The Mild Behavioral Impairment Checklist (MBI?C) was developed to capture new?onset transdiagnostic NPS in individuals at risk of dementia. We sought to determine whether mild behavioral impairment symptoms are elevated in non?demented Presenilin?1 (PSEN1) E280A carriers, who are genetically determined to develop dementia by their 50s. We hypothesized that those with higher MBI?C total scores would have worse memory performance and greater brain pathology. Method A total of 25 mutation carriers (mean age = 36.3±7.23; 56% females; 18 cognitively?unimpaired, 7 impaired) and 30 non?carriers (70% females) from the Colombia?Boston (COLBOS) Biomarker study were included. All participants completed cognitive testing, the MBI?C (self?reported), and florbetapir (amyloid), flortaucipir (tau) PET, and structural magnetic resonance imaging. We used Mann?Whitney Test to examine group differences, and Spearman’s correlation and linear regression to examine associations among MBI?C total score, Geriatric Depression Scale?15 (GDS), Mini?Mental State Examination (MMSE), CERAD word list learning delayed recall, cortical amyloid burden, regional tau, and hippocampal volume. In sensitivity analyses, we restricted carriers to the 18 unimpaired. Resul MBI?C total scores were similar between carriers and non?carriers (p = 0.09). Compared to non?carriers, carriers had greater amyloid burden (r = 0.55; p = 0.004) and lower hippocampal volume (r = ?0.43; p = 0.034). Among all carriers, higher MBI?C total scores were associated with lower hippocampal volume (r = ?0.44; p = 0.034), greater amyloid burden (r = 0.5; p = 0.011), and worst memory performance (r = ?0.36; p = 0.021). There were no associations with tau pathology (p?values>0.05). Sensitivity analyses were consistent with previous results except for hippocampal volume (r = ?0.4; p = 0.08). Conclusión Findings suggest that NPS captured by MBI?C are associated with pathology and memory in a Colombian kindred with autosomal dominant AD, years before the median age of dementia onset in this cohort. This underscores the importance of behavioral symptoms in preclinical and prodromal ADAD. Follow?up analyses with larger samples and longitudinal assessments are needed to characterize neuropsychiatric symptom evolution as an early marker and target for intervention.

Título : Associations between subregional thalamic volume and brain pathology in autosomal dominant Alzheimer's disease Tipo de documento : documento electrónico Autores : Sergio Álvarez Vallejo, ; Martín Ochoa Escudero, Fecha de publicación : 2021 Títulos uniformes : Brain Communications Idioma : Inglés (eng) Palabras clave : Presenilin-1 thalamus MRI PET imaging preclinical Resumen : Histopathological reports suggest that subregions of the thalamus, which regulates multiple physiological and cognitive processes, are not uniformly affected by Alzheimer’s disease. Despite this, structural neuroimaging studies often consider the thalamus as a single region. Identification of in vivo Alzheimer’s-dependent volumetric changes in thalamic subregions may aid the characterization of early nuclei-specific neurodegeneration in Alzheimer’s disease. Here, we leveraged access to the largest single-mutation cohort of autosomal-dominant Alzheimer’s disease to test whether cross-sectional abnormalities in subregional thalamic volumes are evident in non-demented mutation carriers (n = 31), compared to non-carriers (n = 36), and whether subregional thalamic volume is associated with age, markers of brain pathology, and cognitive performance. Using automatic parcellation we examined the thalamus in six subregions (anterior, lateral, ventral, intralaminar, medial, posterior) and their relation to age and brain pathology (amyloid and tau), as measured by PET imaging. No between-group differences were observed in the volume of the thalamic subregions. In carriers, lower volume in the medial subregion was related to increased cortical amyloid and entorhinal tau burden. These findings suggest that thalamic Alzheimer’s-related volumetric reductions are not uniform even in preclinical and prodromal stages of autosomal-dominant Alzheimer’s disease and therefore, this structure should not be considered as a single, unitary structure in Alzheimer’s disease research.

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.
