific treatments are currently approved for PTH; existing therapies are repurposed.

Conclusions:

• The pathophysiology of PTH is not well understood and likely multifactorial.
• Further research is essential to refine PTH definition, elucidate mechanisms, and develop targeted treatments.
• Current management involves applying treatments used for other headache disorders.
