Botox injected in head cuts migraine frequencyPublished On: Thu, May 12th, 2011 | Neurobiology | By BioNews
Spanish researchers have confirmed that botox treatment can reduce the number of migraines experienced by many sufferers.
University of Granada scientists said that injecting a local anesthetic or botulinum toxin (botox) into certain points named ‘trigger points’ of the pericraneal and neck muscles reduce migraine frequency among migraine sufferers.
They have identified the location of these trigger points –whose activation results in migraine– and their relationship with the duration and severity of this condition.
Juan Miguel García Leiva –a researcher at the University of Granada Institute for Neuroscience “Federico Oloriz” – specified that this treatment “is not a first-choice treatment for migraine sufferers, but it can only be applied in patients with chronic migraine who have tried several treatments with poor results, and who show peripheral sensitization of muscles.
