Migraine may cause permanent change in brain structure
WASHINGTON, District of Columbia (AFP) - Migraines may cause permanent changes in brain structure, though just how this affects patients over the long-term is unknown, according to research out Wednesday.
A meta-analysis performed on six population-based studies and 13 clinic-based studies was published in Neurology, a journal of the American Academy of Neurology.
The review found that people with migraines faced a higher risk of brain lesions, white matter abnormalities and altered brain volume than people without migraines.
"Traditionally, migraine has been considered a benign disorder without long-term consequences for the brain," said study author Messoud Ashina, with the University of Copenhagen in Denmark.
