Using MRI and voxel-based morphometry, the authors investigated 20 patients with chronic
tension type headache (CTTH) and 20 patients with medication-overuse headache and
compared them to 40 controls with no headache history. Only patients with CTTH
demonstrated a significant gray matter decrease in regions known to be involved in pain
processing. The finding implies that the alterations are specific to CTTH rather than a
response to chronic head pain or chronification per se.
