Active clinical trials for "Tinnitus"

This multi-site study evaluated the implementation of Progressive Tinnitus Management (PTM), which combines both Audiology and Psychology approaches to Tinnitus Management. Those Veterans who require intervention for tinnitus have different levels of need, and this progressive approach gives them the appropriate level of intervention.

The purpose of this study is to investigate the safety and efficacy of neramexane mesylate in the treatment of subjective tinnitus in comparison to placebo.

Test of hypothesis that in contrast to non-treatment tinnitus specific cognitive behavioral therapy intervention procedures that are manualized and structured within the disease management program TCP are effective.

The objective of this project is to determine whether acamprosate is more effective at providing relief for tinnitus than a placebo. Acamprosate has been suggested to be effective in reducing tinnitus annoyance in a preliminary study. Study evidence indicates that tinnitus is related to increased excitatory spontaneous brain activities. Acamprosate may help restore the excitatory/inhibitory balance in the brain and thus reduce tinnitus. The current study includes three phases. The first phase is an open-label screening study used to identify tinnitus subjects responding to acamprosate. These responding subjects will enter the second phase, which is a double blind, placebo-controlled study aimed at confirming the subjects' responses to acamprosate. In the third phase, clinical parameters of both responders and non-responders will be compared using a multi-linear regression model to determine characteristics that define the sub-group of tinnitus patients that are likely to benefit from acamprosate treatment. Participation in the study requires that individuals come to Portland, Oregon at least 6 times over 16 months for evaluation and data collection.

The goal of this trial to see if repetitive transcranial magnetic stimulation (rTMS) to the hearing area of the brain can lessen the perception of tinnitus. rTMS uses a strong magnet and when placed against the scalp generates a small electrical field within the brain. Depending on the frequency of the stimulation, this electrical field can either decrease or increase the electrical excitability of the brain. In this study, low-frequency stimulation will be used, which is thought to decrease nerve activity. It is this electrical excitability of the brain that is thought to be responsible for tinnitus. The hypothesis of this study is that rTMS can decrease the perception of tinnitus.

The study aims to develop and to evaluate a psychophysiological intervention for distressing chronic tinnitus. Therefore 100 people suffering from chronic tinnitus are randomly assigned to either an intervention-group, receiving 12 sessions of a psychophysiological oriented intervention, or to a waiting-list-group, who are waiting for a comparable time period. Afterwards, patients of the waiting-list-group also receive intervention. The effects of the intervention on severity, distress and perceived loudness of the tinnitus as well as on other psychological variables like depression or self-efficacy are evaluated through comparing the results of the intervention group with those of the waiting-list-group. Additionally the psychophysiological reactivity under different stress-conditions is measured before and after intervention or waiting. Therefore the activity of the muscles of head and shoulders (EMG) as well as the skin temperature and skin conductance are measured. It is hypothesized that patients with stronger psychophysiological reactivity benefit more from an psychophysiological intervention.

Tinnitus is commonly referred to as "ringing of the ears" - the perception of sounds in the absence of an external source of acoustic signals. Tinnitus may represent a severe disease and symptoms include depression, sleeping difficulties, decreased sound tolerance and hearing loss. One hypothesis is that tinnitus is caused by an increased activity of NMDA glutamate and dysfunctional alpha9/alpha10 acetylcholine receptors in the inner ear and central nervous system. Neramexane may alleviate tinnitus symptoms due to its NMDA and alpha9/alpha10 nACh receptor blocking activity. The purpose of this study is to assess the safety and efficacy of Neramexane compared with placebo in patients with subjective tinnitus.

The aim of the AURACCO study is to evaluate the association between the onset of tinnitus and hearing loss in patients with locally advanced head and neck cancer treated by concomitant chemoradiotherapy or exclusive radiotherapy

This study seeks to pilot an evaluation of whether an external jugular vein compression collar approved by the FDA for contact sports can provide symptomatic relief of venous pulsatile tinnitus. Furthermore, the study will evaluate quality of life impacts of the device and adherence by users.

Rationale: Tinnitus is the perception of sound without an external source. In the past decade, inflammation has been implicated in the pathophysiology of tinnitus. In animal models of tinnitus, the expression of proinflammatory cytokines Tumor Necrosis Factor-α (TNF-α) and interleukine-1β (IL-1β) was increased throughout the whole auditory tract. Only two studies evaluated cytokine concentrations in tinnitus patients. In these studies an increase of IL-6 and decrease of IL-10 have been objectified. However, studies did not include tinnitus patients based on the degree of hearing loss, despite that inflammation has also been implicated in hearing loss. On the other hand, studies about inflammation in hearing loss did not (always) exclude tinnitus. Thus, it remains unclear whether the upregulated cytokine concentrations the studies are specific for tinnitus, and whether potential effects remained unsignificant because the presence of hearing loss is a confounder. Therefore, the aim of this study is to evaluate the presence of inflammation in tinnitus patients with normal hearing. Objective: The main objective is to evaluate the presence of inflammation in blood samples of human subjects with tinnitus and normal hearing, compared to healthy controls. The secondary objective is to evaluate the relation between tinnitus severity and inflammatory marker concentrations. Study design: This is a cross-sectional study. Study population: Patients who have been referred to the tinnitus consultation at the outpatient clinic will be asked to participate in this study. For the control group, healthy volunteers will be recruited. Main study parameters/endpoints: The main study parameter is the disparity in blood cytokine levels between participants with and without tinnitus. Secondary study parameters are the relation between tinnitus severity and blood cytokine concentration, and the difference in complete blood count measures in participants with and without tinnitus.
