Stable Individual Differences Dominate Adult Brain Volume Variation Until Later Life

This study examines how brain volume differences in adults are stable from young adulthood or change with age, using MRI data from 8,311 individuals.

Vulnerability to memory decline in aging. A mega-analysis of structural brain change.

This study investigates the relationship between brain atrophy and memory decline in aging using longitudinal data, finding a nonlinear association that intensifies with age and is influenced by APOE ε4 carriership.

Reliability of structural brain change in cognitively healthy adult samples.

This study assesses the reliability of structural brain change in cognitively healthy adults over time, finding that longer follow-up periods significantly improve reliability compared to increasing observation frequency.

Is short sleep bad for the brain? Brain structure and cognitive function in short sleepers

The paper investigates the effects of short sleep on brain structure and cognitive function, finding that short sleepers without daytime tiredness have larger brain volumes but slightly lower cognitive scores.

Sleep duration and brain structure - phenotypic associations and genotypic covariance

This study examines the relationship between sleep duration and brain structure using MRI data, finding that 6.8 hours of sleep is associated with the most favorable brain outcomes, with genetic analyses suggesting homeostatic regulation of sleep duration.

Reliability of quantitative multiparameter maps is high for MT and PD but attenuated for R1 and R2* in healthy young adults

The paper assesses the reliability of four MRI parameters in healthy young adults, finding high reliability for MT and PD but lower for R1 and R2* across brain regions.

Individual variations in Brain age relate to early life factors more than to longitudinal brain change

This study finds that adult brain age is more influenced by early life factors like birth weight and polygenic scores than by longitudinal brain decline.

Education and income show heterogeneous relationships to lifespan brain and cognitive differences across European and US cohorts

The paper examines how education and income relate to brain and cognitive differences across European and US cohorts, finding heterogeneous effects and stronger associations in US samples.

Asymmetric thinning of the cerebral cortex across the adult lifespan is accelerated in Alzheimer's Disease

The paper identifies asymmetric thinning of the cerebral cortex across aging and Alzheimer's Disease, showing that the initially thicker hemisphere thins faster, with this pattern replicated across multiple cohorts.

Hippocampal and parahippocampal grey matter structural integrity assessed by multimodal imaging is associated with episodic memory in old age

The paper introduces a multimodal imaging approach to assess grey matter structural integrity in older adults and finds it correlates with episodic memory, particularly in men.

The genetic organization of subcortical volumetric change is stable throughout the lifespan

This paper identifies stable developmental clusters of subcortical volumetric change across the lifespan and shows genetic organization within these clusters.

Self-reported sleep problems are related to cortical thinning in aging but not memory decline and amyloid-β accumulation - results from the Lifebrain consortium

The paper examines the relationship between self-reported sleep parameters and cortical thinning in aging, finding associations with specific brain regions but not with memory decline or amyloid-β accumulation.

Hippocampal subfields and limbic white matter jointly predict learning rate in older adults

This study shows that limbic white matter microstructure and hippocampal subfield volumes together predict verbal learning rates in older adults, with an interaction effect observed.

Developmental cognitive neuroscience using Latent Change Score models: A tutorial and applications

The paper introduces latent change score models for analyzing developmental changes in brain and behavior using longitudinal data, showing correlated brain-behavior changes and sex differences in cortical thinning.
