  • Vestibular Neuritis, Labyrinthitis, and a Few Comments Regarding Sudden Sensorineural Hearing Loss Marcello Cherchi
    Vestibular neuritis, labyrinthitis, and a few comments regarding sudden sensorineural hearing loss Marcello Cherchi §1: What are these diseases, how are they related, and what is their cause? §1.1: What is vestibular neuritis? Vestibular neuritis, also called vestibular neuronitis, was originally described by Margaret Ruth Dix and Charles Skinner Hallpike in 1952 (Dix and Hallpike 1952). It is currently suspected to be an inflammatory-mediated insult (damage) to the balance-related nerve (vestibular nerve) between the ear and the brain that manifests with abrupt-onset, severe dizziness that lasts days to weeks, and occasionally recurs. Although vestibular neuritis is usually regarded as a process affecting the vestibular nerve itself, damage restricted to the vestibule (balance components of the inner ear) would manifest clinically in a similar way, and might be termed “vestibulitis,” although that term is seldom applied (Izraeli, Rachmel et al. 1989). Thus, distinguishing between “vestibular neuritis” (inflammation of the vestibular nerve) and “vestibulitis” (inflammation of the balance-related components of the inner ear) would be difficult. §1.2: What is labyrinthitis? Labyrinthitis is currently suspected to be due to an inflammatory-mediated insult (damage) to both the “hearing component” (the cochlea) and the “balance component” (the semicircular canals and otolith organs) of the inner ear (labyrinth) itself. Labyrinthitis is sometimes also termed “vertigo with sudden hearing loss” (Pogson, Taylor et al. 2016, Kim, Choi et al. 2018) – and we will discuss sudden hearing loss further in a moment. Labyrinthitis usually manifests with severe dizziness (similar to vestibular neuritis) accompanied by ear symptoms on one side (typically hearing loss and tinnitus).

  • Clinical Policy: Central Auditory Processing Disorder Reference Number: HNCA.CP.MP.375 Effective Date: 10/07 Coding Implications Last Review Date: 3/21 Revision Log
    Clinical Policy: Central Auditory Processing Disorder Reference Number: HNCA.CP.MP.375 Effective Date: 10/07 Coding Implications Last Review Date: 3/21 Revision Log See Important Reminder at the end of this policy for important regulatory and legal information. Description Central auditory processing disorder (CAPD), also known as auditory processing disorder (APD), refers to the efficiency and effectiveness by which the central nervous system (CNS) utilizes auditory information in the perceptual processing of auditory information. The diagnosis, management, and even the existence of an auditory-specific perceptual deficit are controversial. Policy/Criteria I. It is the policy of Health Net of California that diagnostic testing and therapy for the management of central auditory processing disorder are considered investigational due to lack of scientific evidence to support the validity of any diagnostic tests and treatment. Background According to the American Speech-Language Hearing Association (ASHA), central auditory processing disorder (CAPD), also known as auditory processing disorder (APD), refers to difficulties in the perceptual processing of auditory information in the CNS as demonstrated by poor performance in one or more of the skills noted above. CAPD It is a complex and heterogeneous group of auditory-specific disorders usually associated with a range of listening and learning deficits. Children or adults suspected of CAPD may exhibit a variety of listening and related complaints such as difficulty understanding speech in noisy environments, following directions, and discriminating (or telling the difference between) similar-sounding speech sounds. The child may have difficulty with spelling, reading, and understanding information presented verbally in a classroom. Some individuals may also have behavioral, emotional or social difficulties.

  • DISORDERS of AUDITORY PROCESSING: EVIDENCE for MODULARITY in AUDITION Michael R
    DISORDERS OF AUDITORY PROCESSING: EVIDENCE FOR MODULARITY IN AUDITION Michael R. Polster and Sally B. Rose (Psychology Department, Victoria University of Wellington, Wellington, New Zealand) ABSTRACT This article examines four disorders of auditory processing that can result from selective brain damage (cortical deafness, pure word deafness, auditory agnosia and phonagnosia) in an effort to derive a plausible functional and neuroanatomical model of audition. The article begins by identifying three possible reasons why models of auditory processing have been slower to emerge than models of visual processing: neuroanatomical differences between the visual and auditory systems, terminological confusions relating to auditory processing disorders, and technical factors that have made auditory stimuli more difficult to study than visual stimuli. The four auditory disorders are then reviewed and current theories of auditory processing considered. Taken together, these disorders suggest a modular architecture analogous to models of visual processing that have been derived from studying neurological patients. Ideas for future research to test modular theory more fully are presented. Key words: auditory processing, modularity, review INTRODUCTION Neuropsychological investigations of patients suffering from brain damage have flourished in recent years and helped to produce more detailed and neuroanatomically plausible models of several aspects of cognitive function. For example, models of language processing are often closely aligned with studies of aphasia (e.g., Caplan, 1987; Goodglass, 1993) and models of memory draw heavily upon studies of amnesia (e.g., Schacter and Tulving, 1994; Squire, 1987). Most of this research has relied on visually presented materials, and as a result visual processing disorders tend to be more well-documented and better understood than their auditory counterparts.

