Grey matter microstructural alterations distinguish cognitive impairment in Lewy body diseases

The paper identifies grey matter microstructural changes in Lewy body diseases using diffusion MRI metrics, finding increased tODI and FWF linked to cognitive impairment and p-tau217 levels.

Evidence for divergent cortical organisation in Parkinsons disease and Lewy Body Dementia

The paper uses neuroimaging to compare structural and functional connectivity gradients in Parkinson's disease with normal cognition and Lewy body dementia, finding divergent patterns associated with cognitive impairment.

A molecular map of the living human brain from quantitative MRI

This paper introduces a non-invasive imaging framework combining qMRI and SRT to infer molecular features in neurodegeneration.

Neuroimaging and plasma biomarker differences and commonalities in Lewy body dementia subtypes

The paper compares neuroimaging and plasma biomarkers in Lewy body dementia subtypes, finding differences in white matter integrity and plasma markers between dementia with Lewy bodies and Parkinson's disease dementia.

Impaired glymphatic clearance independently contributes to poor outcomes in Parkinsons disease

The paper shows impaired glymphatic clearance is linked to poor outcomes in Parkinson's disease, with distinct effects on brain structure and iron distribution.

Neuroimaging and plasma marker evidence for white matter macrostructure loss in Parkinsons disease

The paper shows that white matter macrostructure loss and elevated plasma neurofilament light chain levels are associated with poor outcomes in Parkinson's disease.

Changes in both top-down and bottom-up effective connectivity drive visual hallucinations in Parkinson's disease

This study uses spectral dynamic causal modelling to show that visual hallucinations in Parkinson's disease are linked to reduced bottom-up and increased top-down effective connectivity in the visual network.

Quantitative MRI maps of human neocortex explored using cell type-specific gene expression analysis

The paper links quantitative MRI parameters to cell type-specific gene expression in human neocortex, showing associations with GABA- and glutamatergic neurons and other cell types.

Changes in dynamic transitions between integrated and segregated states underlie visual hallucinations in Parkinson's disease

The paper examines dynamic brain state transitions in Parkinson's disease patients with visual hallucinations, finding altered temporal dynamics and links to neurotransmitter systems.

Visual dysfunction predicts cognitive impairment and white matter degeneration in Parkinson's disease

The paper shows that visual dysfunction in Parkinson's disease is linked to cognitive decline and white matter damage over time.
