Processed FDG-PET data from: A computational model of neurodegeneration in Alzheimer’s disease

Disruption of mental functions in Alzheimer’s disease (AD) and related
disorders is accompanied by selective degeneration of brain regions. These
regions comprise large-scale ensembles of cells organized into systems for
mental functioning, however the relationship between clinical symptoms of
dementia, patterns of neurodegeneration, and functional systems is not
clear.  We developed a model of the association between dementia
symptoms and degenerative brain anatomy using F18-fluorodeoxyglucose (FDG)
PET and dimensionality reduction techniques patients with AD. This data
and code package contains preprocessed FDG-PET images from 423 subjects
across the Alzheimer’s disease spectrum and the MATLAB code to produce
eigenbrains from this data.
