Artículo empírico que examina cómo dos marcadores de neurodegenración —tau total y cadena ligera de neurofilamento (NfL)— afectan la clasificación AT(N) de la enfermedad de Alzheimer en 177 participantes del Alzheimer's Disease Neuroimaging Initiative japonés. Se compararon la frecuencia de perfiles AT(N) entre clasificaciones que usaban tau total o NfL como marcador N, y se analizaron cambios biológicos y clínicos longitudinales. Los resultados muestran que los perfiles AT(N) difieren sustancialmente según el marcador N elegido: con tau total se asignan más frecuentemente estados N− o N+, mientras que con NfL los perfiles varían. El grupo del continuo Alzheimer mostró progresión clínica y biológica en ambas clasificaciones, pero la conversión a demencia fue más frecuente en el grupo de cambios patológicos no-Alzheimer solo con tau total. Se concluye que AT(N)tau y AT(N)NfL capturan aspectos diferentes de la neurodegeneración.

Puntos clave

La clasificación AT(N) con tau total y con neurofilamento ligero produce distribuciones sustancialmente distintas de perfiles de biomarcadores en la misma cohorte de participantes.
El continuo de enfermedad de Alzheimer mostró progresión clínica y biológica consistente en ambas clasificaciones AT(N), confirmando su validez como constructo.
El marcador N utilizado en la clasificación AT(N) determina el valor pronóstico, particularmente para predecir conversión a demencia en sujetos con cambios patológicos no-Alzheimer.

Para quién: Investigadores en neurobiología del Alzheimer, neurólogos y especialistas en diagnóstico por biomarcadores que busquen entender cómo la elección de marcadores de líquido cefalorraquídeo afecta la clasificación y pronóstico de la enfermedad de Alzheimer.

Resumen de los autores

Background The AT(N) classification was proposed for categorising individuals according to biomarkers. However, AT(N) profiles may vary depending on the markers chosen and the target population.Methods We stratified 177 individuals who participated in the Japanese Alzheimer’s Disease Neuroimaging Initiative by AT(N) classification according to cerebrospinal fluid (CSF) biomarkers. We compared the frequency of AT(N) profiles between the classification using total tau and neurofilament light chain (NfL) as N markers (AT(N)tau and AT(N)NfL). Baseline characteristics, and longitudinal biological and clinical changes were examined between AT(N) profiles.Results We found that 9% of cognitively unimpaired subjects, 49% of subjects with mild cognitive impairment, and 61% of patients with Alzheimer’s disease (AD) dementia had the biological AD profile (ie, A+T+) in the cohort. The frequency of AT(N) profiles substantially differed between the AT(N)tau and AT(N)NfL classifications. When we used t-tau as the N marker (AT(N)tau), those who had T− were more frequently assigned to (N)−, whereas those who had T+were more frequently assigned to (N)+ than when we used NfL as the N marker (AT(N)NfL). During a follow-up, the AD continuum group progressed clinically and biologically compared with the normal biomarker group in both the AT(N)tau and AT(N)NfL classifications. More frequent conversion to dementia was observed in the non-AD pathological change group in the AT(N)tau classification, but not in the AT(N)NfL classification.Conclusions AT(N)tau and AT(N)NfL in CSF may capture different aspects of neurodegeneration and provide a different prognostic value. The AT(N) classification aids in understanding the AD continuum biology in various populations.
