"People with a rare blood type may be at greater risk of memory loss later in life, according to a new study.
The study, published in the US journal Neurology, found that people with the blood type AB were 82 percent more likely to develop problems with day-to-day memory, language and attention as they age than people with other blood types.
People with the AB blood type account for about three percent of the Australian population, according to the Australian Red Cross Blood Service.
Researchers examined data from a US study of over 30,000 people aged 45 and up. They found that 495 of the participants who initially reported no issues had gone on to develop memory or cognitive impairment over a three-and-a-half-year period, based on cognitive tests.
They were compared to a similar group of 587 adults who did not have any signs of memory problems.
People with AB blood type made up six percent of the group who developed cognitive impairment, which is higher than the four percent found in the general US population.
The study's author, Mary Cushman, said the findings highlight the connections between vascular issues and brain health.
"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 and dementia," Dr Cushman said.
However, the study did not look at the risk of dementia and Dr Cushman said more studies were needed to confirm her results.
Experts say the best way to keep the brain healthy is a balanced diet, regular exercise and not smoking."
