Preventive Treatment for Episodic Migraine.

Episodic migraine is a debilitating condition. Preventive therapy is used to reduce frequency, duration, or severity of attacks. This review discusses principles of preventive treatment with a focus on preventive treatment options for people with episodic migraine. Specifically discussed is evidence and use of new migraine-specific treatment options for episodic migraine, such as calcitonin gene-related peptide monoclonal antibodies, a noninvasive transcutaneous electrical nerve stimulation device, and a single-pulse transcranial magnetic stimulator device. Also discussed are evidence-based updates from the 2012 American Academy of Neurology and the American Headache Society guidelines regarding major medication classes recommended for preventive episodic migraine treatment.
