Objective : To perform a comprehensive lipid profiling to evaluate potential lipid metabolic differences between patients with amyotrophic lateral sclerosis (ALS) and controls, and to provide a more profound understanding of the metabolic abnormalities in ALS. Methods : Twenty patients with ALS and 20 healthy controls were enrolled in a cross-sectional study. Untargeted lipidomics profiling in fasting serum samples were performed by optimized UPLC-MS platforms for broad lipidome coverage. Datasets were analyzed by univariate and a variety of multivariate procedures. Results : We provide the most comprehensive blood lipid profiling of ALS to date, with a total of 416 lipids measured. Univariate analysis showed that 28 individual lipid features and two lipid classes, triacylglycerides and oxidized fatty acids (FAs), were altered in patients with ALS, although none of these changes remained significant after multiple comparison adjustment. Most of these changes remained constant after removing from the analysis individuals treated with lipid-lowering drugs. The non-supervised principal component analysis did not identify any lipid clustering of patients with ALS and controls. Despite this, we performed a variety of linear and non-linear supervised multivariate models to select the most reliable features that discriminate the lipid profile of patients with ALS from controls. These were the monounsaturated FAs C24:1n-9 and C14:1, the triglyceride TG(51:4) and the sphingomyelin SM(36:2). Conclusions : Peripheral alterations of lipid metabolism are poorly defined in ALS, triacylglycerides and certain types of FAs could contribute to the different lipid profile of patients with ALS. These findings should be validated in an independent cohort.

Background and Objectives: Steinert's disease or myotonic dystrophy type 1 (MD1), (OMIM 160900), is the most prevalent myopathy in adults. It is a multisystemic disorder with dysfunction of virtually all organs and tissues and a great phenotypical variability, which implies that it has to be addressed by different specialities with experience in the disease. The knowledge of the disease and its management has changed dramatically in recent years. This guide tries to establish recommendations for the diagnosis, prognosis, follow-up and treatment of the complications of MD1., Material and Methods: Consensus guide developed through a multidisciplinary approach with a systematic literature review. Neurologists, pulmonologists, cardiologists, endocrinologists, neuropaediatricians and geneticists have participated in the guide., Recommendations: The genetic diagnosis should quantify the number of CTG repetitions. MD1 patients need cardiac and respiratory lifetime follow-up. Before any surgery under general anaesthesia, a respiratory evaluation must be done. Dysphagia must be screened periodically. Genetic counselling must be offered to patients and relatives., Conclusion: MD1 is a multisystemic disease that requires specialised multidisciplinary follow-up., (Copyright © 2018 Sociedad Española de Neurología.

«Apuntes en Neurologia» is an initiative in which prominent national and international leaders, with broad academic recognition, came together to synthesise the most outstanding clinical aspects within their area of interest and to discuss the latest developments in a more accessible language. Understanding the factors that affect the onset and progression of any neurological disease through a review is important to be able to develop strategies to reduce the burden of these diseases. Moreover, knowledge of the clinical aspects is essential to solve the problems of daily clinical practice. The data collected here reflect the weight of evidence and some of them anticipate a promising future in the treatment of these diseases. This first edition focuses on common paroxysmal neurological disorders such as migraine, epilepsy and sleep disorders, as well as neurodegenerative disorders such as Parkinson's disease and cognitive impairment. These are clearly different pathologies, although some of them such as migraine and epilepsy, may share clinical symptoms. Sleep disorders, however, are important manifestations of neurodegenerative diseases that are sometimes clinically apparent long before the onset of other neurological symptoms. After recalling pathophysiology and diagnosis, the current review focuses on bringing together the main advances in five of the major neurological diseases.

Introduction: For many years carbamazepine (CBZ) has been the reference drug for the treatment of partial epileptic seizures. However, the problems related with its pharmacokinetics and safety have led to the development of other derivatives, such as oxcarbazepine (OXC) and, more recently, eslicarbazepine acetate (ESL), which do not display these drawbacks., Development: In clinical practice, the possibility of replacing CBZ or OCX by ESL is a relatively frequent occurrence, the aim being to maintain the efficacy of its predecessors and benefit from the advantages in terms of the pharmacokinetics and safety of this latter derivative. To achieve this, it is essential to have an approximate dose equivalence and exchange protocol. This review offers a practical reasoned model for carrying out the change., Conclusions: The shift from OXC to ESL can be completed from one day to the next with a dose equivalence of 1-1.5 to 1. Replacement of CBZ by ESL must be more progressive, and the dose equivalence is established as 1-1.3 to 1.

Introduction: The characteristics of some population groups (patients with comorbidities, women of childbearing age, the elderly) may limit epilepsy management. Antiepileptic treatment in these patients may require adjustments., Development: We searched articles in Pubmed, clinical practice guidelines for epilepsy, and recommendations by the most relevant medical societies regarding epilepsy in special situations (patients with comorbidities, women of childbearing age, the elderly). Evidence and recommendations are classified according to the prognostic criteria of Oxford Centre of Evidence-Based Medicine (2001) and the European Federation of Neurological Societies (2004) for therapeutic interventions., Conclusions: Epilepsy treatment in special cases of comorbidities must be selected properly to improve efficacy with the fewest side effects. Adjusting antiepileptic medication and/or hormone therapy is necessary for proper seizure management in catamenial epilepsy. Exposure to antiepileptic drugs (AED) during pregnancy increases the risk of birth defects and may affect fetal growth and/or cognitive development. Postpartum breastfeeding is recommended, with monitoring for adverse effects if sedative AEDs are used. Finally, the elderly are prone to epilepsy, and diagnostic and treatment characteristics in this group differ from those of other age groups. Although therapeutic limitations may be more frequent in older patients due to comorbidities, they usually respond better to lower doses of AEDs than do other age groups., (Copyright © 2014 Sociedad Española de Neurología.
