What is a migraine?
A migraine is a severe headache that 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. The reason for the drop in serotonin levels is not known.
Migraines can be triggered for various reasons, including stress, dehydration, lack of food and many other factors.
There is currently no cure for migraines, but the severity of an attack can be reduced and steps can be taken to prevent migraines from occurring.
Who is affected?
Although migraines are known to go unreported and undiagnosed, the condition is still more prevalent than diabetes, epilepsy and asthma combined. It is also one of the most common neurological conditions and affects around one in seven people.
It is estimated that there are over 190,000 migraine attacks every day in the UK.
Migraines are more prevalent amongst women affecting approximately one in four women and one in 12 men in the UK.
