Figure 3 Imaging abnormalities in the presymptomatic stage of genetic FTD
Figure 3 | Imaging abnormalities in the presymptomatic stage of genetic FTD. a | Grey matter changes from the Genetic Frontotemporal Dementia Initiative (GENFI) study: standardized difference between all (presymptomatic and symptomatic) mutation carriers and noncarriers in cortical grey matter volumetric imaging measures, versus estimated number of years from expected symptom onset for a given difference in volume between carriers and noncarriers. Dotted lines on the x-axis show the time at which the upper 95% confidence intervals for each curve crosses zero on the y-axis (that is, the point at which a statistically significant difference exists between mutation carriers and noncarriers). b | Changes in fractional anisotropy (red) as measured by diffusion tensor imaging. Presymptomatic carriers of GRN and MAPT mutations have decreased fractional anisotropy in the uncinate fasciculus versus control individuals. c | Changes in brain perfusion (red) as measured by arterial spin labelling. Presymptomatic GRN mutation carriers have a lower cross-sectional cerebral blood flow at follow-up than in control individuals. Part a modified with permission from Elsevier © Rohrer, J. D. et al.
