Migraine Symptoms: Stages, Triggers, Frequency & Prevention

Migraine is classified as a neurological disorder and is characterized by pounding pain or a pulsing sensation on one portion of the skull. It is commonly accompanied by nausea, vomiting, and hypersensitivity to light and sound. Migraine attacks can last for days or hours, and the discomfort can be tough to deal with daily activities. Sometimes, a warning sensation known as an aura appears before or together with the headache. Auras can cause visual anomalies such as sparkles of light or blind spots and bodily symptoms such as itching on one side of the face, hand, or foot, and difficulty speaking. Certain headache drugs can help avoid migraines making them less painful.

Causes of Migraine

[Click Here for Sample Questions]

Headaches are a sign of migraine illness. Researchers don't know what causes migraine, but they appear to be linked to alterations in your brain and DNA. Migraine factors such as tiredness, harsh lights, or changing weather might be passed down from parents to children.

For several years, experts believed that alterations caused migraines in the blood supply in the brain. Most people now believe that while this can add to the discomfort, that is not its cause.

A migraine is considered to start when overactive neurons send out messages that trigger your trigeminal nerve, which gives you sensation in your face and head. This causes your body to create serotonin and calcitonin gene-related peptides (CGRP). CGRP makes the blood vessels in the membrane of the brain dilate. Neurotransmitters then cause inflammation and pain.
