Description of intervention(s) / exposure
Transcranial Magnetic Stimulation (TMS)
TMS will be performed on each participant including measures of
intracortical inhibition and facilitation, resting motor thresholds and motor evoked potentials before and after theta burst stimulation. The TMS protocol is expected to take 2-3 hours. In addition each participant will undergo standardised cognitive tests.

Summary
Brief summary
Transcranial Magnetic Stimulation is capable of inducing action potentials in cortical neurones, and provides the capacity to measure cortical neuronal excitability and interneuronal function. Preliminary data in previous studies shows this may be a method for measuring neuronal function in Progressive Supranuclear Palsy, which may enable its use as a biomarker. The intention of this study
is to determine if these measurements are able to distinguish PSP from other parkinsonian syndromes with similar clinical features,
ie. Multiple System Atrophy and Parkinson's Disease, and if these measurements correlate with markers of disease activity including cognitive changes. Results will also be compared with a group of healthy control participants to determine the reliability of these measurements.
