Migraine

Overview

Migraine is a disorder that primarily affects one or both sides of the head and is characterized by severe and unprovoked headaches. It differs from a typical headache in that it comes with extra signs like nausea, vomiting, and sensitivity to light and sound. Although the precise cause of migraines is unknown, it is believed that transitory alterations in the brain's neurotransmitters, neurons, and blood vessels are to blame. Nearly half of all migraine sufferers also have a close family relative who has the disorder, which raises the possibility that genes may be involved. Hormonal changes, particular foods and drinks, stress, and exercise are triggers. One specific location may throb to varying degrees during a migraine headache. Others include nausea and sensitivity to light and sound. Medication for pain relief and prevention can help manage migraines.
