Data‐driven thresholds for standardized classification of severe Alzheimer's disease neuropathology using digital neuropathology

Brain Pathology, EarlyView.
We generated digital pathologic algorithms (AI‐based modules that can be freely shared) to: optimize the sampling (ROI) for diagnosis of ADNC‐related tau pathology; compare/transition between Aperio and HALO platforms; and rationalize severe Braak NFT staging, so that all Braak‐VI cases had dementia, and all Braak‐V cases had MCI or dementia.

Wasteosomes accumulate in periventricular white matter hyperintensities and exhibit complex relationships with mixed pathology, sclerotic index, and perivascular space

Brain Pathology, EarlyView.
In a mixed diagnostic cohort of pathologically diagnosed Alzheimer's disease, cerebrovascular disease, mixed pathology, and control tissue, we connected the histopathological wasteosome profile in periventricular (PV) brain sections to 7T FLAIR‐MRI confirmed PV white matter hyperintensities (WMHs), vascular stenosis and perivascular space size ...

Comments to the “Letter to the Editor” for the manuscript titled “Increased expression of inflammasome signaling genes and proteins in selective brain regions in the intermediate stage of Alzheimer's disease”

Brain Pathology, EarlyView.
Beta amyloid diffuse plaques, neurofibrillary tangles and neuritic plaques, are increased in densities at the intermediate stage of Alzheimer's neuropathological change. These pathological changes releasing Pathogen‐Associated Molecular Patterns (PAMPs) and Damage‐Associated Molecular Patterns (DAMPs).
