In symptomatic genetic frontotemporal dementia, a CSF inflammation–brain axis linked to frontotemporal-insular atrophy predicts faster CDR-SB progression (beta=0.24, CI [0.02, 0.46]).
- Why it matters: Neuroinflammation is implicated in FTD, but its relationship to brain atrophy and measurable clinical or cognitive decline—especially early in genetic disease—remains unclear.
- What they did: In 234 participants (78 non-carrier controls, 115 presymptomatic carriers, 41 symptomatic carriers), rCCA derived a shared CSF protein–MRI covariance axis, then linear mixed-effects models estimated individual CDR and DSST slopes.
- The result: The inflammation–brain axis (r=0.89, p<0.001) tracked CDR-SB severity and predicted CDR-SB slope only in symptomatic carriers, while DSST links were cross-sectional and no significant associations appeared in presymptomatic carriers or non-carrier controls.
