Review
The onset of menopause, marked by hormonal fluctuations and a decline in estrogen levels, is suggested to be linked to increased susceptibility to vestibular disturbances. Estrogen, beyond its established association with reproductive physiology, plays modulatory roles in various physiological systems, including neurosensory function. The vestibular system, crucial for balance and spatial orientation, is influenced by hormonal changes during menopause, potentially contributing to the emergence of vertigo symptoms. This interplay between hormones and the vestibular system is a burgeoning area of research with clinical implications, offering insights into novel diagnostic and therapeutic approaches for managing postmenopausal women with vestibular disorders. The article reviews current scientific literature, delves into the hormonal intricacies of menopause, and investigates potential mechanisms underlying the connection between hormonal fluctuations and vertigo symptoms.

Comprehensive evaluation of the mechanism of Banxia Baizhu Tianma Decoction in ameliorating posterior circulation ischemia vertigo based on integrating fecal short-chain fatty acids and 16S rRNA sequencing.
Posterior circulation ischemia vertigo (PCIV) is vertebrobasilar insufficiency resulting in vertigo. Banxia Baizhu Tianma Decoction (BBTD) is broadly applied to treat PCIV in China, but its efficacy and detailed mechanism remains unclear. Therefore, this study aims to investigate the effects of BBTD on PCIV, and identify important gut microbiota and its derived short-chain fatty acid (SCFA) changes and the detailed mechanism through 16 S rRNA sequencing with SCFAs profiling. In this study, the model of PCIV was established by surgical ligation of the right subclavian artery (RSCA) and right common carotid artery (RCCA). We found that BBTD administration effectively reduced the volume of cerebral infarction and improved neurologic functions, reduced neuronal apoptosis and neuroinflammatory. Moreover, BBTD significantly modulated the diversity and composition of the gut microbiota, including increasing the relative abundance of Lactobacillus, Prevotella and Akkermansia and decreasing relative abundances of Lachnospiraceae, Bacteroidetes (S24-7) and Ruminococcaceae. BBTD treatment also increased propionate content. Propionate mediates the the recovery of neurological functions and anti-apoptotic effects of BBTD in PCIV rat. Our findings wish to discover the potential mechanism of BBTD treatment on PCIV and promote its clinical application.

BACKGROUND
Migraine and dizziness often coexist, with vestibular migraine (VM) presenting with vestibular symptoms and headaches. Calcitonin gene-related peptide (CGRP) may be involved in motion-induced symptoms; however, studies on the use of anti-CGRP monoclonal antibodies (mAbs) for the treatment of VM have yielded conflicting results. This study aimed to clarify the effectiveness of anti-CGRP mAbs in VM treatment.
METHODS
This retrospective observational cohort study, conducted between 1 January 2021 and 31 March 2023, assessed 12 Japanese patients with VM who were treated with anti-CGRP mAbs (CGRP group) for 6 months and 11 Japanese patients who received standard of care for VM and served as controls. Clinical questionnaires and equilibrium tests were administered, with primary outcomes including changes in Dizziness Handicap Inventory (DHI) scores compared with baseline values. Objective variables included the DHI score and explanatory variables included demographic data, balance test results, head-up tilt (HUT) test results, vestibular test results and questionnaire survey results. Analysis of variance was used to assess the treatment effects of anti-CGRP mAbs, and multivariate regression analysis was performed to identify mAb responders.
RESULTS
After 6 months, the CGRP group showed significant improvements in DHI scores [0 versus 6 months, odds ratio (95% confidence interval): 22.01 (0.13-43.88)] and number of vertigo/dizziness attacks per month [0 versus 6 months: 10.28 (2.80-17.76)]. No significant difference was observed in the control group [DHI scores, 0 versus 6 months: 0.65 (-26.84 to 28.14); number of vertigo/dizziness attacks per month, 0 versus 6 months: - 8.07 (- 23.77 to 7.62)]. Multivariate regression analysis showed that autonomic function at baseline was associated with mAb response in patients [β estimates (95% confidence interval): 3.63 (0.21-7.06)].
CONCLUSIONS
Treatment with anti-CGRP mAbs was more effective than conventional treatment in preventing migraine in patients with VM. While the identified factors associated with treatment responsiveness offer valuable insights into personalised treatment approaches, further prospective studies are warranted to validate the findings due to our study's retrospective design and limited sample size.

