内容摘要:
Dementia currently affects over 50 million older people globally, costs 1 trillion US dollars a year, and is estimated to increase to over 152 million people by 2050 with increasing life expectancy. Pivotal to responding to this "time bomb" are biomarkers that predict susceptibility to dementia, and in-depth understanding of its neurocognitive mechanisms. Neural degeneration and dysfunction leading to dementia may begin decades before symptoms and cognitive decline present. Hence, the recognition of early imaging markers of dementia may allow more effective intervention or even prevent dementia from happening. In addition, brain inspired Artificial Intelligence (AI) is beginning to achieve if not surpass human-level performance. So, AI can also provide important theoretical and mechanistic framework for brain dysfunctions in aging and neurodegeneration.
Here, I will present current and recent neuroimaging research conducted in my lab in University of Cambridge and collaborating centres nationally (Oxford, Imperial and Edinburgh) and internationally (Dublin and China) in seeking for potential early neuroimaging biomarkers for different types of dementia, such as Alzheimer's disease and Lewy body dementia. I combine multimodal imaging (MEG, EEG, MRI and PET) with genetics and AI based computational modelling to reveal neural mechanisms underlying dementia, and how risk factors (e.g. family history of dementia, APOE and MAPT genotype) affect brain structure, functions and behaviours across lifespan including in young and mid aged individuals. Multimodal imaging and genetics have the potential to identify early changes in brain structure and functions at both regional and molecular levels. However, characterising their relationships and neural mechanisms requires formal modelling such as computational psychiatry approaches.
