CONCLUSIONS: The present study proves that distinct subtypes of migraine with aura exist. [ncbi.nlm.nih.gov]

It further underlines the phenotypic differences between the different subtypes of migraine with aura which likely are caused by different etiological mechanisms. [ncbi.nlm.nih.gov]

BACKGROUND: To discover distinct underlying genetic and pathophysiological mechanisms it is crucial to drive clinical subdivision of migraine with aura as far as possible. [ncbi.nlm.nih.gov]
