Some of the principles of the pharmacologic management of migraine are echoed in urgent discussions of the future of headache care in the USA and around the world. From adverse events to tolerance, addiction, medication overuse and medication persistence, solutions to the pathophysiologic puzzles, and management difficulties in migraine can be found by paying closer attention to patient reports and by facilitating greater patient involvement in the treatment process. Similarly, listening to the patient as customer in the process of value-based care, so adaptable for the problem of migraine, is the solution to the health care crisis we face in so many countries.

We aimed to provide a descriptive analysis of embolic stroke of undetermined etiology (ESUS) population based on a long-term prospective stroke registry. We retrospectively analyzed data collected in a detailed registry regarding consecutive patients admitted for first-ever ischemic stroke (IS) between January 2001 and December 2015. We used Org 10172 in Acute Stroke Treatment classification supplemented with ESUS criteria proposed by the Cryptogenic Stroke/ESUS International Working Group. ⋯ ESUS patients ≤ 60 years were more frequently independent at discharge than ESUS patients > 60 years. Approximately 11% of patients from our registry met ESUS criteria. ESUS patients were younger when compared to all other stroke etiologies, suffered less severe strokes, and had more favorable outcome at discharge than other groups except for those with small vessel disease strokes.

Review Meta Analysis
Association between TBK1 mutations and risk of amyotrophic lateral sclerosis/frontotemporal dementia spectrum: a meta-analysis.
Recently, mutations in TBK1 (TANK-binding kinase 1) have been reported to be a cause of amyotrophic lateral sclerosis/frontotemporal dementia (ALS/FTD) spectrum, but the relationship between them remains unclear owing to the small sample size and low mutation rate. Therefore, we performed a two-stage meta-analysis to investigate the frequency of TBK1 mutations in ALS/FTD patients and the association between the mutations and risk of ALS/FTD spectrum. In the first stage, 12 studies involving 4173 ALS/FTD patients were included. ⋯ In the second stage, 7 studies involving 3146 cases and 4856 controls were enrolled. Results showed that TBK1 LoF mutations were associated with a significant increased risk for ALS/FTD spectrum (OR 11.78; 95% CI 4.21-33.00; p < 0.0001), while TBK1 missense mutations were associated with a moderately increased susceptibility for ALS/FTD spectrum (OR 1.62; 95% CI 1.19-2.19; p = 0.002). In conclusion, TBK1 LoF and missense mutations are not frequently found in ALS/FTD patients, and both of them are associated with an increased risk for ALS/FTD spectrum.

Independent component analysis (ICA) is one of the most popular and valid methods to investigate the default mode network (DMN), an intrinsic network which attracts particular attention in amnestic mild cognitive impairment (aMCI). However, previous studies present inconsistent results regarding the topographical organization of the DMN in aMCI. Therefore, we conducted a quantitative, voxel-wise meta-analysis of resting-state ICA studies using Seed-based d Mapping to establish the most consistent pattern of DMN functional connectivity alterations in aMCI. ⋯ Patients with aMCI exhibited reliably lower DMN functional connectivity than the healthy controls in the bilateral precuneus/posterior cingulate cortices and medial temporal lobes, which are implicated in episodic memory deficits. Moreover, an exploratory meta-regression analysis revealed that greater severity of global cognitive impairment in the patient groups was associated with stronger functional connectivity in the bilateral medial frontal cortices (including the anterior cingulate cortices), left angular gyrus, and right temporal pole extending to the middle temporal gyrus, likely reflecting a compensatory mechanism for maintaining cognitive efficiency. This meta-analysis identifies a consistent pattern of aberrant DMN functional connectivity in aMCI, which facilitates understanding of the neurobiological substrates of this disease.
