White matter lesions (WML) are more common in people who suffer from migraine headaches with or without aura and my recent post mentioned yet another study confirming this finding. Researchers from Johns Hopkins School of Medicine just published a study in the journal Neurology which provides further reassurance about the benign nature of these mysterious lesions. They examined over 1,000 migraine sufferers with two MRI scans separated by 8 to 12 years. While those with migraines had a significantly greater risk of having these WML or as these researchers called them white matter hyperintensities (WMH) the number of these lesions did not increase with the passage of time. This study contradicts a larger, so called CAMERA study which showed progression of the number of WMLs in women. That study was done in younger people and the authors speculate that whatever might be causing these WML may be occurring at a younger age when the disease of migraine is most active. It is a well established fact that migraines are most common in 20s, 30s, and 40s but then tend to subside.
