The seed region of interest covariance analysis revealed distinct (18) F - labelled fluorodeoxyglucose correlation patterns that greatly overlapped with the right executive - control network for the early - onset Alzheimer's disease region of interest, the left language network for the logopenic variant primary progressive aphasia region of interest, and the higher visual network for the posterior cortical atrophy region of interest.

Goodness - of - fit analysis of each connectivity map with network templates showed the highest correspondence between the early - onset AD seed connectivity map and anterior salience and right executive - control networks, the logopenic aphasia seed connectivity map and the language network, and the posterior cortical atrophy seed connectivity map and the higher visual network.

Finally, (18) F - labelled fluorodeoxyglucose was similarly reduced in all Alzheimer's disease variants in the dorsal and left ventral default mode network, whereas significant differences were found in the right ventral default mode, right executive - control (both lower in early - onset Alzheimer's disease and posterior cortical atrophy than logopenic variant primary progressive aphasia) and higher - order visual network (lower in posterior cortical atrophy than in early - onset Alzheimer's disease and logopenic variant primary progressive aphasia), with a trend towards lower (18) F - labelled fluorodeoxyglucose also found in the left language network in logopenic variant primary progressive aphasia.

We performed task - free («resting - state») functional imaging in 60 nonfamilial AD patients, including 20 early - onset AD (age at onset < 65 years, amnestic / dysexecutive deficits), 24 logopenic aphasia (language deficits), and 16 posterior cortical atrophy patients (visual deficits), as well as 60 healthy controls.

They include conditions which have been referred to as perceptual handicaps, brain injury, minimal brain dysfunction, dyslexia, developmental aphasia, etc... they do not include learning problems which are due primarily to visual, hearing, or motor handicaps, to mental retardation, emotional disturbance or to environmental deprivation.»
