Transcutaneous stimulation of the cervical branch of the vagus nerve for cluster headache and migraine

6 Committee comments

6.1 The committee noted that migraine is a very common condition and therefore good evidence of efficacy is particularly important. This consideration contributed to the recommendation for further research.

6.2 The committee noted that cluster headache is a rare condition and that few effective treatment options exist for it.

6.3 The committee noted that the evidence for the efficacy of transcutaneous stimulation of the cervical branch of the vagus nerve for cluster headache was better than for migraine.

6.4 In its interpretation of the evidence, the committee noted the potential for a placebo response and the relapsing and remitting course of cluster headaches and migraine.

6.5 The committee noted that further evidence is likely to become available from a number of current trials.

6.6 The committee noted patient commentary and the number of positive comments received from patients during public consultation, much of which was favourable.
