Objective: This study aimed to evaluate the differences in the mean retinal nerve fiber layer (RNFL) thickness using optical coherence tomography (OCT) in patients with early stage central vertigo with or without vertebrobasilar stenosis detected by Doppler ultrasound.
Materials And Methods: A total of 50 patients with ischemic vertigo and 50 healthy individuals were included in the study. The distinction between central and peripheral vertigo was determined by physical and neurological examinations and the Dix-Hallpike maneuver. For all patients, the mean RNFL thickness was determined using OCT performed by 2 independent ophthalmologists.
Results: There were no significant differences between the groups in terms of age and sex distribution (p>0.05). On average, in superior, inferior, and temporal quadrants, there was a statistically significant difference between the control and patient groups (p<0.001).
Conclusion: The retina may be affected in patients with ischemic vertigo because of atherosclerotic ischemic lesions in the carotid and vertebral arteries. Neuroimaging methods and OCT were evaluated together to develop a new diagnostic approach. With OCT, which is a non-invasive method, early and more objective differential diagnosis will be possible.

C-reactive protein-to-albumin ratio and systemic immune-inflammatory index as potential markers in distinguishing acute cerebellar infarction from benign paroxysmal positional vertigo.

Objectives: To investigate the potential utility of the C-reactive protein-to-albumin ratio (CAR) and the systemic immune-inflammatory index (SII) as a biomarker in distinguishing between BPPV and acute cerebellar infarction (ACI) due to posterior inferior cerebellar artery (PICA) involvement.
Methods: The data of 2545 patients registered in our hospital database between 2017 and 2024 with a diagnosis of vertigo were retrospectively analyzed and 102 patients with benign paroxysmal positional vertigo (BPPV) and 100 patients with ACI were included in the study. Mann-Whitney U test, Chi-square test, or Fisher's exact test were used to compare variables between the two groups.
Diverse phenotype of Ménière's disease associated with family history, thyroid disorder, migraine and associated disorders.

Objective: To better understand the clinical phenotype of Ménière's disease (MD), we examined family history, thyroid disorder, migraine, and associated disorders in complaints of people living with MD.
Method: We designed the study as a retrospective and examined data gathered from 912 participants with MD. Their data were originally collected by the Finnish Ménière Federation (FMF).
Intravenous thrombolysis in patients with acute dizziness or imbalance and suspected ischemic stroke-systematic review.

Background: Correct identification of those patients presenting with an acute vestibular syndrome (AVS) or an acute imbalance syndrome (AIS) that have underlying posterior-circulation stroke (PCS) and thus may benefit from revascularization (intravenous thrombolysis (IVT), endovascular therapy (EVT)) is important. Treatment guidelines for AVS/AIS patients are lacking. We reviewed the evidence on acute treatment strategies in AVS/AIS focusing on predictors for IVT/EVT and outcome.

Schwannomas (SCs) are benign tumors composed of neoplastic Schwann cells and are relatively uncommon intracranially. Although these tumors are frequently associated with neurofibromatosis type 2 (NF2), they may also arise idiopathically, and their pathogenesis remains poorly understood. A 70-year-old Caucasian man presented with a two-month history of vertigo, gait imbalance, and decreased visual acuity in the left eye accompanied by photophobia, nausea, vomiting, and occasional headaches.

Introduction: A subset of undifferentiated vertigo cases can be attributed to dangerous central causes such as posterior circulation ischemic stroke (PCIS) or transient ischemic attack (TIA). Due to a lack of validated clinical risk scoring tools, there is currently high heterogeneity in emergency department (ED) neuroimaging practices for patients presenting with undifferentiated vertigo. Therefore, this study assessed the utility of head and neck CT with angiography (CTA) for risk stratifying ED patients presenting with vertigo.
