Summary

Dementia is one of the main chronic non-communicable diseases associated with disability, institutionalization, and mortality among elderly individuals. Alzheimer's disease (AD) and vascular dementia (VD) are considered to be the main types of dementia. A widely shared view is that future treatment strategies need to focus on treatment of the earliest stages of the disease. Mild cognitive impairment (MCI) constitutes an intermediate stage between normal aging and dementia. Vascular cognitive disorders (VCD) is an umbrella term representing a wide spectrum of cognitive disorder evoked by or associated with vascular causes. It encompasses patients suffering from a range of types of cognitive impairment, from mild impairment to VD. VCD predementia (VCD-P) is at the same stage of MCI. Amnestic MCI (aMCI) is a subtype of MCI, which is also considered to be the clinical transition stage between normal aging and AD, and has been applied to detect the emerging dementia. In VCD, infarcts or profuse white matter disease are considered the cause of cognitive decline. By contrast, AD is one of the most common progressive neurodegenerative disorders thought to be caused by amyloid aggregation and the formation of tau tangles. Both VCD-P and aMCI have a deficit in cognitive domains, and may have the same chief complaints of memory deficit. If it can be clear which will turn into what type of dementia in patients with cognitive impairment stage, it can not only make us more early intervention treatment to the patients, but also can save a lot of social resources and economic costs in clinic. By applying the resting state functional magnetic resonance (fMRI), structural magnetic resonance imaging (sMRI) and diffusion tensor magnetic resonance imaging (DTI) multimodal magnetic resonance (NMR) technology, the project comprehensive analysis comparison of neurodegenerative and blood vessels of brain function in patients with mild cognitive impairment and structural abnormalities connection mode. This project in order to reveal the cognitive impairment disease neural circuits in the development of the network connection and its change rule. People can further understand the pathogenesis of cognitive impairment, discover new will provide a scientific basis for prevention, diagnosis and treatment.
