What mechanisms underlie TDP-43's contribution to cognitive impairment severity in AD patients?

PARTIALLY ADDRESSED

AD patients with TDP-43 pathology show worse cognitive impairment, but how TDP-43 mechanistically contributes to this severity is unknown. Understanding this could identify TDP-43 as a therapeutic target for cognitive preservation in AD. Gap type: unexplained_observation Source paper: TDP-43 Pathology in Alzheimer's Disease. (2021, Mol Neurodegener, PMID:34930382)
