#4
REVIEW
Ronald M Lazar, Amelia K Boehme
PURPOSE OF REVIEW: Aphasia is a common feature of stroke, affecting 21-38% of acute stroke patients and an estimated 1 million stroke survivors. Although stroke, as a syndrome, is the leading cause of disability in the USA, less is known about the independent impact of aphasia on stroke outcomes. RECENT FINDINGS: During the acute stroke period, aphasia has been found to increase length of stay, inpatient complications, overall neurological disability, mortality, and to alter discharge disposition...

REVIEW
Zhichuan Li, Lanyan Fang, Wenlei Jiang, Myong-Jin Kim, Liang Zhao
PURPOSE OF REVIEW: This review summarizes the current FDA practice in developing risk- and evidence-based product-specific bioequivalence guidances for antiepileptic drugs (AEDs). RECENT FINDINGS: FDA's product-specific guidance (PSG) for AEDs takes into account the therapeutic index of each AED product. Several PSGs for AEDs recommend fully replicated studies and a reference-scaled average bioequivalence (RS-ABE) approach that permit the simultaneous equivalence comparison of the mean and within-subject variability of the test and reference products...

REVIEW
Amy K Wagner
PURPOSE OF REVIEW: The purpose of this review is to summarize how "-omics" technologies can inform rehabilitation-relevant outcomes for a range of populations with neurologically related disability by including outcome metrics linked to the World Health Organization's International Classification of Functioning, Disability, and Health (WHO-ICF) domains of impairments in body function, activity limitations, and participation restrictions. RECENT FINDINGS: To date, nearly every area of medicine uses biomarkers in some capacity to aid in understanding how personal biology informs clinical care...

REVIEW
Christopher Goshgarian, Philip B Gorelick
PURPOSE OF REVIEW: The purpose of this review is to discuss the prevention of venous thromboembolism (VTE) in stroke patients. We discuss use of oral anticoagulation and other interventions for the prevention of VTE. A new class of medications, non-vitamin K antagonist oral anticoagulants (NOACs), have been successfully trialed for the prevention of VTE. We review the data and guidance statements for VTE prevention. RECENT FINDINGS: Warfarin and vitamin K antagonist drugs have been the mainstay of VTE prevention for decades...

REVIEW
Roland Veltkamp, Jan Purrucker
PURPOSE OF REVIEW: We review the current evidence for medical and surgical treatments of spontaneous intracerebral hemorrhage (ICH). RECENT FINDINGS: Therapy with hemostatic agents (e.g. factor VIIa and tranexamic acid) if started early after bleeding onset may reduce hematoma expansion, but their clinical effectiveness has not been shown. Rapid anticoagulation reversal with prothrombin concentrates (PCC) plus vitamin K is the first choice in vitamin K antagonist-related ICH...

#9
REVIEW
David Coughlin, David J Irwin
PURPOSE OF REVIEW: Tauopathies represent a spectrum of incurable and progressive age-associated neurodegenerative diseases that currently are diagnosed definitively only at autopsy. Few clinical diagnoses, such as classic Richardson's syndrome of progressive supranuclear palsy, are specific for underlying tauopathy and no clinical syndrome is fully sensitive to reliably identify all forms of clinically manifest tauopathy. Thus, a major unmet need for the development and implementation of tau-targeted therapies is precise antemortem diagnosis...

REVIEW
David K Chen, Esha Sharma, W Curt LaFrance
PURPOSE OF REVIEW: In this review, we elucidate the evaluation process involved in the diagnosis of psychogenic non-epileptic seizures (PNES). Minimum clinical criteria required to attain this diagnosis via a staged approach are delineated. The psychological underpinnings and management of PNES from the neurologists' perspective are also explored. RECENT FINDINGS: Helpful clues can be deduced from history-taking, seizure semiology, ictal/peri-ictal physical exam, and ictal/inter-ictal EEG data...

REVIEW
Jeffrey M Politsky
PURPOSE OF REVIEW: The relationship of brain tumors and seizures remains poorly understood. This article is an overview of the epidemiology, etiology, and diagnostic and treatment approaches of tumor-related epilepsy primarily with regard to glial-based tumors, the most commonly considered brain tumor in this field. RECENT FINDINGS: Over the past many years, several novel etiologic mechanisms to explain how tumors induce seizures have been developed, which this article reviews, including the roles of glutamate-induced excitotoxicity, matrix metalloproteinases, isocitrate dehydrogenase, methylguanine methyltransferase, and functional network connectivity...

