Association Between Gray Matter Microstructure and Glucose Metabolism in Older Adults With Cognitive Decline: A Multimodal Imaging Study
Cortical glucose hypometabolism is a well‐established early marker of neurodegeneration in dementia, mainly reflecting neuronal and synaptic dysfunction. Its relationship with underlying microstructural alterations remains unclear. Here, we combined multi‐shell diffusion microstructural and [18F]‐FDG PET data to invest...
