BACKGROUND The pathophysiology of chronic migraine (CM) is not fully understood. We aimed to examine transcranial magnetic stimulation (TMS) indices of cortical excitability in patients with CM and also performed PET studies to ascertain if there were any areas of activation and inhibition for possible correlation. METHODS Excitability of the cortex was assessed by a reliable parameter of magnetic suppression of perceptual accuracy (MSPA) profiles using transcranial magnetic stimulation in 25… CONTINUE READING