REVIEW
Mahesh V Jayaraman, Ryan A McTaggart, Mayank Goyal
PURPOSE OF REVIEW: Trials demonstrating marked benefit of mechanical thrombectomy (MT) for acute stroke caused by large vessel occlusion (LVO) in the anterior circulation have been the most significant advance in acute ischemic stroke in the past 20 years. However, despite this marked advance, there are still many hurdles to improving access to thrombectomy worldwide. Additionally, despite these advances, a substantial portion of patients with LVO still are left disabled. RECENT FINDINGS: The major randomized trials focused on patients within 6 h from symptom onset, with occlusion of the ICA or proximal MCA, small amount of permanently damaged brain, and a moderate to large clinical deficit...

REVIEW
Latha Velayudhan, Dominic Ffytche, Clive Ballard, Dag Aarsland
This article reviews current treatment strategies and recent advances for the Lewy body dementias (LBDs). Current available symptom treatment strategies are based on monoaminergic, cholinergic and glutaminergic neurotransmitter systems. Relatively robust evidence exists for cholinesterase inhibitors for cognitive impairment in LBD and in Parkinson's disease for antidepressants, clozapine and recently pimavanserin for psychosis. interpidine (RVT 101) and nelotanserin are currently under investigation. Non-pharmacological interventions, such as cognitive stimulation, physical exercises and neuromodulation strategies, may be useful in Parkinson's disease but have not yet been tested in dementias...

REVIEW
Andreas Puschmann
PURPOSE OF REVIEW: This article reviews was to review genes where putative or confirmed pathogenic mutations causing Parkinson's disease or Parkinsonism have been identified since 2012, and summarizes the clinical and pathological picture of the associated disease subtypes. RECENT FINDINGS: Newly reported genes for dominant Parkinson's disease are DNAJC13, CHCHD2, and TMEM230. However, the evidence for a disease-causing role is not conclusive, and further genetic and functional studies are warranted...

REVIEW
Nicholas L Zalewski, W Oliver Tobin
PURPOSE OF REVIEW: Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) is a recently described treatable, inflammatory, brainstem predominant encephalomyelitis. The diagnosis of CLIPPERS is challenging without a specific biomarker, and thus it is important to consider if both the clinical and radiographic features are consistent with the diagnosis, or rather a disease mimicker. RECENT FINDINGS: Many patients with CLIPPERS-like lesions have been described in the literature with follow-up revealing a range of alternative diagnoses, such as malignancies, vasculitis, and other specific inflammatory diseases...

REVIEW
Hans-Christoph Diener, Richard Bernstein, Robert Hart
PURPOSE OF THE REVIEW: The purpose of the study was to review the literature on cryptogenic stroke and embolic stroke of undetermined stroke (ESUS). Cryptogenic stroke according to TOAST criteria is a stroke which is not due to cardiogenic embolism, small vessel disease with lacunes or large vessel disease of brain supplying arteries. In the context of secondary stroke prevention studies, cryptogenic stroke is not operationally defined. RECENT FINDINGS: The new concept of "embolic stroke of undetermined source" (ESUS) provides an operational definition...

REVIEW
Eric Prince, Shahin Hakimian, Andrew L Ko, Jeffrey G Ojemann, Michelle S Kim, John W Miller
MRI-guided laser interstitial thermal therapy (MgLiTT) uses a narrow diameter cannula to stereotactically target and heat deeper cerebral structures. This technique produces a precise lesion in the brain with great reliability because the localized tissue temperature change is monitored in real time. Because MgLiTT minimizes injury to surrounding brain, it appears to have a lower risk of affecting normal neurological function, and because it is done through a burr hole, there is less operative risk, less discomfort, and shorter hospitalizations...

REVIEW
Allison Crowell, Kelly G Gwathmey
PURPOSE OF REVIEW: The sensory neuronopathies are sensory-predominant polyneuropathies that result from damage to the dorsal root and trigeminal sensory ganglia. This review explores the various causes of acquired sensory neuronopathies, the approach to diagnosis, and treatment. RECENT FINDINGS: Diagnostic criteria have recently been published and validated to allow differentiation of sensory neuronopathies from other polyneuropathies. On the basis of serial electrodiagnostic studies, the treatment window for the acquired sensory neuronopathies has been identified as approximately 8 months...

REVIEW
Neha Raghavan, Giuseppe Tosto
PURPOSE OF REVIEW: We aimed to summarize the recent advances in genetic findings of Alzheimer's disease (AD), focusing on traditional single-marker and gene approaches and non-traditional ones, i.e., polygenic and epistatic components. RECENT FINDINGS: Genetic studies have progressed over the last few decades from linkage to genome-wide association studies (GWAS), and most recently studies utilizing high-throughput sequencing. So far, GWASs have identified several common variants characterized by small effect sizes (besides APOE-ε4)...
