Cortical thickness across the lifespan in a Colombian cohort with autosomal-dominant Alzheimer's disease: A cross-sectional study / Sergio Álvarez Vallejo ; Martín Ochoa Escudero
Título : Cortical thickness across the lifespan in a Colombian cohort with autosomal-dominant Alzheimer's disease: A cross-sectional study Tipo de documento : documento electrónico Autores : Sergio Álvarez Vallejo, ; Martín Ochoa Escudero, Fecha de publicación : 2021 Títulos uniformes : Alzheimer’s & Dementia. Diagnosis, Assessment & Disease Monitoring Idioma : Inglés (eng) Palabras clave : age-related cortical thickness familial Alzheimer's disease lifespan presenilin1 trajectory Resumen : Introduction: Cortical thinning is a marker of neurodegeneration in Alzheimer's disease (AD). We investigated the age-related trajectory of cortical thickness across the lifespan (9-59 years) in a Colombian kindred with autosomal dominant AD (ADAD). Methods: Two hundred eleven participants (105 presenilin-1 [PSEN1] E280A mutation carriers, 16 with cognitive impairment; 106 non-carriers) underwent magnetic resonance imaging. A piecewise linear regression identified change-points in the age-related trajectory of cortical thickness in carriers and non-carriers. Results: Unimpaired carriers exhibited elevated cortical thickness compared to non-carriers, and thickness more negatively correlated with age and cognition in carriers relative to non-carriers. We found increased cortical thickness in child carriers, after which thickness steadied compared to non-carriers prior to a rapid reduction in the decade leading up to the expected age at cognitive impairment in carriers. Discussion: Findings suggest that cortical thickness may fluctuate across the ADAD lifespan, from early-life increased thickness to atrophy proximal to clinical onset.
