Recent research is showing that a non-systemic treatment can provide relief from migraine headaches, which affect an estimated 12% of Americans. Dr. Teshamae Monteith is an associate professor of clinical neurology and chief of the headache division at the University of Miami Health System. Monteith said a study involving adolescents found that an app-controlled neuromodulation device not only eased migraines but could also prevent them. Monteith said medication overuse can actually lead to more headaches, which is why alternatives are important. Researchers found that consistent use of the device may also reduce the number of overall migraine episodes.
