Even safe high blood pressure increases dementia risk
Fifty-year-olds with blood pressure higher than normal, but still within the recommended safe limits, are at increased risk of dementia in later life, according to a large observational study of 8000 older adults.
Specifically, a systolic reading of 130mmHg is enough to endanger them, the results show.
This is much lower than the conventional 140mmHg threshold used to define hypertension.
And this excess risk is independent of cardiovascular disease, the researchers note in the European Heart Journal.
Lead author Professor Archana Singh-Manoux, who is linked to both the National Institute of Health and Medical Research in Paris and University College London, says the work confirms the detrimental effects of midlife hypertension on dementia risk.
“Our analysis suggests that the importance of midlife hypertension on brain health is due to the duration of
