SPECT studies of the brain were performed with some reduction in image quality noted due to patient movement. The studies show focal hypoperfusion in the prefrontal lobes and in the opercular regions are superficial to the insula. Posterior cingulate and precuneus perfusion appears preserved without diagnostic features of Alzheimer's disease. Very small foci of posterior parietal hypoperfusion may be consistent with trauma or vascular disease. The anterior temporal lobes are well-perfused as are the basal ganglia and the cerebellum. Neurostat analysis also performed confirms the impression of free frontal and opercular hypoperfusion with the prominent enlarged lateral ventricles also being delineated. The studies are highly suspicious of the frontal variant of frontotemporal dementia. There may also be a vascular component of dementia present and ventriculomegaly is confirmed.
