Tinnitus is the perception or sensation of sound in the absence of an external physical stimulus, thought to affect around 10% of adults in the UK. The impact of tinnitus in an individual can range from minimal to extremely invasive and can negatively impact a person’s quality of life. Currently the exact aetiology of tinnitus is unknown; however maladaptive plasticity due to sensorineural hearing loss is thought to play a big role. Neuroimaging studies have pointed to overactivation or excessive spontaneous activity within the central auditory cortex. Furthermore, electrophysiological techniques have confirmed the frontal cortex’s role tinnitus through dysfunctional top-down modulation.
Transcranial direct current stimulation (tDCS) is a neurostimulation technique in which small currents (1-2mA’s) are delivered to the brain, thereby depolarising or hyperpolarising neurons within the desired region of cortex. tDCS is a non-invasive and easy to apply tool, delivered by applying two surface electrode to a patients head. It has previously been used as a treatment for depression, stroke rehabilitation and cognitive enhancement. Some studies have even pointed out the potential benefit of tDCS in tinnitus patients, but this has not yet been investigated within the UK.
The goal of the project is to optimise tDCS stimulation parameters for the treatment of tinnitus and explore feasibility and efficacy of tDCS in people with tinnitus. Both subjective (i.e. self-reported tinnitus handicap, depression and anxiety) and objective (changes in the oscillatory brain activity before, after and potentially during the intervention) measures will be collected. This will be the first study in the UK investigating the effects of tDCS on tinnitus.
The successful applicant will join a large and vibrant tinnitus research group and benefit from strong supervisory and peer support.
The stipend for this PhD is £15,000 per annum.
