Devices to Treat Migraine
A transcranial magnetic stimulation device, available by prescription, may be effective in patients with migraine with aura though not in patients with migraine without aura. It should not be used in patients with a history of epilepsy. It is hair dryer sized. A smaller device, developed by the same company, was approved in 2014 for acute treatment of migraine with aura. It is not yet widely available.
A Belgian company, Cefaly, makes a transcutaneous supraorbital neurostimulation headband (tSNS). It is designed to be a preventive treatment and to be used 20 minutes a day. About half of the patients respond. It may be helpful as a treatment for acute headache as well though this has not been tested fully.
