    Abstract Dizziness is a prevalent symptom in the general population and is among the most common reasons patients present for medical evaluations. This article focuses on high yield information to support primary clinicians in the efficient and effective evaluation and management of dizziness. Key points are as follows: do not anchor on the type of dizziness symptom, do use symptom timing and prior medical history to inform diagnostics probabilities, do evaluate for hallmark examination findings of vestibular disorders, and seek out opportunities to deliver evidence-based interventions particularly the canalith repositioning maneuver and gaze stabilization exercises.

    Abstract Purpose of review: This article provides a summary of the evaluation and treatment of patients presenting with episodic positional dizziness.
    Recent findings: Positional components are nearly ubiquitous among diagnoses of dizziness, so it can be challenging to classify patients with episodic positional dizziness simply based on the history of present illness. Overreliance on the presence of a report of positional components has likely resulted in misapplication or misinterpretation of positional testing and negative experiences with maneuvers to treat positional dizziness. The prototypical episodic positional dizziness disorder is benign paroxysmal positional vertigo (BPPV). BPPV is caused by free-floating particles in a semicircular canal that move in response to gravity. The diagnosis is made by identifying the characteristic patterns of nystagmus on the Dix-Hallpike test. Particle repositioning for BPPV is supported by randomized controlled trials, meta-analyses, and practice guidelines. Other disorders that can present with episodic positional dizziness are migraine dizziness, central lesions, and light cupula syndrome.
    Summary: Episodic positional dizziness is a common presentation of dizziness. Neurologists should prioritize identifying and treating BPPV; doing so provides an important opportunity to deliver effective and efficient care. Providers should also recognize that positional components are common in most causes of dizziness and, therefore, should not over-rely on this part of the history of presentation when considering the diagnosis and management plan.

    Abstract Background: Vascular region of infarct is part of the International Classification of Diseases-10 (ICD-10) coding scheme for ischemic stroke. These data could potentially be used for studies about vascular location, such as comparisons of anterior versus posterior circulation stroke. The objective of this study was to evaluate the validity of these subcodes.
    Methods: We selected a random sample of 100 hospitalizations specifying 50 with anterior circulation ICD-10 ischemic stroke (carotid, anterior cerebral artery [CA], middle CA) and 50 with posterior circulation stroke (vertebral, basilar, cerebellar, posterior CA). The gold standard primary vascular distribution was scored using imaging studies and reports, blinded to the subcode. We compared gold-standard distribution to coded distribution and calculated the operating characteristics of ICD-10 posterior circulation versus anterior circulation codes with the gold standard. We also calculated the kappa statistic for agreement across all 7 vascular regions.
    Results: In our population of 100 strokes, mean NIHSS was 8 (SD, 8). Head CT was performed in 95 % (95/100) and MRI in 77 % (77/100). The gold standard classified 55 primary posterior circulation strokes (26 PCA, 16 cerebellar, 8 basilar, 5 vertebral), 44 primary anterior circulation strokes (35 MCA, 6 carotid, 3 ACA), and 1 stroke with no infarct on imaging. The accuracy of the ICD-10 classification for primary posterior circulation stroke versus anterior circulation/no infarct was: sensitivity 89 % (49/55); specificity 98 % (44/45); positive predictive value 98 % (49/50); negative predictive value 88 % (44/50). The reliability of the 7-region classification was excellent (kappa 0.85).
    Conclusions: We found that ICD-10 classification of vascular location in routine practice correlates strongly with gold-standard localization for hospitalized ischemic stroke and supports validity in differentiating posterior versus anterior circulation. At a more granular vascular level, the location reliability was excellent, although limited data were available for some subcodes.

    Abstract The acute vestibular syndrome (AVS) is a label for presentations of new-onset severe dizziness, vertigo, or imbalance, with examination findings of nystagmus or gait unsteadiness. The prototypical AVS presentation is the acute unilateral vestibulopathy due to vestibular neuritis. Stroke is also a serious concern in patients with AVS. Most other peripheral vestibular disorders present as episodic or chronic syndromes. In this article, the diagnostic considerations, exam findings, and management of AVS are reviewed.

