According to a three-year research, individuals with blood type AB were twice as likely to experience memory problems as those with type O blood.
However, experts stated that the findings should not be considered as alarming since there are other factors that impact memory risks more than blood types.
Dr. Mary Cushman from the University of Vermont College of Medicine noted that blood type is related to other vascular conditions like stroke, pointing out that the findings of the study highlight the connections between vascular issues and brain health.
She also emphasized that more research is needed to confirm these results.
It is worth noting that researchers examined 495 participants who had developed thinking, memory, or other cognitive problems and compared them to 587 people who had no cognitive problems.
Participants who had AB blood type made up six percent of the entire group and they were the ones who experienced cognitive impairment.
In addition, they were 82 percent more likely to have difficulties with everyday memory recall, language, and attention, which are all signals of progressive memory deficit dementia.
Dr. Mary Cushman from the University of Vermont College of Medicine, told the BBC that people who have AB blood type should not be overly worried about these findings, since the association we witnessed was relatively small and requires other research for confirmation.
“Until it’s been shown through research, maintain a healthy lifestyle of regular exercise, not smoking, eating a healthy diet, and controlling blood pressure, and blood sugar.” Source
