Abstract:BackgroundThe pathognomonic lesion of chronic traumatic encephalopathy (CTE) is the perivascular deposition of neuronal phosphorylated tau (p‐tau). Patchy p‐tau deposits initially accumulate in frontotemporal cortices. Medial temporal lobes (MTL) become involved in late stage. Validated in vivo biomarkers for CTE p‐tau do not exist. 18F‐MK‐6240 is a second‐generation tau PET ligand with improved imaging properties compared with first‐generation ligands, but its utility in CTE is unknown. We report initial resu… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
