We investigated regional cerebral blood flow (rCBF) using three-dimensional stereotactic surface projection (3D-SSP) analysis in 30 patients initially diagnosed as Parkinson's disease (PD), and compared differences in rCBF between patients with and without PD-related manifestations. 3D-SSP analysis of cerebral perfusion was performed by use of a control(More)
Although dementia is increasingly recognized as a common feature in Parkinson's disease (PD), its pathological substrate remains unknown. We conducted cross-sectional and longitudinal brain perfusion SPECT analyses to explore changes during the course of developing dementia in PD.
