Learning how to change your own brain activity to reduce tinnitus
The ringing or hissing in the ears experienced during tinnitus can be debilitating. Although sometimes caused by problems in the ear, research suggests that tinnitus can frequently originate in the auditory cortex – the part of the brain responsible for processing sound.
There is currently no cure for tinnitus. The current gold standard treatment, cognitive behavioral therapy (CBT), is one of the methods that has proven most effective in reducing tinnitus-related stress and other psychological symptoms.
The Wyss Center is collaborating with researchers and clinicians at École Polytechnique Fédérale de Lausanne (EPFL) and Hôpitaux Universitaires de Genève (HUG) to investigate whether neurofeedback - the process of self-regulating brain activity - can help control tinnitus. By understanding whether it is possible for people with tinnitus to reduce the intensity of the noise they experience by learning how to alter their brain activity, the Neurotin team hopes to develop different strategies for neurofeedback and compare these novel approaches with CBT.
Under the supervision of principal investigator Prof. Dr. Pascal Senn, HUG, the Wyss Center is supporting a clinical trial to compare tinnitus reduction after three different approaches:
- Neurofeedback with electroencephalography (EEG)
- Neurofeedback with functional magnetic resonance imaging (fMRI)
Only participants whose tinnitus originates in the brain may take part in the trial.
Brain activity is monitored during neurofeedback sessions either using a cap with EEG sensors or an MRI scanner. The participants see their brain activity on a screen, in real time, so that they can learn to regulate the activity of their auditory cortex. If the participants successfully learn the technique it is hoped that they will eventually be able to use it to manage and even reduce their tinnitus.
If you are interested in participating in this research, or would like further information, please contact us in English or French via NeuroTin@protonmail.ch.
Participants must live within one hour of Geneva, Switzerland and be willing to travel once a week for several months.
