Washington: Anaemia, or low levels of red blood cells, may increase the risk of dementia, a new study has found. US researchers tested 2,552 older adults between the ages of 70-79 for anaemia. The participants also underwent memory and thinking tests over 11 years. Of those, 393 had anaemia at the start of the study. At the end of the study, 445, or about 18 per cent of participants, developed dementia. The research found that people who had anaemia at the start of the study had a nearly 41 per cent higher risk of developing dementia than those who were not anaemic. The link remained after considering other factors, such as age, race, sex and education.
