PURPOSE OF REVIEW: Multiple sclerosis is a heterogeneous disorder. Biomarkers to monitor disease activities are highly desirable especially because of the recent shift toward personalized medicine that coincides with the expansion of disease-modifying therapy. The visual system is highly involved in multiple sclerosis, and the rapid advancement of ophthalmic techniques has boosted the development of potential ocular biomarkers for multiple sclerosis management. RECENT FINDINGS: Recent studies have found that the rapid thinning of the peripapillary retinal nerve fiber layer and ganglion cell-inner plexiform layer (GCIPL) occurs in the progressive stage...

PURPOSE OF REVIEW: Optic nerve head elevation can be associated with vision loss. This review provides an update regarding key features of optic disc drusen (ODD) compared with papilledema from increased intracranial pressure and optic disc edema from other causes. RECENT FINDINGS: Clinical history and funduscopic examination are not sufficient to correctly diagnose different causes of optic nerve head elevation. Multimodal ophthalmic imaging is noninvasive and should be used as first-line diagnostic testing to distinguish optic disc edema or papilledema from pseudoedema...

PURPOSE OF REVIEW: To describe the background, principles and implementation of the Stroke Action Plan for Europe 2018--2030 (SAP-E) in the perspective of the current COVID-19 pandemic. RECENT FINDINGS: SAP-E sets targets for the implementation of evidence-based preventive actions and stroke services to 2030. A recent mapping of stroke care in Europe has documented massive inequalities and even in high-income European countries access to reperfusion therapy and mortality after ischaemic stroke varies significantly...

PURPOSE OF REVIEW: The aim of this study was to describe the impact of the COVID-19 outbreak on the epidemiology, cause and clinical characteristics of incident stroke in different settings and populations. RECENT FINDINGS: Several studies have shown that there are three main themes in the epidemiology of stroke during the COVID-19 pandemic: COVID-19 seems to be associated with stroke in a significant number of patients. This association has been reported in several clinical series, mainly from China...

PURPOSE OF REVIEW: The aim of this article is to review the current literature on endovascular treatment of acute ischemic stroke in the aftermath of the coronavirus disease 2019 (COVID-19) lockdown. RECENT FINDINGS: The outbreak of the COVID-19 has had effect of unprecedented magnitude on the social, economic and personal aspects around the globe. Healthcare providers were forced to expand capacity to provide care to the surging number of symptomatic COVID-19 patients, while maintaining a fully operating service for all non-COVID patients...

PURPOSE OF REVIEW: The aim of this study was to present the latest advances in giant cell arteritis (GCA) care, and recent national and international rheumatology societies guidance which influences clinical practice. RECENT FINDINGS: Cranial ultrasound reduces diagnostic delay and improves clinical outcomes. Immediate high dose glucocorticoids remain the standard treatment for GCA. Controlled trial evidence using Tocilizumab, an interleukin-6 receptor antagonist, shows good clinical efficacy with steroid-sparing effects...

PURPOSE OF REVIEW: Direct oral anticoagulants (DOAC) are crucial for the prevention of thromboembolic events in patients with nonvalvular atrial fibrillation. Drug adherence by the patient but also adherence to guidelines by the physician are suboptimal. This review highlights aspects of DOAC treatment during the coronavirus disease 2019 (COVID-19) pandemic and selected challenging scenarios. RECENT FINDINGS: For patients with a newly diagnosed indication for oral anticoagulation, a new interim clinical guidance recommends starting DOAC instead of vitamin K antagonists if DOAC are not contraindicated...

PURPOSE OF REVIEW: The coronavirus disease 2019 (COVID-19) pandemic challenges many healthcare systems. This review provides an overview of the advantages of telemedicine during times of pandemic and the changes that have followed the outbreak of the COVID-19 disease. RECENT FINDINGS: Telemedicine has been utilized during infectious outbreaks for many years. COVID-19 has induced a variety of changes in laws (i.e. data privacy protection) and reimbursement procedures to accelerate new setups of telemedicine...

PURPOSE OF REVIEW: Negative findings on neuroimaging are part of the diagnostic criteria for idiopathic intracranial hypertension (IIH), a syndrome characterized by increased intracranial pressure (ICP). Some positive neuroimaging findings are associated with increased ICP, but their role in diagnosis of IIH has not been established. We provide an overview of these findings and their relevance for diagnosis of raised intracranial pressure. RECENT FINDINGS: MRI acquisition techniques have significantly improved in the last few decades leading to better characterization of the intracranial changes associated with IIH, including empty sella turcica, optic nerve tortuosity, distension of the optic nerve sheath, posterior globe flattening, slit-like ventricles, and venous sinus stenosis...

PURPOSE OF REVIEW: Homonymous visual field defects are a common sequela of stroke, and are assumed to be permanent within a few weeks of the event. Because consensus about the efficacy of rehabilitation is lacking, visual therapy is rarely prescribed. Here, we review current rehabilitation options and strategies in the translational pipeline that could change these perspectives. RECENT FINDINGS: The mainstays of available therapy for homonymous visual defects are compensation training and substitution, which allow patients to better use their spared vision...

PURPOSE OF REVIEW: The aim of this article is to summarize the evidence for visual impairment as a risk factor for visual hallucinations in neurologic disease and recent advances in our understanding of the central visual pathways that mediate this association. RECENT FINDINGS: Recent studies have described the prevalence Charles Bonnet syndrome and questioned its lack of association with cognitive impairment, used advanced neuroimaging to show that disinhibition of the occipital lobe is involved in the pathogenesis of visual hallucinations in Parkinson's disease, and demonstrated that visual impairment because of eye disease is a consistent risk factor for visual hallucinations across a number of different neurodegenerative disease populations...
