About us

Our research into the pathophysiology of Tourette syndrome and tic disorders dates back nearly two decades. During that time we have primarily used behavioural and state-of-the-art brain imaging and brain stimulation techniques to investigate: the neural processes that give rise to tics; the brain correlates of premonitory urges; and mechanisms of brain plasticity that might lead to the control or reduction of tics. This work was made possible and supported financially by a number of organisations and charities including: the UK Medical Research Council; Tourettes Action; the Tourette Association of America; and The National Institute of Health Research.

Improving the lives of people with Tourette Syndrome through better management of tics

An important focus of our research over the last few years has been to understand how the brain networks that give rise to tics could be effectively modified or controlled using non-invasive forms of brain stimulation so as to bring about a reduction in tics. 

The Neupulse
Journey

Our research on Tourette syndrome dates from 2005, when Georgina Jackson and colleagues began investigating mechanisms of cognitive control (over tics) (e.g., Mueller et al., 2006), and shortly thereafter Stephen Jackson began using multi-modal brain imaging and brain stimulation techniques to investigate brain network function in Tourette syndrome, including neuroplastic alterations in brain structure, function, and chemistry that might be responsible for the remission of tics in Tourette syndrome (e.g., Jackson et al., 2011; Draper et al., 2014; Draper et al., 2015; Draper et al., 2016).

Early on in our studies of Tourette syndrome we began a very useful collaboration with the UK charity Tourettes Action, and in 2009 Georgina Jackson was commissioned by Tourettes Action to examine the psycho-social experiences of young people with Tourette syndrome. During this study it became apparent that there is a considerable unmet need for effective therapies for Tourette syndrome, and in particular for safe and effective non-drug therapies that can be used by the individual outside of the clinic (i.e., in their home or in a school environment). This led us to begin a programme of studies that investigated how non-invasive brain stimulation techniques might be used to modulate brain network function, and whether this approach could be used to bring about therapeutic benefits in Tourette syndrome (e.g., remission of tics and co-occurring clinical phenomena).

One promising line of research focused on using non-invasive brain stimulation to modulate brain network function in Tourette syndrome through the mechanism of ‘entrainment’. As noted above, brain network function is associated with intrinsic oscillatory activity within the brain (brain rhythms) and many brain health conditions have been associated with alterations in brain oscillatory activity. Non-invasive brain stimulation techniques can be used to entrain oscillatory activity over targeted brain areas, and we hypothesised that ‘entraining’ those brain oscillations linked with movement suppression could be used to effectively reduce the occurrence of tics in Tourette syndrome.

However, brain stimulation techniques such as transcranial magnetic stimulation are not suitable for use outside of the clinic or for use with very young children, so we investigated alternative mechanisms for entraining brain network function using rhythmic peripheral nerve stimulation. This line of research, funded by the University of Nottingham, Tourettes Action, and the NIHR Nottingham Biomedical Research Centre, led to the development of the therapeutic approach described in our recent papers (Houlgreave et al., 2020; Morera-Maiquez et al., 2020) which forms the basis for the approach taken by Neurotherapeutics Ltd.

Building on the previous research and collaborations, we embarked on a pivotal clinical trial to evaluate the effectiveness of this novel approach, for alleviating the symptoms of Tourette syndrome. This UK-wide double-blind sham-controlled trial demonstrated encouraging results in a home-based study. Participants receiving active stimulation reported a substantial reduction in the severity and frequency of their tics (Maiquez, B. M. et al., 2023).

This trial marks a significant step towards developing a safe, effective, non-drug treatment for Tourette syndrome that individuals could administer independently outside clinical settings.

At Neupulse, we are not just developing a medical device; we are pioneering a change in the Tourette syndrome therapeutic landscape. Our commercial strategy is focused on bringing this ground-breaking technology from the realm of clinical trials into the hands of those who need it most.
