Abstract:

With the advent of an aging society,Alzheimer′s disease (AD) has gradually become a major ailment affecting the elderly. AD is a neurodegenerative disorder associated with cognitive impairments. In AD patients, brain network connections are disrupted, and their topological properties are also affected, leading to the disintegration of anatomical and functional connections. Anatomical connections can be tracked and evaluated using structural magnetic imaging(MRI) and diffusion tensor imaging(DTI), while functional connections are detected through functional MRI to assess their connectivity status. This review incorporates the findings of previous scholars and summarizes the current research of AD. It mainly discusses the imaging characteristics of large-scale brain network changes in AD patients, so as to provide researchers with scientific and objective imaging markers for AD prediction and early diagnosis, as well as future research.

Key words: Alzheimer′s disease, brain network, functional magnetic resonance imaging, functional connectivity, small world attributes
