New evidence
Stroke survivors with lower serum albumin showed a clear cognitive decline difference — a meta-analysis of 9 studies found the gap averaged 3.85 units, but the link is only in a clinical population and hasn't been tested in healthy adults.
This is the first systematic review to tie low albumin to post-stroke cognitive impairment, but with no data on healthy people and no dose specified, it's an early clue — not a conclusion you can act on yet.
Researchers pooled data from 9 studies and found that stroke survivors who later developed cognitive impairment had significantly lower levels of albumin in their blood compared to those who didn't. Albumin, a protein made by the liver that reflects nutritional status and inflammation, might help flag who's at risk — but the findings only apply to people who've already had a stroke, and the studies didn't test whether raising albumin levels changes the outcome.
Where this fits in the evidence
This is among the first studies we've indexed on Albumin for Reduced Cognitive Impairment — treat it as an early signal until more research accumulates.
