Averaged FDG-PET brain images of different types of dementia. The FDG-PET images have been z-scored to the mean and standard deviation of 111 cognitively healthy individuals that were included in the training set of MAD derivation in our previous study [44], then averaged within each dementia type. Undiff: Undifferentiated dementia; AD: Alzheimer’s disease; PCA: Posterior cortical atrophy; AAD: Atypical Alzheimer’s disease (frontal); DLB: Dementia with Lewy bodies; bvFTLD: Frontotemporal lobar degeneration, behavioural variant; PSP: Progressive supranuclear palsy; PPA: Primary progressive aphasia; Mixed: Mixed dementia (vascular + AD); MCI: Mild cognitive impairment; PPD: Primary psychiatric disorder; CH: Cognitively healthy. The colour bar represents z value.
