OBJECTIVE This systematic review describes the current functional neuroimaging literature in delirium, discusses pathophysiological implications of these results and highlights areas for further study. METHODS In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, an extensive search of medical databases was(More)
Delirium is a common, serious, yet poorly understood syndrome. Growing evidence suggests cerebral metabolism is fundamentally disturbed; however, it has not been investigated using 2-18F-fluoro-2-deoxyglucose (FDG) positron emission tomography (PET) in delirium. This prospective study thus explored FDG PET patterns of cerebral glucose metabolism in older(More)
Dystonia is a hyperkinetic movement disorder that can be highly stigmatizing and disabling. Substantial evidence from animal models, neuropathological, neurophysiological, neuroimaging and clinical studies emphasizes the role of dopaminergic dysfunction in the pathophysiology of dystonia, illustrating possible pathophysiological overlap with parkinsonism.(More)
