Concise Statement: In Parkinson's disease, different epigenetic clock algorithms (Horvath, Hannum, PhenoAge, GrimAge) generate systematically divergent age estimates from the same DNA sample — and this inter-clock discordance score (IDS) is a novel, specific PD prodrome biomarker that reflects the cell-type-skewed aging pattern caused by dopaminergic neuron loss and compensatory glial proliferation.
Mechanistic Rationale:
Different epigenetic clocks are trained on different tissues and optimiz
Concise Statement: TDP-43 proteinopathy (as seen in LATE — Limbic-predominant Age-related TDP-43 Encephalopathy) generates a spatially and cellularly distinct epigenetic aging pattern in middle temporal gyrus spiny neurons that is dissociable from canonical AD-associated methylation drift, enabling a clock-based molecular differential diagnosis between LATE, AD, and mixed pathology.
Mechanistic Rationale:
TDP-43 is a major RNA-binding protein and transcriptional repressor whose nuclear clearan
