Intravenous thrombolysis or endovascular therapy for acute ischemic stroke associated with cervical internal carotid artery occlusion: the ICARO-3 study.
The aim of the ICARO-3 study was to evaluate whether intra-arterial treatment, compared to intravenous thrombolysis, increases the rate of favourable functional outcome at 3 months in acute ischemic stroke and extracranial ICA occlusion. ICARO-3 was a non-randomized therapeutic trial that performed a non-blind assessment of outcomes using retrospective data collected prospectively from 37 centres in 7 countries. Patients treated with endovascular treatment within 6 h from stroke onset (cases) were matched with patients treated with intravenous thrombolysis within 4.5 h from symptom onset (controls). ⋯ A. procedures, a potential benefit of I. A. treatment alone compared to I. V. thrombolysis was observed.

Letter ReviewAn update in sleep neurology: the latest bedtime stories.
In the 24/7 modern society, sleep disorders and the role of normal amounts and timing of sleep for health are often neglected by both doctors and their patients. Sleep has been said to be "of the brain, by the brain and for the brain" and the most immediate and obvious consequence of disrupted sleep is impaired brain function. This review will cover some of the recent papers published in both the Journal of Neurology and elsewhere in 2013/2014 that have advanced our knowledge of sleep and circadian rhythm disorders.

Relationship between iron accumulation and white matter injury in multiple sclerosis: a case-control study.
Despite the increasing development and applications of iron imaging, the pathophysiology of iron accumulation in multiple sclerosis (MS), and its role in disease progression and development of clinical disability, is poorly understood. The aims of our study were to determine the presence and extent of iron in T2 visible lesions and gray and white matter using magnetic field correlation (MFC) MRI and correlate with microscopic white matter (WM) injury as measured by diffusion tensor imaging (DTI). This is a case-control study including a series of 31 patients with clinically definite MS. ⋯ The GM mean diffusivity (MD) was inversely correlated with the MFC in the centrum semiovale (p < 0.001), and in the splenium of the corpus callosum (p < 0.001). Patients with MS have increased iron in the globus pallidus, putamen and centrum with a trend toward increased iron in all the brain structures. Quantitative iron evaluation of WM and GM may improve the understanding of MS pathophysiology, and might serve as a surrogate marker of disease progression.
