Review Meta Analysis
The efficacy of transcranial magnetic stimulation on migraine: a meta-analysis of randomized controlled trails.
As a non-invasive therapy, whether transcranial magnetic stimulation (TMS) is effective on migraine. This article was aimed to assess the efficacy of TMS on migraine based on randomized controlled trails (RCTs). ⋯ TMS is effective for migraine based on the studies included in the article.

We have genotyped a Swedish cluster headache case-control population for three genetic variants representing the most significant markers identified in a recently published genome wide association study on cluster headache. The genetic variants were two common polymorphisms; rs12668955 in ADCYAP1R1 (adenylate cyclase activating polypeptide 1 receptor type 1), rs1006417, an intergenic variant on chromosome 14q21 and one rare mutation, rs147564881, in MME (membrane metalloendopeptidase). ⋯ In conclusion rs12668955 and rs1006417 do not impact the risk of developing cluster headache in the Swedish population. Also, rs147564881 does not seem to be enriched within the Swedish cluster headache patient group.

Headache attributed to airplane travel, also named "airplane headache" (AH) is a headache that occurs during take-off and landing. Today, there are still uncertainties about the pathophysiology and treatment of AH. This systematic review was performed to facilitate identification of the existing literature on AH in order to discuss the current evidence and areas that remain to be investigated in AH. ⋯ Based on this systematic review, further studies seem required to investigate underlying mechanisms in AH and also to investigate the biological effects of nonsteroidal anti-inflammatory drugs and triptans for alleviating of AH. These studies would advance our understanding of AH pathogenesis and potential use of treatments that are not yet established.

Excessive daytime sleepiness (EDS, defined as Epworth sleepiness scale score > 10) is a common symptom, with a prevalence of 10-20% in the general population. It is associated with headache and other chronic pain disorders. However, little is known about the prevalence of EDS among people with secondary chronic headaches. ⋯ Almost one out of four subjects with secondary chronic headache reported EDS with no differences between the various secondary chronic headaches.

The periaqueductal gray (PAG) dysfunction was recognized in migraine, and the nonspecific PAG lesions were also observed in episodic migraine (EM) recently. However, the PAG volume change was not totally detected in EM up to now. Herein, the aim of this study was to investigate altered PAG volume in EM patients based on high resolution brain structural image. ⋯ PAG volume expansion may be the direct impairment evidence on the brain in EM, and could be considered as a diagnostic and evaluated imaging biomarker in migraine.
