Epidemiology and pathogenesis of posttraumatic headache

Area of Science:

• Neurology
• Traumatology

Background:

• Posttraumatic headache is a common consequence of head injuries.
• Definitions of mild head injury (MHI), mild traumatic brain injury (MTBI), and concussion are often confused.
• The pathophysiology of posttraumatic headache is not fully understood.

Purpose of the Study:

• To provide an overview of the epidemiology and pathophysiology of posttraumatic headache.
• To clarify definitions related to mild head injuries.
• To examine headache types, their pathophysiology, and potential contributing factors.

Main Methods:

• Literature review of epidemiology and pathophysiology.
• Analysis of definitions for MHI, MTBI, and concussion.
• Examination of headache types and their underlying mechanisms.
• Review of potential links between head/neck injuries and headache.
• Consideration of neurochemical changes, psychological, and legal factors.

Main Results:

• Headache is a frequent symptom after mild head trauma.
• Confusion exists regarding terminology like MHI, MTBI, and concussion.
• The exact pathophysiology of posttraumatic headache, similar to migraine, is often unknown.
• Potential links include head/neck trauma, neurochemical alterations, and psychological/legal influences.

Conclusions:

• Posttraumatic headache is a complex condition with multifactorial origins.
• Further research is needed to elucidate the precise pathophysiology.
• Understanding contributing factors is crucial for effective management.
