Filter by:The purpose of this research study is to determine whether the Brain Fitness Program-Tinnitus affects how tinnitus is perceived and if its use aids in the recovery of cognitive functions that may be affected by tinnitus. The investigators hope to better understand areas of the brain involved with or changed because of tinnitus. The investigators also hope to see if the Brain Fitness Program-Tinnitus impacts changes in those areas of the brain the investigators believe may be affected by tinnitus.
Confirmation of efficacy and safety of acoustic CR®-neuromodulation for the treatment of chronic tinnitus patients using the CE marked ANM T30 CR®-system in a real life outpatient setting. - Identification of early indicators for therapy success - Comparison of different patient groups regarding: tinnitus severity, tinnitus duration, level of hearing loss, stimulation patterns, unilateral monotonal vs. all other complex forms - Representative set of safety data in a broad patient spectrum - Measurement of tinnitus burden (TBF-12 Questionnaire) - Generation of longterm compliance data
The objective of the investigators study is to assess conventional repetitive transcranial magnetic stimulation (rTMS) in patients with chronic severe tinnitus. A randomized, double-blind, sham-controlled procedure, with four increasing levels of magnetic "pseudo-dose" has been designed, in order to characterize the effectiveness of rTMS while controlling its safety and tolerability. By combining various rTMS protocols with a twelve-month follow-up, and using an effect modeling, the study aims at: (i) specify the effective values of rTMS parameters, with an adequate tolerance; (ii) determine the expected benefit and the persistence of effect; (iii) assess the practical feasibility of this kind of therapeutic management.
Tinnitus, commonly referred to as "ringing in the ears", affects 50 million people in the United States and is recognized as a major public health concern. Tinnitus is the most frequent cause of service-connected disability claims among war veterans. Tinnitus remains a subjectively diagnosed entity. There is no standardized objective method of diagnosing tinnitus or describing the functional impact of the condition. Currently, physicians have to rely on patient-based self reports. Without an objective method of diagnosing tinnitus and describing the functional implications, adequate treatment delivery is also hampered since there is no way to objectively stratify patients into severity groups and assess response to treatment. Because tinnitus is known to negatively affect cognition through the ventral attention networks and the prefrontal cortex, measuring cognitive processing speed is a possible way to objectively measure tinnitus. This study builds on previous work the investigators have done that utilized a quick, easily accessible measure of auditory processing speed. That earlier study showed a correlation between that measure and self reported measures of tinnitus severity, and this study attempts determine a more precise estimate of that correlation. It also better validates those results by including a traditional neurocognitive measuring cognitive speed and by controlling for the presence of depression and somatoform disorders.
1. Overview of tinnitus Tinnitus is a noisy sound which is perceived without any external sound source. According to the survey of the US, 10-20% of adult have the symptom of tinnitus and 3-5% of tinnitus patients have severe discomfort of daily life. Severe tinnitus can result in psychiatric problems such as depression and anxiety disorders. Enhancement of environmental sound, hearing aids, sound generators, cognitive therapy, transcranial magnetic therapy, and drug therapy have been tried for treatment of tinnitus. Nitric oxide(NO) is a well-known neurotransmitter acting as a vasodilator through regulation of production of cyclic guanosine monophosphate(cGMP) and can be found in various sites of cochlea. It is reported that cGMP enhances activity of protein kinase A (PKA), a mediator of platelet aggregation inhibition and vasodilatation and results in increase of vascular flow. 2. Characteristics of the clinical research drug, cilostazol Cilostazol inhibits phosphodiesterase type 3 (PDE3) selectively and increases amount of cAMP by inhibition of degradation of cyclic adenosine monophosphate(cAMP). cAMP again by increasing the active form of PKA suppress the production of blood clots and increase blood flow by expanding blood vessels. Anti-platelet activity and vasodilatation effect of cilostazol have been used for improvement of diabetic peripheral vascular disorders and suppression of stroke recurrence. Previous studies reported that by increasing the activity of NO and PKA, the blood flow of stria vascularis and cochlear hair cells can be improved. These studies implies that cilostazol, which causes inhibition of PDE3 and increase of PKA, can have a potential effect on improvement of tinnitus by increase of blood flow to peripheral cochlear cells. Thus, we hypothesized that cilostazol, which has been widely used for enhancing peripheral blood flow, can bring improvement of tinnitus by causing better peripheral blood flow of cochlea. 3. The aim of the study We planned this study to validate the assumptions of the background. The aim of our study is whether administration of cilostazol can improve tinnitus in terms of subjective degree of symptoms in chronic tinnitus patients.
This study will assess the efficacy of a two week treatment with BGG492 in patients with chronic subjective Tinnitus.
The investigators hypothesize that individual differences exist in resting-state cortical attention, control, sensory, and emotion networks prior to noise exposure and these differences predispose some to the development of bothersome tinnitus. Furthermore, the investigators hypothesize that these changes in functional connectivity of these vulnerable systems after noise exposure are responsible for tinnitus. The proposed study will use a case-control cohort study design. Cases will be those soldiers who develop tinnitus and controls will be those who do not. This will be the first prospective study of tinnitus and will provide important information about the neurobiology of tinnitus. If a cortical neural network etiology for bothersome tinnitus is confirmed, it will be an astounding, powerful, paradigm shifting model for the diagnosis, prevention and, most importantly, treatment of tinnitus. Furthermore, if a battery of neurocognitive tests can identify soldiers at risk for the development of tinnitus then appropriate primary prevention strategies can be introduced. There are three Specific Aims to this project. Specific Aim 1. To determine if soldiers who develop tinnitus display pre-deployment differences in a set of physical, functional, cognitive, vulnerability, perpetuating factors, pre-deployment neurocognitive scores, or neuroimaging features compared to soldiers who do not develop tinnitus ("control group"). Specific Aim 2. To determine if particular scores on neurocognitive tests or neuroimaging features of functional/structural connectivity networks are associated with the development of tinnitus. Specific Aim 3. To identify a set of pre-deployment physical, functional, cognitive, vulnerability, and perpetuating factors, neurocognitive responses, and neuroimaging features that are associated with the development of tinnitus. The investigators plan to recruit 200 soldiers, between the ages of 18 and 30 years who do not have hearing loss or tinnitus and have never been deployed to military theater. The soldier participants will undergo a variety of tests before and after deployment, which will include a hearing test, neurocognitive tests (i.e., brain function tests), and a variety of novel radiologic imaging studies of the brain. One of these novel radiologic imaging studies is functional connectivity Magnetic Resonance Imaging, a proven methodology that monitors changes in brain activity and connections based on blood flow between different brain areas and levels of consumption of oxygen. This information is used to describe the condition of important neural networks responsible for such things as attention, mood, sensation, vision, hearing, and introspection or self-contemplation.
