A US study has found that the cortex area of the brain is thicker in people who have migraines compared to those who do not. The researchers do not know whether the difference causes the migraine or having migraine over the years has led to the difference in brain structure.
The study is published in the 20th November online issue of the journal
Neurology and is the work of Dr Nouchine Hadjikhani, of The Martinos Center for Biomedical Imaging at Massachusetts General Hospital in Charlestown, Massachusetts, and colleagues.
