Development and Initial Validation of a Meniere's Disease Quality of Life Instrument: The MenQOL.

Objective: To design and validate a disease-specific quality of life instrument for Meniere's disease.

Methods: We used a sequential process of expert input, patient focus groups, and analyses of responses to draft questionnaires to create a 24-item Meniere's disease quality of life (MenQOL) instrument. The MenQOL and the SF-36v2 were administered to a cohort of 50 patients with Meniere's disease and 60 comparison patients with tinnitus, vertigo, or hearing loss from other causes identified at a tertiary academic center.

Vestibular migraine and persistent postural perceptual dizziness.

Dizziness is a common symptom among patients in primary care, general neurology, and headache clinic practices. Vestibular migraine is conceptualized as a condition of recurrent attacks of vestibular symptoms attributed to migraine. It is now considered the most common cause of spontaneous episodic vertigo.

Most patients with disorders of gut-brain interaction receive pharmacotherapy with major or moderate drug-gene interactions.

Background: How variations predicted by pharmacogenomic testing to alter drug metabolism and therapeutic response affect outcomes for patients with disorders of gut- brain interaction is unclear.

Aims: To assess the prevalence of pharmacogenomics-predicted drug-gene interactions and symptom outcomes for patients with disorders of gut-brain interaction.

Methods: Patients who were treated in our clinical practice for functional dyspepsia/bowel disorder underwent pharmacogenomic testing.

Clinical Characterization, Course, and Treatment of Othello Syndrome: A Case Series and Systematic Review of the Literature.

Background: Othello syndrome (OS) is a condition characterized by a delusion of jealousy that one's spouse is having extramarital affairs. As in the eponymous Shakespearean tragedy, there is an unfortunate risk of violence. For patients with these symptoms, consultation-liaison psychiatrists may be asked to assist with evaluating the differential diagnosis, assessing safety, and developing treatment options.

Persistent Postural-Perceptual Dizziness: Review and Update on Key Mechanisms of the Most Common Functional Neuro-otologic Disorder.

Persistent postural-perceptual dizziness (PPPD) is a functional neuro-otologic (vestibular) disorder manifesting dizziness, unsteadiness, or nonspinning vertigo lasting 3 months or more and exacerbated by upright posture, active or passive motion, and complex visual stimuli. PPPD is the most common cause of chronic vestibular symptoms. Early pathophysiologic models of PPPD emphasized the adverse effects of anxiety on postural control and spatial orientation.

Functional neurological seizures and migraine: A systematic review and case series.

Background: The seizure subtype of functional neurological disorder (FND-seizures) is a common neuropsychiatric condition manifesting with episodic epilepsy-like events. Despite the common belief that FND-seizures are precipitated by psychological stressors, neurological disorders may also be triggers. In 1890, Babinski described four cases of FND symptoms associated with migraine attacks.

The Psychometric Properties of the 9-Item Vestibular Activities Avoidance Instrument.

Objective: The purpose of this study was to establish the psychometric properties of the 9-Item Vestibular Activities Avoidance Instrument (VAAI-9), a patient-reported outcome measure developed to identify fear avoidance beliefs in persons with vestibular disorders.

Methods: This prospective cohort study included 100 participants 18 years and older seeking care at a balance disorders clinic for dizziness. Participants completed the VAAI-9, the Dizziness Handicap Inventory (DHI), and other patient-reported outcomes at the initial visit and the 3-month follow-up.

Real-World Implementation of Best-Evidence Cancer Distress Management: Truly Comprehensive Cancer Care.

Background: Cancer distress management is an evidence-based component of comprehensive cancer care. Group-delivered cognitive behavioral therapy for cancer distress (CBT-C) is the first distress treatment associated with replicated survival advantages in randomized clinical trials. Despite research supporting patient satisfaction, improved outcomes, and reduced costs, CBT-C has not been tested sufficiently within billable clinical settings, profoundly reducing patient access to best-evidence care.

Outcomes and Patient Experience in Individuals With Longstanding Dizziness.

Purpose: This study aimed to describe the relationship between changes in pre and post self-perceived dizziness handicap, scores on the patient health questionnaire, and perceptions of patient's value of being evaluated and managed by a multidisciplinary team.

Method: Seventy-eight patients completed the Dizziness Handicap Inventory (DHI) and Patient Health Questionnaire-Fourth Edition (PHQ-4) questionnaires post multidisciplinary clinical consultations and testing for the chief complaints of dizziness, unsteadiness, vertigo, or balance problems. The diagnoses of each patient were recorded from the clinical reports of each specialty consultation and were classified as structural, functional, or psychiatric.

