Summary
This project investigates the role of cerebrovascular function in various forms of dementia, including Alzheimer's and frontotemporal dementia. Using large neuroimaging datasets and advanced cerebrovascular mapping techniques (see references), we aim to evaluate how vascular dysfunction influences neurodegenerative changes across different dementia types.
Project aims
The study will contribute to understanding underlying mechanisms and potential therapeutic targets.
The project offers an opportunity to develop expertise in multimodal neuroimaging, data science, and advanced analytics (both data drive AI modelling and hypothesis-driven path analysis) and cerebrovascular biology, while making significant contributions to dementia research at the intersection of neuroscience and data science.