  • Hearing Screening Result: Did Not Pass
    HEARING SCREENING RESULT: DID NOT PASS • The re-screening test is the only way to confirm if a baby has a potential hearing loss. • The American Academy of Pediatrics recommends hearing screens for all newborns. How Will My Baby’s Hearing Be Screened? Similar to the first hearing screen your baby had in the hospital or birthing center, the re-screening test is quick, painless, and most likely done while your baby is asleep. Soft sounds are played through earphones, and either: • microphones measure the echoes made by the ear called Otoacoustic Emissions (OAE) or • electrodes placed on the baby’s head measure the brain’s response using Automated Auditory Brainstem Response (AABR). What Does a “Did Not Pass” or “Referral” Result Mean? A “Did Not Pass” or “Referral” result means your baby needs You will receive the results of the screening before you leave the another hearing screen. This result does not mean your baby has hospital or doctor’s office. a hearing loss.

  • REVIEW Auditory Processing Disorder in Children
    Int. Adv. Otol. 2009; 5:(1) 104-115 REVIEW Auditory Processing Disorder in Children: Definition, Assessment and Management Sanem Sahli Department of Otorhinolaryngology, Head and Neck Surgery, Section of Audiology and Speech Pathology, Hacettepe University Faculty of Medicine, Ankara, Turkey Hearing is a complex process that is often taken for granted. As sounds strike the eardrum, the sounds (acoustic signals) begin to undergo a series of transformations through which the acoustic signals are changed into neural signals. These neural signals are then passed from the ear through complicated neural networks to various parts of the brain for additional analysis, and ultimately, recognition or comprehension. Auditory Processing Disorder (APD) previously known as “Central Auditory Processing Disorder” (CAPD) is a such disorder that auditory information is incorrectly processed in the brain. It is not a sensory hearing impairment; individuals with APD usually have normal peripheral hearing ability. APD is an umbrella term that describes a variety of problems with the brain that can interfere with processing auditory information. APD is assessed through the use of special tests designed to assess the various auditory functions of the brain. In APD, the approaches to remediation or management fall into three main categories: (1) enhancing the individual’s auditory perceptual skills, (2) enhancing the individual’s language and cognitive resources, and (3) improving the quality of the auditory signal Submitted : 22 August 2008 Revised : 11 December 2008 Accepted : 14 December 2008 Auditory processing disorder (APD), also known as may be reliant on or associated with intact central central auditory processing disorder (CAPD) is a term auditory function, they are considered higher order used to describe individuals with normal hearing who cognitive-communicative and/or language related have auditory-based receptive communication or functions and, thus, are not included in the definition [1] language problems.

  • Auditory Processing Disorder (APD): Identification and Accurate Diagnostic Procedures
    APD: Accurate Diagnosis 1 Running Head: APD Auditory Processing Disorder (APD): Identification and Accurate Diagnostic Procedures Yvonne McMahon May 19, 2011 APD: Accurate Diagnosis 2 Students who have difficulties with auditory processing tasks may be diagnosed with Auditory Processing Disorder (APD). However APD is not one of the 14 federal disability categories outlined in IDEA, therefore a student diagnosed solely with APD would not be eligible for an Individualized Educational Program (IEP). A student with APD would need to exhibit symptoms of one of the 14 qualifying disability categories and demonstrate a negative educational impact resulting from the disability (Virginia Department of Education, 2006). Because APD can exist in conjunction with attention deficit hyperactivity disorder (ADHD), a student exhibiting ADHD symptoms may qualify for an IEP under the category called Other Health Impairment (OHI) and receive modifications specific to ADHD. Unfortunately the student with both ADHD and APD might not receive special education services specific to underlying APD deficits and that may, consequently, have a negative impact on learning. According to Espy, Molfese, Molfese, & Modglin, (2004; as cited by Sharma, Purdy & Kelly, 2009), “There is objective evidence from a longitudinal study of 109 typically developing children for a link between early auditory processing and later reading ability” (p. 715). APD is a developmental disorder that may be responsible for a range of sensory processing deficits associated with learning difficulties (DeBonis & Moncrieff, 2008). Because APD may differ in severity from individual to individual and because APD may co-exist with other disabilities, it may be difficult to diagnose APD correctly (Dobrzanski-Palfery & Duff, 2007).
