Aura Relapse 12.6% Within 24 hours, lasting ~85 minutes
Vertigo 12.5% During headache phase
Patient Demographics & Patterns
Also Have Migraine Without Aura 89.3%
Chronic Migraine (15+ days/month) 12.8%
Medication Overuse/Adaptation Headache 2.5%
Average Current Age 43.3 years
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
