Tourette syndrome (TS) is a developmental neurological disorder characterized by vocal and motor tics associated with cortical-striatal-thalamic-cortical circuit dysfunction, hyperexcitability within cortical areas, altered intracortical inhibition. TS often follows time course in which become increasingly more controlled during adolescence many individuals, who exhibit enhanced control over their volitional movements. Importantly, outputs appears to be brought about reduction the gain of...

Imbalances in glutamatergic (excitatory) and GABA (inhibitory) signalling within key brain networks are thought to underlie many mental health disorders, for this reason there is considerable interest investigating how individual variability localised concentrations of these molecules relate disorders. Magnetic resonance spectroscopy (MRS) provides a reliable means measuring, vivo, neurometabolites such as GABA, glutamate glutamine that can be correlated with function dysfunction. However,...

Tourette syndrome (TS) is a neurological disorder characterised by vocal and motor tics. It associated with cortical–striatal–thalamic–cortical circuit [CSTC] dysfunction hyper-excitability of cortical regions. TS follows developmental time course, in which tics often become increasingly more controlled during adolescence. Importantly, however, substantial minority patients continue to have debilitating into adulthood. This indicates that there may be important differences between adult...

Non-invasive methods, such as neurofeedback training, could support cognitive symptom management in Huntington's disease by targeting brain regions whose function is impaired. The aim of our single-blind, sham-controlled study was to collect rigorous evidence regarding the feasibility training examining two different activity and connectivity real-time functional MRI training. Thirty-two gene-carriers completed 16 runs using an optimized protocol. Participants were randomized into four...

Abstract Non-invasive methods, such as neurofeedback training (NFT), could support cognitive symptom management in Huntington’s disease (HD) by targeting brain regions whose function is impaired.

Abstract Background The telemedicine clinic in general surgery has become widespread since the onset of COVID-19 pandemic and remained so following relaxation restrictions on conventional face-to-face appointments. However, there been significant scepticism regarding its continued utility. In particular, is a concern that patients cannot be adequately assessed counselled for invasive procedures, which may result high cancellation rates day procedure. aim this study was to assess rate...

Gamma-aminobutyric acid (GABA) and glutamate are the primary neurotransmitters responsible for modulating excitatory inhibitory signalling within human brain. Dysfunctional GABAergic glutamatergic has been identified as a key factor in range of neuropsychiatric conditions; hence measurement modulation these neurometabolites is important improving our understanding conditions treatment options. Gabapentin (GBP) one several drugs developed to increase GABA levels routinely prescribed such...
