Headaches & Migraines

What is Headaches & Migraines?

Headaches are among the most common nervous system disorders, with a large share of adults experiencing at least one headache each year. Migraine affects more than 1 billion people worldwide and is a major contributor to neurologic disability. Modern pain science describes migraine as involving peripheral trigeminal nerve activation as well as central pain-processing changes, which helps explain why attacks can persist or recur even when triggers are not obvious.
