A migraine is a headache. Most headaches are acute, meaning they are sharp and sudden, but they will go away. Migraines are chronic. The pain may go away but it will come back later on.

I get migraines sometimes, and I get headaches very often. Migraines are *far* worse than headaches.

I don't think psychology actually has much to do with migraines and headaches, aside from overwhelming stress and stuff that may cause it, but on itself it's still a physical occurrence highly related to the brain and whatever factors that give them shape, and on a physical level. Other then migraines being much worse then a headache and a valid reason to seek medical attention and treatment for, not sure what intricacies separate the two though.

A migraine is a specific type of headache characterized by severe pain lasting several hours or more, often accompanied by nausea, vomiting, and vision issues.

"Headache" is actually a SYMPTOM of Migraine. Other symptoms include photo- and phonophobia, nausea, vomiting, possibly diarrhea... before a migraine one might see lights brightly, or smell a certain smell that isn't actually there. Migraines can be triggered by anything from smoke inhalation to menstrual cycles to perfumes to dehydration.

Undetermined, shown on Functional MRI, read below. Abnormalities with white matter of the Brain. T2-weighted magnetic resonance imaging, Brain changes = Physiological difference. Magnetic Resonance Imaging in Migraine and Tension-Type Headache Cerebral magnetic resonance imaging was performed on 63 patients with chronic primary headache (28 with migraine with and without aura, 35 with tension-type headache). Fifty-four headache-free individuals of the same age range were used as controls. The headache sufferers showed an incidence of focal white matter abnormalities on T2-weighted magnetic resonance imaging significantly higher than the age-matched control group (33.3% vs 7.4%). The incidence of white matter abnormalities did not correlate with age (except for patients older than 60 years), sex, headache history, headache status, or ergotamine consumption. Migraine (with and without aura) and tension-type headache patients had similar prevalence of white matter abnormalities (32.1% vs 34.3%). The lesions were predominantly distributed in the frontal region, independent of the side of usual aura or headache. Our findings indicate that both migraine and tension-type headache may be associated with early pathologic changes in the brain and may share, at least in part, common pathogenic pathways.

Thank you Sinister, I worked in Diagnostic Imaging for about 8 years and I thought the F MRI would show different brain activity if there was an organic difference.
