Patients treated with four weeks of transcranial electrical stimulation (tDCS) found relief from their chronic migraine headaches unresponsive to typical therapies. In this study the motor cortex was stimulated. High current was able to be safely and effectively to deep brain structures.
Researchers from the university of Michigan, Harvard and the city college of the city of New York employed tDCS on 13 patients as preventative therapy resulting in a 37% reduction in head pain in the treated individuals.
A positive response was seen at four weeks but repeated treatments were needed for a lasting effect.
