Migraine and tension-type headaches may share a common pathophysiology, suggesting a single evolving process. This convergence hypothesis could improve early headache recognition and treatment.

Area of Science:

  • Neurology
  • Headache Medicine
  • Pathophysiology

Background:

  • Historically, migraine and tension-type headaches (TTH) have been differentiated.
  • Similarities between these primary headache types suggest a shared underlying pathophysiology.

Purpose of the Study:

  • To propose a convergence hypothesis for primary headaches.
  • To link clinical headache features with pathophysiological models.
  • To explore implications for diagnosis and treatment.

Main Methods:

  • Review of historical differentiation between headache types.
  • Synthesis of clinical features with current pathophysiological models.
  • Hypothesizing an escalating pathophysiological process.

Main Results:

  • Similarities between migraine and TTH outweigh differences.
  • A convergence hypothesis suggests headaches evolve through stages.
  • Premonitory symptoms may initiate a process leading to TTH and potentially migraine.

Conclusions:

  • Migraine and TTH likely share a common pathophysiological origin.
  • The convergence hypothesis explains the spectrum of primary headache disorders.
  • This model offers potential for earlier diagnosis and targeted treatment of headaches.
