Brain lesions in migraine

However, presence of any brain lesion is worrisome to most patients and according to some researchers may be indicative of small strokes or another type of brain damage. Some researchers have been concerned, although without any evidence, about possible accumulation of these lesions with progressive brain damage. A report in the June issue of Cephalalgia by Dr. Todd Rozen presents a case where a brain lesion seen on the first MRI scan was no longer seen on the second one 16 days later. We have always reassured our patients about the benign nature of these lesions, but it is good to have this additional evidence.
