Dementia with Lewy bodies
Updates to Study Attributes
SPECT studies of the brain were performed following 99mTc ECD infusion with mental stimulation. Neurostat data analysis was applied.
These studies are of poor quality technically but do show reduced perfusion predominantly to the posterior aspect of both cerebral hemispheres cortices sparing the posterior cingulate and precuneus regions. There is only mild reduction of perfusion to the mid and anterior cerebral cortices.
Perfusion to the basal ganglia and brainstem and cerebellum appear normal.
Conclusion:
The findings are highly consistent with the diagnosis of Lewy's dementia showing posterior cerebral cortical hypoperfusion with retained posterior cingulate/precuneus perfusion..
