People with Alzheimer’s have a higher risk of anaemia than people without the disease according to new research presented at the International Conference of Alzheimer’s Disease today (Tuesday 13 July 2010). Conversely, the Australian study also found that people with anaemia had an increased risk of Alzheimer’s.
Researchers analysed blood samples of 1,112 people. They measured the proteins haemoglobin and transferrin that carry iron in the blood, as well as testing their red blood cells. They found that people with Alzheimer’s disease had significantly less iron in their blood and were 2.61 times more likely to have anaemia. People with anaemia had a 2.56 times higher risk of developing Alzheimer’s. There were no reported differences in the amount of iron in the diets of people with Alzheimer’s and those without.
Alzheimer’s Society comment:
‘It is not really clear why people with dementia should be more susceptible to anaemia but this research provides an interesting avenue of investigation.
‘Anaemia can have a huge impact on quality of life, causing fatigue, weakness and shortness of breath. Although treatable, like other health problems for people with dementia, it can often be overlooked. If this is to change, it is vital GPs are given the necessary training to support people with dementia. It is also important that people with dementia attend regular GP checks to ensure they remain in the best health possible.’
