In early Alzheimer's disease (AD), the hippocampal region is the area most severely affected by cellular and structural alterations, yet glucose hypometabolism predominates in the posterior association cortex and posterior cingulate gyrus. One prevalent hypothesis to account for this discrepancy is that posterior cingulate hypometabolism results from disconnection from the hippocampus through disruption of the cingulum bundle. However, only partial and indirect evidence currently supports this… Expand
Sequential relationships between grey matter and white matter atrophy and brain metabolic abnormalities in early Alzheimer's disease.
TLDR
The present study reinforces the relevance of remote mechanisms above local interactions to account for the pattern of metabolic brain alteration observed in amnestic mild cognitive impairment, and provides new avenues to assess the sequence of events in complex diseases characterized by multiple manifestations. Expand
Diaschisis-Like Association of Hippocampal Atrophy and Posterior Cingulate Cortex Hypometabolism in Cognitively Normal Elderly Depends on Impaired Integrity of Parahippocampal Cingulum Fibers.
TLDR
Interaction effects were such that the association of hippocampal volume and PCC metabolism was higher in subjects with increased mean diffusivity in PHC fibers, and compromised integrity of the PHC may increase the risk of PCC hypometabolism due to hippocampal atrophy in cognitively normal elderly. Expand
Connectivity Disruption, Atrophy, and Hypometabolism within Posterior Cingulate Networks in Alzheimer's Disease
TLDR
Functional connectivity (FC) disruption, atrophy, and hypometabolism within the ventral and dorsal PCC networks in patients with amnestic mild cognitive impairment (aMCI) or AD are highlighted and the pathology spreads from the vPCC to the dPCC networks. Expand
Regional Amyloid-β Load and White Matter Abnormalities Contribute to Hypometabolism in Alzheimer’s Dementia
TLDR
The interaction between, rather than the independent effects of, high levels of amyloid-β deposition and WM integrity disruption determined limbic hypometabolism in patients with AD, highlighting a more integrative model for AD. Expand
Does posterior cingulate hypometabolism result from disconnection or local pathology across preclinical and clinical stages of Alzheimer’s disease?
TLDR
The findings suggest that the effects of remote pathology on PCC hypometabolism decrease and theeffects of local pathology increase from preclinical to clinical stages of AD, consistent with a progressive disconnection of the PCC from downstream cortical and subcortical brain regions. Expand
Functional implications of hippocampal degeneration in early Alzheimer’s disease: a combined DTI and PET study
TLDR
Findings support the diaschisis hypothesis of AD and implicate a dysfunction of structures along the hippocampal output pathways as a significant contributor to the genesis of episodic memory impairment. Expand
Abnormal white matter independent of hippocampal atrophy in amnestic type mild cognitive impairment
TLDR
The findings supported the evidence of independent patterns of degeneration in WM tracts which may co-act in the WM pathological process of aMCI patients, and may assist with a better understanding of WM pathological change associated with the development of AD. Expand
Parietal cortex matters in Alzheimer's disease: An overview of structural, functional and metabolic findings
TLDR
A model showing the relationship between the various pathological events, as measured by different neuroimaging techniques, in the development of AD is proposed, which suggests myelin breakdown is a beginning of the chain of pathological events leading to AD pathology and an AD diagnosis. Expand
Measurement of Precuneal and Hippocampal Volumes Using Magnetic Resonance Volumetry in Alzheimer's Disease
TLDR
It is suggested that volumetric measurements of both the precuneus and hippocampus are useful radiological indices for the diagnosis of AD and the lack of correlation is attributable to local pathology rather than being a secondary consequence of MTL pathology. Expand
White matter disruption at the prodromal stage of Alzheimer's disease: Relationships with hippocampal atrophy and episodic memory performance
TLDR
Results indicate that fronto-hippocampal connectivity is reduced from the earliest pre-demential stages of AD, and may specifically contribute to early initial impairment in episodic memory. Expand

Atrophy is associated with posterior cingulate white matter disruption in dementia with Lewy bodies and Alzheimer’s disease
TLDR
Dementia disease progression as measured by global atrophy is associated with disruption of the white matter which connects posterior cingulate and lateral parietal regions, suggesting that in addition to the hypometabolism in these regions in AD and DLB, there is also disruption to thewhite matter connecting them. Expand
Relations between hypometabolism in the posterior association neocortex and hippocampal atrophy in Alzheimer's disease: a PET/MRI correlative study
TLDR
The findings with both ROIs and voxel based mapping replicate earlier reports of a relation between hippocampal atrophy and ipsilateral association cortex hypometabolism in Alzheimer's disease and document that this relation is both region specific and independent of the dementing process itself. Expand
Diffusion tensor imaging of cingulum fibers in mild cognitive impairment and Alzheimer disease
TLDR
Assessment of the cingulum fibers using diffusion tensor imaging may aid early diagnosis of Alzheimer disease. Expand
Retrosplenial cortex (BA 29/30) hypometabolism in mild cognitive impairment (prodromal Alzheimer's disease)
TLDR
It is proposed that the retrosplenial cortex may represent a key junction between prefrontal areas involved in implementing retrieval strategies for episodic memory and hippocampal‐based mnemonic processing, and is interpreted as a probable contributor to the memory impairment seen in mild cognitive impairment by disconnecting these two anatomical networks. Expand
Changes in hippocampal connectivity in the early stages of Alzheimer's disease: Evidence from resting state fMRI
TLDR
It is found that functional connectivity between the right hippocampus and a set of regions was disrupted in AD, and the disrupted hippocampal connectivity to the MPFC, vACC and PCC provides further support for decreased activity in "default mode network" previously shown in AD. Expand
In Vivo Mapping of Gray Matter Loss with Voxel-Based Morphometry in Mild Alzheimer's Disease
TLDR
This study has mapped gray matter density by means of voxel-based morphometry on T1-weighted MRI volume sets in 19 patients with mild AD and 16 healthy subjects of similar age and gender ratio and report highly significant clusters of gray matter loss with almost symmetrical distribution. Expand
Ultrastructural Hippocampal and White Matter Alterations in Mild Cognitive Impairment: A Diffusion Tensor Imaging Study
TLDR
Elevated MD values indicating brain tissue alterations in MCI patients were found in regions that are typically involved in early changes due to AD, particularly the left hippocampus. Expand
Voxel-based detection of white matter abnormalities in mild Alzheimer disease
TLDR
Voxel-wise comparison of whole-brain anisotropy revealed widely distributed disintegration of white matter in mild Alzheimer disease (AD), which may be an independent factor in the progress of AD. Expand
Relation between medial temporal atrophy and functional brain activity during memory processing in Alzheimer’s disease: a combined MRI and SPECT study
TLDR
Hippocampal atrophic changes in Alzheimer’s disease are associated with reduced functional activity in limbic and associative temporal regions during episodic memory processing, but with increased activity in frontal areas, possibly on a compensatory basis. Expand
Hippocampal disconnection contributes to memory dysfunction in individuals at risk for Alzheimer's disease.
TLDR
Results suggest that, in addition to hippocampal atrophy, disruption of parahippocampal white matter fibers contributes to memory decline in elderly individuals with MCI by partially disconnecting the hippocampus from incoming sensory information. Expand
