Summary
Higher cortical function disorders during migraine aura are more common than previously believed, affecting 65% of patients. Longer aura duration is linked to an increased frequency of these neurological symptoms.
Area of Science:
- Neurology
- Neuroscience
- Migraine Research
Background:
- Migraine aura affects 20-30% of patients, often presenting with visual and sensory symptoms.
- Some aura descriptions suggest involvement of broader cortical areas beyond typical symptoms.
Purpose of the Study:
- To prospectively evaluate the frequency and types of higher cortical function (HCF) disorders during visual and/or sensory migraine aura.
Main Methods:
- Interviewed 60 patients with visual/sensory aura regarding HCF disorders (praxia, gnosia, memory, speech).
- Compared patients with and without HCF disorders based on demographics and aura characteristics.
Main Results:
- 65% of patients reported at least one HCF disorder during aura.
- HCF disorders were associated with longer aura duration (28.5 vs. 19.8 minutes).
- Motor dysphasia (82%) and dysnomia (31%) were the most frequent HCF disorders; motor dysphasia was more common in combined visual and sensory aura.
Conclusions:
- Higher cortical function disorders during migraine aura are more prevalent than previously recognized.
- Aura duration significantly influences the occurrence of HCF disorders.
