Abstract
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 database. Compared to age-matched controls, there were multiple hypoperfusion areas in cases where the original diagnosis was PD. Temporal bases showed the lowest perfusion; frontal bases and medial parietal lobes the second; visual cortices the third; and parietal association areas exhibited the fourth lowest. During the clinical course, 10 of the patients suffered dementia, 9 had fluctuating cognition, and 19 experienced repeated visual hallucinations. Significant negative correlations were observed between dementia and the bilateral posterior cingulate area, and among fluctuating cognition and bilateral medial parietal lobes, parietal association areas, and dorsal occipital lobes. Repeated visual hallucinations did not show any correlation with any region of interest. We concluded that multiple hypoperfusion areas were observed in the 3D-SSP SPECT analysis. Although the presence of dementia showed a significant relationship with the bilateral posterior cingulate areas, perfusion in the frontal bases, temporal bases, or parietal lobes was markedly more reduced than that seen in the bilateral posterior cingulate areas.

<EA>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 database. Compared to age-matched controls, there were multiple hypoperfusion areas in cases where the original diagnosis was PD. Temporal bases showed the lowest perfusion; frontal bases and medial parietal lobes the second; visual cortices the third; and parietal association areas exhibited the fourth lowest. During the clinical course, 10 of the patients suffered dementia, 9 had fluctuating cognition, and 19 experienced repeated visual hallucinations. Significant negative correlations were observed between dementia and the bilateral posterior cingulate area, and among fluctuating cognition and bilateral medial parietal lobes, parietal association areas, and dorsal occipital lobes. Repeated visual hallucinations did not show any correlation with any region of interest. We concluded that multiple hypoperfusion areas were observed in the 3D-SSP SPECT analysis. Although the presence of dementia showed a significant relationship with the bilateral posterior cingulate areas, perfusion in the frontal bases, temporal bases, or parietal lobes was markedly more reduced than that seen in the bilateral posterior cingulate areas.</EA>
