1. Introduction: Migraine headaches , an overview

Migraine headaches are a common neurological disorder that affects millions of people worldwide. It is characterized by severe, throbbing          

headaches and sensitivity to light and sound. Migraines can be extremely debilitating, rendering individuals unable to carry out their daily activities and causing significant distress and discomfort.

What causes migraines?

The exact cause of migraines is not fully understood, but it is believed to involve a combination of genetic and environmental factors. It is thought that changes in brain chemicals and blood vessels in the brain play a role in the development of migraines. 

Serotonin, a neurotransmitter that regulates pain, is believed to be involved in the onset of migraines.

Migraines can be categorized into two main types: migraine without aura and migraine with aura. Migraine without aura is the most common type, accounting for about 80% of all migraines. It is characterized by a moderate to severe headache that can last between 4-72 hours. 

Migraine with aura, on the other hand, is characterized by a visual or sensory disturbance that usually lasts for about 20-60 minutes and is followed or preceded by a headache.
