Alzheimer’s Disease and Parkinson’s Disease with Dementia: Comparison of Cortical Blood Flow Demonstrated by Three-Dimensional Surface Display
Cognitive impairment is a well recognized feature of patients with Parkinson’s disease as well as Alzheimer’s distice. Although the pattern of cognitive dysfunction is not identical, the two diseases share many neuropathological1 and neurochemical2 features. This study was conducted to compare the brain perfusion image using three-dimensional surface (3D) display in Parkinson’s disease with that in Alzheimer’s disease. 3D surface display may be superior to tomographic images for diagnosing the extent of cerebral cortical hypoperfusion,3 since the physician must integrate information from a large number of single photon emission computed tomography (SPECT) images to evaluate low perfusion lesions stereoscopically.
