Plasma p-Tau217 and GFAP predict widespread cognitive decline in Alzheimer's disease

Topic: Plasma and spinal-fluid biomarkers
Elevated CSF p-Tau181 and NfL levels were associated with greater decline in memory and executive function. Among plasma biomarkers, p-Tau217 and GFAP showed the strongest associations with widespread cognitive decline, particularly in language, visuospatial, and executive domains. These associations were independent of age at onset, clinical phenotype, and APOE ε4 status. DISCUSSION/ Our findings highlight the potential prognostic value of fluid biomarkers in AD, especially CSF p-Tau181 and NfL, and plasma p-Tau217 and GFAP. These results suggest promise for improving disease monitoring, although prognostic utility at the individual level remains uncertain.

How this study scored 52/100
Published in a peer-reviewed journal. Scored zero for study design, effect reported and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record, multi-centre collaboration and free to read, so those were left out: it earned 29 of the 56 points we could judge it on, which is 52 out of 100.
