Observational Study
Asthma is a risk factor for new onset chronic migraine: Results from the American migraine prevalence and prevention study.
To test the hypothesis that in persons with episodic migraine (EM), asthma is a risk factor for the onset of chronic migraine (CM). ⋯ Asthma is associated with an increased risk of new onset CM 1 year later among individuals with EM, with the highest risk being among those with the greatest number of respiratory symptoms. The exact mechanisms underlying this association are unknown, but could suggest mast cell degranulation, autonomic dysfunction, or shared genetic or environmental factors.

Randomized Controlled Trial
Memantine for Prophylactic Treatment of Migraine Without Aura: A Randomized Double-Blind Placebo-Controlled Study.
Uncontrolled studies in human have suggested that memantine might be a suitable option for migraine prophylaxis. ⋯ Memantine might be a tolerable and efficacious option for prophylaxis in patients with migraine without aura. Tolerability, short duration required for titration, and safety profile in pregnancy might give memantine an advantage over other antimigraine medications. The study was registered in the Iranian Registry of Clinical Trials (Registration number: IRCT2013120115616N1).

The vagus nerve (VN), the "great wondering protector" of the body, comprises an intricate neuro-endocrine-immune network that maintains homeostasis. With reciprocal neural connections to multiple brain regions, the VN serves as a control center that integrates interoceptive information and responds with appropriate adaptive modulatory feedbacks. While most VN fibers are unmyelinated C-fibers from the visceral organs, myelinated A- and B-fiber play an important role in somatic sensory, motor, and parasympathetic innervation. ⋯ VN has four vagal nuclei that provide critical controls to the cardiovascular, respiratory, and alimentary systems. Latest studies revealed that VN is also involved in inflammation, mood, and pain regulation, all of which can be potentially modulated by vagus nerve stimulation (VNS). With a broad vagal neural network, VNS may exert a neuromodulatory effect to activate certain innate "protective" pathways for restoring health.

Case Reports
Movement Disorders From the Use of Metoclopramide and Other Antiemetics in the Treatment of Migraine.
Nausea and vomiting are a frequent accompaniment of migraine and anti-nausea medications are frequently used in its management. The majority of anti-nausea medications that are used in migraine are dopamine receptor blocking agents and therefore have the potential to cause drug-induced movement disorders. This article explores the risk of such drug-induced movement disorders in migraineurs who were treated with these medications.

To provide an overview of the clinical course for children and adolescents with migraine variants (M.V.), childhood periodic syndromes or the episodic syndromes that may be associated with migraine using the International Classification of Headache Disorders, 3rd Edition Beta version [ICHD-3] International Headache Society criteria for the diagnosis of each disorder. ⋯ The episodic syndromes that may be associated with migraine or migraine variant is multilayered neurological disorder in young children and adolescents. Within the these generally pediatric syndromes there are associated disorders described in this review, to provide a clinical overview and including the less common forms of migraine, such as acute confusional migraine, trauma-triggered migraine, and transient global amnesia.
