A new study has shown that peripheral nerve stimulation (PNS) of the occipital nerves effectively alleviates chronic migraine over 1 year. PNS provided good or excellent headache relief in patients with pharmacologically intractable chronic migraine, although the high rate of adverse events remains a concern: 70% of the 157 patients experienced at least one adverse event, and almost half of these events required surgical intervention or hospitalization.
