An electronic device that effectively wards away migraine pain before it starts has been developed by researchers at the Ohio State University Medical Center.

The results are based on a study, which showed that the experimental device is safe and effective in eliminating headaches when administered during the onset of the migraine.

Dr. Yousef Mohammad, a neurologist and principal investigator of the study at Ohio State's Medical Center, said that the results are promising given that only 50 to 60 percent of migraine patients respond to traditional migraine drug treatments.

The noninvasive transcranial magnetic stimulator (TMS) device interrupts the aura phase of the migraine, often described as electrical storms in the brain, before they lead to headaches.

Migraine sufferers often describe 'seeing' showers of shooting stars, zigzagging lines and flashing lights, and experiencing loss of vision, weakness, tingling or confusion, followed by intense throbbing head pain, nausea and vomiting.

Previous studies, conducted at Ohio State, using a heavy and bulky TMS device, reduced headache pain. To expedite treatment at home, a portable hand-held device was developed and tested.

"Stimulation with magnetic pulses from the portable TMS device proved effective for the migraine patients. Because of the lack of adverse events in this trial and the established safety of the TMS device, this is a promising treatment for migraines with aura. This sets the stage for future studies in migraines without aura," Mohammad said.
