Luis Mejico, MD, provides an overview of migraine headaches, starting with how they are diagnosed, and their symptoms, which can be debilitating for some sufferers. Mejico, a professor of neurology and ophthalmology at Upstate, also goes over the common triggers as well as the three types of treatment. He says some behavioral modifications prove helpful. Also, some medications are used as preventives, to lessen the frequency or severity of migraines, while other medications (as well as some vitamins and minerals) are prescribed for use during a migraine headache.
