Researchers at the University of Vermont College of Medicine, who analysed data from 35,000 US citizens aged 45 and over, identified 495 participants that were found to have issues with thinking and memory. Of these people, 6% were found to have AB blood.
While this percentage may seem small, this blood type is only found in 4% of the population.
The study, which was published in science journal Neurology, stated that these people were 82% more likely than others to develop cognitive issues in their later life.
However, if you are type AB you don’t need to worry yet. Head of Alzheimer’s Research UK, Dr Simon Ridley, commented in relation to the research that it did not specifically look at the risk of dementia in these patients. While the results show a susceptibility to memory loss, these findings must not be aligned with dementia.
“Our study looks at blood type and risk of cognitive impairment, but several studies have shown that factors such as high blood pressure, high cholesterol and diabetes increase the risk of cognitive impairment,” said Dr Mary Cushman, head of the research.
This is not the first time blood type has been found to impact a person’s health, for instance those with type O appear to be at lower risk for cardiovascular disease.
The best way to keep a healthy brain is a balanced diet, regular exercise and not smoking.
