| Neuro-oncology: Stability of medulloblastoma subgroups at tumour recurrence Jacques Grill & Christelle Dufour Published online: 10 December 2013 p5 | doi:10.1038/nrneurol.2013.256 Medulloblastomas can be categorized into four molecular subgroups. A new report shows, for the first time, that these tumours remain in the same subgroup at relapse, and the molecular subgroup influences the pattern of relapse. These findings indicate that this developmentally defined classification is robust, although its relationship to prognosis remains uncertain. Full Text | PDF | |||||||||||||||||||||||||||||||||||||
| Movement disorders: Tourette syndrome—beyond swearing and sex? Mary May Robertson Published online: 03 December 2013 p6 | doi:10.1038/nrneurol.2013.248 Gilles de la Tourette syndrome (GTS) is often perceived as the 'swearing disease', yet coprolalia affects only 10-15% of individuals with this condition. As highlighted in a new study, GTS has many phenotypes, some of which are sex-related. Could gender—that is, culturally established roles—also affect the phenotype?

| Parkinson disease: Low vitamin D and Parkinson disease—a causal conundrum Marian L. Evatt Published online: 03 December 2013 p8 | doi:10.1038/nrneurol.2013.252 Increasing evidence suggests that Parkinson disease (PD) should be included on the growing list of diseases associated with vitamin D insufficiency. A recent study reconfirms this association and supports the monitoring of vitamin D concentrations in patients with PD. The conundrum of causality regarding this association, however, remains unanswered. Full Text | PDF | |||||||||||||||||||||||||||||||||||||
| Migraine: Differential effects of placebos in migraine clinical trials Peer C. Tfelt-Hansen & Anders Hougaard Published online: 10 December 2013 p10 | doi:10.1038/nrneurol.2013.255 According to a new systematic review, placebo treatment in clinical trials of migraine prophylaxis results in responder rates ranging from 0-56%, probably owing to variable combinations of spontaneous improvement and genuine placebo effects. Clinicians who treat patients with migraine should be aware of the potential nonspecific effects of any treatment modality. Full Text | PDF | |||||||||||||||||||||||||||||||||||||
| Epilepsy: Effects of exposure to antiepileptic drugs during development Frank Vajda Published online: 10 December 2013 p11 | doi:10.1038/nrneurol.2013.254 A population-based study of babies who were exposed to antiepileptic drugs (AEDs) in utero revealed impairment of fine motor and social skills as early as 6 months of age. Such neurocognitive changes were independent of breastfeeding status at 18 months, suggesting that breastfeeding can be recommended in women receiving AEDs.

| Neurodegenerative disease: Mapping the natural history of Huntington disease Roger A. Barker & Sarah L. Mason Published online: 10 December 2013 p12 | doi:10.1038/nrneurol.2013.253 A key challenge to improving the design of clinical trials in Huntington disease (HD) has been the limited data on the natural history of HD. A recent prospective longitudinal study has provided important information in this regard, which could be useful for future translation of disease-modifying therapies for early-stage HD.

| The emerging agenda of stratified medicine in neurology Paul M. Matthews, Paul Edison, Olivia C. Geraghty & Michael R. Johnson Published online: 10 December 2013 p15 | doi:10.1038/nrneurol.2013.245 In this Review, Paul Matthews and colleagues outline the potential benefits of a stratified approach to health-care delivery in neurology, including reduced risk of adverse events from medicines, and lower treatment costs. They provide examples of neurological diseases in which stratified medicine is already improving treatment, and consider challenges to implementation of these approaches.

| Primary cilia in neurodevelopmental disorders Enza Maria Valente, Rasim O. Rosti, Elizabeth Gibbs & Joseph G. Gleeson Published online: 03 December 2013 p27 | doi:10.1038/nrneurol.2013.247 Primary cilia are hair-like, non-motile sensory organelles that are found on the surface of almost all cells in vertebrates. Defects in these organelles can lead to a wide array of disorders known as ciliopathies. In this Review, Valente et al. focus on ciliopathies with major neurological involvement, describing their clinical features and known pathogenetic mechanisms, and discussing the possible aetiologies of associated brain malformations.

| Bringing rigour to translational medicine David W. Howells, Emily S. Sena & Malcolm R. Macleod Published online: 19 November 2013 p37 | doi:10.1038/nrneurol.2013.232 Effective treatments are lacking for most neurological disorders, and progress in developing new therapeutic agents has been frustratingly slow. Howells and colleagues explore the barriers to the development of treatments for these conditions, focusing predominantly on the stroke field. They highlight the current deficiencies and conflicts of interest in preclinical and clinical research, and suggest ways in which scientific rigour might be improved.

| Delayed neurological deterioration after subarachnoid haemorrhage R. Loch Macdonald Published online: 10 December 2013 p44 | doi:10.1038/nrneurol.2013.246 Subarachnoid haemorrhage (SAH) has a high case fatality. In addition to neurological injury occurring at the time of haemorrhage, delayed neurological deterioration can occur days later owing to processes such as cerebral vasospasm and microthrombosis, which culminate in delayed cerebral ischaemia. R. Loch Macdonald reviews the pathophysiology of these delayed complications of SAH, and outlines existing treatments and drugs in development for this indication.