Predictors of persistent postural-perceptual dizziness (PPPD) and similar forms of chronic dizziness precipitated by peripheral vestibular disorders: a systematic review.

Background: The literature on predictors of persistent postural-perceptual dizziness (PPPD) following peripheral vestibular insults has not been systematically reviewed.

Methods: We systematically reviewed studies on predictors of PPPD and its four predecessors (phobic postural vertigo, space-motion discomfort, chronic subjective dizziness and visual vertigo). Investigations focused on new onset chronic dizziness following peripheral vestibular insults, with a minimum follow-up of 3 months.

Case Report: Right Insular Stroke Causing Simultaneous Onset of a Functional Vestibular Disorder and Psychiatric Disorder-Persistent Postural-Perceptual Dizziness and Post-stroke Depression.

Introduction: Persistent postural-perceptual dizziness (PPPD) is a chronic functional vestibular disorder that can be precipitated by acquired brain injuries. Poststroke depression (PSD) is the most common psychiatric sequela of stroke, affecting 33% of stroke survivors. Pathophysiologic mechanisms of PPPD and PSD are not fully understood.

Functional neurological disorder: new subtypes and shared mechanisms.

Functional neurological disorder is common in neurological practice. A new approach to the positive diagnosis of this disorder focuses on recognisable patterns of genuinely experienced symptoms and signs that show variability within the same task and between different tasks over time. Psychological stressors are common risk factors for functional neurological disorder, but are often absent.

Structural connectivity of autonomic, pain, limbic, and sensory brainstem nuclei in living humans based on 7 Tesla and 3 Tesla MRI.

Autonomic, pain, limbic, and sensory processes are mainly governed by the central nervous system, with brainstem nuclei as relay centers for these crucial functions. Yet, the structural connectivity of brainstem nuclei in living humans remains understudied. These tiny structures are difficult to locate using conventional in vivo MRI, and ex vivo brainstem nuclei atlases lack precise and automatic transformability to in vivo images.

Magnitude Estimates Orchestrate Hierarchal Construction of Context-Dependent Representational Maps for Vestibular Space and Time: Theoretical Implications for Functional Dizziness.

Maintaining balance necessitates an accurate perceptual map of the external world. Neuro-physiological mechanisms of locomotor control, sensory perception, and anxiety systems have been viewed as separate entities that can on occasion affect each other (i.e.

Electrical stimulation of the cochlea for treatment of chronic disabling tinnitus: an open-label trial towards the development of an implantable device.

Background: Chronic tinnitus affects millions of people globally and constitutes the most commonly compensated disability among military service members in the United States. Existing treatment options largely surround helping patients cope with their disease as opposed to directly suppressing tinnitus perception. The current study investigated the efficacy of electrical stimulation of the cochlea on chronic disabling tinnitus.

Functional connectome of brainstem nuclei involved in autonomic, limbic, pain and sensory processing in living humans from 7 Tesla resting state fMRI.

Despite remarkable advances in mapping the functional connectivity of the cortex, the functional connectivity of subcortical regions is understudied in living humans. This is the case for brainstem nuclei that control vital processes, such as autonomic, limbic, nociceptive and sensory functions. This is because of the lack of precise brainstem nuclei localization, of adequate sensitivity and resolution in the deepest brain regions, as well as of optimized processing for the brainstem.

Characterization of Postural Sway in Patients With Persistent Postural-Perceptual Dizziness (PPPD) Using Wearable Motion Sensors.

Objective: To extend previous investigations of postural control in patients with persistent-postural perceptual dizziness (PPPD).

Study Design: Case-controlled, cross-sectional, observational investigation.

Setting: Tertiary care center.

Brain Correlates of Persistent Postural-Perceptual Dizziness: A Review of Neuroimaging Studies.

Persistent postural-perceptual dizziness (PPPD), defined in 2017, is a vestibular disorder characterized by chronic dizziness that is exacerbated by upright posture and exposure to complex visual stimuli. This review focused on recent neuroimaging studies that explored the pathophysiological mechanisms underlying PPPD and three conditions that predated it. The emerging picture is that local activity and functional connectivity in multimodal vestibular cortical areas are decreased in PPPD, which is potentially related to structural abnormalities (e.

Invasive Electrophysiology for Circuit Discovery and Study of Comorbid Psychiatric Disorders in Patients With Epilepsy: Challenges, Opportunities, and Novel Technologies.

Intracranial electroencephalographic (iEEG) recordings from patients with epilepsy provide distinct opportunities and novel data for the study of co-occurring psychiatric disorders. Comorbid psychiatric disorders are very common in drug-resistant epilepsy and their added complexity warrants careful consideration. In this review, we first discuss psychiatric comorbidities and symptoms in patients with epilepsy.
