Tinnitus

Fagelson, Marc A. 01 March 2019 (has links)
Book Summary: The SAGE Encyclopedia of Human Communication Sciences and Disorders is an in-depth encyclopedia aimed at students interested in interdisciplinary perspectives on human communication—both normal and disordered—across the lifespan. This timely and unique set will look at the spectrum of communication disorders, from causation and prevention to testing and assessment; through rehabilitation, intervention, and education. Examples of the interdisciplinary reach of this encyclopedia: A strong focus on health issues, with topics such as Asperger's syndrome, fetal alcohol syndrome, anatomy of the human larynx, dementia, etc.Including core psychology and cognitive sciences topics, such as social development, stigma, language acquisition, self-help groups, memory, depression, memory, Behaviorism, and cognitive developmentEducation is covered in topics such as cooperative learning, special education, classroom-based service delivery The editors have recruited top researchers and clinicians across multiple fields to contribute to approximately 640 signed entries across four volumes.

Temporäre Harmonisierung des monotonalen Tinnitus mittels transponierter Musik ‒ Smetana-Phänomen

Tymnik, Gerd, Spindler, Martin, Reiß, Jutta, Schlemmer, Tobias, Kuhlisch, Eberhard, Schönfelder, Gert, Lippmann, Matthias, Schmidt, Stefan, Weber, Gerhard, Finger, Adolf 19 January 2018 (has links)
Ein neuer Ansatz zur Linderung von chronisch-dekompensiertem Tinnitus mit monotonalem Charakter wird vorgestellt. Mithilfe von transponierter Musik wird der monotonale Tinnitus gezielt in ein wohlklingendes (harmonisches) Klangerlebnis eingebettet und damit dem Betroffenen das Defokussieren des Dauertons erleichtert. Das Verfahren wurde softwarebasiert umgesetzt und in einer Untersuchungsreihe mit Patienten auf seine Wirksamkeit überprüft. Dabei konnte insbesondere ein Sofort-Effekt unter der angepassten Musik herausgestellt werden, welcher das Intensitätsempfinden des Tinnitus drastisch senkt.

The Association Between Tinnitus and Posttraumatic Stress Disorder

Fagelson, Marc A. 01 December 2007 (has links)
Purpose: Posttraumatic stress disorder (PTSD) affects nearly 10% of the population, a prevalence comparable with that of tinnitus. Similarities between the way PTSD and tinnitus influence auditory behaviors include exaggerated startle responses and decreased loudness tolerance. Tinnitus loudness is often exacerbated by sounds that trigger PTSD-related anxiety. This report addresses physical and psychological relations between PTSD and tinnitus. Method: A chart review of veterans seen over a 4-year period for tinnitus services was conducted. Case history and self-assessments of tinnitus handicap were examined in all patients. A review of the literature related to triggers and effects of PTSD was conducted to explore potential consequences related to the presence of PTSD in the Veterans Affairs Medical Center (VAMC) tinnitus population. Results: Chart review confirmed that 34% of the first 300 patients enrolled in the VAMC Tinnitus Clinic also carried a diagnosis of PTSD. Patient reports citing tinnitus severity, suddenness of tinnitus onset, sound-tolerance problems, and sound-triggered exacerbation of tinnitus were more common for patients with a PTSD diagnosis than patients with tinnitus only. Conclusions: Several neural mechanisms linked to both tinnitus and PTSD affect auditory behaviors. Audiologists should be aware that patients with tinnitus and PTSD will require test protocols and referrals that address these powerful responses.

Tinnitus-related hyperactivity through homeostatic plasticity in the auditory pathway

Schaette, Roland 25 April 2008 (has links)
Tinnitus, die Wahrnehmung eines Phantomgeräuschs, geht in den meisten Fällen mit Hörverlust einher. Es ist jedoch unbekannt, wie Hörverlust zu Tinnitus führen könnte. In Tierversuchen wurde gezeigt, dass Verhaltensanzeichen für Tinnitus nach Hörverlust mit erhöhten spontanen Feuerraten von Neuronen im zentralen auditorischen System korreliert sind. Zunächst untersuchen wir ob sich bei lärmbedingtem Hörverlust die Audiogramme von Patienten mit und ohne Tinnitus unterscheiden. Im Vergleich zu Patienten ohne Tinnitus haben Tinnituspatienten im Mittel weniger Hörverlust, einen steileren Abfall des Audiogramms, und die Audiogrammkante befindet sich bei höheren Frequenzen. Mit einem theoretischen Modell zeigen wir, wie tinnitusartige Hyperaktivität durch eine Stabilisierung der mittleren Feuerrate von Neuronen im zentralen Hörsystem mittels homöostatischer Plastizität entstehen kann: verringerte Aktivität von Hörnervfasern nach Hörverlust wird kompensiert durch eine Erhöhung der neuronalen Verstärkung. Dies stabilisiert die mittlere Rate, kann jedoch zu einer Erhöhung der spontanen Feuerraten führen, die dann von Art und Stärke der cochlearen Schädigung abhängen. Wir testen das Modell, indem wir es auf die Audiogramme von Patienten mit tonalem Tinnitus und Lärmschwerhörigkeit anwenden. Für jedes Audiogramm sagen wir mit dem Modell Veränderungen in der Spontanaktivität von auditorischen Neuronen vorher. Das resultierende Hyperaktivitätsmuster hat typischerweise eine deutliche Spitze, die mit einem steilen Abfall des Audiogramms einhergeht. Wenn solch eine Spitze als Grundlage für einen tonalen Tinnitus interpretiert wird, dann sagt das Modell Tinnitusfrequenzen nahe den empfundenen Tinnitustonhöhen vorher. Unser Modell stellt also eine plausible Hypothese, wie Hörverlust zu Tinnitus führen könnte, dar. Basierend auf dem Modell zeigen wir außerdem wie Hyperaktivität und somit eventuell auch Tinnitus, durch zusätzliche akustische Stimulation reduziert werden könnte. / Tinnitus is a phantom auditory sensation that is associated with hearing loss, but how hearing loss can lead to tinnitus has remained unclear. In animals, hearing loss through cochlear damage can lead to behavioral signs of tinnitus and can increase the spontaneous firing rates of central auditory neurons. To study the relation between hearing loss and tinnitus, we first analyze audiometric differences between patients with hearing loss and tinnitus and patients with hearing loss but without tinnitus. We find that tinnitus patients have on average less hearing loss, a steeper slope of the audiogram, and the audiogram edge is located at higher frequencies compared to patients without tinnitus. We then derive a computational model that demonstrates how tinnitus-related hyperactivity could arise as a consequence of a stabilization of the mean firing rates of central auditory neurons through homeostatic plasticity: decreased auditory nerve activity after hearing loss is counteracted through an increase of the neuronal response gain. This restores the mean rate, but can also lead to increased spontaneous firing rates, which depend on the type and degree of cochlear damage. Finally, we test the ability of our model to predict tinnitus pitch by applying it to audiograms from patients with noise-induced hearing loss and tone-like tinnitus. Given an audiogram, the model is used to predict changes in the spontaneous firing rates of central auditory neurons. The resulting hyperactivity pattern typically exhibits a distinct peak that is associated with a steep drop in the audiogram. If such a peak is interpreted as the basis for a tone-like tinnitus sensation, the model predicts a tinnitus frequency that is close to the patient''s tinnitus pitch. Thus, our model presents a plausible hypothesis of how hearing loss could lead to tinnitus. Based on this model, we also show how hyperactivity, and possibly also tinnitus, could be alleviated through additional acoustic stimulation.
