Rare blood type linked to later life cognitive decline

A neurological research indicates that people with rare blood group may be more prone to cognitive and memory decline in their later life.

The study, conducted by a research team at the University of Vermont College of Medicine in the US, reveals that people with type AB blood, the least common type, may face a particularly high risk of memory loss later in life.

Analyzing over 30,000 people age 45 and above during three years study showed that those with Type AB blood had an 82 percent higher risk of thinking and memory problems.

The analyzed group was compared with 587 people with no cognitive problems, according to the study report published in the journal Neurology.

The difficulties mainly appeared in day-to-day memory, language and attention, which can signal the onset of 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 and dementia," said the study leader Mary Cushman, of the University of Vermont College of Medicine, Burlington. 

"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," she also explained.

The recent study supported an earlier research that “having a certain blood group such as O may give a lower risk for cardiovascular disease, which in turn protects the brain,” the researchers said.
