Importance: The extent to which neuroanatomical variability associated with early substance involvement, which is associated with subsequent risk for substance use disorder development, reflects preexisting risk and/or consequences of substance exposure remains poorly understood.
Objective: To examine neuroanatomical features associated with early substance use initiation and to what extent associations may reflect preexisting vulnerability.
Design, Setting, And Participants: Cohort study using data from baseline through 3-year follow-up assessments of the ongoing longitudinal Adolescent Brain Cognitive Development Study.

Background: White matter hyperintensities (WMH) were reported to contribute to the thinning of regional cortex connected to WMH in cerebral small vessel disease. However, the relationship between WMH and regional changes in WMH-connected cortex in Alzheimer's disease (AD) remains unclear. The objective of this study is to investigate the association between WMH and regional cortical thickness, amyloid and tau deposition, and synaptic density changes in the WMH-connected cortex.

Background: Type 2 diabetes (T2D) is a recognized risk factor for dementia. This study aimed to pinpoint blood DNA methylation biomarkers for cognitive decline in older adults with T2D by comparing those who developed dementia with those who remained cognitively normal during follow-up METHOD: Illumina Infinium MethylationEPIC microarray was used for the initial 24 couples and Infinium HumanMethylationEPIC microarray version 2.0 for the subsequent 8 couples.

Background: Brain, cerebrospinal fluid (CSF), and plasma metabolomics have been informative in identifying disrupted metabolism pathways in Alzheimer's disease (AD). However, many AD-focused metabolomics studies profiled a relatively small number of individuals and metabolites, especially for CSF. In addition, past studies were limited to one or two tissues.

Background: Highly specific ATN plasma biomarker assays for neurodegenerative diseases have been developed, but their associations with cognition vary in different populations. Kidney disease, common in diabetes, may decrease the predictive precision of those biomarkers. The aim of this study was to characterize for the first time the relationships between plasma ATN biomarkers and cognitive function in adults with T1D.
