New research has suggested that technology-based, non-invasive and drug-free techniques may be effective at relieving pain for some migraine sufferers, according to a study presented at the annual American Headache Society meeting in Boston. The treatment used in clinical trials conducted by Dr. Richard B. Lipton, a researcher in the cause and treatment of migraines, utilized a portable transcranial magnetic stimulation device to treat patients suffering from migraines with auras, perceptual disturbances that warn of oncoming episodes in some sufferers.
