Migraine is the most common neurological condition. It affects approximately one in four women and one in 12 men in the UK.

A migraine is a severe headache which may be accompanied by nausea and increased sensitivity to light and sound. It is generally thought they are caused by a drop in the level of serotonin in the brain, causing a widening in the blood vessels, but the reason for the drop in serotonin levels is not well understood.

Migraines can be triggered for various reasons, including stress, dehydration, lack of food and many other factors. There is currently no cure for migraine, but the severity of an attack can be reduced and steps can be taken to prevent migraines from occurring.
