Heart, kidney and metabolic syndrome linked to brain disorders
In UK Biobank, stage 4 had a dementia hazard ratio of 1.91, a relative risk measure; the abstract did not specify the comparison stage.

Limit: The analysis did not measure whether treating CKM syndrome prevents brain disorders
Edited by Boris Djordjevic · AgingResearch.News
An observational study analyzed data from 321,107 adults aged 45 or older across four population datasets. Researchers examined cardiovascular-kidney-metabolic syndrome, which concerns the heart, kidneys and metabolism—the body’s use of energy. They assessed stages ranging from 0 to 4 and adjusted their models for demographic characteristics, lifestyle factors and cancer history.
More advanced stages were associated with higher risks of dementia, Parkinson’s disease, depression, anxiety and sleep disorders. The syndrome was also linked to accelerated aging on a biological aging measure and smaller volumes in certain brain regions. The authors suggested that inflammatory markers, biological aging and certain proteins may partly account for the associations.
Why it matters
The authors suggested that early intervention in this syndrome may be important for thinking and emotional well-being in middle-aged and older adults.
Caveats
This observational analysis cannot show that the syndrome caused the disorders or that intervention would prevent them. The analysis covered adults aged 45 or older, not younger people.
