Repurposing Botulinum Toxin as Treatment for Chronic Migraines

14 million Americans suffer migraine headaches every day. Many go untreated and many who are treated continue to have headaches. But an old drug proved to offer a new way to treat migraines, with the FDA approval of botulinum toxin injections for severe chronic migraine. Dr. David Simpson, professor of neurology at Mount Sinai School of Medicine in New York City and director of the clinical neurophysiology lab at Mount Sinai Hospital, joins host Dr. Anthony Alessi to discuss what patients qualify for this treatment, problems and risks associated with taking the injections, and the controversial results of the earlier clinical trials for this treatment.
