Note:—PC indicates posterior cingulate gyrus; Pari, parietal association cortex; Lat. Temp, lateral temporal cortex; Med. Temp, medial temporal cortex; Fron, frontal cortex; Occ, occipital cortex; SM, sensorimotor cortex; ST, striatum; TH, thalamus; BS, brain stem; AMY, amyloid deposition: 1) asymmetric reduction is characteristic, 2) frontal dominant metabolic reduction is often demonstrated in addition to infarction region; SD, semantic dementia; VaD, vascular dementia; ↓, decreased; →, preserved; +, positive; −, negative.
