TL;DR: Using digital histology in a large autopsy cohort of Lewy body disorder patients with dementia to test the hypotheses that co‐occurring Alzheimer disease pathology impacts the anatomic distribution of α‐synuclein (SYN) pathology and that co-occurring neocortical tau pathology in LBDs associates with worse cognitive performance and occurs in a pattern differing from AD.

TL;DR: Excessive mitochondrial fragmentation, dysregulated mitophagy, and impaired response to energetic stress in the pathogenesis of mitochondrial optic neuropathies, potentially linked with mitochondrial mislocalization and mtDNA depletion are demonstrated.

TL;DR: To measure postmortem burden of frontotemporal lobar degeneration with TDP‐43 (FTLD‐TDP) or tau (FT LD‐Tau) proteinopathy across hemispheres in primary progressive aphasia (PPA) using digital histopathology and to identify clinicopathological correlates of these distinct proteinopathies.

TL;DR: The longitudinal findings suggest that bvFTD individuals with higher lifetime cognitive experience demonstrate more rapid decline on measures of executive function, and this finding converges with cross-sectional evidence suggesting that lifetime cognitive experiences contribute to heterogeneity in clinical progression in bv FTD.
