There are few treatments available for the millions of people who suffer from migraines. New early-stage research offers new hope.
Studies presented Tuesday at the American Academy of Neurology's annual meeting suggest that two new drugs may prevent migraines from happening.
"We've identified a new preventive treatment for migraines, something that reduces frequency, the number of attacks and severity of attacks, how bad the attacks are," said Dr. Peter Goadsby, co-author of both studies and professor of neurology at Kings College, London and the University of California, San Francisco. "The results herald a new mechanism for the preventive treatment of migraines."

Some 37 million Americans suffer from migraines, those incredibly painful and often debilitating headaches. While they've been known to knock a person out, migraines weren't thought to permanently affect the brain - until now. A new study published Wednesday in the journal Neurology suggests migraines may indeed leave a mark.
"Our review and meta-analysis study suggests that the disorder may permanently alter brain structure in multiple ways," said study author Dr. Messoud Ashina, a neurologist at the University of Copenhagen in Denmark.
A migraine is a common type of headache where throbbing pain is typically felt on just one side of the head. Sufferers experience sensitivity to light, nausea and vomiting. Women are three times more likely to be affected by migraines than men.

The U.S. Food and Drug Administration is warning pregnant women to stay away from migraine medicine containing valproate. The agency says the drug can lead to decreased IQ scores in children whose mothers took the medication during pregnancy.
Valproate sodium (Depacon), valproic acid (Depakene and Stavzor), and divalproex sodium (Depakote, Depakote CP and Depakote ER) are among the valproate products the FDA says pregnant women should never use. That includes their generic versions.

Just a few days after new migraine treatment guidelines were released at the American Academy of Neurology's annual convention, new research published in this week's edition of JAMA, finds Botox may not work as well on migraines as originally thought.
The AAN's recommendations found that numerous drugs, such as the seizure drugs divalproex sodium, sodium valproate and topiramate, along with the beta-blockers metoprolol, propranolol and timolol, are effective for migraine prevention.
The guidelines also noted herbal drugs such as petasites relieved migraine pain and nonsterodial anti-inflammatory drugs, such as ibuprofen and naproxen sodium should be offered to people with migraines to reduce the frequency and severity of attacks.
Botulinum toxin A, otherwise known as Botox, was not mentioned.
