Journal ArticleDOI

TL;DR: In a prospective multicentre study involving 1280 patients with idiopathic RBD, Postuma et al. test the predictive power of 21 prodromal markers of neurodegeneration, providing a template for planning neuroprotective trials.
Journal ArticleDOI
Human cognition involves the dynamic integration of neural activity and neuromodulatory systems
James M. Shine,Michael Breakspear,Michael Breakspear,Peter T. Bell,Kaylena A. Ehgoetz Martens,Richard Shine,Richard Shine,Oluwasanmi Koyejo,Olaf Sporns,Russell A. Poldrack +9 more
TL;DR: It is found that neuronal activity converged onto a low-dimensional manifold that facilitates the execution of diverse task states and advance the understanding of functional brain organization by emphasizing the interface between neural activity, neuromodulatory systems, and cognitive function.
Journal ArticleDOI
Does anxiety cause freezing of gait in Parkinson's disease?
TL;DR: There is strong evidence that anxiety is an important mechanism underlying freezing of gait and the notion that the limbic system may have a profound contribution to freezing in PD is supported.
Journal ArticleDOI
The functional network signature of heterogeneity in freezing of gait.
Kaylena A. Ehgoetz Martens,Julie M. Hall,Matthew J. Georgiades,Moran Gilat,Courtney C. Walton,Elie Matar,Simon J.G. Lewis,James M. Shine +7 more
TL;DR: The findings provide confirmatory evidence for systems-level impairments in the pathophysiology of freezing of gait and further advance the understanding of the whole-brain deficits that mediate symptom expression in Parkinson's disease.
Journal ArticleDOI
Dopamine depletion impairs gait automaticity by altering cortico-striatal and cerebellar processing in Parkinson's disease.
Moran Gilat,Peter T. Bell,Kaylena A. Ehgoetz Martens,Matthew J. Georgiades,Julie M. Hall,Courtney C. Walton,Simon J.G. Lewis,James M. Shine,James M. Shine +8 more
TL;DR: It is demonstrated that dopamine ameliorates gait automaticity in Parkinson's disease by altering striatal, limbic and cerebellar processing, thereby informing future therapeutic avenues for gait and falls prevention.
