Assessing the reliability of hippocampal single-voxel proton magnetic resonance spectroscopy through intra-class effect decomposition

The hippocampus is crucial for learning, memory, and stress regulation, but is vulnerable to influences that compromise its structural and metabolic integrity. Proton magnetic resonance spectroscopy (MRS) enables in vivo quantification of hippocampal neurochemistry, yet the absolute and relative reliability of these...

Impact of brain and blood iron on glial density in aging, and relations to cognition: evidence from a 5-year longitudinal multimodal MRI-PET study.

It is suggested that higher local subcortical iron accumulation contributes to low-grade neuroinflammation in middle-aged and older adults, but only brain iron accounts for cognitive and motor decline, indicating that low-grade neuroinflammation may partly constitute an adaptive response to the deleterious effects of i...
