Active clinical trials for "Tinnitus"

In the present randomized waiting-list-controlled study the investigators examined a specific manualized mindfulness-based therapeutic approach in the treatment of chronic tinnitus.

The purpose of the study is the evaluation of the therapeutic benefit of intratympanic AM 101 injections in comparison to placebo in the treatment of persistent acute inner ear tinnitus following acute sensorineural hearing loss.

The purpose of this study is to develop and test a subject operated device to lessen tinnitus (ringing in the ear), based on subject-feedback for stimulus presentation.

participants will be randomized into one of three groups: 3-session CET intervention, 3-session ACT intervention, or Waiting List group. Each weekly session will last up to 2 hours and 10 participants will be assigned to each group. There will be two cohorts, with 30 participants in each cohort. The Waiting List group will receive the CET intervention after the groups have completed theirs.

Tinnitus is the perception of sound in the absence of corresponding external sound. Tinnitus affects approximately 10-15 % of the population. The prevalence increases with age and it is estimated that more than 20 % of the older people have tinnitus. Approximately 10-15 % of tinnitus patients have clinically relevant, disabling tinnitus causing for example anxiety, depression and sleep disturbances. The treatment of chronic tinnitus is difficult and most therapies focus on alleviating the condition rather than treating the cause. Pathophysiology of tinnitus still remains incompletely understood. Functional brain imaging data in tinnitus patients and animal models suggest that tinnitus is associated with increased neuronal activity, increased synchronicity, and functional reorganization within the auditory cortex either uni- or bilaterally, but there are also functional alterations in brain areas outside the auditory system. Transcranial magnetic stimulation (TMS) is a neuromodulation technique based on the principle of electromagnetic induction of an electric field in the brain by means of magnetic pulses given to the scalp. TMS is a non-invasive, painless, and safe method for modulation of cortical activity. TMS pulses given at low frequencies (≤ 1 Hz) have been shown to decrease cortical excitability both in experimental settings and humans, which forms the basis for using low frequency rTMS to treat chronic tinnitus patients, in whom hyperactivity of the auditory cortex has been observed in functional brain imaging studies

The purpose of this study is to investigate whether increased tinnitus reduction can be obtained with Deanxit in patients already receiving Rivotril.

The investigators propose to evaluate two different approaches to the alleviation of tinnitus symptoms by comparing changes from baseline performance on the Tinnitus Severity Index. They propose to provide an unbiased evaluation of competing methodologies. The design is one in which pairs of prospective subjects are randomly assigned to one of two treatment groups. Changes in group performance will be compared for selected measures.

This device-study includes a pilot, physiological investigation of normal human subjects. The aim is to determine how existing non-invasive neuromodulation devices affect brain circuitry as measured by EEG recording. Currently, the application of non-invasive neuromodulation is rarely guided by detailed knowledge of how neural activity is altered in the brain circuits that are targeted for intervention. This gap in knowledge is problematic for interpreting response variability, which is common. To address this gap, the current proposal aims to combine two forms of neuromodulation sequentially, transcranial direct current stimulation (tDCS) and repetitive transcranial magnetic stimulation (rTMS), to regulate homeostatic plasticity prior to rTMS delivery at different frequencies of rTMS. Homeostatic plasticity, the initial activation state of a targeted circuit, is a key determinant of whether rTMS induces long term potentiation (LTP) or long term depression (LTD) Yet, homeostatic plasticity is rarely measured or controlled in rTMS studies. We aim to control homeostatic plasticity by preconditioning the targeted circuits with tDCS prior to rTMS delivery. The protocol included an exploratory aim to examine physiological changes in patients with tinnitus but this aim was not part of the pilot physiological investigation and it could not be completed due to funding limitations.

The proposed research is to identify the brain areas activated or deactivated by tinnitus in humans. The identification of these areas is expected to be able to treat tinnitus refractory to traditional therapies by methods of brain stimulation. Furthermore, this technique would be very useful to verify the effectiveness of any treatment to relieve tinnitus. The brain activation measured during fMRI will be performed in a position of rest, after inhibition of tinnitus, and after application of a sound that does not inhibit tinnitus. This comparison will identify specific brain areas activated or deactivated by tinnitus.

The study is a double-blind study designed to evaluate the efficacy of deep transcranial magnetic stimulation (deep TMS) of the left auditory cortex using the HMCIPCC coil, in the treatment of patients with tinnitus
