abstract = {Directly compare the brain glucose patterns seen with
[F-18] fluorodeoxyglucose (FDG) positron emission tomography
(PET) between 2 genetically determined forms of Alzheimer's
disease: Down syndrome (DS) and autosomal dominant
Alzheimer's disease (ADAD).Cross-sectional analyses of FDG
were performed in individuals with DS (n = 76) from the
Alzheimer Biomarker Consortium-Down Syndrome (ABC-DS), ADAD
(n = 297), and neurotypical familial controls (n = 188) from
the Dominantly Inherited Alzheimer Network (DIAN).
Within-group linear regression models and generalized
additive models were performed for select regional FDG
uptake measures (isthmus cingulate and inferior parietal,
precuneus, middle temporal gyrus, and precentral gyrus).
Age, sex, apolipoprotein (APOE) ε4 carrier status, and
cortical amyloid burden were included within these
analyses.Even 20 years before expected onset of clinical
symptoms, FDG uptake was lower for DS compared to
neurotypical familial controls (p < 0.01). ADAD baseline FDG
was similar to neurotypical familial controls until 7 years
before expected symptom onset. Both symptomatic individuals
with DS and ADAD had lower FDG compared to neurotypical
familial controls (p < 0.01). A higher amyloid burden was
associated with lower FDG for both genetic forms, with
similar rates of decline in FDG uptake for DS and ADAD who
were amyloid positive.Brain glucose metabolism is
substantially lower for people with DS, even in individuals
who are cognitively stable. The patterns of FDG decline are
distinct in these 2 genetically determined forms of AD. The
diagnostic utility of FDG-PET is specific to the genetic
form of AD. ANN NEUROL 2025;98:1237-1248.},
