Efficacy and Pharmacological Appropriateness of Cinnarizine and Dimenhydrinate in the Treatment of Vertigo and Related Symptoms.

Int J Environ Res Public Health 2021 Apr 30;18(9). Epub 2021 Apr 30.

Dipartimento di Biomedicina, Neuroscienze e Diagnostica Avanzata (BiND), Sezione di Audiologia, Università Degli Studi di Palermo, Via del Vespro 129, 90127 Palermo, Italy.

Vertigo is not itself a disease, but rather a symptom of various syndromes and disorders that jeopardize balance function, which is essential for daily activities. It is an abnormal sensation of motion that usually occurs in the absence of motion, or when a motion is sensed inaccurately. Due to the complexity of the etiopathogenesis of vertigo, many pharmacological treatments have been tested for efficacy on vertigo. Read More

Department of Neurology, Lahey Hospital and Medical Center, 41 Mall Road, Burlington, MA 1805, USA; Tufts University School of Medicine, Burlington, MA, USA.

Vestibular symptoms, including dizziness, vertigo, and unsteadiness, are common presentations in the emergency department. Most cases have benign causes, such as vestibular apparatus dysfunction or orthostatic hypotension. However, dizziness can signal a more sinister condition, such as an acute cerebrovascular event or high-risk cardiac arrhythmia. Read More

[Vertigo and dizziness].

Ken Johkura

Rinsho Shinkeigaku 2021 Apr 17. Epub 2021 Apr 17.

Department of Neurology, Yokohama Brain and Spine Center.

Pathophysiology of vertigo/dizziness can be understood by eye deviation (nystagmus). In benign paroxysmal positional vertigo, eye deviation of causative semicircular canal stimulation is directly observed. In other peripheral vestibular disorders, eye deviation results from the sum of unilateral all semicircular canal disorders. Read More

Melatonin Exerts Anti-Inflammatory, Antioxidant, and Neuromodulatory Effects That Could Potentially Be Useful in the Treatment of Vertigo.

Int J Otolaryngol 2021 23;2021:6641055. Epub 2021 Mar 23.

Scientific Direction, Foltra Medical Center, Teo 15886, Spain.

The acute phase of vertigo involves multiple neurotransmitters, inflammatory mediators, and products of oxidative stress. The vestibular pathway has multiple melatonin receptors distributed along its path, both centrally and peripherally. In addition, melatonin has been shown to be a powerful antioxidant and anti-inflammatory agent against factors related to vertigo, such as Bax/caspases, interleukins, and chemokines. Read More

The cingulate oculomotor cortex.

Cortex 2021 May 4;138:341-355. Epub 2021 Mar 4.

German Center for Vertigo and Balance Disorders, Ludwig-Maximilians-University Munich, Munich, Germany; Institute for Neuroradiology, Ludwig-Maximilians-University Munich, Munich, Germany.

Knowledge about the relevance and extent of human eye movement control in the cingulate cortex to date is very limited. Experiments in non-human primates brought about evidence for a potentially central role of the dorsal bank of the cingulate sulcus in saccadic eye movements. In humans, a putative cingulate eye field (CEF) in the same region has been proposed; however, its function and location still remain controversial. Read More

[Bilateral vestibular hypofunction: a literature review and a case report].

Med Pr 2021 Apr 31;72(2):185-192. Epub 2020 Dec 31.

Śląski Uniwersytet Medyczny w Katowicach / Medical University of Silesia in Katowice, Katowice, Poland (Wydział Nauk o Zdrowiu w Katowicach, Zakład Anatomii / School of Health Sciences in Katowice, Department of Anatomy).

Bilateral vestibular hypofunction (BVH) is a rare disorder of the peripheral part of the balance organ, which may cause chronic vertigo and oscillopsia accompanying body movements. The chronic and severe nature of the symptoms and difficulties in maintaining balance and performing precise movements may cause the patient's withdrawal from professional activity. A frequently long period from the onset of the symptoms to the diagnosis of BVH, which should be based on the objective examination of the peripheral part of the vestibular organ, drastically reduces the chances of improving the patient's precise movement motility and significantly deteriorates the quality of life.

BMJ Open 2021 03 18;11(3):e046510. Epub 2021 Mar 18.

Department of Physiotherapy, University of Seville, Sevilla, Spain.

Introduction: Vestibular disorders in multiple sclerosis (MS) could have central or peripheral origin. Although the central aetiology is the most expected in MS, peripheral damage is also significant in this disease. The most prevalent effect of vestibular peripheral damage is benign paroxysmal positional vertigo (BPPV). Read More

[Positional vertigo variant].

Zh Nevrol Psikhiatr Im S S Korsakova 2021 ;121(2):88-91

Central Research Institute for Dentistry and Maxillofacial Surgery, Moscow, Russia.

The article describes case history and multiphase treatment of the patient with attacks of vertigo, initially regarded as the onset of Meniere's disease, but later qualified as secondary positional attacks with combined musculoskeletal pathology of the craniovertebral region and temporomandibular joint. Medicinal, local and surgical treatment led to the perfect result.

Clinical Implication of Corrective Saccades in the Video Head Impulse Test for the Diagnosis of Posterior Inferior Cerebellar Artery Infarction.

Front Neurol 2021 18;12:605040. Epub 2021 Feb 18.

Research Institute of Clinical Medicine, Jeonbuk National University Hospital-Biomedical Research Institute, Jeonbuk National University, Jeonju, South Korea.

In the present study, we characterized the vestibulo-ocular reflex (VOR) gain and properties of corrective saccades (CS) in patients with posterior inferior cerebellar artery (PICA) stroke and determined the best parameter to differentiate PICA stroke from benign peripheral vestibular neuritis (VN). In particular, we studied CS amplitude and asymmetry in video head impulse tests (vHITs) to discriminate these two less-studied disease conditions. The vHITs were performed within 1 week from symptom onset in patients with PICA stroke ( = 17), patients with VN ( = 17), and healthy subjects (HS, = 17). Read More

Agreement Between Physical Therapists in Diagnosing Benign Paroxysmal Positional Vertigo.

J Neurol Phys Ther 2021 04;45(2):79-86

Physical Therapy Department, University of the Sciences, Philadelphia, Pennsylvania (A.K.G.); Excel Physical Therapy, Blue Bell, Pennsylvania (A.T.); Willow Grove Physical Therapy, Willow Grove, Pennsylvania (M.F.); and WWS Physical Therapy and Vestibular Rehabilitation, Doylestown, Pennsylvania (W.W.S).

Background And Purpose: Individuals with benign paroxysmal positional vertigo (BPPV) are frequently referred to physical therapy for management, but little is known on how reliable therapists are at diagnosing BPPV. The purpose of the study was to examine the agreement between physical therapists in identifying nystagmus and diagnosing BPPV.

Methods: Thirty-eight individuals with complaints of positional vertigo, 19 from each of 2 clinics (clinics 1 and 2) that specialize in vestibular rehabilitation, had eye movements recorded using video goggles during positioning tests including supine-to-sit, supine roll, and Dix-Hallpike tests.
