Clinical Characteristics and Outcomes of Multiple Sclerosis and Neuromyelitis Optica Spectrum Disorder With Brainstem Lesions as Heralding Prodrome.

Front Neurol 2022 9;13:836337. Epub 2022 May 9.

Department of Neurosurgery, Wayne State University School of Medicine, Detroit, MI, United States.

Objective: The present study sought to differentiate multiple sclerosis and neuromyelitis optica spectrum disorder patients at their first attack by describing and distinguishing their clinical features, radiographic characteristics, and immunologic characteristics of serum and cerebrospinal fluid.

Methods: We retrospectively studied 58 patients with multiple sclerosis (MS) and 52 patients with neuromyelitis optica spectrum disorder (NMOSD) by referencing brainstem lesions as the prodromal events. Their demographics and presentation at the time of the first attack was evaluated including their gender, age, clinical features of the first attack, the expanded disability status scale (EDSS), brainstem lesion(s) by head MRI, and immunological indices of serum and cerebrospinal fluid.

Video head impulse testing to differentiate vestibular neuritis from posterior circulation stroke in the emergency department: a prospective observational study.

BMJ Neurol Open 2022 3;4(1):e000284. Epub 2022 May 3.

Department of Neurophysiology, Liverpool Hospital, Liverpool, New South Wales, Australia.

Background And Aims: Vertigo is a common presentation to the emergency department (ED) with 5% of presentations due to posterior circulation stroke (PCS). Bedside investigations such as the head impulse test (HIT) are used to risk stratify patients, but interpretation is operator dependent. The video HIT (v-HIT) provides objective measurement of the vestibular-ocular-reflex (VOR) and may improve diagnostic accuracy in acute vestibular syndrome (AVS). Read More

Discordant horizontal-torsional nystagmus: a sign of posterior semicircular canal dysfunction.

J Neurol 2022 May 11. Epub 2022 May 11.

Department of Neurology, Seoul National University College of Medicine, Seoul, South Korea.

In central as well as peripheral vestibular lesions, right-beating horizontal nystagmus is almost always associated with clockwise (top poles of the eyes beating to the right ear) torsional nystagmus when observed and vice versa (concordant nystagmus). This study aimed to determine the etiologies and mechanisms of horizontal and torsional nystagmus beating in the opposite directions (discordant nystagmus). We reviewed the medical records of 16 consecutive patients with discordant horizontal-torsional nystagmus who had been evaluated at the dizziness clinics of Seoul National University Bundang Hospital (n = 11, from March 2003 to March 2021) and Korea University Medical Center (n = 5, from March 2019 to March 2021).

The HINTS examination and STANDING algorithm in acute vestibular syndrome: A systematic review and meta-analysis involving frontline point-of-care emergency physicians.

PLoS One 2022 5;17(5):e0266252. Epub 2022 May 5.

West Moreton Health Service, Ipswich, Queensland, Australia.

This systematic review aims to evaluate whether point-of-care emergency physicians, without special equipment, can perform the HINTS examination or STANDING algorithm to differentiate between central and non-central vertigo in acute vestibular syndrome with diagnostic accuracy and reliability comparable to more specialized physicians (neuro-ophthalmologists and neuro-otologists). Previous research has concluded that emergency physicians are unable to utilize the HINTS examination with sufficient accuracy, without providing any appropriate education or training. A comprehensive systematic search was performed using MEDLINE, Embase, the Cochrane CENTRAL register of controlled trials, Web of Science Core Collection, Scopus, Google Scholar, the World Health Organization International Clinical Trials Registry Platform, and conference programs and abstracts from six medical organizations.

Circ_0000811 acts as a miR-15b sponge and inhibits Prkar2a-mediated JAK2/STAT1 pathway to attenuate cerebral ischemic vertigo.

Cell Death Discov 2022 May 4;8(1):247. Epub 2022 May 4.

Department of Neurology, Shengjing Hospital of China Medical University, 110004, Shenyang, P.R. China.

Circular RNAs (circRNAs) have been noted to express in the brain and thus participate in various diseases related to the central nervous system. However, the potential role of circRNAs in cerebral ischemia (CI)-induced vertigo remains unknown. We initially predicted through bioinformatics analysis the poor expression of circ_0000811 related to CI. Read More

Structural Motility, Institut Curie, Paris Université Sciences et Lettres, Sorbonne Université, CNRS UMR144, F-75005 Paris, France.

