Clinical Insights

  • Visual auras typically develop gradually over 5+ minutes (unlike sudden stroke symptoms)
  • Most patients experience a mix of positive (bright lights, zigzags) and negative (blind spots) symptoms
  • The "fortification spectrum" - expanding C-shaped zigzag pattern - is pathognomonic for migraine
  • Symptoms often start in central vision and spread outward
  • Women are 4x more likely to experience migraine with aura than men (82% female in recent studies)
  • Visual aura can occur with or without subsequent headache
  • Nearly 90% of aura patients also experience migraine without aura
  • Aura typically begins in early twenties (average age 23.9 years)
  • About 1 in 8 patients may experience aura relapse within 24 hours
  • Post-attack fatigue affects 60% of patients, often lasting over 24 hours
  • Headaches following aura tend to be more intense than regular migraine attacks
