This NHS Choices “Behind the Headlines” critical appraisal of recent research featuring in the news is about whether anaemia in older adults is a potential risk factor for dementia and how to interpret the association discovered between anaemia, poor health and dementia.
The study reported here followed over 2,550 older adults for over a decade and found that those who had anaemia (of any cause, not just dietary) at the start of the study were more likely to go on to develop dementia. This study included all types of anaemia, not just anaemia caused by iron deficiency.
“The implications of these findings for dementia prevention are not clear”.
Further research is required.
