What Causes Migraine?

Wondering what exactly happens in your head when you suffer from Migraine? Well, this is exactly what happens; Migraine is actually an ailment of the nervous system. It happens when there is a contraction of the blood vessels that are responsible for servicing the brain.

These blood vessels stay tightly constricted as they perform their very essential duty of supplying blood to the brain. However, due to some triggers and factors, the blood vessels may ‘burst open’ and cause blood to gush out and flow to the brain and causes a severe one-sided headache which is known as Migraine.

Types of Migraine

There are different types of migraine, some are very mild and barely noticeable, while other types are very strong and severe and may even cause temporary blindness or paralysis. Some common types of Migraine include:

The two types of Hemiplegic Migraines include:

  • Familial Hemiplegic Migraine: This is usually caused by a genetic disorder and is passed on from one family member to another.
  • Sporadic Hemiplegic Migraine: This type of hemiplegic migraine has absolutely nothing to do with genetics but is just as terrible as the familial hemiplegic migraine. It also presents the same symptoms.

2. Ophthalmic Migraine: The Ophthalmic Migraine is sometimes called Retinal or Ocular migraine. It causes severe visual disturbances and blind spots, which usually lasts for between one minute and one hour before the migraine starts. Ophthalmic migraine may also cause temporary blindness.
