Functional correlates of vertical gaze palsy and other ocular motor deficits in PSP: An FDG-PET study
2014
Abstract Objective To determine the functional correlates of vertical gaze palsy and other ocular motor deficits in patients with progressive supranuclear palsy (PSP) using [ 18 F]fluorodeoxyglucose (FDG-)PET. Methods Twenty-six patients with PSP underwent clinical examination of vertical gaze combined with FDG-PET scans to assess regional cerebral glucose metabolism as a marker of neuronal activity. Of these, eighteen PSP patients were also investigated by electrical nystagmography to determine horizontal ocular motor deficits. Statistical parametric mapping analyses were performed to correlate regional neuronal activity with ocular motor functions. Results In categorical comparisons, pati…
Neuronal Correlates of Clinical Asymmetry in Progressive Supranuclear Palsy
2014
Progressive supranuclear palsy (PSP) is characterized by a symmetric hypokinetic syndrome with early falls and vertical supranuclear gaze palsy. However, clinically asymmetric manifestations occur, resembling idiopathic Parkinson disease or corticobasal degeneration. The aim of this study was to determine the neuronal correlates of patients suffering from PSP with a lateralized disease manifestation (hemi-PSP) in comparison to patients with symmetric clinical presentation (symPSP) and corticobasal degeneration.Twenty-three patients with PSP and 8 patients with corticobasal degeneration according to standard diagnostic criteria underwent F-fluorodeoxyglucose (FDG) PET scans to assess disease…
