PURPOSE OF REVIEW: Persistent postural-perceptual dizziness (PPPD) is a newly defined disorder of functional dizziness that in the International Classification of Diseases in its 11th revision (ICD-11) supersedes phobic postural vertigo and chronic subjective dizziness. Despite efforts to unify the diagnosis of functional (somatoform) dizziness, patients will present with a variety of triggers, perpetuating factors, and comorbidities, requiring individualized treatment. This article will review different treatment strategies for this common functional neurological disorder and provide practical recommendations for tailored therapy...

BACKGROUND: In patients with chronic benign paroxysmal positional vertigo (BPPV), i.e., chronic vestibular multicanalicular canalithiasis (CVMCC), abnormal signals are transmitted from diseased labyrinths via the healthy vestibular nuclei complex to their end organs. The vestibulo-thalamo-cortical reflex as proposed in vestibular migraine is just one of these reflexes. In a group of patients diagnosed with CVMCC otolith repositioning maneuvers specific for each semicircular canal (SCC) ameliorated pain and other symptoms in 90%...

Palinopsia is defined as the persistence or reappearance of images after cessation of the visual stimulus. One patient presented episodes of palinopsia after the functional loss of the 3 semicircular canals of the right ear while the otolithic function was preserved. None of classical causes was identified in this patient, intoxications, brain tumors, migraines, psychiatric disorders, etc. For a movement to be perceived as a single event, central processes of temporal integration are necessary to correct the shift between the rapid vestibular information, and the slow visual information...

BACKGROUND AND PURPOSE: Migraine has long been associated with unsteadiness and dizziness but postural control has not been studied in the ictal state. Here, we measured the stability of upright stance during migraine attacks. METHODS: Static balance was assessed prospectively in migraine patients (n=30) during quiet stance for 40 s on a posturographic force platform. Recordings were performed both ictally and in the pain-free interval. Subjects were assessed under 4 different conditions yielding different visual and proprioceptive feedback environments...

The discipline of affective neuroscience is concerned with the neural bases of emotion and mood. The past decades have witnessed an explosion of research in affective neuroscience, increasing our knowledge of the brain areas involved in fear and anxiety. Besides the brain areas that are classically associated with emotional reactivity, accumulating evidence indicates that both the vestibular and cerebellar systems are involved not only in motor coordination but also influence both cognition and emotional regulation in humans and animal models...

BACKGROUND: Dizziness is a common complaint in medicine. Nevertheless, there is a lack of valid data concerning the age and gender distribution of dizziness disorders within a larger population. Therefore, the aim of the present study is to undertake a representative epidemiological survey that examines all age groups of an entire population and describes the age and gender distribution of the most common peripheral vestibular disorders. METHODS: A population-based epidemiological survey based on confirmed ICD-10 codes, of an entire national population was performed...

OBJECTIVES: The International Classification of Functioning, Disability, and Health (ICF) Core Sets for Hearing Loss (CSHL) consists of short lists of categories from the entire ICF classification that are thought to be the most relevant for describing the functioning of persons with hearing loss. A comprehensive intake that covers all factors included in the ICF CSHL holds the promise of developing a tailored treatment plan that fully complements the patient's needs. The Comprehensive CSHL contains 117 categories and serves as a guide for multiprofessional, comprehensive assessment...

OBJECTIVES: The patulous Eustachian tube (PET) and superior semicircular canal dehiscence syndrome (SCDS) have similarity in their symptoms and similar effects caused by positional changes, causing difficulty in the differentiation between the two disorders. This report describes a case of both SCDS and PET that was eventually successfully treated. METHODS: A 68-year-old man presented with hyperacusis to his own footsteps and gait disturbance. He had been diagnosed as PET two years before and had been treated by insertion of a silicone plug (Kobayashi plug) at the other hospital...

The role of the immune system in mediating cochleovestibular pathologies has received increasing attention in recent years. Autoimmune vertigo may be an invalidating condition and may worsen the quality of life of affected patients, especially in the cases of delayed diagnosis. Since the etiopathogenesis is still not clear, also the treatment is not yet completely delineated. According to the clinical presentation, autoimmune vertigo can present as an isolated disorder or in association with systemic autoimmune diseases...

Enlarged vestibular aqueduct (EVA) is an inner ear malformation associated with sensorineural hearing impairment. The majority of EVA are associated with Pendred syndrome and non-syndromic DFNB4, two autosomal recessive disorders caused by mutations in SLC26A4. However, a significant percentage of EVA patients cannot have confirmed diagnosis by screening common SLC26A4 mutations, constituting an enigma in genetic diagnosis. To enable comprehensive genetic examination and explore the etiologies of EVA, we designed a next-generation sequencing panel targeting the entire length of three Pendred syndrome/DFNB4 genes (SLC26A4, FOXI1, and KCNJ10) and exons of 10 other genes related to EVA, and performed genetic testing in 50 EVA families without confirmative results on screening for SLC26A4 hotspots (c...

Perception of verticality is required for normal daily function, yet the typical human detection error range has not been well characterized. Vertical misperception has been correlated with poor postural control and functionality in patients after stroke and after vestibular disorders. Until now, all the published studies that assessed Subjective Postural Vertical (SPV) in the seated position used small groups to establish a reference value. However, this sample size does not represent the healthy population for comparison with conditions resulting in pathological vertical...

OBJECTIVE: Benign paroxysmal positional vertigo (BPPV) is the most frequent peripheral vestibular disorder and is particularly seen among older patients suffering from vertigo. The brief vertigo attacks in and imbalance symptoms of BPPV are caused by freely floating otoconia within the semicircular canals. The aim of this prospective study was to evaluate the role of oxidative stress, using native thiol/disulfide (SH/SS) homeostasis as a novel indicator, in the etiology of BPPV. MATERIALS AND METHODS: The 62 participants in the study included 31 patients with BPPV and, as the control group, 31 healthy individuals without any cochleovestibular disorders...

As a neurodegenerative movement disorder, Parkinson's disease (PD) is commonly characterized by motor symptoms such as resting tremor, rigidity, bradykinesia, and balance and postural impairments. While the main cause of PD is still not clear, it is shown that the basal ganglia loop, which has a role in adjusting a planned movement execution through fine motor control, is altered during this disease and contributes toward the manifested motor symptoms. Galvanic vestibular stimulation (GVS) is a non-invasive technique to influence the vestibular system and stimulate the motor system...
