Neurocognitive aging research, explained
10 open-access neurocognitive aging studies, each with a flashcard deck and a quiz.
- How does brain wiring help preserve our thinking skills as we age?
Healthy patterns of direct neural communication between major brain networks become increasingly crucial for protecting cognitive performance as we grow older, compensating for the decline of local brain regions.
- Does brain tau protein affect object memory in older adults?
Elevated levels of tau protein in the brain fluid of healthy older adults are linked to overactivity in the hippocampus and worse memory for distinguishing highly similar objects.
- Does cognitive frailty in old age signal early Alzheimer's?
Older adults with cognitive frailty show brain structures and electrical responses similar to healthy peers, rather than those with Alzheimer's disease.
- Does the aging brain lose its specialisation for scenes and faces?
Older adults' scene-processing regions responded less selectively than younger adults', but their face-processing regions did not, and scene selectivity predicted memory equally at any age.
- Does crossing the digital divide protect late-life cognition?
In 10,098 BABRI participants, digital exclusion tracked with worse processing speed and higher MCI risk; overcoming it linked to slower decline and MCI reversion.
- Can brief brain or body training strengthen older adults' white matter?
Ten weeks of computer brain training or exercise did not change white matter integrity in older adults at risk of dementia, even though a cognitively active lifestyle was linked to better cognitive change.
- How the aging brain learns to see shapes in clutter
While older and younger adults improve equally at identifying visual shapes in noisy backgrounds, they rely on different brain pathways, with older adults relying more on attention networks in the parietal lobe rather than frontal decision-making areas.
- How Leisure Activities Buffer Age-Related Mental Slowing
Active leisure lifestyles help older adults stay mentally quick even when their brains process sensory information more slowly.
- How personality affects memory and brain patterns in older adults
Older adults who are highly open to experience show better memory because their brain activity patterns during learning look more like those of younger adults.
- Does worse depression plus chronic disease hit cognition harder?
Among 13,930 CHARLS adults ≥45, higher CES-D-10 depression tracked greater heart-disease risk, while depression plus hypertension or diabetes worsened cognition, episodic memory, and life satisfaction.
