Background: Differential diagnosis of persistent vertigo/dizziness in patients with a past history of vestibular neuritis (VN) and sudden deafness with vertigo (SDV) could sometimes be difficult for physicians due to variable vertiginous symptoms from rotatory to floating sensation.
Objectives: The main purpose of the present study was to examine the associations between the findings of otology/neurotology examinations in patients at the chronic stage after VN and SDV.
Material And Methods: We encountered 1789 successive vertigo/dizziness patients at the Vertigo/Dizziness Center in Nara Medical University between 2014 and 2018. Eighty-five patients were diagnosed as showing VN and 60 showed SDV according to the diagnostic guideline . The VN and SDV patients included 75 and 45 patients with chronic-stage of persistent vertigo/dizziness, of which 55 and 40 were enrolled into the present study.
Results: Persistent vertigo/dizziness after VN was attributable to delayed vestibular compensation (dVC: 33/55; 60.0%), secondary benign paroxysmal positional vertigo (sBPPV: 20/55; 36.4%), and secondary endolymphatic hydrops (sEH: 2/55; 3.6%), while that after SDV was attributable to sBPPV (20/40; 50.0%), sEH (16/40; 40.0%), and dVC (4/40; 10.0%).
Conclusion And Significance: The present results could allow to simplify differential diagnosis of persistent vertigo/dizziness after VN and SDV such diseases as dVC, sBPPV, or sEH.

Background: Dizziness/vertigo is one of the most common symptoms for which people seek healthcare. However, the healthcare expenditure attributable to dizziness/vertigo in South Korea remains poorly understood. We investigated the healthcare costs due to six major disorders causing dizziness/vertigo using claims data.

Article Synopsis
- Dizziness is a common reason for medical visits, and many patients may experience more than one vestibular disorder at the same time, affecting both diagnosis and treatment.
- The study involved analyzing data from 617 patients who completed a dizziness symptom profile before receiving vestibular function testing in a specialized clinic.
- Results indicated that there was a 42% chance that patients reported symptoms that didn't align with any known vestibular disorder, highlighting the complexity of diagnosing these conditions.

Objective: The study aimed to determine the etiological characteristics of patients with dizziness/vertigo attending a neurological clinic according to the criteria of the International Classification of Vestibular Disorders (ICVD), hoping to provide a valuable reference for clinicians to diagnose and treat dizziness/vertigo.
Method: A total of 638 consecutive patients with a chief complaint of dizziness/vertigo who attended the vertigo clinic of our neurology department from January 2019 to January 2020 were included. Clinical data of patients, including baseline data, medical history, neurological, neuro-otological, and auxiliary examination results were collected.

The widespread use of visual technologies such as Virtual Reality increases the risk of visually induced motion sickness (VIMS). Previously, the 6-item short version of the Visually Induced Motion Sickness Susceptibility Questionnaire (VIMSSQ short form) has been validated for predicting individual variation in VIMS. The aim of the current study was to investigate how the susceptibility to VIMS is correlated with other relevant factors in the general population.

Background: History and physical examination are key features to narrow the differential diagnosis of central versus peripheral causes in patients presenting with acute vertigo. We conducted a systematic review and meta-analysis of the diagnostic test accuracy of physical examination findings.
Methods: This study involved a patient-intervention-control-outcome (PICO) question: (P) adult ED patients with vertigo/dizziness; (I) presence/absence of specific physical examination findings; and (O) central (ischemic stroke, hemorrhage, others) versus peripheral etiology.
