Migraine headaches sometimes preceded by warning symptoms and can have specific triggers but can vary in severity and type.
The classic migraine is on one side of the head with the vision effected. Migraine is a common headache disorder with no conclusive cures, of many types affecting about 15 per cent of the population.
In cases of recent onset cases, increasing severity/frequency, neurological symptoms of pins and needles and visual field defects all indicate further work up is indicated eg MRI with a neurologist or neuro-ophthalmologist
Migraine can be triggered by many factors such as food, medication,weather, stress, lack of sleep, skipping meals, dehydration. Triggers need to be kept in a diary,ideally.
Visual symptoms such as blurred vision, visual aura and photophobia can occur during migraine attacks, but not necessarily always.
Less than half of current migraine sufferers have been formally diagnosed and about one-third are thought to receive appropriate treatment with prescription medications.
Colorimeter research data determines certain specific tints can help migraine sufferers whose migraines are triggered by pattern glare. Pattern glare tests involve tints (that later can be prescribed) often but not always blue or yellow to reduce the nausea that can arise from stripe patterns for some people by reducing or changing the contrast between black and white.
The theory is some people have an hyperactivity imbalance between their central and peripheral vision for light, flicker and certain spatial frequencies in stripes and patterns and can make reading difficult
Migraine is a complex and the most common neurological condition and classified by the World Health Organisation as the 7th most disabling disease worldwide, the 4th for women. It is three times more common in women than it is in men and is usually inherited. It is a very individual condition. Some people experience only an odd attacks while others suffer on a regular basis.
