Figure 4

Right/visuoperceptive variant Alzheimer's disease. A 64 year old man presenting with short-term memory loss and difficulty with visually guided tasks (reading clocks and music). Imaging done 3 years into the course of illness, including axial T1 MRI at the level of the midbrain (top left), demonstrated subtle right, greater than left, temporal and parietal atrophy with relative expansion of right lateral ventricle and increased right parietal sulcal markings (white arrows), less evident at the level of the basal ganglia (bottom left). At the same time, axial single-photon emission computed tomography (SPECT; right) demonstrated right hypoperfusion, particularly in the parietal region (red arrows). The patient died 5 years into the course of disease, and autopsy confirmed Alzheimer's disease (Braak V/VI).