Ménière's disease is a chronic illness characterized by intermittent episodes of vertigo associated with fluctuating sensorineural hearing loss, tinnitus and aural pressure. This pathology strongly correlates with a dilatation of the fluid compartment of the endolymph, so-called hydrops. Dexamethasone is one of the therapeutic approaches recommended when conventional antivertigo treatments have failed. Read More

A case of cerebrotendinous xanthomatosis with brain and spinal involvement without tendon xanthomas: Identification of a novel mutation of the CYP27A1 gene.

J Clin Lipidol 2022 Apr 3. Epub 2022 Apr 3.

Department of Neurology, 417 Army Share Fund Hospital, 10-12 Monis Petraki Str., PO 11521, Athens, Greece.

Cerebrotendinous xanthomatosis (CTX) is a rare inherited disorder of the alternative pathway of bile acid biosynthesis, due to mutation(s) of the gene CYP27A1, leading to sterol 27-hydroxylase deficiency. The latter results in a systematic deposition of cholestanol and cholesterol to the central nervous system and tendons, premature cataract, as well as the manifestation of systematic symptoms, such as chronic diarrhea, osteoporosis, and premature atherosclerosis. Due to its marked clinical heterogeneity, prompt diagnosis of this disorder is challenging. Read More

Downbeat nystagmus becomes attenuated during walking compared to standing.

J Neurol 2022 Apr 12. Epub 2022 Apr 12.

German Center for Vertigo and Balance Disorders, University Hospital, LMU, Munich, Germany.

Downbeat nystagmus (DBN) is a common form of acquired fixation nystagmus related to vestibulo-cerebellar impairments and associated with impaired vision and postural imbalance. DBN intensity becomes modulated by various factors such as gaze direction, head position, daytime, and resting conditions. Further evidence suggests that locomotion attenuates postural symptoms in DBN. Read More

Nystagmus only with fixation in the light: a rare central sign due to cerebellar malfunction.

J Neurol 2022 Apr 9. Epub 2022 Apr 9.

Department of Neurology, Dizziness Center, Clinical Neuroscience Center, Seoul National University Bundang Hospital, Seongnam, South Korea.

Fixation nystagmus refers to the nystagmus that appears or markedly increases with fixation. While relatively common in infantile (congenital) nystagmus, acquired fixation nystagmus is unusual and has been ascribed to lesions involving the cerebellar nuclei or the fibers projecting from the cerebellum to the brainstem. We aimed to report the clinical features of patients with acquired fixation nystagmus and discuss possible mechanisms using a model simulation and diagnostic significance. Read More

Cupulolithiasis as an Alternative Mechanism for Pseudo-spontaneous Nystagmus in Horizontal Canal Benign Paroxysmal Positional Vertigo.

OTO Open 2022 Jan-Mar;6(1):2473974X221089847. Epub 2022 Mar 29.

Department of Neurology, Medical University of Vienna, Vienna, Austria.

Benign paroxysmal positional vertigo of the horizontal semicircular canal may present a differential diagnostic challenge. In addition to the classical positional nystagmus, a persistent nystagmus in a seated position occasionally occurs, so-called pseudo-spontaneous nystagmus (PSN), which can be mistaken for a central or peripheral spontaneous nystagmus. We report a case with cupulolithiasis of the horizontal semicircular canal presenting with horizontal PSN in a sitting position, with implications for a new pathomechanism of PSN. Read More

Relationship Between the Onset of Ménière's Disease and Sympathetic Hyperactivity.

Front Neurol 2022 17;13:804777. Epub 2022 Mar 17.

Department of Otorhinolaryngology, St. Marianna University School of Medicine, Kanagawa, Japan.

Objective: The pathogenesis of Ménière's disease is still largely unknown; however, it is known to be strongly associated with stress. Excessive stress can cause hyperactivity of the sympathetic autonomic nervous system. With the aim of understanding changes in sympathetic hyperactivity before and after Ménière's disease, we compared autonomic nervous function in patients in a stable phase of Ménière's disease and that in healthy adults.
