Migraine patients (Pts) show widespread structural and functional brain changes that are associated with symptoms and increased pain catastrophizing A, Migraine patients showed (i) increased gray matter volume (GMV) in the left (L) hippocampus and (ii) decreased cortical thickness in the L anterior midcingulate cortex (aMCC) compared to healthy control subjects. B, Pain catastrophizing correlated with GMV reductions in the (i) L primary somatosensory cortex (S1) and (ii) L medial prefrontal cortex (mPFC), and cortical thinning in the (iii) L dorsolateral prefrontal cortex (DLPFC) and middle temporal gyrus (MTG) in migraine patients. C, GMV reductions correlated with (i) disease duration (ii), attack frequency, and (iii) migraine pain intensity in patients. D, Whole-brain overlay maps for migraine patients and healthy controls for the (i) L PCC, (ii) L aINS, and (iii) aMCC seed regions rendered onto inflated …
