Conversely, ARIA-inducing monoclonal antibodies accelerated ventricular enlargement (Δ placebo - Δ drug: +2.1 mL [38.7% more than placebo]; 95% CI 1.5–2.8) where a striking correlation between ventricular volume and ARIA frequency was observed (r = 0.86, p = 6.22 × 10−7). Mild cognitively impaired participants treated with anti-Aβ drugs were projected to have a material regression toward brain volumes typical of Alzheimer dementia ∼8 months earlier than if they were untreated.Discussion These findings reveal the potential for anti-Aβ therapies to compromise long-term brain health by accelerating brain atrophy and provide new insight into the adverse impact of ARIA. Six recommendations emerge from these findings.Aβ=β-amyloid; ARIA=amyloid-related imaging abnormality; ARIA-E=ARIA edema; ARIA-H=ARIA hemorrhagic; FDA=Food and Drug Administration; IVIg=IV immunoglobulin; LTP=long-term potentiation; MCI=mild cognitive impairment; PIB=Pittsburgh compound B; PRISMA=Preferred Reporting Items for Systematic Reviews and Meta-Analyses; SUVR=standardized uptake value ratio
