Headache 

Read the Online Editorial Team's picks for the May 2013 issue:

Despite an incidence of approximately 3.8 million sports-related concussions per year, this injury remains poorly understood. Associated posttraumatic headache can provide a unique treatment challenge for medical personnel. The presence of new onset or persistent headache following injury often complicates return to play decisions. Although anecdotal reports and consensus guidelines exist, further evidence-based data are needed.

Atypical Resting State Functional Connectivity of Affective Pain Regions in Chronic Migraine

Chronic migraineurs (CM) have atypical affective responses to pain during and between migraine attacks. This study investigated the resting state functional connectivity (rs-fc) of affective pain processing brain regions in CM. Compared to controls, CM had atypical rs-fc between several affective regions and other brain regions that participate in pain processing. For some atypical connections there were correlations between rs-fc strength and number of years with chronic migraine.

Epicrania fugax (EF) is a distinct primary headache of recent description. It presents with painful paroxysms starting in a particular area of the head with rapid radiation forwards or backwards in a linear or zigzag trajectory through different nerve territories. To date 47 cases have been published, and now 19 new cases are reported.

Relative Associations of Trauma Exposure versus Posttraumatic Stress Disorder with Migraine
Smitherman, Todd, Kolivas, Elizabeth
The present study assessed the relative associations of trauma exposure versus posttraumatic stress disorder (PTSD) with migraine among a large non-clinical sample of young adults. Across multiple analyses, PTSD symptomatology predicted migraine diagnosis and related variables both before and after controlling for relevant covariates. Trauma exposure in the absence of PTSD was not significantly associated with migraine. PTSD appears far more relevant to migraine than is trauma exposure alone.