OBJECTIVES
The aim of this study was to evaluate vestibulo-ocular reflex (VOR) of individuals over 60 years of age who have not been diagnosed with a specific vestibular pathology.
METHODS
Bilateral six-semicircular canal video head impulse test (vHIT), Dizziness Handicap Inventory and European Evaluation of Vertigo scales were applied to participants.
RESULTS
In total, 103 participants were included in the study (75 male, 28 female), and the mean age was 69.35 ± 7.41 years. The mean age of 7th decade group was 64.32±3.12 (59 participants; 38 male, 21 female), and the mean age of 8th decade and older group was 76.11±5.93 (44 participants; 37 male, 7 female). No significant differences were found between the VOR gains of the lateral or vertical semicircular canals between the 7th decade and 8th decade and older groups (p>0.05). In the 8th decade and older group, the presence of right lateral semicircular canal corrective saccade and left posterior semicircular canal corrective saccade showed a positively moderate correlation with VOR gains of the same semicircular canals (r=0.455, p=0.002, and r=0.518, p=0.001, respectively). No significant correlation was found between age and VOR gain in the 7th decade group, however, there was a negatively weak correlation between age and left lateral semicircular canal VOR gain (r=-0.366, p=0.017) in the 8th decade and older group.
CONCLUSION
While assessing the age-related changes in VOR using vHIT, it must be considered that the changes related to aging of the vestibular system begin to emerge in the population over 70 years of age, and corrective saccade findings may be more informative than VOR gains in revealing these changes.

(1) Background: Patients affected by Ménière's disease can experience Tumarkin's syndrome, which is characterized by postural instability, gait abnormalities, and, occasionally, an abrupt loss of balance known as vestibular drop attack or Tumarkin's crisis. In this study, semicircular canal plugging is proposed as the definitive treatment for this condition. The outcomes of this type of surgery are discussed. (2) Methods: A total of 9 patients with a confirmed diagnosis of Ménière disease suffering from Tumarkin crisis underwent posterior semicircular canal plugging. These patients were assessed with Video Head Impulse Tests, vestibular evoked myogenic potentials, and Pure Tone Audiometry preoperatively and postoperatively. (3) Results: VHIT showed a postoperative decrease in PSC gain median (Preop. 0.86 and postop. 0.52; < 0.009). No statistically significant differences were described for the anterior semicircular canal and the lateral semicircular canal. No patient experienced new Tumarkin crisis after the surgical treatment. (4) Conclusions: Our ten years of experience with posterior semicircular canal plugging in Ménière disease patients with Tumarkin's syndrome has shown that this type of surgical procedure is successful in controlling Tumarkin's crisis, with high patient satisfaction and little worsening in hearing level.

Persistent dizziness and balance deficits are common, often with unknown etiology. Persistent Postural-Perceptual Dizziness (3PD) is a relatively new diagnosis with symptoms that may include dizziness, unsteadiness, or non-vertiginous dizziness and be persistent the majority of time over a minimum of 90 days. The purpose of this case series was to investigate short-term outcomes of reducing dizziness symptoms using a manual therapy intervention focused on restoring mobility in the fascia using a pragmatically applied biomechanical approach, the Fascial Manipulation method (FM), in patients with 3PD. The preliminary prospective case series consisted of twelve ( = 12) patients with persistent complaints of dizziness who received systematic application of manual therapy to improve fascial mobility after previously receiving vestibular rehabilitation. The manual therapy consisted of strategic assessment and palpation based on the model proposed in the FM Stecco Method. This model utilizes tangential oscillations directed toward the deep fascia at strategic points. Six males ( = 6) and females ( = 6) were included with a mean age of 68.3 ± 19.3 years. The average number of interventions was 4.5 ± 0.5. Nonparametric paired sample -tests were performed. Significant improvements were observed toward the resolution of symptoms and improved outcomes. The metrics included the Dizziness Handicap Inventory and static and dynamic balance measures. The Dizziness Handicap Inventory scores decreased (i.e., improved) by 43.6 points ( = -3.1 and = 0.002). The timed up and go scores decreased (i.e., improved) by 3.2 s ( = -2.8 and = 0.005). The tandem left increased (i.e., improved) by 8.7 s ( = 2.8 and = 0.005) and the tandem right increased (i.e., improved) by 7.5 s ( = 2.8 and = 0.005). Four to five manual therapy treatment sessions appear to be effective for short-term improvements in dizziness complaints and balance in those with 3PD. These results should be interpreted with caution as future research using rigorous methods and a control group must be conducted.

