Long-term cohort separates Alzheimer pathology from cognitive resilience

In 3,119 older adults followed for a median 13.7 years, pathology and a derived cognitive-resilience measure independently tracked dementia risk; the observational analysis does not show causation.

Study design

The China Cognition and Aging Study contributed 3,119 older adults followed for a median 13.7 years. Researchers derived a pathology score from p-tau181 and amyloid-beta 42, plus a separate cognitive-resilience score based on cognitive trajectories adjusted for pathology, age, and sex.

What it found

Both dimensions were independently associated with dementia risk. Per standard-deviation increase, pathology was associated with higher risk (hazard ratio 2.50), while the resilience score was associated with lower risk (0.51).

Limits and interpretation

The resilience score is a statistical construct, not a direct test or intervention. The study is observational and from one Chinese cohort; it does not prove resilience prevents dementia or generalize automatically to other populations. The measure needs validation.

Mood changes and intrusive thoughts were linked to remembering intended actions

A study tested 120 younger and older adults; 117 entered prospective-memory analyses. Mood changes and intrusive thoughts were associated with remembering intended actions, but the results do not establish a causal mechanism or a treatment for memory problems.

Brain connectivity patterns differed between Alzheimer’s pathology and aging

MRI analyses in BioFINDER-2 and ADNI linked Alzheimer’s pathology and age to different whole-cortex connectivity gradients. The cohort findings describe associations and do not establish a diagnostic test or causal mechanism.

Small blackcurrant blend trial finds selective attention changes in older adults

A crossover trial analyzed 26 older adults after four-week periods of a blackcurrant, L-theanine and pine-bark blend or placebo. Attention-task false alarms declined, but memory and fatigue findings were not significant after multiple-testing correction; the blend cannot isolate an ingredient.
