Migraine visual aura, a common neurological symptom, is extensively studied but its link to subsequent headaches remains unproven. Vasospasm is a controversial factor in migraine pathophysiology, potentially affecting neurovisual function.

Area of Science:

  • Neurology
  • Ophthalmology
  • Neuroscience

Background:

  • Visual symptoms are common in diagnosing migraine patients.
  • Migraine with aura is the most frequent visual disorder studied.
  • The link between visual aura and subsequent cephalgia is not conclusively proven.

Purpose of the Study:

  • To review current understanding of visual symptoms in migraine.
  • To explore the pathophysiology of migraine-related visual disturbances.
  • To stimulate further research into this common neurological condition.

Main Methods:

  • Literature review of current research on migraine and visual symptoms.
  • Discussion of proposed mechanisms like spreading depression and vasospasm.
  • Synthesis of existing knowledge on neurovisual dysfunction in migraine.

Main Results:

  • The exact mechanism linking visual aura to cephalgia is still debated.
  • Spreading depression is a leading hypothesis for visual aura.
  • Vasospasm's role in complicated neurovisual dysfunction is controversial but possible.

Conclusions:

  • The pathophysiology of migraine with aura requires further investigation.
  • Understanding visual symptoms is crucial for neurologists and ophthalmologists.
  • Continued research is needed to clarify the complex relationship between visual phenomena and migraine headaches.
