Abstract

Background Major prevention trials for Alzheimer’s disease (AD) are now focusing on multidomain lifestyle interventions. However, the exact combination of behavioral factors related to AD pathology remains unclear. In 2 cohorts of cognitively unimpaired individuals at risk of AD, we examined which combinations of personality traits, neuropsychiatric symptoms, and cognitive lifestyle (years of education or lifetime cognitive activity) related to the pathological hallmarks of AD, amyloid-β, and tau deposits. Methods A total of 115 older adults with a parental or multiple-sibling family history of sporadic AD (PREVENT-AD [PRe-symptomatic EValuation of Experimental or Novel Treatments for AD] cohort) underwent amyloid and tau positron emission tomography and answered several questionnaires related to behavioral attributes. Separately, we studied 117 mutation carriers from the DIAN (Dominant Inherited Alzheimer Network) study group cohort with amyloid positron emission tomography and behavioral data. Using partial least squares analysis, we identified latent variables relating amyloid or tau pathology with combinations of personality traits, neuropsychiatric symptoms, and cognitive lifestyle. Results In PREVENT-AD, lower neuroticism, neuropsychiatric burden, and higher education were associated with less amyloid deposition (p = .014). Lower neuroticism and neuropsychiatric features, along with higher measures of openness and extraversion, were related to less tau deposition (p = .006). In DIAN, lower neuropsychiatric burden and higher education were also associated with less amyloid (p = .005). The combination of these factors accounted for up to 14% of AD pathology. Conclusions In the preclinical phase of both sporadic and autosomal dominant AD, multiple behavioral features were associated with AD pathology. These results may suggest potential pathways by which multidomain interventions might help delay AD onset or progression.

Abstract

Background: Both subjective cognitive decline (SCD) and a family history of Alzheimer's disease (AD) portend risk of brain abnormalities and progression to dementia. Posterior default mode network (pDMN) connectivity is altered early in the course of AD. It is unclear whether SCD predicts similar outcomes in cognitively normal individuals with a family history of AD. Methods: We studied 124 asymptomatic individuals with a family history of AD (age 64 ± 5 years). Participants were categorized as having SCD if they reported that their memory was becoming worse (SCD+). We used extensive neuropsychological assessment to investigate five different cognitive domain performances at baseline (n = 124) and 1 year later (n = 59). We assessed interconnectivity among three a priori defined ROIs: pDMN, anterior ventral DMN, medial temporal memory system (MTMS), and the connectivity of each with the rest of brain. Results: Sixty-eight (55%) participants reported SCD. Baseline cognitive performance was comparable between groups (all false discovery rate-adjusted p values >.05). At follow-up, immediate and delayed memory improved across groups, but the improvement in immediate memory was reduced in SCD+ compared with SCD− (all false discovery rate–adjusted p values −, SCD+ subjects showed increased pDMN–MTMS connectivity (false discovery rate–adjusted p

3. McGill University Researcher Publishes New Study Findings on Alzheimer Disease (Insulin-like growth factor binding protein-2 in at-risk adults and autopsy-confirmed Alzheimer brains).

Abstract

A new study conducted by researchers at McGill University explores the role of insulin-like growth factor binding protein-2 (IGFBP2) in Alzheimer's disease (AD). The study found that CSF IGFBP2 levels progressively increased over 5 years in asymptomatic individuals at risk for AD. Elevated levels of CSF and plasma IGFBP2 were associated with a greater risk of AD conversion. The findings suggest that CSF and plasma IGFBP2 may serve as valuable markers for identifying individuals at risk for AD and those with a higher risk of disease progression.

Abstract

A recent study conducted by researchers at McGill University in Quebec, Canada, examined the association between elevated amyloid and tau positron emission tomography (PET) signals and the development of Alzheimer's disease symptoms in older adults without cognitive impairment. The study used data from four independent population-based cohorts collected between 2003 and 2021. The results showed that older individuals without cognitive impairment who had elevated amyloid and tau PET signals were at near-term risk of developing symptomatic Alzheimer's disease within 2 to 3 years. The findings confirm the clinical prognostic value of the National Institute on Aging-Alzheimer's Association (NIA-AA) research criteria. [Extracted from the article]
