Migraine Headache

What Causes Migraines

Until recently, the general theory on what causes migraines rested solely on the idea that abnormalities of blood vessel in the head were responsible for migraines. Now, however, experts tend to believe that migraine starts with an underlying central nervous system disorder, which, when triggered by various stimuli, sets off a chain of neurologic and biochemical events, some of which subsequently affect brain's vascular system.

There is a range of different kinds of headache, like cough headache, hypertension headache, constant headache, pregnancy headaches and alike. To cure headache, one should see a headache specialist and maintain a headache diary besides practicing relaxation techniques. It is usually the migraine patients who are most sensitive to light and in whom glaring lights might trigger headaches. Especially slow "flickering" lights rather than rapidly flickering ones cause a headache.

The conditions which put strain on the eyes can be working on computer or watching television for too long, playing video games, or reading in improper lighting conditions. But, apart from these, a poor posture, stress, and long periods of concentration are also some of the headache causes.
