Trials of nonpharmacologic management have produced average reduction in migraines of 40%-50%, closely paralleling results obtained in trials of preventive drugs.
However, the evidence base for nonpharmacologic and pharmacologic prevention remains limited.
Biofeedback, cognitive-behavioral therapy, and relaxation therapy are frequently effective against migraine headaches and may be used adjunctively with pharmacologic treatments.
Occipital nerve stimulators may be helpful in patients whose headaches are refractory to other forms of treatment.
