Study on brain abnormalities in migraines

“For the first time, we assessed cortical thickness and surface area abnormalities in patients with migraine, which are two components of cortical volume that provide different and complementary pieces of information,” said Massimo Filippi, M.D., director of the Neuroimaging Research Unit at the University Ospedale San Raffaele and professor of neurology at the University Vita-Salute’s San Raffaele Scientific Institute in Milan. “Indeed, cortical surface area increases dramatically during late fetal development as a consequence of cortical folding, while cortical thickness changes dynamically throughout the entire life span as a consequence of development and disease.”

The study used MRI to gain brain images from 63 migraineurs and 18 healthy controls. Using specialized software and statistical analysis, they estimated the cortical thickness and surface area and correlated it with the subjects clinical and radiological characteristics. </P

Compared to the control group, the migraineurs showed reduced cortical thickness and surface area in areas related to Pain Processing. Cortical thickness abnormalities were more pronounced and distributed than cortical thickness ones. There was the presence of aura and white matter hyperintensities-areas of high intensity on the MRIs that appeared to be more frequent in people with migraine- and was related to the regional distribution of cortical thickness and surface area abnormalities, and not to disease duration or attack frequency.

“The most important finding of our study was that cortical abnormalities that occur in patients with migraine are a result of the balance between an intrinsic predisposition, as suggested by cortical surface area modification, and disease-related processes, as indicated by cortical thickness abnormalities,” Dr. Filippi said. “Accurate measurements of cortical abnormalities could help characterize migraine patients better and improve understanding of the pathophysiological processes underlying the condition.”
Additional research is needed to fully understand the meaning of cortical abnormalities in the pain processing areas of migraine patients, according to Dr. Filippi. “Whether the abnormalities are a consequence of the repetition of migraine attacks or represent an anatomical signature that predisposes to the development of the disease is still debated,” he said. “In my opinion, they might contribute to make migraine patients more susceptible to pain and to an abnormal processing of painful conditions and stimuli.”MRI shows brain abnormalities in migraine patients

Add this to the brain abnormalities in FM and I must have a fascinating brain. Actually after one of my tests… CAT scan or MRI can’t recall my doctor told me I had a young looking brain because the surface of the brain ages over time and mine looked… young. Nice. Or is it just reduced cortical thickness due to massive amounts of migraines? Hmm. Who knows, but I doubt the brain likes being electrocuted that often… I imagine it would have some physiological change in the areas that process pain, just like it does in FM… which ironically makes us more wired for pain. https://w.atcontent.com/-/3PQ10uezYIU/nikki.albert/2fY7Z_sIe5-.text/Panel/Autocheck