    Abstract High-quality health care delivery relies on a complex orchestration of the flow of patient data. Incorporating advanced artificial intelligence (AI) technologies into this delivery system has tremendous potential to improve health care, but also carries with it unique challenges. The nature of neurologic disease, and the current state of neurologic care delivery, makes this area of medicine well positioned for AI-driven innovation by 2035. Business, ethics, regulation, and medical education will need to evolve in concert. The information technology and data standards requirements for this potential transformation are underappreciated and will be a major driver of changes across the industry. Using AI on patient data to drive health care innovation to improve patients' lives as the primary goal will facilitate widespread acceptance and adoption of the practices required for a successful AI transformation in neurology. In planning the incorporation of AI into clinical practice, the tenets of rigorous research will need to be vigilantly applied to prevent unwarranted costs and inconveniences while promoting meaningful health outcomes.

    Abstract Benign paroxysmal positional vertigo (BPPV) is a very common condition in the population and an important cause of acute vertigo or dizziness in patients presenting to an emergency department (ED). Despite this, abundant evidence shows that current ED management of patients with BPPV is suboptimal. Common ED management processes include brain imaging and treatment with vestibular suppressant medications such as meclizine, neither of which is recommended by current guidelines. The most efficient management of BPPV is to perform a bedside test (Dix-Hallpike test) and then to treat the patients with a bedside positional (the Epley) maneuver. In this practical review we emphasize the efficient management for the most common form of BPPV-posterior canal BPPV. Using this management will reduce resource utilization (laboratory testing, brain imaging, specialist consultation), reduce ED length of stay, and reduce use of ineffective mediations that have side effects but little therapeutic effect. Application of these practices would improve important patient-centered outcomes such as symptom reduction, radiation exposure, side effects from medications, and less need for urgent follow-up with another health care provider. The article also discusses the approach to patients in whom the Dix-Hallpike and/or Epley maneuvers do not seem to work. This includes a discussion the second most common variant of BPPV (horizontal canal BPPV) and criteria for safe discharge of patients. Another important advantage of learning BPPV best practices is that it is enormously satisfying for the clinician, not unlike treating a child with a nursemaid's elbow.

    Abstract Coding and insurance reimbursement is a part of the healthcare system in the United States but is subject to periodic modifications. In addition to changes in the evaluation and management (E/M) codes that took effect in 2021, there are some differences in coding for some diagnostic vestibular function test procedures. Two new codes for vestibular myogenic evoked potential testing were added and previous codes for auditory evoked potential codes 92585 and 92586, which some facilities had used to bill for vestibular myogenic evoked potential testing, have been eliminated. This article outlines the current state of coding and reimbursement by CMS for vestibular procedures.

    Abstract Lecanemab, a novel amyloid-sequestering agent, recently received accelerated Food and Drug Administration approval for the treatment of mild dementia due to Alzheimer disease (AD) and mild cognitive impairment (MCI). Approval was based on a large phase 3 trial, Clarity, which demonstrated reductions in amyloid plaque burden and cognitive decline with lecanemab. Three major concerns should give us pause before adopting this medication: Its beneficial effects are small, its harms are substantial, and its potential costs are unprecedented. Although lecanemab has a clear and statistically significant effect on cognition, its effect size is small and may not be clinically significant. The magnitude of lecanemab's cognitive effect is smaller than independent estimates of the minimally important clinical difference, implying that the effect may be imperceptible to a majority of patients and caregivers. Lecanemab's cognitive effects were numerically smaller than the effect of cholinesterase inhibitors and may be much smaller. The main argument in lecanemab's favor is that it may lead to greater cognitive benefit over time. Although plausible, there is a lack of evidence to support this conclusion. Lecanemab's harms are substantial. In Clarity, it caused symptomatic brain edema in 11% and symptomatic intracranial bleeding in 0.5% of participants. These estimates likely significantly underestimate these risks in general practice for 3 reasons: (1) Lecanemab likely interacts with other medications that increase bleeding, an effect minimized in Clarity. (2) The Clarity population is much younger than the real-world population with mild AD dementia and MCI (age 71 years vs 85 years) and bleeding risk increases with age. (3) Bleeding rates in trials are typically much lower than in clinical practice. Lecanemab's costs are unprecedented. Its proposed price of $26,500 is based on cost-effectiveness analyses with tenuous assumptions. However, even if cost-effective, it is likely to result in higher expenditures than any other medication. If its entire target population were treated, the aggregate medication expenditures would be $120 billion US dollars per year-more than is currently spent on all medications in Medicare Part D. Before adopting lecanemab, we need to know that lecanemab is not less effective, vastly more harmful, and 100× more costly than donepezil.
