Blood group 'link to memory loss'

The study supported the idea that having a certain blood group, such as O, may give a lower risk for cardiovascular disease, which in turn protected the brain, the researchers said.

"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," said Dr Cushman.

"Blood type is also related to other vascular conditions like stroke, so the findings highlight the connections between vascular issues and brain health. More research is needed to confirm these results."

Commenting on the study, Dr Simon Ridley, head of research at Alzheimer's Research UK, said the research did not look at risk of dementia, and it was too early to say whether AB blood group might be linked to a higher risk of the condition.

"Current evidence suggests the best ways to keep the brain healthy are a balanced diet, not smoking and regular exercise," he said.

研究者称，特定血型的人，比如O型血的人，患有心血管疾病的风险较低，这会保护大脑，这一研究支持了这一观点。

库什曼博士称：“我们的研究关注血型和认知损伤风险，但是，一些研究已经表明，诸如高血压，高胆固醇和糖尿病等因素会增加认

知损伤和痴呆的风险。血型也和其他的血管情况相关，比如中风，因此，研究强调了血管问题与大脑健康之间的联系。为确认这些结果还需要更多进一步研究。”

英国阿尔茨海默病研究中心的所长西蒙·芮德利博士评论了这一研究，称研究并为关注痴呆的风险就断言AB型血的人可能会有更高的认知损伤风险为时过早。

他说：“当前研究表明，保持大脑健康的最佳方式就是保持合理膳食，不抽烟以及规律运动。”
