Hi SMARAJIT DAS,    Anyone who has three or more Migraines a month needs to be talking with their doctor about prevention. There's growing evidence that Migraine is a progressive brain disease. A recent study showed that Migraines can cause brain damage, and that people with three or more Migraines a month are more susceptible to this damage. For more information, see Is Migraine a Progressive Brain Disease? and Yes, Migraines Can Cause Brain Damage.   But don't give up hope because there are more than 100 medications available to treat Migraine disease. I know how easy it is to feel as if you've tried everything out there, but there are so many medications that can be used for Migraine and headache prevention that it's literally impossible. You can find a list of potential Migraine and headache preventives in Migraine preventive medications - too many options to give up! If your doctor isn't able to help you, it may well be time to consult a Migraine and headache specialist. It's important to note that neurologists aren't necessarily Migraine and headache specialists. Take a look at the article Migraine and Headache Specialists - What's So Special?
