Abstract
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.Entities:
