A hand-held trans-cranial magnetic stimulation device could be helpful in treatment of most severe migrane attacks, researchers say. When held against the back of the head and turned on, the device delivers two quick magnetic pulses into the brain, which scientists believe short-circuit the electrical storm.

Invented by Medtronic, the device was tested in a trial of 61 patients who experienced on average 15 or more headache days in a month and whose condition did not respond to conventional medicine for three months. The device is put up against the back of the head, and users push a button to administer the magnetic pulse
