Functional brain abnormalities of FTD and PPD compared to controls. Abbreviations: bvFTD = behavioural variant of frontotemporal dementia; PPD = primary psychiatric disorders. Patterns of brain metabolism of FTD and PPD patients versus cognitively normal controls, adjusted for age, sex, psychotropic drugs, scanner type. Surface rendering of significant voxels from contrasts between FTD, PPD patients and controls are displayed at p < 0.005 for visual purposes, extent threshold k = 0. Analysis of bvFTD versus controls was not adjusted for psychotropic drug use due to a small sample size. Significant clusters are displayed in Table 2. Images were created with BrainNet [35]