KEY CLINICAL MESSAGE
Although it is rare, physicians should be familiar with the presentation of lateral medullary syndrome (LMS). Urgent neuroimaging is crucial to distinguish LMS from other causes of stroke. The majority experience significant improvement within months.
ABSTRACT
Lateral medullary syndrome is a rare type of stroke resulting from a vascular event in the lateral part of the medulla oblongata. Loss of pain and temperature in the ipsilateral side of the face, and contralateral side of the body along with ipsilateral ataxia, vertigo, nystagmus, dysphagia, and hiccups are the hallmark clinical presentation. We reported a case of a 51-year-old male with a long history of smoking and newly discovered hypertension who presented complaining of vomiting, regurgitation, and hiccups for 1 month; tingling and numbness sensation in the left side of the face and the right side of the body, and unsteady gait for 2 weeks. Neurological examinations revealed left-sided ptosis and miosis, diminished sensation of the three divisions of the trigeminal nerve, deviated uvula to the right side, absent gag reflex, and intention tremors. The patient received the appropriate treatment; showed a good recovery with his symptoms, was able to walk unsteady, and was discharged after 10 days in a good condition.

Critical illness survivors commonly face impairments, such as intensive care unit-acquired weakness (ICUAW) which is characterized by muscle weakness and sensory deficits. Despite these symptoms indicating potential balance deficits, systematic investigations and validated assessments are lacking. Therefore, we aimed to assess balance function using the Mini-BESTest, evaluate its psychometric properties, and identify associated variables. Balance was assessed post-ICU discharge (V1) and at discharge from inpatient neurorehabilitation (V2) in patients with ≥ 5 days of invasive ventilation. Mini-BESTest measurement characteristics were evaluated in an ambulatory subgroup. A multiple linear regression was conducted. The prospective cohort study comprised 250 patients (34% female, 62 ± 14 years, median ICU stay 55 days). Median Mini-BESTest scores improved significantly from V1 (5 (IQR 0-15)) to V2 (18.5 (10-23)) with a large effect size. Excellent inter-rater and test-retest reliabilities of the Mini-BESTest were observed (ICC = 0.981/0.950). Validity was demonstrated by a very high correlation with the Berg Balance Scale (ρ = 0.90). No floor or ceiling effects were detected. Muscle strength, cognitive function, cerebral disease, critical illness polyneuropathy/myopathy, and depression were significantly associated with balance. Despite significant improvements during the rehabilitation period, balance disorders were prevalent in critical illness survivors. Ongoing therapy is recommended. Due to its excellent psychometric properties, the Mini-BESTest is suitable for use in critical illness survivors.Registration: The study was registered at the German Clinical Trials Register (DRKS00021753, date of registration: 2020-09-03).

The superior canal dehiscence syndrome is a pathology that affects the arcuate eminence creating a "third window" between the inner ear and the middle fossa. This condition can lead to symptoms such as hearing loss, autophony, or sound-induced vertigo. Traditionally, surgical treatment has been performed by microscope-assisted temporal craniotomy, but when the dehiscence is in the medial part of the arcuate eminence the bone defect may not be seen. We present case series treated at our institution diagnosed of superior canal dehiscence syndrome involving the medial slope of the arcuate eminence. During surgery, the bone defect could not be visible with traditional microscopic techniques. Nonetheless, by introducing the endoscope with the 0º and 30º optics, the dehiscence could be clearly observed and treated correctly. Our results show a clinical improvement without side effects or complications in the patients undergoing this technique. Endoscope-assisted surgery is a safe procedure and provides a better visualization of medial defects.
