CHANGES IN CEREBRAL BLOOD-FLOW VELOCITY ASSOCIATED WITH BIOFEEDBACK-ASSISTED RELAXATION TREATMENT OF MIGRAINE HEADACHES ARE SPECIFIC FOR THE MIDDLE CEREBRAL-ARTERY

Twenty-five patients with diagnosed migraine headaches were randomly a ssigned to a biofeedback-assisted relaxation therapy group or to a gro up who relaxed on their own. This study confirmed that the biofeedback trained group significantly decreased pain and medication more than t he self-relax group. The best responders were those with the more elev ated initial cerebral blood flow values and the changes in cerebral bl ood flow were specific for the middle cerebral artery.
