- 요약Alzheimer's Disease is characterized by intertwined disease pathology and cognitive impairment. Existing attempts to deconvolute disease pathology and to understand disease progression have been limited due to the inability to control for disease states in human subjects. Additionally, there is a lack of understanding of how biological factors can influence cognitive networks that result in cognitive impairments observed in Alzheimer's Disease. It is known that neuroinflammation is one of the hallmarks of Alzheimer's Disease pathology, and that perturbed functional networks are another hallmark related to cognitive deficits associated with Alzheimer's Disease. Thus, to increase our understanding of Alzheimer's Disease, this dissertation details the efforts and the experiments undertaken to elucidate how neuroinflammation and functional connectivity are related in Alzheimer's Disease. To achieve the objective of elucidating the relationship between the two modalities, we multiplexed individual brain regions to quantify regional neuroinflammatory signatures and utilized awake resting state fMRI to study the changes in functional networks over disease progression. We found that intermediate stages of disease development coincided with local functional changes involving subcortical regions before spreading globally at a fully symptomatic disease stage. We also found that diseased aging versus healthy aging yielded different regional neuroinflammatory profiles, with different cortical regions displaying unique features regarding which cytokines were involved in diseased aging. Additionally, we found that subcortical regions are also affected at the fully symptomatic stage of disease progression. These results provide the basis for further interrogation of functional network changes over disease development by indicating which brain regions are more affected by neuroinflammation and what the correlated functional changes are.
