AAN 2026: GLP-1 Agonists Cut Migraine ED Visits 10%, Hospitalizations 14% vs Topiramate in 22,000-Patient Study
A presentation at the American Academy of Neurology 2026 meeting (closing April 22) reported that in 10,997 chronic migraine patients initiating GLP-1 agonists versus an equal topiramate cohort, GLP-1 users were 10% less likely to visit the ED (23.7% vs 26.4%), 14% less likely to be hospitalized, 42% less likely to start CGRP monoclonal antibodies, and 48% less likely to start valproate over 12 months — adding migraine to the growing list of GLP-1 secondary benefits.
