Neuroimaging Studies of Chronic Primary Headaches Using Positron Emission Tomography and Magnetic Resonance Imaging
In Brief
An observational study for Migraine and Chronic Migraine. Completed, enrolled 78 participants across 1 site.
Detailed Summary
Investigators hypothesize that chronic primary headaches are accompanied by a discrete pattern of brain metabolism and activity involving brain structures related to the development of acute exacerbations as well as pain modulation. Such structures include the brainstem, hypothalamus, and orbitofrontal cortex and can be defined using functional brain imaging.
