Interviews

Understanding Lindsay-Hemenway Syndrome: Mechanisms, Diagnosis, and Treatment
May 21, 2025 Andrea Castellucci, MD This interview with Dr. Andrea Castellucci explores the Lindsay-Hemenway Syndrome (LHS), a rare clinical condition where Benign Paroxysmal Positional Vertigo (BPPV) follows an ipsilateral Acute Unilateral Vestibulopathy (AUVP). Dr. Castellucci discusses the pathophysiological mechanisms underlying LHS, emphasizing the anatomical and vascular factors that predispose patients to posterior semicircular canal (PSC) involvement. Diagnostic approaches, including bedside testing and instrumental assessments, are covered with detailed descriptions of nystagmus patterns and canal-specific findings. The interview also delves into management strategies for both AUVP and secondary BPPV, highlighting the role of targeted canalith repositioning maneuvers (CRM) to restore vestibular function and improve patient outcomes.

Why Should You Consider Using Automatic Real-Ear Measurements (AutoREM)?
April 14, 2025 Clayton Fisher, M.Cl.Sc IntroductionAs a clinician fitting hearing aids on a daily basis, I’m constantly seeking ways to enhance both the accuracy and efficiency of the fitting process.Experienced clinicians know that manually adjusting a hearing aid’s gain settings to optimize audibility can be time-consuming. The speed and complexity of this task often depend on factors such as the degree, type, and configuration of hearing loss, as well as the style and manufacturer of the hearing aid being used.Automatic real-ear measurement (AutoREM) is a valuable clinical tool that can streamline this process, helping clinicians achieve more accurate and consistent fittings, in less time.

Downbeat Nystagmus: What You Need to Know – An Expert Perspective
January 22, 2025 V. Marcelli, MD Downbeat nystagmus (DBN) is a common form of acquired central nystagmus, often linked to central vestibular dysfunction. This condition significantly affects a patient's vision and balance, making its diagnosis and management crucial. In this interview, we explore the clinical characteristics, underlying causes, diagnostic approaches, and available treatment options for DBN. We also discuss the role of Inventis Nystalyze, a modular system designed for precise eye movement analysis, in supporting the evaluation and management of DBN.

Possible Pathomechanisms Underlying a Spontaneous Reversal of Positional Nystagmus in PSC - BPPV
December 16, 2024 Andrea Castellucci, MD The interview with Dr. Andrea Castellucci delves into the phenomenon of Reversing Positional Nystagmus (RPN)—a spontaneous reversal of nystagmus direction in patients with Benign Paroxysmal Positional Vertigo (BPPV). Dr. Castellucci provides insights into how this phenomenon commonly occurs in the lateral semicircular canal variant (LSC-BPPV) and, less frequently, in the posterior semicircular canal (PSC-BPPV).The discussion focuses on:•Pathomechanisms potentially explaining RPN, including peripheral short-term adaptations of the vestibulo-ocular reflex (VOR) or the hypothesis of simultaneous lithiasis in both ampullary and non-ampullary canal arms.•The pivotal role of the video head impulse test (vHIT) in diagnosing and guiding physical therapy for complex BPPV cases associated with RPN.•The therapeutic challenges in managing BPPV with RPN, particularly the need for repeated canalith repositioning maneuvers.This interview offers a comprehensive overview of RPN, combining theoretical explanations and practical insights, while emphasizing the importance of advanced diagnostic tools in effectively managing these complex conditions.

The Audibility Index: An Indispensable Counseling Tool for Modern Hearing Clinics
April 8, 2024 Clayton Fisher, M.Cl.Sc In the ever-evolving field of audiology, the Audibility Index (AI) emerges as a pivotal tool, bridging the gap between clinical assessments and patient counseling. In an insightful interview with AudiologyOnline, Clayton Fisher delves into the nuances of AI, a metric that revolutionizes the understanding and communication of hearing loss. Fisher, leveraging his extensive expertise, unveils how the AI, or Speech Intelligibility Index (SII), quantifies the percentage of speech audible to an individual, offering a tangible perspective on auditory impairments. With the advent of modern audiometry suites like Maestro by Inventis, the manual task of calculating AI has been simplified, allowing clinicians to focus on comprehensive patient care. Through real-world applications and patient reactions, Fisher underscores the AI's significance in enhancing diagnostic accuracy and fostering patient acceptance of their auditory conditions. This discussion not only highlights the clinical utility of AI but also prompts a reevaluation of traditional methods, advocating for a more nuanced approach to diagnosing and addressing hearing loss.

Overview of Central Vestibular Disorders
November 27, 2023 Vishal Pawar Central vestibular disorders (CVDs) are caused by dysfunction of the central vestibular pathways in the brainstem, cerebellum and cerebrum. Approximately 10-12% of patients experiencing vestibular symptoms may have a central origin. Understanding the differential diagnosis is crucial as certain CVDs can lead to severe consequences. Some of the common CVDs leading to vestibular symptoms are vestibular migraine, stroke, multiple sclerosis, nutritional deficiency, and tumors. Differentiating central disorders from peripheral ones can be achieved through careful consideration of the patient's history, observation of eye movement abnormalities, identification of other neurological signs. Sometimes the symptoms and signs of CVDs can be similar to those of peripheral vestibular disorders, making it challenging to differentiate between the two. The dictum in identification of CVD’s is ‘Central signs are always central and Peripheral signs can be central or peripheral. Apart from imaging, vestibular testing with the help of Video-nystagmography (VNG) and Video-head impulse test (vHITs) can be of great help in this context. Understanding the detailed anatomy, physiology, function and clinical signs of dysfuction of central vestibular structures is crucial for a vestibular practitioner.

Complete and Incomplete Canalith Jam: Diagnosis of Atypical Variants of BPPV and Key Roles of Video-HIT
July 17, 2023 Andrea Castellucci, MD This interview is focused on the diagnosis of a particular subsample of BPPV variants including complete and incomplete canalith jam which can lead to atypical clinical scenario mimicking acute unilateral vestibular loss and CNS disorders. A particular mention is reserved to the key role of the video-HIT in the differential diagnosis, with the aim to increase clinicians’ awareness of the distinctive features of these atypical BPPV variants.

Minimum Stimulus Strategy in the Diagnosis of BPPV
May 22, 2023 Andrea Castellucci, MD This interview is focused on the Minimum Stimulus Strategy for the diagnosis of BPPV.
