Botox Useful For Preventing Frequent Migraines

Botulinum toxin A (Botox) injections can help prevent migraines in patients who have headaches almost every day, according to study results reported Thursday at the annual meeting of the American Headache Society in Philadelphia. "Our study focused on migraine patients with chronic daily headache, which is defined as having a headache at least 15 days per month," lead author Dr. David W. Dodick, from the Mayo Clinic in Scottsdale, Arizona, told Reuters Health. "These patients represent a minority of all migraine sufferers, but they account for at least 50 percent of the patients seen in specialty headache clinics."
