What are the Causes of Migraine & Factors which makes you prone to have one?

It is observed that genetics and environmental factors play a role in causing migraines. Functions of certain chemicals in the brain may also be responsible. With the levels of a chemical known as serotonin decreasing during migraine attacks, the trigeminal nerve releases a chemical substance called neuropeptides, which travels to the brain's outer covering. The result is migraine pain.

Several factors make you more prone to having migraines, namely:

• Family history

  - If the patient has a family member with migraines, then they have increased chances of developing a migraine.

• Age

  - Migraines can begin at any age, but the attack usually starts in adolescence. They may become intense during the age of 30 and above, and gradually becoming less severe and less frequent in the 40s.

• Sex

  - Women are three times more likely to have migraines. Although headaches tend to affect boys more than girls during childhood, at the time of puberty and beyond, more girls are affected.

• Pregnancy

  - Some women report that migraine attacks begin during pregnancy, or their attacks have increased during pregnancy.
