Claim 5 of 7Not checkedFor vascular dementia, people in the lowest hemoglobin category had a 19% higher risk and those in the highest category had an 18% higher risk, although the association did not follow a consistent pattern across all five hemoglobin groups.View evidenceHide evidence

Claim 6 of 7Not checkedThe study was observational, so it cannot determine whether abnormal hemoglobin levels directly cause dementia, and the researchers said abnormal hemoglobin may instead be a marker of broader physical vulnerability relevant to brain health.View evidenceHide evidence
