Filter by:There is incidental evidence (casuistic findings) that the treatment with vardenafil of male patients suffering from erectile dysfunction and comorbid tinnitus experienced an improvement of their tinnitus. Randomized, parallel-group, double-blind, placebo-controlled trial over 16 weeks (12 weeks of treatment + 4 weeks follow-up) with 10 mg vardenafil BID p.o. in men and women with chronic tinnitus.
Caffeine intake is reported by many authors to enhance the perception of tinnitus. The aim of this study is to determine the effects of 1 month caffeine intake reduction in the scores of validated questionnaire Tinnitus Handicap Inventory (THI) and in a visual-analog scale (VAS).
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.
Tinnitus is defined as the perception of sound in the absence of a external source. About 15 % of the population is believed to experience tinnitus and for about 20 % of them it may become a very serious problem. Total comprehension of tinnitus pathophysiology has not yet been achieved, but modern theories focus in brain hyperactivity following inner ear damage, with involvement of various neurotransmitters. Piribedil,a dopamin agonist, has been used to treat tinnitus, focusing in dopamine release, which is inhibitory. Electrophysiological methods,like acoustic otoemissions and electrocochleography may reveal the changes in peripherical and central auditory pathways and help to choose the specific patients who could benefit from piribedil treatment.
A study on the effects of the FDA approved drug Modafinil upon attention problems associated with tinnitus. This is considered to be a safe drug with few side effects. Each subject will be asked to participate in 3 sessions each lasting approximately 1 hour in which cognitive testing and recordings will be taken. The study involves each subject taking a 2- week supply of Modafinil and a 2- week supply of placebo. We hypothesize inattention related to thalamocortical dysrhythmia found in tinnitus can be reduced by Modafinil thus improving vigilance.
Millions of Americans suffer from tinnitus. However, there is no widely accepted treatment that has been shown to be effective in controlled investigations. The purpose of this study is to evaluate the effectiveness of Tinnitus Retraining Therapy (TRT). This study will investigate the contributions of counseling, the use of hearing aids and sound generators, and the importance of setting masking noise to a particular level. All groups will receive the same Counseling. In pilot studies we have developed a picture-based counseling protocol. The results of this study will determine if TRT is more effective than masking or counseling alone.
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 purpose of this study is to determine wether Gabapentin which is useful for treating neuropathic pains, is effective on idiopathic subjective tinnitus.
Tinnitus, i.e., the perception of sounds or noise in the absence of auditory stimuli, is a frequent and often severely disabling symptom of different disorders of the auditory system. There are currently no causal treatments. Using repetitive transcranial magnetic stimulation (rTMS), we have previously demonstrated that the temporoparietal cortex is critically involved in tinnitus perception and that tinnitus can be reduced by rTMS applied to these cortical regions. Therefore, it is reasonable to test rTMS as a potential new treatment strategy against tinnitus. At this stage, small pilot studies indicate some effect on tinnitus impairment but the reduction is predominantly reported to be transient, with high interindividual variability, and questionable clinical relevance. Moreover, the optimal stimulation area is unclear. Here, we use theta burst stimulation (TBS), a new rTMS paradigm for the prolonged modulation of cortical activity. The aim of this study is to test safety and effectivity of 4 weeks of daily bilateral TBS to two cortical areas on chronic tinnitus compared to sham-stimulation.
The purpose of this study is to determine whether chronic electrical stimulation of the primary auditory cortex is effective in the treatment of chronic, severe and intractable tinnitus
